Design of Headwork for Lower Nagavali Irrigation Project

Pangeni, Balkrishna (2013) Design of Headwork for Lower Nagavali Irrigation Project. BTech thesis.



ABSTRACT This paper discuss about the design methodology of a dam and its stability against failure for a Irrigation project. Most of the people of Rayagada district has taken agriculture as their means of living and they are mostly dependent on seasonal rainfall for cultivation. This dependeny on direct rainfall water for the cultivation of crop has lead to the reduction in crop yield due to lack of rainfall.So, in this paper, I have studied the hydrological feature of the area,analysed it and a suitable section is designed considering the design flood and the discharge that can be made avaialabe at the downstream.The dam is then analysed using a software, PLAXIS for its stability and suitability.Finally, a complete profile of a ogee crested spillway is drawn.Successfull implementation of this project will facilate irrigation water for Gross Command Area(GCA) of 14,000Ha and Cultivable Command Area(CCA) of 8,500 Ha.
