This paper is aimed at developing a geostatistical model to improve interpolated annual and monthly rainfall variation using remotely-sensed cold cloud duration (CCD) data as a background image. The data set consists of rainfall data from a network o

The agricultural economic sector of Botswana is limited mainly to range resources-based livestock and pockets of arable farming based on rainfall and limited irrigated agriculture at several places. In this study agricultural sustainability of rain-f

Botswana is a semi-arid country with limited recharge to groundwater resources. Groundwater however is a major source of water for domestic, industrial and agricultural uses. There is therefore the need to ensure that the groundwater resources are of

In the Moshupa Wellfield area of Botswana, fractured and weathered parts of the basement granitic rocks constitute the dominant local aquifers. Investigation of these aquifers was achieved using 2-D electrical resistivity imaging. The 2-D continuous

A distributed GIS-based hydrological model is developed using GIS and computational hydrology techniques. The model is based on water balance consideration of the surface and subsurface processes. The surface water balance processes include precipita

Design of drainage and dam structures involves a full understanding of the duration, magnitude and volume of peak flood flows anticipated. For gauged catchments a number of established flood frequency models and rainfall-runoff models are used widely

A parametric precipitation model is developed for generation of daily rainfall time series based on historic data. The precipitation model is a composite model of Markov-chain (MC) and probability distribution (PD). Thirty nine rain gauge stations in

In an attempt to investigate possible trend in the annual river runoff of 502 rivers in the region of southern Africa, possible trends were first visualized and examined by the use of rescaled adjusted partial sums (RAPS) rather than the actual time
