Case Study Of "Neera Devdhar" Canal Seepage Losses and Canal Lining
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
In india canal irrigation is a major source of artificial irrigation. Many canals are unlined and due to that major seepage is found in unlined canal.50 to 60 % seepage is found in unlined canal. Concrete, shortcrete, stones are the general materials used for lining of canal. Concrete can reduce seepage losses upto 70 % as well as shortcrete is efficiently reduce losses upto 90 %.these materials also required a maintenance due to expansion and contraction cracks. Hdpe sheets is the best solution to reduce the seepage losses from concrete lining cracks. Indian government also provides a subsidy for using this sheets as a lining material. Concrete and shortcrete can be used as covering and protection material to hdpe from external agencies like damage from stone and crawling animals. Kolhapur’s dudhganga canal is best example of (hdpe + concrete) lining canal. We can save 100 % water by using this materials combination and more area will be comes under irrigation. We can also provide a sensor system on canal to find out canal discharge and water level in canal at different sections in canal. Radar, bubbler are the best sensor system to find out the discharge at different sections of canal. So we can easily locate seepage at any section. With the help of hdpe sheets and sensor system we can reduce the seepage losses in canal upto 100% and achieves more benefits by reducing water losses and more cultivation of crops
