背景

Watershed Monitoring and Modelling: Remote Sensing and GIS Applications in the Mediterranean Environcumulation in reservoirs suggest soil loss rates of 7.4 and 4.7 t/ha/yr. However, the SEMMED-estimated values were 3.56 and 2.78 t/ha/yr. - a major underestimation. There is a need for more detailed soil data and a re-examination of vegetation cover inputs.

There is concern that resources are being wasted by the current subjective expert-assessment approach to hazard definition and by the systematic over-design of protection measures.
