Significant advances have been made over the last decade in the development of software for surface irrigation analysis. WinSRFR is an integrated tool that combines unsteady flow simulation with tools for system evaluation-parameter estimation, system design, and operational optimization. Ongoing efforts are focusing on coupling the simulation engine to physically-based infiltration modeling applications and adding modules for simulation of sediment and solute transport. The current and planned integration of these components have made evident the need to re-engineer the SRFR simulation engine and reevaluate some of its computational components. This paper briefly discusses WinSRFR and provides an overview of surface irrigation modeling advancements relevant to the WinSRFR project.
