What are the methods of water management?

There are many ways to control water, roughly summarized as follows:

1, dredging: dredging reservoirs, lakes, rivers and estuaries, deepening and widening of the water cross-section, blowing up reefs, removing wrecks and trees and other obstacles to the discharge of water, cutting curves to straighten the increase in the ratio of the water flow to improve the capacity of flood discharge.

2, build embankment: along the river bank, lake bank, bank construction of embankment berms, do not let the flood water overflow.

3, river training: branching rivers and branching waterways to build the dam dam, plug the branch of the strong trunk, rationalize the flow of water.

4, the construction of barrages or dams, manually regulate the flow, cut the flood peak.

5, planting trees, planting turf, to protect the ecological environment of the basin, in order to reduce the flood season from the ground runoff and groundwater runoff, in order to reduce the source of river sediment.

6, the management of riverbanks upstream of the river reservoir, to prevent collapse of mountains, landslides and mudslides, to reduce the source of river sediment.
