Calibration and Validation of HEC-HMS Model for Chalakudy River Basin

International Journal of Environment and Climate Change, 2021
Prediction of flood prone areas in a basin and evolution of the impact of climate change on water resources needs a correct estimation of the availability of water which will solely be achieved by hydrological modelling of the basin. However, modelling the hydrology of a basin is a complex task and models should be well calibrated to increase user ...

On the Clark Unit Hydrograph Model of HEC-HMS

Periodica Polytechnica Civil Engineering, 2017
A mathematically correct form of the linear storage element’s routing equation is specified requiring only a slight modification of the existing HEC-HMS routine. The new formulation, unlike the current version in use, is unconditionally stable as long as the time step and the storage coefficient values are trivially specified as positive numbers.

Coupling WRF with HEC-HMS and WRF-Hydro for flood forecasting in typical mountainous catchments of northern China [PDF]

Natural Hazards and Earth System Sciences
The atmospheric–hydrological coupling systems are essential to flood forecasting because they allow for more improved and comprehensive prediction of flood events with an extended forecast lead time.

Compatibility of personal care thickening polymers in sulphate‐free surfactants

International Journal of Cosmetic Science, EarlyView.
Phase behaviour for alpha olefin sulfonate surfactant 10–15 wt% combined with 1 wt% sodium carboxy methyl cellulose, clearly indicating the sensitivity in miscibility when adding various levels of background salt. Abstract Objective Formulators today know that when traditional surfactants and polymers are replaced new problems occur. What was before a ‘

Study on the combination of HEC-HMS and ArcGIS for the upstream of xindian river [PDF]

, 2010
碩士本研究為探討美國陸軍工兵團發展之水文模式系統(HEC-HMS)其模式理論背景，討論各種模式方法須輸入之參數，並將HEC-HMS 應用在新店溪上游集水區，模擬歷年五場颱風之暴雨逕流。前置作業則將地理資訊系統軟體ArcGIS 與水文模式系統軟體HEC-HMS 做結合，即以ArcView 為操作平台，利用工具ArcHydro 與HEC-GeoHMS 模組分劃集水區並擷取相關地文因子，達到自動建置HEC-HMS 之輸入檔及水文元件之目的。HEC-HMS 主要由三大模組構成，分別為流域模組、氣象模組和控制規格，

Streamflow Spatial Correlation Length Increases During Storms and Its Application in Data Assimilation Improves Streamflow Predictions

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The spatial correlation of streamflow in a river network captures how flows at different locations relate to one another and influence the downstream response. In this study, we analyze the spatial correlation of streamflow and rainfall during storm events in three Texas watersheds: San Antonio (2015 and 2016 storms), Guadalupe (2018 storm ...
