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.

Hydrological modelling of wadi Ressoul watershed, Algeria, by HEC-HMS model
Journal of Water and Land Development, 2016 AbstractThis study presents a flood estimation model for wadi Ressoul in El Berda watershed, north east of Algeria. To ensure the overall consistency of simulated results, it is necessary to develop a validation process, particularly in regions where data are scarce or limited and unreliable.
