The USDA-ARS U.S. Arid-Land Agricultural Research Center is glad to announce the release of WinSRFR 2.1. People can download a copy of the software from http://www.ars.usda.gov/services/software/software.htm . Key additions and improvements to the software relative to Version 1.2 are:
•
Event analysis: Merriam-Keller analysis now supports all infiltration functions and basins, border, and furrows. Two-point method analysis. Improves the calculation of upstream depth and surface volume with any slope condition, including small and zero slopes.
•
Physical design and operations analysis now supports furrow design and operation; extends performance-contour presentations, previously available only for borders, to basins and furrows; and offers user-selectable color schemes to display contours.
•
Simulation incorporates the latest SRFR simulation engine; corrects several computational problems noted in the legacy SRFR engine; improves the implementation of furrow infiltration calculations with the NRCS method; replaces two of the wetted perimeter options available for calculation of furrow infiltration (upstream wetted perimeter and upstream wetted perimeter at normal depth) with a single option (this new option, representative upstream wetted perimeter, can be used under any slope condition); and limits the combinations of infiltration function and wetted perimeter calculations options that the user can select when calculating furrow infiltration.
An upgraded manual is still under development, and plans are to complete the manual by the spring of 2008. In the meantime, your technical inquiries can be directed to Eduardo Bautista at [email protected].
WinSRFR 2.1 was developed and tested extensively in a Windows XP environment and has been subjected to limited testing under Windows Vista. If anybody experiences any installation or possible operating system-related problems, please direct your comments to Jim Schlegel at [email protected].
