Assessment of Silyaninov index for detecting climatic changes and droughts in the central Sudan

Drought is a constraint upon development in Sudan. This paper attempts to understand drought and climate change in the central Sudan using the Silyaninov index (SI) because of its simplicity and its required datasets (monthly rainfall and temperature) are routinely collected in developing countries. Also, the ecoclimatological relationships for the natural vegetation cover were investigated using the normalized...

Groundwater resources of the Niger Delta: Quality implications and management considerations

The Niger Delta region of Nigeria is of great socio-economic importance because of its huge and abundant reserves of crude oil and natural gas. The phenomenal increase in both industrial and social activities within the area in recent times has led to increase in groundwater abstraction rates. Groundwater development in the Niger Delta region has been carried out with little hydrogeological considerations. This is...

Estimation and mapping of groundwater characteristics in Greater Wad-Medani Locality, Gezira State, Sudan

Groundwater dominates the domestic water supply (85%) in the Gezira State, Central Sudan. Groundwater resources in Gezira are basically represented by two water-bearing geological formations: the Nubian Sandstone formation overlain by the Gezira formation and shallow quaternary to recent deposits in minor streams. This study aims at identifying the pattern distribution of selected aquifer characteristics of the Gezira...
