In January 2006, the flash flood in Panti Sub-district was a national disaster, causing damage to building infrastructure and fatalities. From this incident, it is necessary have mitigation by providing map of distribution inundation using 2D hydraulic model provide information regarding extent study area. Due limited DEM data for modeling, use UAV images DSM with good higher resolution. This a...

On January 2019, the biggest flood in last decade struck Gowa and Makassar. The claimed enormous number of victims caused severe damage to many buildings; this can be anticipated by Flood Routing. This study aims analyze hydrograph, propagation time, determine inundation model during downstream Bili-Bili reservoir. research was conducted through three phases: delineation watershed using ArcGis ...

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...

Bridges are crucial for transporting people and goods, but their failures can be catastrophic, resulting in loss of life property. This study assessed the flood stage selected bridges (Alaafin Avenue, Seven-Up, Oluyole) along Ona River, Ibadan, Nigeria, using a one-dimensional model called Hydraulic Engineering Center-River Analysis System (HEC-RAS). The requires two major input data: geometric...

An application is presented of a new methodology for the real-time operations river-reservoir systems. The based upon an optimization/simulation modeling approach that interfaces optimization with one and/or two-dimensional unsteady flow simulation model (U.S. Army Corps Engineers HEC-RAS). also includes short-term rainfall forecasting, and U.S. HEC-HMS rainfall-runoff modeling. Both forecasted...
