Abstract: Infiltration or transmission losses in ephemeral stream channels are an important part of the water balance in arid and semiarid regions. The governing equations for movement of flood waves subject to transmission losses are simplified through a time-averaging process to produce an ordinary differential equation describing transmission losses as a function of distance, upstream inflow, lateral inflow, channel dimensions, flow duration statistics, and effective hydraulic conductivity. The resulting equation has an analytic solution, and transmission losses throughout an entire channel network can be estimated by cascading the outflow from one or more upstream channel reaches as inflow to subsequent downstream reaches.
