Estimation of the HEC-HMS model parameters in data-scarce regions. Application to the Ouergha watershed (Sebou, Morocco) [PDF]
The availability, accessibility and quality of data are significant obstacles to hydrological modelling. Estimating the initial values of the hydrological model´’ ’s parameters is a laborious and determining task requiring much attention.

Impacts of land use change on streamflows in the Damansara watershed, Malaysia. [PDF]
Land-use change has significant impacts on hydrologic processes at the watershed level. In this study, hydrologic models and spatial data were used to assess the effects of land-use changes and predict the effects of two future land-use scenarios on the ...

The influence of spatial discretization on HEC-HMS modelling: a case study [PDF]
The spatial discretization of a watershed can directly influence the derived outputs of hydrological models Conclusive guidelines regarding the proper level of spatial discretization have not yet been established due to the great diversity of models calibrated parameters and topographic and geospatial characteristics of study areas The objective of ...

Hydrologic Modeling for Sedimentation in Hemrin Reservoir Using HEC-HMS
Hemrin dam is an important dam in Iraq located on Diyala river which is considered as main tributary of Tigris. The sedimentation is very difficult problem and is considered the major problem affecting the utilization of the dam. HEC-HMS 4.1 software was used to made a simulation for sedimentation in Hemrin reservoir in order to estimate the amount of ...

A hydrological model for Ayamama watershed in Istanbul, Turkey, using HEC-HMS [PDF]
Abstract In order to overcome the flood risk in urbanized regions with high population density, generation of hydrological models is essential. The aim of this study is to generate a hydrological model for the Ayamama watershed by using HEC-HMS, simulate the flood event that occurred in Ayamama River in Istanbul, Turkey, on September 9 ...

Evaluation of the HEC-HMS model for the hydrological simulation of a paramo basin
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.

On the Clark Unit Hydrograph Model of HEC-HMS
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.
