Suitability of HEC-RAS for Flood Forecasting [PDF]
Canadian Water Resources Journal, 2005 At present, most river flood forecasts are conducted using a two-step procedure. First, flood routing is conducted, normally using hydrological models. The resulting flood peaks are then converted to water level forecasts using a steady flow hydraulic model, such as HEC-RAS.

Sedimentation Analysis of Kabul River by Using HEC-RAS
Journal of The Institution of Engineers (India): Series A, 2023 Abstract Rivers are the main and easily available source of water for various uses, and one of the main aims of river engineering is to control sedimentation and erosion. Due to strategic and environmental circumstances, the Kabul River is a well-known river in Afghanistan that attracts much interest for its water project design, existing ...

Comparing HEC-HMS and HEC-RAS for Continuous, Rain-on-Grid, Urban Watershed Modeling
HydrologyThe application of two-dimensional (2D) hydrologic and hydraulic modeling tools is increasing for overland flow simulation, as they represent spatial changes in depth, velocity, and flow conditions more accurately.

Perbandingan Hasil Pemodelan Aliran Satu Dimensi Unsteady Flow dan Steady Flow pada Banjir Kota
Media Komunikasi Teknik Sipil, 2016 One dimensional flow is often used as a flood simulation for the planning capacity of the river. Flood is a type of unsteady non-uniform flow, that can be simulated using HEC-RAS.

Hybrid GNN and temporal encoder models for flood forecasting in the Vu Gia–Thu Bon River Basin
River, EarlyView.Abstract Flood forecasting in river networks requires models that can capture both spatial dependencies across river basins and the temporal dynamics of hydrological processes. This study proposes a hybrid approach combining Graph Neural Networks (GNNs) with temporal sequence models, such as Long Short‐Term Memory (LSTM) networks and Transformer ...
