Abstract
Groundwater recharge is one of the key factor of the hydrological budget. Many methods could be used to have reasonable estimates of this parameter like the water-balance method, the water table fluctuation method or via numerical simulations (NIMMO et alii, 2005). Usually these methods are valid for watershed studies but need to be validated for site specific applications. Tracer techniques for recharge assessment are often time consuming and their laboratory costs are quite elevated. A relatively cheap solution is to employ low cost TDR probes to monitor the water content and the soil electrical conductivity (NOBORIO et alii, 2001; MORTL et alii, 2011). The aim of this study is to evaluate the limitation of continuous monitoring in determining groundwater recharge rates in agricultural silty soils.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
