What are the hydrological characteristics and water system characteristics?

1, sediment concentration, from the area where the river flows.

2. In the flood season, the climatic conditions of the area where the river flows.

3. Ice age, see if there are any rivers in the ice age, such as Heilongjiang, where the ice age is longer.

4, runoff, from many aspects, such as the number of tributaries, regional rainfall is sufficient.

5, hydropower, see if the gap between rivers is very large.

Water system characteristics

1, river length, flow direction?

2. Basin area?

3. The number and form of tributaries?

4. River network density?

5, drop or canyon distribution

Extended data

The characteristics of river system and hydrology depend on the topography, climate and human activities of the basin. Human activities have an impact by changing the underlying surface.

For example, human cutting down vegetation will lead to an increase in surface runoff, a sharp rise and fall of river water level, a greater sediment concentration, siltation of river channels and elevation of river beds; Planting trees and grass will reduce surface runoff, the fluctuation of river water level will be smaller and the sediment concentration will be smaller. Hardened pavement (cement pavement) will increase surface runoff and the river water level will rise and fall sharply; Laying permeable bricks will reduce surface runoff, increase underground runoff and reduce the fluctuation range of river water level.

Repairing the reservoir can regulate the flow of the river, stabilize the downstream water level and reduce the sediment concentration of the downstream river. Reclamation around the lake will weaken the regulation function of the lake and the water level will rise and fall sharply.
