Vertical drop weir is such a weir, whose D/S face is given steep batter. The U/S face is mostly vertical, but it can also be given batter like D/S face. The design of such a weir consists of: 1. Fixing Various Elevations by Hydraulic Computations 2. Design of Weir Wall 3. Design of Impervious Floor of the Weir Wall 4. [...]
The following are the various methods which can be adopted for carrying out the stability analysis of gravity dams: 1. Gravity Method: This method of stability analysis is also sometimes known as two dimensional methods. In this method, the dam is considered to be composed of parallel sided vertical cantilevers. Each cantilever is considered free to act without any attachment [...]
A detailed sketch of a gravity dam is shown in Fig. 13.1. All the predominant forces that act on the dam have been shown in the figure itself. The forces that act on the dam are the following: 1. Weight of the dam 2. Horizontal hydrostatic pressure due to water 3. Uplift pressure due to water percolated under the dam [...]
