Development and evaluation of the Water Resources in Tendelti City

Abstract

This study is done to evaluate the groundwater resources in north lfordofan state between longitude 29° 30’to 32° so’E and latitude 12°00 to 13° 4o'N. The purpose of the study is to investigate and evaluate the groundwater in the Tendelti drainage basin. The geological units Rocks in the study area are; the basement -— complex, sedimentary it's about 1000 lfm length and covers an area of approximately 6000 Km’ includes: Nubian sandstone, llmm lluwaba Formations and superficial deposits (clayey plains and sand dunes). For remote sensing studies the Land - sat Thematic Mapper (Tlll) is used to hydrogeological map preparations. lt is evident that these integrated study techniques are useful reconnaissance method for water resources studies. The hydrogeological setting can he identified by two aquifer types: The shallow aquifer, include the upper llmm Ruwaba aquifer, Wadies, and sand dunes aquifers. This group is considered as perched water. The depth to the water level ranges between 2 meters to 30 meters from the surface land. The other group — is the Deep Umm Ruwaba aquifer which is the main aquifer in the area The water table of deep aquifer ranges from 71 meters to 87 meters from the subsurface land. The chemical analysis of water samples was performed to determine the suitability of groundwater for human consumption and agricultural purposes according to (WHO) standards. According to The total Dissolved Solid (TDS) values which are determined by chemical analysis (Titration), water resources can be classified in to two types. One of each is fresh water used as drinking water) and type of another is brackish water which used for agricultural purposes)
