An automated computer program isdeveloped for calculating areal average rainfall(AAR) value and its implementation is presentedfor the arid region representative country,Libya.The procedure is conceptually simple byconsideration of almost equilateral trianglesconnecting adjacent meteorological...

Depiction of precipitation change by elevation in an areaindicates the possibilities of orographic rainfall occurrencesin the mountainous regions. In general, precipitation increaseswith elevation but sometimes inverse cases occur locally due toorographic and meteorological features of the area....

Wadis are arid region drainage basins, mostly in the Quaternary depositions of different facies and grain size distributions depending on the paleogeologic environmental processes. Random and heterogeneous setup of the subsurface geological layer composition gives rather independent, haphazard...
