The book is an ambitious attempt to summarise the topography, climate, surface hydrology and groundwater of the whole Arab region. It assembles a lot of material which is readily available only in consultants' reports and similar sources. There are a number of statistical tables covering these topics.
The book contains twelve chapters and three appendices. These chapters comprise a historical introduction, physiographic features and geological settings of the region, climate, analysis of precipitation, evaporation and evapotranspiration, river basins and flow, wadi basins and flow, erosion and sedimentation, groundwater resources, non-conventional water resources, storage of water and impacts of the water scarcity on the future of the region. Appendices I, II and III, on a CD-ROM at the end of the book, list meteorlogical data, hydrologic data and water quality data used in preparing the book.
