An empirical model for the evaluation of the degree of saturation of shallow soils in relation to rainfalls

摘要: The evaluation of shallow soils water content is very important in many fields, and different hydrological models are widely applied to simulate field-scale flow soil content. degree saturation a time-varying variable, depending on weather conditions. In applications, it useful directly correlate the time series rainfall amount. This paper presents simplified empirical model, which allows for computation using readily available climate data air temperature depths. model tested with situ measurements collected at three sites Emilia Romagna region northern Italy. experimental compared results obtained from over an observation period almost 5 years. has been used generate depths requires separate calibration each depth where computed. A discussion model's also carried out clarify sensitivity parameters choice input data.
