Water resource scheduling method based on land-atmosphere coupling

Abstract

The invention relates to a water resource scheduling method based on land-atmosphere coupling, and the method comprises the following steps: 1, carrying out the rainfall forecast according to a numerical atmospheric model WRF; 2, setting the parameters of a Hebei rainfall flood model; 3, carrying out the rainfall forecast, and driving the Hebei rainfall flood model to carry out the radial flow forecast; 4, determining a water resource scheduling scheme based on the radial flow forecast. Starting from the improvement of the radial flow forecast precision and the prolonging of the radial flow forecast period, the invention provides the method. The method can provide sufficient time for a decision maker to make a water resource scheduling scheme, can judge the water storage and discharge amount of a reservoir more precisely, makes the most of limited water resources, gives the fullest play to the benefits of water supply, is especially suitable for a north region which is the most affected by the activities of human beings, can achieve the rolling forecast of rainfall and radial flow through combining with weather forecast, provides a reasonable water resource scheduling basis for a water department, and is very universal.

AI Technical Summary

Benefits of technology

This patented technology allows people who live near or far from urban environments to efficiently manage their own water supplies while ensuring they have enough spare capacity needed during peak periods when there may be heavy rainwater impacts nearby buildings or other structures. It also helps predict future demand patterns over an area's entire range of weather conditions accurately without relying solely on data collected through remote sensors like temperature monitoring devices. Overall, this system makes it possible to optimize utilization of available water sources more effectively than traditional methods such as drilling well bore holes into underground pipes or building dams.

Problems solved by technology

Technological Problem: Current methodologies for planning and controlling water supply involve estimating future precipitation levels or monitoring groundwater movement patterns over an area beforehand. These techniques have limitations when trying to optimize water allocation due to factors such as seasonal variations (winter) and localized flooding caused by heavy snowfall during winter months. Additionally, current approaches only consider how well the waters were being utilised at different times throughout their lifespan, but cannot accurately determine whether these plans will lead to increased wastefulness if needed again later afterward.
