• The control of salinization in a system with irrigation, drainage and interaction with an aquifer system is a complex operation, in which models can be useful. One such model is the regional hydrological model SIMGRO, which simulates the water flow in the saturated zone, in the unsaturated zones and in the surface water in an integrated manner. It can take into account the effects of irrigation, drainage, groundwater use and their impact on the evapotranspiration of different crops (Querner et al., 1997). Recently, the model has been extended with the transport of a conservative matter, making it possible to estimate salinity levels in terms of electrical conductivity (EC). This paper describes the modified SIMGRO hydrological model and its usefulness in evaluating measures to control salinity. The model was applied in the Pescara area, situated in the Mendoza river basin, where water from the river and effluent water from factories is used for irrigation. Salinity has become a serious problem in the area as a result of natural processes and the discharge of saline water by the factories.We describe how we calibrated the model and then performed runs with several scenarios, to evaluate the efficiency of certain measures for reducing salinity.

Abstract

• In irrigated areas with drainage and an important interaction with the groundwater system, it is often difficult to predict effects of measures to control salinity. Therefore, in order to evaluate measures to control salinity the SIMGRO integrated regional hydrological model was extended with a module for conservative matter. This modified model was applied to an irrigated area of 2650 ha in the province of Mendoza, Argentina, after being calibrated with data on groundwater levels, evapotranspiration and salinity. The differences between calculated and observed salinity were generally small, except in the root zone, where observed values varied considerably in time and over short distances. Runs with four scenarios revealed that using more groundwater would be a very effective measure for controlling salinity. In subregions with shallow groundwater, improving the drainage systemwould also be beneficial and has the advantage that there is no risk of overexploiting the aquifers, which are a finite source of good quality water.
