Rainfall should sustain the increasing needs

of agricultural irrigation, the growing population,

and rapid industrialisation (Singh

et al., 2002). Water scarcity, however, is a

chronic problem in the arid and semi-arid

countries of the Middle East. The Kingdom

of Saudi Arabia (KSA) has an extremely dry

climate with a large water supply deficit. The

spatial and temporal distribution, quantity,

and duration of rainfall in the arid and semiarid

zones of the country are highly variable

(Noy-Meir, 1973; Subyani, 2004; Kwarteng

et al., 2009; El-Nesr et al., 2010).

Rainfall is a main source of water in the

KSA. The disparity in rainfall distribution is

great, and some parts of the country receive

heavy rainfall, while others receive little.

Thus, this study was conducted to analyse

the statistical and spatial distribution of

rainfall in the KSA over a 30-yr period.
