Bottom slope

from Wikipedia, the free encyclopedia

Bottom slope is the slope of the river or valley floor along the entire course of the river or part of it. The calculation takes place by dividing the height difference between the source and the mouth or the beginning and the end of the section by the length of the river . Usually the value is then converted into per mille or percent .

In the case of aqueducts or the construction of sewage or irrigation canals, a sufficient bottom slope is necessary to ensure a sufficient volume flow .
