Lowering target

from Wikipedia, the free encyclopedia

The lowering target is the water level of a dam or a dam at the level of the operating outlet, i.e. the lowest water level intended for normal operation. In some systems there is also the lowest lowering target below the lowering target , between which there is the reserve room , the water volume of which is only intended for exceptional cases such as extreme drought. The reserve space can be emptied via the bottom outlet , with which the reservoir can be completely emptied. Only in rare cases is there any water left that cannot drain due to the terrain and whose volume is referred to as dead space .

The lowering target is usually specified in meters above the respective valid reference altitude , in Germany in meters above sea ​​level (m above sea level). The term "lowering target" is standardized in DIN 4048 (hydraulic engineering terms).
