Subject: Video Demonstration of the new daily FAO 56 hydrology method in WEAP   
Posted: 2/18/2011 Viewed: 12467 times
I have created a 13-minute video demonstration of the new "MABIA" method for catchment hydrology in WEAP. This video, and the earlier one on WEAP's new Scenario Explorer, can be found here:

The MABIA method is a daily simulation of transpiration, evaporation, irrigation requirements and scheduling, crop growth and yields, and includes modules for estimating reference evapotranspiration and soil water capacity. The MABIA Method uses the dual Kc method, as described in FAO Irrigation and Drainage Paper No. 56, whereby the Kc value is divided into a basal crop coefficient, Kcb, and a separate component, Ke, representing evaporation from the soil surface. The basal crop coefficient represents actual ET conditions when the soil surface is dry but sufficient root zone moisture is present to support full transpiration. It was derived from the MABIA suite of software tools, developed at the Institut National Agronomique de Tunisie (INAT) by Dr. Ali Sahli and Mohamed Jabloun
