Abstract: Similarity solutions for the overland flow‐infiltration problem are obtained by use of a physically‐based mathematical model. The mathematical model is founded on the kinematic equations of overland flow and the Green‐Ampt ...

Abstract: A desk‐top method is presented to size detention ponds and the outlet facilities for multiple return periods. The method is based on the usual reservoir routing technique, which couples the hydrologic storage equation with ...

Abstract: A design aid is presented for sizing stormwater infiltration structures. The proposed procedure is based on the hydrological storage equation for an infiltration structure coupled with the Green and Ampt infiltration ...

Abstract: The original Horton equation is valid only if the rate of rainfall is always higher than the infiltration capacity of the soil throughout a rainfall-infiltration process. This technical note presents a modified Horton ...

Abstract: A mathematical model, which is founded on the kinematic‐wave and Green‐Ampt equations, is presented for the conjunctive overland flow‐infiltration process. Within the context of this model, it is shown that overland flow ...

Abstract: A mathematical model based on kinematic overland flow and Green‐Ampt infiltration is developed to calculate the time of concentration of overland flow on a rectangular plane surface. The governing equations of the ...

Abstract: A desktop method is presented to analyze or size detention ponds and outlet facilities. Different initial conditions are allowed. When used for design purposes, the method determines the size of the outlet facility for a ...

Abstract: An explicit formula is presented to determine the time of concentration of pervious, plane rectangular catchments. Unlike many existing empirical equations, the proposed formula expresses the time of concentration in terms ...
