CRITERIA FOR DESIGN OF EARTH DAMS
The criteria for the design of earth dams are: 1. Sufficient spillway capacity and freeboard are provided so that there is no danger of overtopping of the dam 2. Seepage flow through the embankment is controlled so that the amount ...
Types of Earthfill Dams – Applications and Advantages
Earthfill dams are the most common type of dam built to any height. They are designed as a non-overflow section with separate spillway. The reason for such wide spread use of earthfill dams are: The foundation requirements are not as ...

Factors Affecting Velocity Distribution in Open Channels
In an open channel flow, velocity distribution is non-uniform which means velocity is different at different depths. Various Factors such as channel slope, alignment, shape, roughness etc plays key role in velocity distribution. Velocity Distribution in Open Channels An open ...
Forces Acting on a Dam Structure and Calculations
Different types of forces acts on a dam structure such as water pressure, self weight, wave pressure etc. Determination of various forces which acts on the structure is the first step in the design of dams. These forces are considered ...
