Abstract: A particularly distinguishing characteristic of ephemeral streamflow is the large role played by infiltration. Infiltration interacts in a complex way with channel flow to control the rate of advance of the wave front, the volume and distribution of infiltrated water, the rates of rise and fall of depth and flow hydrographs, and the peak depths and flowrates of flood flows. This investigation attempts to clarify and explore these interactions via the development of a mathematical model.
