Study of water stress and droughts with indicators using daily data on the Bani river (Niger basin, Mali)

چکیده
As in most part of Africa, the Bani basin (Niger River, Mali) is threatened by climate changes. This study focuses on droughts hazard and its indicators as derived from the Climatic Moisture Index using the monthly data for the period (1963-2000), in order to examine the Bani basin vulnerability to water stress. In this study, water deficit (drought) was logically addressed using the Standardized Precipitation Index at a 10 days time step. The inadequacies in the Standardized Precipitation Index while estimating water deficit within the basin based on technical issues result in the usage of the Effective Drought Index (EDI). This robust index is 1 Corresponding author E-mail: [email protected] Tel : +33 143 94 73 67 ha l-0 05 66 01 4, v er si on 1 15 F eb 2 01 1 Author manuscript, published in "International Journal of Climatology 30 (2010) 1689–1705" DOI : 10.1002/joc.2013

According to recent Studies, about 60 percent of surface waters and 57 Percent ground waters are located in snowy zones in Iran. In most areas of northern hemisphere and alpine environment areas, snow melt lead to the maximum instantaneous flow rate and is an important part of annual discharge. The present study investigated the effect of snowmelt on the surface waters and ground waters in B...
متن کاملIntegrated Planning of Water Resources Based on Sustainability Indices, a Case Study: Hamoon- Jazmorian Basin
Nowadays, the water supply and water demand management are the main issues in water resources planning. It is more important in a river basin with a complex system facing with droughts, climate changes, inter-basin water transfer and operational and under study dams. In this paper, for water resources planning in a river basin and reducing the difference between water resources and water demand...
