CLIMATE VARIABILITY AND EXTREME EVENTS ANALYSIS IN THE ZAMBEZI RIVER BASIN USING STANDARDIZED PRECIPITATION EVAPORATION INDEX AND L-MOMENTS

admin 14 June 2019
Body

The Zambezi River is a very important water resources with its catchment area covering most parts of Southern Africa. It is a habitat to a wide range of plant and animal species. Humanity in
this region just like other animals depend on water from the Zambezi River and its tributaries. Its dependence ranges from provision of potable water, agriculture, power, manufacturing, mining, tourism and many other sectors (World Bank 2010). With such benefits from the river, the human population is proved to be rapidly increasing. For example, an annual increase of 3.9% in Africa (the highest in the world) has been recorded with most of the increase in the Southern part of the continent, which is mostly covered by this basin (World Bank, 2010). Despite the population boom, industrialization and urbanization, not all Africans have access to clean water and sanitation. Water availability varies from country to country as some parts of Southern
Africa receive very low mean annual rainfall (Namib and Kalahari deserts) and low river flows with others receiving very high precipitation (areas in the sub tropics) hence high river flows.
With this in mind, more water is needed to meet the increasing demands in clean water, sanitation, irrigation, power (Hydroelectric) and many for factors increasing the demand (O Serdeczny et al.,2016).

60 ans de pluies mensuelles en Afrique - Période 1940-1999

60 ans de pluies mensuelles en Afrique
Période 1940-1999

 

HydroSciences Montpellier a hérité du laboratoire d’hydrologie de l’IRD, d’une très importante base de données hydroclimatiques sur l’Afrique de l’Ouest et Centrale. Différents programmes de recherche ont permis aux hydrologues d’HSM d’enrichir cette base sur la période post 1980 et sur la totalité du continent africain.

Un long travail de critique a permis de constituer une base de données de référence des pluies d’Afrique au pas de temps mensuel.

En raison de données trop rares et trop hétérogènes sur le début du XXème siècle, les grilles ont été calculées de 1940 à 1999 (720 mois).

Nous proposons ci-dessous en téléchargement gratuit les grilles (un fichier par décennie, 120 grilles par fichier) calculées à partir des données observées aux stations. La méthode est l’Inverse Distance Pondérée, le pas de temps est mensuel et l’échelle spatiale est le demi-degré carré.

Un fichier .pdf à l’intérieur de chaque fichier .zip détaille le mode opératoire de la confection des grilles et la description du fichier.
