obtain such embankment materials. If a variety of soils are readily available, a zoned embankment will usually be chosen because it is generally superior for both stability and seepage performance. Zoned dams (as discussed later) also afford better ability to use material in the embankment section from required excavation.

allel to the axis of the dam, and filled with clay puddle to form a water-tight connection with the rock, and prevent the water in the reservoir from' passing through the porous materials under the body of the embankment. This interesting dam will be more fully described later, when the different types of earth dams are dis-.
Dams and its types. A dam is a hydraulic structure of fairly impervious material built across a river to create a reservoir on its upstream side for impounding water . behavior of an earth dam is entirely different from that of a gravity dam. The earth dams are usually built in wide valleys having flat slopes at flanks (abutments).
