Flood discharge path of Huangbizhuang Reservoir

The flood discharge path of Huangbizhuang Reservoir mainly includes flood discharge tunnel, flood discharge canal and downstream river course.

Huangbizhuang Reservoir is an important water conservancy project in China and Henan Province, and it is also one of the largest reservoirs in China. At the critical moment of flood control, in order to ensure the safety of surrounding residents, the reservoir needs to carry out flood discharge to reduce the water level pressure of the reservoir. The flood discharge path of Huangbizhuang Reservoir is smooth. First of all, there is a spillway tunnel in the reservoir, which is located at the bottom of the reservoir dam. When the water level of the reservoir exceeds the safe water level, the spillway tunnel will automatically open and the excess water will flow out. This can avoid the risk of dam failure.

Secondly, the flood discharge water flows into the downstream flood discharge channel through the flood discharge tunnel. The spillway is a specially designed channel with a large flow. In this way, the flood discharge water can flow out of the reservoir smoothly, thus reducing the water level pressure of the reservoir. Finally, the flood water flows downstream along the spillway until it reaches the downstream river.

In this process, the reservoir will monitor the flood discharge and water level in real time to ensure the safety and effectiveness of flood discharge. At the same time, the relevant departments will also notify the downstream areas in advance and take necessary measures to reduce the possible impact of flood discharge.

flood prevention measure

1. Know the flood risk in advance: know the historical flood situation and flood risk level in this area so as to take preventive measures.

2. Strengthening houses and buildings: ensure the structural safety of houses and buildings, including strengthening roofs, walls and foundations, and repairing or replacing aging drainage systems.

3. Prepare emergency materials: reserve food, drinking water, medical supplies, first-aid medicines, batteries, flashlights and other emergency materials. In case of water and power failure during the flood.

4. Cleaning ditches and sewers: regularly clean ditches and sewers around the house to keep the water flowing smoothly and avoid flooding caused by accumulated water.

5. Take refuge in high places: If there is a great flood risk in this area, when the flood comes, try to avoid staying in low-lying areas and take refuge in high places, such as going upstairs or climbing.

6. Monitoring weather forecast and early warning: Pay close attention to weather forecast and flood early warning in time, so as to make preparations in advance and take necessary actions.

7. Carry important articles: carry important documents, valuables and personal emergency articles with you to avoid being damaged or lost by floods.
