Abstract: Despite the importance of overland time of concentration on the design discharge, engineers are often bewildered by the array of formulas available in the literature without knowing the accuracy of each formula. This ...

Abstract: To simulate a runoff hydrograph from an overland plane or from a catchment that is subject to natural rainfall, the use of a computer model is essential. To develop such a model, among other parameters, the modeler is ...

Abstract: For a catchment comprising a network of open channels and overland planes, the time of travel and the equilibrium detention storage in the channels have profound effects on the runoff characteristics of the catchment. For ...

Abstract: Time of concentration of overland flow is an important parameter in many hydrologic design methods. This technical note traces the evolution of the kinematic wave time of concentration formulas for overland flow only. It ...
