Impact and adoption of SWC techniques: research progress and preliminary results

Abstract

The main objective of this research is to model the impact of soil and water conservation (SWC) structures on runoff and erosion processes at the watershed scale, by means of watershed-based modelling (SWAT software). Modelling is performed in selected watersheds for which good calibration and validation data are available. Selected watersheds are located in different regions of northern, central and southern Tunisia. The activity largely builds on existing databases and on a limited amount of high quality data purposely collected in the field. The main example of this is the monitoring equipment installed to measure the water level changes of a hill lake located in the Zoghmar site (Sidi Bouzid), and the bathymetric surveys previously performed in the same lake.
