The primary objective of this study was to examine the quality volunteered geographic information (VGI) data for flood mapping Hurricane Harvey. As a crowdsourcing platform, U-Flood project mapped flooded streets in Houston metro area. This research examines following: (1) If there are any significant differences water depth (WD) among hydraulic and hydrologic (H&H) model, Federal Emergency...

Banjir merupakan masalah yang rutin dialami oleh masyarakat di wilayah Sungai Kali Lamong, khususnya Desa Jono dan Tambakberas, Kecamatan Cerme, Kabupaten Gresik. Oleh sebab itu untuk mengurangi banjir, diperlukan pembangunan tanggul. Akan tetapi, tanggul memerlukan adanya pengadaan tanah pada lokasi direncanakan. Tujuan dari studi ini adalah melakukan analisa banjir dengan program HEC-RAS, kel...

Abstract Flood catastrophe continuously hit Malaysia through monsoonal flood and flash as well posing threat towards people, infrastructure environment. Batu Pahat is among the district in Johor affected by disaster for almost every year. This study conducted to determine hydraulic hydrological characteristic ability of drainage system Parit Besar Jalan Pontian-Batu catchment area at using HEC-...

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,...

The application of numerical models to understand the behavioural pattern a flood is widely found in literature. However, selection an appropriate hydraulic model highly essential conduct reliable predictions. Predicting discharges and inundation extents are two most important outcomes simulations stakeholders. Precise topographical data channel geometries along suitable required accurately pre...

River renaturation can be an effective management method for restoring a floodplain’s natural capacity and minimizing the effects during high flow periods. A 1D-2D Hydrologic Engineering Center–River Analysis System (HEC-RAS) model, in which flood plain was considered as 2D main channel 1D, used to simulate flooding restored reach of Spree River, Germany. When computing this finite volume diffe...

Abstract The hydrodynamic model is essential for building a water quality rivers, lakes, estuaries, and other systems. Most software, such as HEC-RAS, can perform complex surface body limitations to represent the corresponding area. In contrast, models, like WASP, simulate wide range of contaminants in multidimensional geometry reservoirs. Still, it requires flow information from separate model...
