Types of Dams:   Dams can be grouped according to the type of material of which they are constructed as follows; concrete dams are further grouped according to how they achieve their strength and stability.  CONCRETE DAMS Concrete Gravity Dams Concrete Arch Dams Concrete Buttress Dams FILL (EMBANKMENT) DAMS Earth Dams Earth and Rock Fill Dams Concrete Faced Rock Fill Dams Concrete Gravity Dams rely on the weight of the concrete of which they are built to resist the forces (gravity, water pressure, earthquake) to which they are subjected. Concrete Arch Dams and Buttress Dams can be built using a smaller amount of concrete than that required for a Gravity Dam and, as a result, are cheaper to build. This is possible because Arch and Buttress Dams are designed to transfer some of the loads (forces) on them to the foundation on which they are built ie the strength of the foundation is used to help resist the loads which could not be resisted simply by ...

  dam  is a barrier that impound water  or underground streams. Dams generally serve the primary purpose of retaining water, while other structures such as f loodgates  or levees  (also known as  d ikes ) are used to manage or prevent water flow into specific land regions.Hydropower  and  p umped storage  electricity   are often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations.

Sprinkler Irrigation is a method of applying irrigation water which is similar to rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air and irrigated entire soil surface through spray heads so that it breaks up into small water drops which fall to the ground . Sprinklers provide efficient coverage for small to large areas and are suitable for use on all types of properties. It is also adaptable to nearly all irrigable soils since sprinklers are available in a wide range of discharge capacity.
