Water Resources

Water Resources

Water resources are sources of water that are useful or potentially useful. Uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water.97% of the water on the Earth is salt water. However, only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air.
The total quantity of water available at any given time is an important consideration. Some human water users have an intermittent need for water. For example, many farms require large quantities of water in the spring, and no water at all in the winter. To supply such a farm with water, a surface water system may require a large storage capacity to collect water throughout the year and release it in a short period of time. Other users have a continuous need for water, such as a power plant that requires water for cooling. To supply such a power plant with water, a surface water system only needs enough storage capacity to fill in when average stream flow is below the power plant's need. Nevertheless, over the long term the average rate of precipitation within a watershed is the upper bound for average consumption of natural surface water from that watershed. Natural surface water can be augmented by importing surface water from another watershed through a canal or pipeline. It can also be artificially augmented from any of the other sources; however in practice the quantities are negligible. Humans can also cause surface water to be "lost" (i.e. become unusable) through pollution.
This section is to address real challenges faced by the water community and provide a platform for the development and appropriate application of water technology; water quality analysis and advancement. The expert team involved has provided technical support to many government agencies, municipalities and private sector end-users in the water sector. The highlighted projects organized by them: Ground Water, Wastewater, Watersheds and Geo-Environmental. The current Water resource Studies team engages expert members from across country and retains a core staff of personnel that enables professional project deployment and management. Tarhafra provide quality hydrogeological and water resource services to clients in the industrial, mining, energy, municipal, land development, tribal, and agricultural sectors. We combine our unparalleled groundwater hydrology experience with expertise in water resource policy and economics to develop comprehensive approaches and integrated solutions.
