A Critical Study of Water Loss in Canals and its Reduction Measures

Water is a very precious natural resource. When this precious resource moves through the canals certain part of the water is lost by seepage, evaporation etc. This loss is known as conveyance loss. The conveyance loss was calculated experimentally by different researcher on different canals around the world. In this paper author have tried to review some of the research work and recommend an average water loss from the canal irrespective of the soil and other environmental condition. There are different materials which have been used in canal lining to reduce this water loss. No such material can be said it is the best material for reducing water loss because it depends on the site and its environmental condition. Now a days geosynthetic alone or geosynthetic with concrete or precast concrete is used to for canal lining in this paper they have tried to see the strength, durability etc. of different geosynthetic material and its application in canal lining.
