Different Types of Buttress Dams -Their Functions and Applications
A buttress dam is a modification of gravity dam by constructing solid walls parallel to the water flow. Types, functions and applications of buttress dams are discussed.
Types of Cofferdams and Their Construction Details
There are various types of cofferdams used for construction of structures in water. Construction details of these cofferdams are provided in this article.
Failure of Gravity Dams – Causes and its Failure Modes
Failure of gravity dam occurs due to overturning, sliding, tension and compression. A gravity dam is designed in such a way that it resists all external forces acting on the dam like water pressure, wind pressure, wave pressure, ice pressure, ...
DESIGN PRINCIPLES OF EARTH DAMS
Design of earth dams starts with calculation of forces acting on the dam structure. The loads acting on earth dams is same as loads acting on gravity dams. Earth dams are made of non-rigid materials i.e. soil. Fig: Earth Dam ...

STRUCTURE (PARTS) OF A GRAVITY DAM Heel: contact with the ground on the upstream side Toe: contact on the downstream side Abutment: Sides of the valley on which the structure of the dam rest Galleries: small rooms like structure left ...
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 ...
