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 ...

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.ABSTRACT The Mediterranean region is characterized by the occasional occurrence of intense rainfall events. Along with lithological, geomorphological, and land use factors, these events influence the hydrosedimentary dynamics of drainage basins, potentially causing torrential floods.

Use of HEC-HMS in floodwave propagation simulations
Revista de Investigación de Física, 2020 A delicate feature of the flood propagation simulation performed by the program HEC-1 with theoption of the modified Puls method with normal flow approximation is constituted by the estimationof the quanta parameter NSTPS. While it is recognized to be a parameter that one should calibrate, itis usually recommended that it be estimated as the ratio ...

Potential Improvements for HEC-HMS Automated Parameter Estimation [PDF]
, 2006 Abstract : Model independent enhancements and adaptations to the Gauss-Marquardt-Levenberg (GML) method of computer-based parameter estimation are described and demonstrated as potential improvements to existing HEC-HMS automatic calibration capabilities. In contrast to existing HEC-HMS automated parameter estimation capabilities, these methods support

Evaluation of the HEC-HMS model for the hydrological simulation of a paramo basin
DYNA, 2019 In this study, the performance of the HEC-HMS model was evaluated for the simulation of rain-runoff processes in a paramo basin of approximately 21. 8 km2, south of Ecuador. The calibration and validation comprises the period of July-2013 to June-2016 with daily data.

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.Shifting climatic averages and extremes are affecting both environmental and anthropogenic communities. This is a growing concern, especially for social–ecological systems (SES) such as lakes and their catchments, which integrate ecological and societal subsystems.

Evaluation and Comparison of the Artificial Neural Network and the HEC-HMS Models in the Simulation of the Rainfall-Runoff process and the development of Hydrograph in the Kasilian representative Basin [PDF]
مهندسی منابع آب, 2018 The Rainfall-runoff process is a non-linear and a very complicated phenomenon. As collection of the reliable data is difficult, time consuming and expensive, hydrologists resort to the simulation of such events using the so-called black box models such ...

Study on the combination of HEC-HMS and ArcGIS for the upstream of xindian river
, 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，
