With Africa's water assets continually threatened through an expanding inhabitants and the ensuing upward thrust in water call for, including the stresses of water use for numerous actions, desertification, weather switch, and different interventions within the water cycle by way of guy, it will be important that the water assets in arid and semi-arid areas are built and controlled in a sustainable and built-in demeanour. In Water assets of Arid parts, those key elements are explored and tested by way of major specialists, concentrating particularly upon the query of groundwater recharge and dividing dialogue into the next sections: ordinary and synthetic groundwater recharge; socio-economic facets of water call for administration; geophysical, GIS and distant sensing recommendations for groundwater exploration; weather switch and its effect on water assets; vulnerability and chance evaluation; and water administration. Comprising the complaints of the foreign convention on Water assets of Arid and Semi-Arid areas of Africa held in Gaborone, Botswana, August 3-6, 2004, it is a very important textual content for researchers and practitioners within the fields of floor water hydrology, groundwater hydrology, environmental engineering, agricultural engineering and earth sciences, in addition to for these occupied with water assets making plans, improvement and administration in arid and semi-arid components.

Mathematically entropy of a system {xi} is defined in its discrete form by the following expression (1) where K: is a function of the base used or the scale factor (bits for base 2, napiers for base e, decibels for base 10), i=1, 2,…, n and pi is the probability of occurrence of the event i. It can be shown that the value of H(X) reaches its maximum when all variate values xi are equally likely, that is, when the outcome has maximum uncertainty (Amorocho & Espildora, 1973). In this case the entropy becomes Hmax (X)=log n (2) The theoretic entropy definition was extended to hydrology.
