Canal Lining & Irrigation Irrigation is the artificial application of water to the land or soil. It is used to assist the growing of agricultural crops, maintenance of landscapes, revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Irrigation systems are also used for dust suppression, disposal of sewage and in mining. Irrigation is often studied together with drainage, that is the natural or artificial removal of surface and sub-surface water from a given area. Lining is a resistant layer made of concrete, protecting the canal bed and its sides in order to have a sufficient strength to resist water pressure. The layer advantage is to save water for extension of irrigation, to minimize filtration losses, improve duty, minimize maintenance cost and to prevent growth of wild plants.
Water Management Water is an essential resource for all life on the planet. Water resource management planning has to take account of all the competing demands of water by mankind (sanitation, drinking, manufacturing, leisure and agriculture.. ) and seeks to allocate water on an equitable basis to satisfy all uses and demands. For this specific case, concrete has a great application in water resource management in activities such as planning, developing, distributing and managing the optimum use and treatment of water resources.
