Application of the HEC-HMS model for runoff simulation in a tropical catchment

Environmental Modelling and Software, 2013
Hydrologic simulation employing computer models has advanced rapidly and computerized models have become essential tools for understanding human influences on river flows and designing ecologically sustainable water management approaches. The HEC-HMS is a reliable model developed by the US Army Corps of Engineers that could be used for many ...

Developing an Efficient Auto-Calibration Algorithm for HEC-HMS Program

Water Resources Management, 2016
Two auto-calibration methods, namely Nelder-Mead (NM) and Univariate-Gradient (UG) and a manual approach are available for calibrating the HEC-HMS program. However, their being either inefficient or time consuming makes it difficult to work with HEC-HMS especially when using a snowmelt module in a continuous mode. The main objective of this paper is to

Simulation of runoff using HEC-HMS for ungauged catchment

AIP Conference Proceedings, 2021
Hydrological modelling is a conceptual representation of a complex characteristic of real hydrologic features which developed to understand, analyse, predict and manage water resources in a watershed. The simulation of surface runoff was developed in the catchment of centre in Perlis State by using Hydrologic Modelling System (HEC-HMS).

Event and Continuous Hydrologic Modeling with HEC-HMS

Journal of Irrigation and Drainage Engineering, 2009
Event hydrologic modeling reveals how a basin responds to an individual rainfall event (e.g., quantity of surface runoff, peak, timing of the peak, detention). In contrast, continuous hydrologic modeling synthesizes hydrologic processes and phenomena (i.e., synthetic responses of the basin to a number of rain events and their cumulative effects) over a

Integration of HEC-RAS and HEC-HMS with GIS in Flood Modeling and Flood Hazard Mapping [PDF]

Sustainability
SustainabilityFloods are among the most devastating disasters in terms of socio-economics and casualties. However, these natural disasters can be managed and their effects can be minimized by flood modeling performed before the occurrence of a flood.

Coupling HEC-HMS with Atmospheric Models for Prediction of Watershed Runoff

Journal of Hydrologic Engineering, 2002
The operation of reservoirs in the Sierra Nevada mountains of California for flood control relies on forecasts of reservoir inflows. In the past, accurate forecasts of the reservoir inflows resulting from watershed runoff have been made, but only after the water has entered the main channel.

Assessment of flood flow using HEC-HMS software

Materials Research Proceedings
Abstract. This research developed an alternative approach for flash flood modeling in a region by the use of physiographic features, surface water models like ARCGIS (Aeronautical Reconnaissance Coverage Geographic Information System), HEC-HMS (Hydrologic Modeling System-Hydrologic Modeling System), and a GIS (Geographic Information System).

Modeling Surface Runoff in Surakarta Using HEC-HMS and DEM

Turkish Journal of Civil Engineering
Surakarta, Central Java, experiences recurrent urban flooding from impervious surfaces, inadequate drainage, and complex topography. This study applied HEC-HMS with 30-meter DEM data to simulate surface runoff in the Pepe River and Bengawan Solo subbasins.
