The artificial lakes are not only created for generation of current. They serve also for the irrigation of agrarian areas, water supply of humans and animal, for catching the flood likewise, for the raising of fish and aquatic plants and as recreation area or water port centers.
The different forms of the dams become not simple by the architect but by the valley form, which area condition determines and from the available building materials. The elbow rope wall transfers the strength of the water owing to the curved wall to the valley. The weight rope wall holds back the water by its weight. The elbow gravity dam is a mixture from the two already introduced concrete dams. With its weight and by supporting the strength of the accumulated water on the valley, it can hold back the water. The arrow rope wall is simply a concrete wall, which is supported with columns. In order to save building material, cavities exist between the columns, which derive the pressure of the water into the soil. The dam is very much broader in the cross section than high. The inside consists of a close core, which is supported both sides by ground connection or rock material. Before man begins with the expensive buildings of a dam, he must meet exact clarifications: The requirement of electricity and water must be plumbed. Additionally the cost/use relation is determined exactly. It is clear that also natural prerequisites for the building of a dam must exist: |

Topography: The area should not be "disfigured" by the dam.
Water regime: The rain and discharge quantities in the catchment area of the artificial lake give information over it on how much water we can count within a certain period. Geology: Is the basin of the lake how load-carrying and permeable? The architect has to clarify this question to know whether the water would seep in certain places and whether larger landslides are to be feared. Ecology: The consequences of a dam construction on the environment are considered always in detail. Economics: The people always consider, how they earns with few water the most cash. |
