Reservoir flood prevention water level early warning system and method
The invention discloses a reservoir flood prevention water level early warning system and method, and belongs to the technical field of hydraulic engineering monitoring. The method comprises the following steps: acquiring rainfall data along an upstream river in real time, and monitoring water level change conditions of a reservoir entrance and a key river reach; on the basis of the obtained rainfall data and water level data, the upstream incoming water flow is calculated through a hydrological model, and the reservoir water level change trend within a certain time in the future is predicted and analyzed; according to the water level prediction result, the risk level of flood disasters encountered by the reservoir in a period of time in the future is evaluated, and corresponding early warning is given out; formulating and executing a flood discharge scheduling scheme according to a water level prediction result and risk assessment; the hydrological model is continuously optimized and improved, and the precision of flow calculation and water level prediction is improved, so that the accuracy and timeliness of early warning are improved.
本申请公开了一种水库防汛水位预警系统及方法，属于水利工程监测技术领域。该方法包括以下步骤：实时获取上游河流沿线降雨量数据，并监测水库入口处和关键河段的水位变化情况；基于获取的降雨量数据和水位数据，利用水文模型计算上游来水流量，对未来一定时间内水库水位变化趋势进行预测分析；根据水位预测结果，评估未来一段时间内水库遭遇洪涝灾害的风险等级，并发出相应预警；依据水位预测结果和风险评估，制定泄洪调度方案并执行；持续优化和改进水文模型，提高流量计算和水位预测的精度，从而提高预警的准确性和时效性。
