Types of Embankment Dams - Earth Dams, Rockfill Dams

The two principal types of embankment dams are earth and rock-fill dams, depending on the predominant fill material used. Some generalized sections of earth dams showing typical zoning for different types and quantities of fill materials and various methods for controlling seepage are presented in Figure 2-1.

Impact of Small Hydropower Projects

Renewable energy can make a significant contribution to carbon dioxide (CO2) emissions reduction. It should be accepted that although through having no emissions of CO2 and other pollutants, electricity production in small hydro plants is environmentally rewarding, the fact is that due to their location in sensitive areas, local impacts are not always negligible.

How to Build Small Dams - Design and Construction

Dams built up on small scale by compacting successive layers of earth, using the most impervious materials to form a core and placing more permeable substances on the upstream and downstream sides. A facing of crushed stone prevents erosion by wind or rain, and a suitable spillway, usually of concrete, protects against catastrophic overflow of the dam. Small

Classification and Types of Dams based on different Criteria

Types of dams on the basis of materials used in dam construction Rigid Dams (Concrete dams, steel dams, timber dams etc) Non-Rigid dams (Beam Design Formulas , rockfill dams)

Causes of Dam Failure

At least 20% of the world ’s more than 9 000 fresh water fish species have become extinct, threatened or endangered in recent years. The watersheds of the world are the habitat of 40% of the world’s fish species, and provide many ecosystem functions ranging from nutrient recycling and water purification to soil replenishment and flood control.
