Direct Solution to Surface Irrigation Advance Inverse Problem

A modification to the double‐sweep routine commonly used to solve the continuity and momentum equations for surface irrigation models has been developed to allow the solution of one global parameter at each time step. Coefficients for the double‐sweep routine are presented for the Kostiakov infiltration parameter k, the Manning n, and the time step δt. A procedure is also developed for determining the entire infiltration relation (e.g., both...
