- ... Following a major expansion of the hydrometric network in the 1960s, flow gauging operations in Lebanon were curtailed from 1975 to 1990 due to the civil war and only a partial service has resumed since then. The implications of these limitations on flow data availability are examined from the standpoint of estimating the overall surface water resources of Lebanon and for developing regional estim ...

- ... Soil erosion on agricultural land has become a global environmental problem and information on rates of soil loss is an important requirement both for quantifying the problem and for developing improved land management and soil conservation practices. The use of fallout 137Cs measurements overcomes many of the difficulties facing traditional approaches to erosion monitoring and affords an effectiv ...
