What if the downstream reservoir is demolished and the upstream reservoir is demolished?

The influence of reservoir construction on the upstream area: it increases the probability of crustal movement such as earthquake and landslide; The erosion and transportation of running water are weakened, but the accumulation is strengthened.

First of all, we need to know the flooded area of the reservoir and judge whether our home is flooded because of the flooded reservoir. Reservoir inundation area means that when the dam sluice is completed and water storage begins, the water level in the river will rise rapidly, the water level near the dam will reach the design water level, and the backwater away from the dam will drop by several thousandths or tens of thousands (usually referring to mountain and valley rivers), so that the land and cultivated land upstream of the dam will be inundated due to reservoir backwater, and its inundation area is called inundation area.

Article 7 of the State Council's Opinions on Improving the Support Policies for the Resettlement of Large and Medium-sized Reservoirs (Effective) stipulates that the physical investigation of the project area and the flooded area shall be conducted by the competent project department or the project legal person in conjunction with the local people's government of the project area and the flooded area; The physical investigation shall be comprehensive and accurate, and the results of the investigation shall be signed by the investigator and the respondent and publicized, and then signed by the relevant local people's government. Before the physical investigation begins, the provincial people's government where the project covers an area and inundates the area shall issue a notice prohibiting new construction projects and personnel from moving into the area, and make arrangements for the physical investigation.

Article 12 stipulates that the resettlement plan shall make arrangements for rural migrants, relocation of cities (towns), relocation of industrial and mining enterprises, relocation or reconstruction of special facilities, construction of protection projects, development and utilization of reservoir waters, measures to support reservoir migrants, compensation for land acquisition and estimation of resettlement funds. The production and living difficulties of residents in the affected areas above the flood line caused by reservoir impoundment should be included in the resettlement plan and properly handled in accordance with the principle of economy and rationality.
