Seepage Intensities Increase Roughness in Steady Non‐Uniform Flow Within Rigid Cylindrical Vegetation

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Theories for flow conveyance within aquatic vegetation have predominantly been developed for impermeable beds thereby overlooking key interactions between hydraulic and hydrologic drivers. To begin addressing this overlook, the hydrodynamic properties of emergent rigid cylindrical vegetation covering a pervious gravel bed are experimentally ...

Aplikasi Program HEC-RAS 5.0.3 Pada Studi Penanganan Banjir

Elkawnie, 2018
Sungai Krueng Tukah memiliki DAS 59,51 Km2 dan panjang 25 Km serta bermuara di Selat Malaka. Sungai Krueng Tukah mengalami perubahan  kondisi sungai, tataguna lahan dan pertumbuhan penduduk sehingga sungai tidak lagi berfungsi secara optimal. Banjir pada Sungai Krueng Tukah menimbulkan kerusakan bangunan, lahan pertanian, dan lingkungan hidup.

Spatial Modeling of Flood Hazard in Addis Ababa Using Geographic Information System (GIS) and Information Gain Ratio (IGR) Method

Journal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT Floods are one of nature's most disturbing catastrophes, resulting in infrastructure damage, property devastation, and mortality. In Addis Ababa, flooding has significantly impacted residents and caused millions' worth of property damage in the last decade alone. It is continuously threatening and affecting city residents.

Analyzing Synthetic Stage‐Discharge Rating Curves and Riverine Flood Inundation Maps Derived From Global‐Scale Hydrologic and Hydraulic Modeling

Journal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT Synthetic rating curves (SRCs) are often used to translate streamflow forecasts into flood inundation maps. Previous studies have investigated the development and errors in SRCs at local, regional, and continental scales. In this analysis, we used the latest global methodology and datasets to develop SRCs for use in flood inundation map ...

A Dam Break Analysis Using HEC-RAS

Journal of Water Resource and Protection, 2011
This paper firstly described the dam break in the aspects of theories and models. Break parameters prediction, the understanding of dam break mechanics, peak outflow prediction were shown as the essential for the dam break analysis, and eventually determined the loss of the damages.

Bridge Clogging by Loose Sediment in Mountain Streams: A Practical, Physics‐Based Numerical Approach for Use in Hazard Mapping

Journal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT The clogging of bridges by loose sediments is a phenomenon that has so far been little studied in the literature but plays a decisive role in determining the spatial distribution of hazards in mountainous areas affected by these events. Lacking a systematic approach, in this paper, we propose a simple scheme describing the physics of bridge ...

Improvement of Rating-curve by HEC-RAS

Journal of the Environmental Sciences, 2004
HEC-RAS model is used for estimation of rating-curve of Musung in Wi stream. Discharge is computed from stage estimated by HEC-RAS model, is compared with the discharge of water surface slope method. The relative deviation of observed and computed discharge is 5.37%, and shows as a good results. A rating-curve by HEC-RAS model shows better results than

Flood Early Warning Systems in the White Volta Basin, Ghana: Challenges and Opportunities

Journal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT Flooding in Ghana's White Volta basin has caused widespread displacement, fatalities, and damage to infrastructure and livelihoods in agriculturally dependent communities. Despite the presence of national agencies such as the Ghana Meteorological Agency (GMet) and Ghana Hydrological Authority (GHA), early warning capabilities remain ...
