Estimation of parameters of a hydrologic model is undertaken using a procedure called “calibration” in order to obtain predictions as close as possible to observed values. This study aimed to use the particle swarm optimization (PSO) algorithm for automatic calibration of the HEC-HMS hydrologic model, which includes a library of different event-based models for simulating the rainfall-runoff pr...

Rapid and reliable flood information is crucial for minimizing post-event catastrophes in the complex river basins of world. The Chenab River basin one world, facing adverse hydrometeorological conditions with unpredictable hydrologic response. Resultantly, many vicinities along undergo destructive inundation, resulting huge life economic losses. In this study, Hydrologic Engineering Centre–Hyd...

The objective of the study was to configure Hydrological Modeling System (HEC-HMS) in such a way that it could simulate all-important hydrological components (e.g., streamflow, soil moisture, snowmelt water, terrestrial water storage, baseflow, surface flow, and evapotranspiration) Three-River Headwater Region. However, problem we faced unsatisfactory simulations these components, except stream...
