2011/3/14
This paper describes the evaluation of the KNMI Cloud Physical Properties – Precipitation Properties (CPP-PP) algorithm over West Africa. The algorithm combines condensed water path (CWP), cloud phase...
A comparison of ASCAT and modelled soil moisture over South Africa，using TOPKAPI in land surface mode
ASCAT modelled soil moisture South Africa TOPKAPI land surface mode
2010/4/7
In this paper we compare two independent soil moisture estimates over South Africa. The first estimate is a Soil Saturation Index (SSI) provided by automated real-time computations of the TOPKAPI hydr...
A geographic information systems analysis of hydro power potential in South Africa

Electrification can reduce the dependence on combustible fuels and therefore also reduce the concomitant health risks. Hydro power is one possible method of generating electric power close to the pote...
Physically-based modelling of hydrological processes in a tropical headwater catchment (West Africa) – process representation and multi-criteria validation
soil moisture West Africa tropical headwater catchment
2009/5/15
The aim of the study was to test the applicability of a physically-based model to simulate the hydrological processes in a headwater catchment in Benin. Field investigations in the catchment have sho...
Comparison of soil moisture fields estimated by catchment modelling and remote sensing：a case study in South Africa
soil moisture catchment modelling remote sensing
2009/5/4
The paper compares two independent approaches to estimate soil moisture at the regional scale over a 4625 km2 catchment (Liebenbergsvlei, South Africa). The first estimate is derived from a physically...
Relationships between the El-Niño Southern Oscillation and spate flows in southern Africa and Australia
arid zones streamflow spates climate variability ENSO
2009/3/11
The flow records of arid zone rivers are characterised by a high degree of seasonal variability, being dominated by long periods of very low or zero flow. Discrete flow events in these rivers are infl...
