Study on river regulation measures of dried-up rivers of Haihe River basin, China
In recent years, the ecological environment of plain rivers within Haihe River basin is questionable because of severe water shortages. Most of the rivers dry up regularly and it is therefore necessary to take measures to improve the river ecological environment. Meanwhile, flood control is the principal function for most of the dried-up rivers, so river regulation works for flood control also ...

A multi-criteria decision-making model dealing with correlation among criteria for reservoir flood control operation
Flood control operation in a multi-reservoir system is a multi-criteria decision-making (MCDM) problem, in which the considered criteria are often correlated with each other. In this paper, we propose an MCDM model for reservoir flood control operation to deal with correlation among criteria. Considering the flood control safety of reservoirs and downstream protected regions, we establish the ...

Be Prepared for Flooding
What are some reasons for flooding? There are many reasons for flooding and not all flooding causes damage or is catastrophic. Flooding mostly occurs when stream or river systems fill beyond their capacity. It can also happen on lake or coastal shorelines during periods of high water levels encroach on flood plains or low-lying areas. The intensity and duration of precipitation saturates the ...
