This study was conducted to map flood inundation areas along the Manafwa River, Eastern Uganda using HECRAS integrated with SWAT model. The mainly sought evaluate predictive capacity of by comparisons streamflow observations and derive, HECRAS, maps. Changes in Land-use/cover showed decrease forest wetlands, conversions into farmlands built-up from 1995 2017 have resulted increased annual surfa...

Banjir merupakan salah satu bencana alam yang sering melanda berbagai daerah di Indonesia. Penelitian ini dilatarbelakangi oleh kondisi drainase Kampus USU dengan luas lahan ±143 Ha terlihat tidak mampu menampung besarnya debit masuk baik disebabkan daya tampung lebih kecil dari ada, kurangnya perawatan maupun sistem pengaliran dan pembuangan sesuai lagi lingkungan sebagainya. Studi bertujuan u...

Abstract The article describes the process of redesigning intake structure fish pass at Žilina water in Slovakia. existing does not meet passability requirements for target species migratory fish. A design utilizing windows various levels that cover fluctuations level reservoir, which has been successfully used other structures, proposed. new was subjected to hydraulic calculations and simulati...

For the modelling of the flood routing in the lower reaches of the Freiberger Mulde river and its tributaries the one-dimensional hydrodynamic modelling system HECRAS has been applied. Furthermore, this model was used to generate a database to train multilayer feedforward networks. To guarantee numerical stability for the hydrodynamic modelling of some 60 km of streamcourse an adequate resoluti...

Flood wave propagation in river channel flow can be enunciated by nonlinear equations of motion for unsteady flow. It is difficult to find analytical solution of these non-linear equations. Hence, in this paper verification of the finite element model has been carried out against available numerical predictions and field data. The results of the model indicate a good matching with both Preissma...

A dam break is a low-probability, high risk catastrophe event that extremely destructive and has substantial negative socio-economic impact on downstream nearby areas. Simulating breach analyzing flood propagation from those events vital for identifying minimizing the risks associated of location. This study intended to anlayse effect overtopping failure two scenario (a) base-case (scenario wit...
