Abstract

In the agriculture sector, combining physically based soil water balance and simulation models with GIS tools is of a considerable interest to manage the available water amount. Indeed, this combination can enhance water supply management, optimize agricultural catchments management and study impact of management intervention from small scale (plot) to a larger one, such as irrigated district and/or region.
This work presents the case of Nebhana Dam System in the region of Kairoun (central Tunisia). The main objectives were to: (1) create a specific GIS database for the six irrigated districts of the area Ain Boumorra 1, 2 & 3, Fadhloun, Dar Jameya and Sisseb 1 based on the characteristics of cultivated crops, soils types and used irrigation systems; (2) assess spatial and temporal variation of soil water budget terms from plot and farm levels to irrigated district and regional scales; (3) map results for different time steps.
The achievement of these objectives was made possible using the WEAP-MABIA Model. Thus, daily Penman–Monteith reference evapotranspiration (ETo), effective precipitation (PE), crop water requirement (CWR) and irrigation water requirement (IWR) were estimated for the six irrigated districts and their related farms and plot using spatially distributed parameters on climate, crop, soil characteristics, irrigation system and basic irrigation management practice during the cropping season 2014/2015.
