The main building of the irrigation system can be defined as a complex of buildings that are planned along the river or stream to divert water into a network of channels that can be used for irrigation purposes.<\/span> The main building can reduce excessive sediment load, and measure the amount of incoming water.<\/span> The main building consists of a weir with energy absorbers, one or two major decision, flush doors, megrim pool, and a bag of mud, flood dikes and building complementary.<\/span><\/p>\n

a.<\/strong><\/span> Weir<\/strong><\/span>
\n Weir on the surface irrigation systems can be divided into two types, namely weir (weir) and motion weir (barrage).<\/span> Weir is used to raise the water level in the river up to a certain height necessary for water to be flowed into the irrigation channel and tertiary.<\/span> It will determine the height of the area irrigated.<\/span> Dam building bending motion is equipped with a door that can be opened to drain the water at the time of the great flood and closed when a small stream.<\/span><\/p>\n

In Indonesia, dam building motion is most commonly used to divert river water for irrigation purposes.<\/span>

b.<\/strong><\/span> Rubber weir<\/strong><\/span>
\n<\/strong> Rubber dam has two main parts, namely the body is made of a rubber dam and a concrete foundation slab concrete shaped as a rubber tube holder and a control room equipped with several equipment (machines) for controlling expand and collapse of the rubber tube.<\/span> Weir serves elevate the water level by developing the dam body and lowering the water level by means of deflating the weir body is made of a rubber tube can be filled with air or water.<\/span><\/p>\n

The process of filling air or water from the air or water pump is equipped with air or water control instruments (manometer).<\/span>

c.<\/strong><\/span> Decision-free<\/strong><\/span>
\n Free retrieval is building created by the river that drains into the river water irrigation, without set the water level in the river.<\/span> In such circumstances, it is clear that the water level in the river should be higher than the irrigated area and the amount of water that must be guaranteed sufficient deflected.<\/span><\/p>\n

d.<\/strong><\/span> Decision of the Reservoir<\/strong><\/span>
\n<\/strong> Reservoir (reservoir) is used to store irrigation water in times of excess water in the river that can be used any time there is a shortage of water.<\/span> Thus, the primary function of the reservoir is to regulate the flow of the river.<\/span> Large reservoirs often have multiple functions such as for irrigation, hydroelectric power generation, flood control, fisheries and others.<\/span> Smaller reservoirs used for irrigation purposes only.<\/span><\/p>\n

e.<\/strong><\/span> Pumping stations<\/strong><\/span>
\n lrigasi to be considered when making the pump by gravity was not feasible in terms of technical and economical.<\/span> In the beginning of irrigation pumps require only little capital, but the cost of exploitation is expensive.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
