When reservoirs are built, they subject to some degree of sedimentation. This happens because the increase in wetted area reduces flow velocity. As a result, sustaining forces sediments diminished. One mechanism assess reservoir sedimentation is through physical models, which provide data for numerical models. parameters that needs be input into model Manning coefficient. Thus, aim this study w...

The objective of this study was to assess the performance form-based and process-based models, local-scale reach-scale used examine bank retreat sediment transport in stream restoration. evaluated models were Bank Erosion Hazard Index (BEHI), Assessment for Nonpoint Source Consequences Sediment (BANCS), Stability Toe Model (BSTEM), HEC River Analysis System (HEC-RAS 1D). Model-to-model assessme...

Rapid and reliable flood information is crucial for minimizing post-event catastrophes in the complex river basins of world. The Chenab River basin one world, facing adverse hydrometeorological conditions with unpredictable hydrologic response. Resultantly, many vicinities along undergo destructive inundation, resulting huge life economic losses. In this study, Hydrologic Engineering Centre–Hyd...

This study highlights the simulation of tsunami cases using HEC-RAS 6.1. The primary aim is to evaluate capability software in performing due its standalone computational framework (pre-processing, execution, and post-processing stages), making modeling process interactive. model accuracy was tested against some benchmark wave propagation, including analytical solutions, laboratory experiments,...

Sungai Cisadane berpotensi menimbulkan banjir di Tangerang, khususnya Bendungan Pasar Baru hingga Jembatan Kedaung. Hal ini disebabkan oleh penyempitan aliran dan pendangkalan sungai hilir, serta perubahan penggunaan lahan sepanjang bantaran Cisadane. Penelitian bertujuan untuk mengidentifikasi lokasi, kedalaman, sebaran genangan air menggunakan model permanen keluaran HEC-RAS (1D) pada tanggal...
