Write a report assessing the feasibility of different techniques for providing fresh water to arid regions of the world - Essay Example The essence of any system is to maximize on the output and reduce the amount resources gathered to enhance the system. The easy will focus on details of different sources of water collections and recommend on an effective plan to utilize in the Nubian Desert. The focus will be on Nubian Desert. Covering an Area of more than 400,000 Square kilometres, the region remains venerable to water shortage. The arid region is bordered by the large Sahara desert. It has a minimal rainfall of 125mm per year. The desert is located in Sudan North-East part of Africa (world atlas, n.d ). In this model, underground water reserves are exploited and utilized in various ways. The common method of harvesting underground water is through boreholes. Different sites are set and underground water utilized for both domestic and agricultural purposes. The technique requires technical knowhow at the initial stages. This means locating sites to be drilled. After a site is located, the drilling process begins. During this process, both mechanical and human power is required. Limits spaces are need as the size of a borehole is smaller compared to other forms of water harvesting. The availability of this resource will determine the life of the borehole (Thangarajan et al, 2002). Some arid areas experience limited amounts of rainfall per year. With the right mechanism, the water could be collected and used for both agricultural and domestic purposes. In analyzing this aspect, hill slope dams are required. Rainwater is collected down rock hill slopes. Gravity is what is needed to collect water and be pumped into storage tanks. The technique requires a large surface area as water from the hill tops need to be collected over a wider area compared to borehole drilling where a small excavation of the earth is done. The hill slopes dam could only be effective in regions with limited amount of rainfall. In most arid areas, they hardly
