Water resource pollution load intensity measurement based on SWAT model

In order to solve the problems of high measurement time-consuming, high deviation and small area in traditional methods, a water resource pollution load intensity measurement based on SWAT model is proposed. Firstly, build a basic database, which contains different types of water resources data. Then, the hydrological characteristic data in the basic database are summarised, and the SWAT model is used to design the water pollution output coefficient model to obtain the change results of water pollution parameters; Finally, the comprehensive pollution index method is used to measure the pollution load intensity of water resources, obtain the standard pollution index, and get the final measurement result. The experimental results show that the water pollution load intensity measurement of this method takes less time, the measurement result deviation is low, and the area that can be measured is large, and the measurement effect is better.

Automated summary

This study proposes a water resource pollution load intensity measurement based on the SWAT model, aiming to solve the problems of high measurement time-consuming, high deviation, and small area in traditional methods. The method involves building a basic database, summarizing hydrological characteristic data, designing a water pollution output coefficient model using the SWAT model, and using the comprehensive pollution index method to measure the pollution load intensity of water resources. The experimental results demonstrate that this method reduces measurement time, improves measurement accuracy, and expands the measurable area.
