Development of WEP Model and Its Application to an Urban Watershed
HYDROLOGICAL PROCESSES Hydrol. Process. 15, 2175–2194 (2001) DOI: 10.1002/hyp.275 Development of WEP model and its application to an urban watershed Yangwen Jia,1* Guangheng Ni,1 Yoshihisa Kawahara2 and Tadashi Suetsugi3 1 Urban River Division, Public Works Research Institute (PWRI), Asahi, Tsukuba City 305-0804, Ibaraki Prefecture, Japan 2 Department of Safety Systems Construction Engineering, Kagawa University, Kagawa 761-0396, Japan 3 River Hydraulics Division, Public Works Research Institute, Tsukuba, Japan Abstract: A distributed hydrological model, water and energy transfer processes (WEP) model, is developed to simulate spatially variable water and energy processes in watersheds with complex land covers. In the model, state variables include depression storage on land surfaces and canopies, soil moisture content, land surface temperature, groundwater tables and water stages in rivers, etc. The subgrid heterogeneity of land use is also taken into consideration by using the mosaic method. For hydrological processes, evapotranspiration is computed by the Penman–Monteith equation, infiltration excess during heavy rains is simulated by a generalized Green–Ampt model, whereas saturation excess during the remaining periods is obtained by doing balance analysis in unsaturated soil layers. A two-dimensional simulation of multilayered aquifers is performed for groundwater flow. Flow routing is conducted by using the kinematic wave method in a one-dimensional scheme. For energy processes, short-wave radiation is based on observation or deduced from sunshine duration, long-wave radiation is calculated according to temperatures, latent and sensible fluxes are computed by the aerodynamic method and surface temperature is solved by the force–restore method. In addition, anthropogenic components, e.g. -
Flood Control and Small-Scale Reservoirs
River Basin Management VI 51 Flood control and small-scale reservoirs H. Gotoh1, Y. Maeno1, M. Takezawa1 & M. Ohnishi2 1Nihon University, Tokyo, Japan 2Funabashi City Municipal Office, Funabashi, Chiba, Japan Abstract Flood control defenses such as levees, dams, reservoirs, and weirs are used to prevent rivers from bursting their banks. Among these defenses, the construction of large-scale dams has recently become an important topic of discussion in countries around the world. It is important to construct large dams to secure water for drinking, irrigation, electricity, and industrial use. However, leaders and well-informed persons in many fields have argued that the development of large-scale dams destroys the natural environment, forces residents of entire villages to leave their homes, and consumes too much time and money. In Japan, large-scale dams were initially constructed mainly to supply electric power, but the purpose of dams has now shifted to water supply or flood defense. Whether large-scale dams are necessary is now a source of contention throughout the world, with several advanced nations calling for the removal of dams. The present paper, taking as an example a small-scale reservoir for flood control in a small river in Funabashi City, Japan, makes the following main conclusions: small-scale reservoirs were used as a measure of flood control in many parts of Japan in the past; terraced paddy fields as well as small-scale reservoirs play an active role in flood control measures in place of large dams; flood control measures are reinforced by connecting small-scale reservoirs; small-scale reservoirs spare the environment from destruction caused by the construction of large dams; and small-scale reservoirs can be utilized as recreation sites for fishing, swimming, and walking. -

Plankton Community Structure in Saguling
17th World Lake Conference, Lake Kasumigaura, Ibaraki, Japan, 2018 P1-1 Plankton Community Structure in Saguling Dam Fattreza Ihsan1, Feni Hastuti1, Regina Leny1, Ika Puspitasari1, Alya Fatina Diandari1, Nisrina Sukriandi1, Beo Nada Rezky1, and Rizkyanti Aulia1 1Institut Teknologi Bandung Keywords: Saguling Dam, plankton biodiversity, Floating Net Cage, fisheries, organic waste ABSTRACT Saguling Dam is a semi natural man-made ecosystem which is located at Bandung District, West Java. For the time being, the characteristic of Saguling Dam is changing because of human activity, such as floating net cage (FNC) activity. FNCs on Saguling Dam increase organic waste level at Saguling Dam. This causes plankton communities to change around the FNCs on Saguling Dam. Plankton communities can be used as an aquatic biologic parameter. Aspects that were inspected are the composition, abundance, and diversity of plankton species. This research’s goal is to compare plankton communities at 3 different state of FNC: dense, distant, and vacant; at three different lake depths: 0, 3, and 6 meter(s) below the surface. Plankton communities on each point of point sample is tested using Sorensen’s index. This research’s conclusion is that the diversity index at Saguling Lake is at medium level; the highest plankton abundance is at 3 meters depth, and the highest predominant genus for phytoplankton is Trachelomonas and for zooplankton is Paradileptus. Sorensen’s index results show that there are similiarities of plankton communities at several point samples. 1. INTRODUCTION Saguling Dam is a semi-natural man-made ecosystem which is located at Bandung District, West Java. The construction of Saguling Dam is done by stemming the flow of Citarum River. -
