Description:
The recharge processes have been evaluated for two karst massifs of southern Italy, the Mt. Terminio and Mt. Cervialto, characterized by wide endorheic areas. The annual means recharge has been estimated by GIS tools, from regression of annual mean values of different ground-elevated rain gauges and thermometers. The recharge has been distinguished for endorheic areas and the other areas of springs catchment, and the ratio between the output spring and input rainfall has been also estimated (recharge coefficient). The annual recharge has been used to calibrate a daily scale model, which allows to estimate the amount of effective rainfall which is retained as soil moisture, the amount reaching the water table (recharge s.s.), and the amount of rainfall which develops the runoff. All this amounts vary through the hydrological year, in function of soil moisture deficit and daily rainfall intensity. The model allows estimating the recharge conditions through the hydrological year, and it is a useful tool for water management. This article is protected by copyright. All rights reserved.
