 This study was conducted to clarify the effects of a series of cascade run-of-river hydropower system on the stream ecosystem. To evaluate the stream ecosystem, the Odum's concepts of stream metabolism were adopted with the field survey which composed of continuous logging of water environmental variables such as dissolved oxygen concentrations and simultaneous practical sampling on attached algae and river water. The study locations were set above and below a run-of-river hydropower weirs and plants, with particular references to their reducing waters. According to the results, daily gross production, community respiration and their ratio could be evaluated at each of the conditions. It also could be clarified the cumulative effects of the hydropower generations with the degeneration of the ratios between gross productions and respirations.

Geology is one of the crucial components for defining riverbed materials and textures especially in mountainous streams, which might effects on their aquatic communities. In this study, the Kushida River basin, central Japan, composed of different geologic units such as plutonic, metamorphic, and sedimentary terrains, was selected to clarify the relationships between riverbed textures and benthic macroinvertebrates. We conducted field surveys at riffle and pool units in each of the 18 stations (three sites each for six tributaries) by taking into account their watershed geologies and landuses. Sediment samplings, topographic measurements and water quality monitoring (temperature, pH and electric conductivity) were undertaken at these sites. The individuals of macroinvertebrate were picked out from each of the sediment samples and identified at the species level with six “life types”, whereas their residual samples were used to analyze the riverbed textures. The topographic, geologic and ecological differences among each of locations in the tributaries have been discussed with the one / two way ANOVA tests. According to the results, it could be understood that there are strong relationships among the watershed geologies, the physical characteristics of riverbed textures and the features of species and life type compositions of benthic macroinvertebrates.

The present study is conducted for predicting tributary sediment flux in a river system with heterogenic topography, geology and lithology. Physicochemical characteristics of stream bed materials in the watershed area were clarified by analyzing field measurement of their topography and sediments and two kinds of laboratory experiments of these sediments by employing a concrete mixer and the X-ray fluorescence (XRF) spectrometer. We could relatively evaluate the amount of sediment supply from each tributary with the each size and element distribution of sediment (from sieving and XRF results) which was produced in its watershed contained various topography and geology in a river system.

Net-spinning caddis larvae set up nests on the substratum in a cobble river. Their abundance is clearly existed on the substratum with fewer disturbances, and moreover causes “substratum adhesion” which suppresses the flux of bed-load transport because they bind a large amount of bed-materials. In this paper, we modeled the population dynamics of the net-spinning caddis larvae (Stenopsyche sp. and Macrostemum radiatum) by taking into account of the different dynamics between the number of their individuals and their individual growths and the conventional knowledge about their responses of emigration, immigration and environmental capacity to various flow conditions. Combining the numerical simulations of the caddis population dynamics and the flow computation in a study reach with our experimental results about the substratum adhesion due to the caddis inhabitations enabled to explain the actual substratum adhesion with temporal changes in the cobble river with fewer disturbances.

<p>From the records of Nagoya City, we mapped 232 evacuation sites and the extent of inundation during the two-month period caused by Isewan Typhoon. In addition, we mapped the evacuation sites of 51,231 evacuees within 8 days of the disaster and 32,376 evacuees on the 21 days after the disaster. Comparing these two sets of data, it was found that between the 8 and 21 days after the occurrence of the disaster, evacuations in areas that were not inundated or two areas that were inundated but had already been drained were progressing, while evacuations in inundated areas were continuing.</p>

<p> Sand cover rate (SCR) is an important factor to explain the foraging habitats of ayu (<i>Plecoglossus altivelis</i>). Hence, a module of riverbed variation in a gravel-bed river with bimodal sediments was developed. The module calculated SCR, and the changes in SCR were defined as being driven by sand transport in the form of a suspended load that is deposited on stones (e.g., cobbles or pebbles) and in the interstices of stones. The prediction accuracy was examined by comparing the calculated SCR with the SCR measured in the field. The results showed that the spatial pattern of sand deposition/erosion predicted by the module was almost close to the measured one, though the predicted SCR tended to be higher/lower than the measured value. Chronological changes in the SCR calculated by the module suggested that sand deposits started forming along shorelines after the peak of a flood and then expanded toward the centers of the flow in channels in the end stage.</p>

The use of former edition maps for disaster risk learning is effective, but requires
proficiency of instructors. In this study, we developed a spatiotemporal GIS with many
layers in addition to the former edition maps, and applied it to a special exhibition on the
Typhoon Vera (the Isewan Typhoon) in 1959, Japan. And we evaluated the effectiveness of
spaciotemporal GIS from the system logs and the questionnaire survey to the visitors. The
results showed that a certain percentage of users used the spaciotemporal GIS for scenariobased
learning, and this percentage increased in conjunction with the special exhibition. At
the same time, the results of the questionnaire survey showed an improvement in the user’s
satisfaction. From these results, the effectiveness of the method was confirmed.

This paper proposes a method for estimating flood levels by data assimilation using a state space model to determine the spatial-temporal flood expansion process. The method incorporates flood simulation values to analyze the causal relationship with observation data of river water levels. First, we simulate flood scenarios using a flood simulator with various precipitation patterns to construct time series datasets with high spatial resolutions (5-10m). Then, after estimating the water level in the channels using an auxiliary particle filter, we analyze the inflow and the outflow of flood water for each grid element by improving the state space model to add spatial variables. We evaluated the performance of the proposed method using observation data in Aichi Prefecture, Japan. While the conventional method had an error of approximately 60cm compared to the observation value, our estimation method using the proposed state space model showed a significant improvement, with an error of less than 9cm.

<p>For the evaluation of habitat suitability for fish, hydraulic data that can be easily observed have been
often used. However, it has become essential to consider fish's preference for riverbed environments
modified by artificial sediment supply in gravel-bed rivers. In this study, two types of evaluation methods
were applied on the target river with different riverbed environment in the two diversion channels. These
models are conventional evaluation method based on hydraulic quantity (<i>HSI</i>), and it taking into account
the sand cover on stony riverbed as a riverbed environment in addition to the hydraulic quantity (<i>HSIb</i>). The
prediction accuracy was elucidated by comparing the habitat suitability index calculated from these models
with the spatial distribution of the focal point of Ayu obtained from the field survey. The evaluation of
habitat suitability taking into account the degree of sand coverage (<i>HSIb</i>) was found to be able to evaluate
the focal point of Ayu more accurately than the conventional method (<i>HSI</i>).</p>

<p>The Nigori River is strongly acidic because it has influenced by volcanic activities of Mount Ontake in Japan. In order to understand processes of water quality changes through the mixing of slightly alkaline river, the Denjo River, pH, element concentrations and flow of these rivers were observed. By joining of the Denjo River, pH was raised to near neutrality and Al, Mn, S and Fe concentrations were decreased. In contrast, the contents of these Al, Mn, S and Fe were increased. It is confirmed that at the confluence of the rivers, two effects play roles in changing the element contents. The element contents are changed due to two effects such as the precipitation of elements and the adding of elements from springs and sediments around the rivers. We found that the adding affects contents of Al, Mn, S and Fe more significantly than the precipitation does.</p>

<p>Urban utility gas systems composed of ground facilities such as microcomputer gas meters and gas governors, and buried pipeline networks, which have been widely installed in urban lowland areas. Although these gas systems often have been suffered from river flood inundations, there have been a few conventional works which describe causes and effects of the utility gas outages due to the inundations. The present study proposes the methods to estimate and to integrate such of the utility gas damages as ground facility submersions due to the river floods with levee breaches. We quantitatively evaluate the outage durations in utility gas distribution systems by considering the post-flooding restoration works such as drainage of the inundation water with pumping stations and repairing and exchanging the facilities of gas utility systems. Moreover, we characterize some typical patterns of the utility gas damages by comparing different styles of the river flood inundations.</p>

<p>The growth of aquatic mosses attached to cobbles composes bed material in riffles was confirmed in a river in Japan. Covering bed material with aquatic mosses reduces the biomass of attached algae that is a source of energy for commercial fish. This study focuses on how much and how the aquatic mosses keep their coverage on the river bed in riffles after suffering flood disturbances. Resistance to disturbances due to high-speed water flow and sediment impingement on mosses and the rolling of the cobble attached with mosses was investigated by a laboratory experiment. We observed that intermediate disturbance seems to remove silt in the biofilm but the biomass of mosses had tend to be maintained. Based on visual inspection of moss cover following the experiment, we found that the remaining moss consists of short fresh stems. The relationship between the rate of moss detachment and work due to sediment impingement has investigated and the existence of the optimal work per sediment impingement has been clarified.</p>

<p>River environments consist of many things that are difficult to discern visually because they are hidden underwater. And as ecological processes are complicated andfluctuate and habitats go from a micro to wide-scale ones, it is difficult to observe many of the ecological processes and phenomena on-site. In interpreting the above processes, it is necessary to have an exhibition theory based on an ecological point of view of a river. In this study, we considered a theory on how to understand and visualize ecological processes in a river, with references to ecological exhibitions in aquariums and related facilities. First, we found the viewpoints of the exhibitions by looking at the relation between habitat classification that references past related ecological research and the restricted mattersor trends regarding human perspectives. In addition, in order to create a good ecological exhibition, a typical aqua-scape including the target habitats was selected, and cross-sectional views were extracted from the viewpoint of passing through the relevant space. This showed it is important to reproduce aquatic organisms and vegetation in ecotones, placement of a micro-topography and light that is suitable for the target natural environment. With regards to human perspectives, in order to observe the relationship between livingorganisms and the surrounding environment, we clarified the importance of securing good vantage points and multiple angles of elevation for observing phenomena. Lastly, we considered information media such as illustrations and movies which complement and expand the exhibits and discussed events that are difficult to see with the naked eye. In this way, we showed the effectiveness and applicability of the information media in terms of being able to visualize information by expanding or reducing time.</p>

<p>The present study is conducted for describing the step-pool morphologies of mountainous streams in the watersheds with landslide topography. The physical characteristics of longitudinal channel units in the step-pool morphologies were measured by the field investigations, whereas the geologic and topographic information in their watersheds were collected by the GIS (geographical information system) spatial analyses. The statistical analyses have also been performed to discuss the cause and effect relations by combining the multi-scale spatial information of these mountainous streams and watersheds. Accordingly, the analytical results could explain the effects of watershed properties on step-pool morphology with some of the geo-processes such as sediment runoffs, erosions and depositions due to landslide topography in correspondence with the geological features.</p>

The concepts of stream metabolism were adopted to clarify the impacts of run-of-river hydropower system on the stream ecosystem. We conducted a field survey with logging the continuous data of dissolved oxygen concentration above and below the hydropower dam. In order to estimate the primary production and the community respiration, the practical procedures were employed with collected data of dissolved oxygen concentration according to the Kayaba’s empirical model based on the Odum’s concept. As the results, daily gross production, community respiration and their ratio could be degenerated especially below the dam at low flow conditions. It was also clarified that the availability and limitation of the present method to adopt this kind of environmental impact assessment.

This study was performed to clarify the spatial variation of habitat of <i>Corbicula</i> bivalves (<i>C. japonica</i> and <i>C. leana</i>). A series of field investigations were performed in the Kiso River estuary, in October – November, 2012, with particular references to the existence of a series of groins. We compared the differences of water environment, substrate and diet variables in longitudinal and transverse directions (Two-way ANONA) to grasp the habitat characteristics in different landscapes. Furthermore, correlation and multiple regression analyses for their densities and biomass were applied to clarify the crucial environment variables. As the results, it was clarified that salinity and water depth could be the controlling factors for the biomass of <i>C. japonica</i>, whereas the sediment and salinity factors would effect on promoting the biomass of <i>C. leana</i> and the density of <i>C. japonica</i>.

Riverbed armoring is one of the most significant effects on stream communities caused by upstream dam constructions. Practically, there are some of the mitigation measures to be rehabilitated riverbed environment for conserving river ecosystem. Although the sediment additions below the dams have been applied as one of the effective measures, there are a few findings related to the physical-biological responses. The present study conducts field survey below and above the dam which are tried to be supplied gravel at its downstream, with particular references to benthic fish communities and their habitats. The canonical correspondence analysis for these benthic fish and habitat characteristics could show that the impacts of armoring and the mitigations due to gravel additions have altered the benthic fish fauna, respectively.

<p>Small-scale laboratory experiments were conducted by using sand for understanding the phenomena appearing not only at a levee but also in floodplain and along river bed. The authors are concurrently carrying out the numerical study along the same scenario, and these two approaches may provide us more information to understand the levee breach and successive disaster. In this study, a particular reference is put on levee breach and phenomena appearing on a floodplain in case of a river with higher bed level compared to the floodplain level. The higher bed level brings more rapid propagation of levee breach and widening and more sediment deposition in flooded area. And, sometimes river bed degradation in the upstream of the levee breaching point may cause further risk of levee breach in the upstream reach of the river.</p>

Most gravel-bed rivers show the longitudinal sorting on riverbed materials. This phenomenon is due to combination of the selective sorting and the abrasion in bed material transport processes. We developed the stochastic model of bed-load transport with gravel abrasion processes. Applying this model to some ideal rivers which have different concavities in their longitudinal profiles and different geologies in their watersheds, we examined that the longitudinal sorting of riverbed materials was dependent not only on their selective transport according to the hydraulics, but also on their abrasion processes characterized by their watershed geology and lithology.

Disturbance on riverbed is one of the key factors for controlling habitat condition in the middle reach of rivers, which depends on the frequency of the disturbance. If it was lower degree owing to some kinds of human impacts (e. g., dam operation, erosion control works and so on), it could cause degradation of habitat quality for many organisms in the river like nuisance growth of attached algae on the riverbed.<BR>Therefore, the role of the disturbance on riverbed should be evaluated efficiently, but the convectional study didn't pay attention to it. In the present study, we discuss about the estimation of the role of the disturbance on riverbed by using the effect of detachment of attached algae. Introducing the mechanics of bed-load transport and the impact of the bed-load against riverbed and the relationship between the impact and detachment of attached algae, we can estimate the effect of detachment of it.

Each of the models has been progressed individually.<BR>In this study, we tried to innovate the population dynamics to develop the habitat evaluation method. By discussing about the dynamics of algal growth and the habitat suitability of algae in the middle reach of the Yahagi River, we may identify the theory of population dynamics as one of the necessary viewpoints for habitat evaluation.

In the middle reach of the Yahagi river, the frequency of disturbance on river-bed has been decreased, because of the changes in geomorphology and flow regime after the construction of the Yahagi dam. It relates to the change in the riffle-pool structures that were formed by developing alternate bars.<BR>In the present study, we discuss the change in the riffle-pool structure by using 2D numerical simulation and habitat evaluation method. By employing the frequency of the disturbance on the riverbed as a habitat suitability index, what the typical geomorphology with alternate bars helps the habitat condition to be maintained has been explained.

テーマ：河川の環境学―その先端科学と展示・教育技術―
河川は，水循環において山地・森林と海域を繋ぎ，水と土砂を運んで平野などの水成地形を形成してきました。この働きに伴って栄養塩などが流域の各所にゆきわたることでその生態系は駆動され，そこでの物質変換を通じて人間は種々の恩恵を受けています。
本講義では，第一線で活躍されている講師の方々をお招きし，河川環境に関わる先端科学とその展示・教育技術を紹介いただき，環境問題の実態と対策について体系的に理解することを目的とします。

　減災連携研究センターでは、伊勢湾台風襲来から60年を迎えるにあたり、クラウドファンディング「迫りくる！スーパー伊勢湾台風に備えるために」（7月1日～9月26日、寄附総額255.9万円）を通じてみなさまからのご支援をいただき、調査研究を進めながら減災館の展示を拡充するとともに、「伊勢湾台風から60年」記念事業を企画してまいりました。
　この特別シンポジウム「伊勢湾台風～60年前の教訓と新たに生まれた課題～」は本記念事業の一環として、当時の被災を契機として1961年に設立した名古屋大学土木系教室とともに、土木系教室同窓会「鏡ヶ池会」にも協力いただいて企画いたしました。午前中に開催された「令和元年台風15号19号 緊急報告会」に引き続いての実施ながら、一般市民、行政、企業、研究機関、報道関係等、100名を超える参加者がありました。当日は、減災ギャラリーにて一般社団法人中部地域づくり協会制作の「水害体験VR」について出張展示いただいたことも申し添えます。
　シンポジウムは、野田利弘副センター長／教授（鏡ヶ池会25期生）の進行により、土木系教室の設立経緯や現在の教育研究活動状況を紹介した、加藤準治・大学院工学研究科土木工学専攻教授／主任からの挨拶を皮切りに、3つのテーマに沿った話題提供により構成されました。
　最初のテーマ①「60年前の教訓」では、国土交通省中部地方整備局編集・提供の伊勢湾台風に関する映像を視聴した後、杉野尚夫様（鏡ヶ池会1期生）より、「伊勢湾台風発災当時・直後の様子と教訓」と題する講話をいただきました。テーマ②「中部の成長～60年間の変化～」では、大東憲二・大同大学情報学部総合情報学科教授（鏡ヶ池会16期生）から「地下水の過剰揚水による海抜ゼロメートル地域の拡大」と題して、濃尾平野における地盤沈下過程と現状を、富田孝史・大学院環境学研究科教授（鏡ヶ池会23期生）から「水防災の取り組み」と題して、高潮襲来に備えた防波堤などのインフラ整備の現状を報告いただきました。その後、テーマ③「新たに生まれた課題」では、加藤博和・大学院環境学研究科附属持続的共発展教育研究センター教授（鏡ヶ池会28期生）から「人口・土地利用の変化、交通の大動脈としての中部への機能集中」と題し、名古屋都市圏の成長により生じた新たなリスクについて、戸田祐嗣・大学院工学研究科教授から、「気候変動による台風の強力化」と題し、温暖化を踏まえた将来に向けての対応といった課題に関する話題提供がありました。
　パネルディスカッションでは、水谷法美・大学院工学研究科教授（鏡ヶ池会19期生）のコーディネートにより、伊勢湾台風をどう捉えるのか、また、当時の教訓がどう活かされてきたか、さらには、将来、スーパー台風の襲来に向けて何を考えておくべきなのか、といった問い掛けがなされ、パネリストとなった5名の登壇者が意見を寄せ合う形で進行されました。スーパー台風の襲来に際しては、堤防などのハード整備と広域・事前避難などのソフト対応の取り組みをより一層進めることとともに、高潮による浸水に備えて土地利用を制御し、災害に強いまちをつくっていくこと、などの広範な課題について、会場からの質疑を交えながら活発な情報・意見交換が行われました。最後に、田代喬副センター長／特任教授（鏡ヶ池会35期生）からの挨拶で閉会されました。
　本シンポジウムの開催に際しては、名古屋大学土木系教室を始めとする複数の関係主体の連携・協力により、多数の参画者により実現し得ました。なお、このシンポジウムの様子は、クラウドファンディングに支援いただいた方々（リターンとして速記録をご希望された方々）には冊子として別途報告させていただく予定です。
　末筆ながら、本シンポジウムにご参画いただいた皆様、クラウドファンディング事業にご支援いただいた皆様に改めて御礼申し上げます。
