A river simulation-based seasonal river and underground water interaction prediction method

Abstract

The invention discloses a river simulation-based seasonal river and underground water interaction prediction method, designs an algorithm for automatically determining a simulation path according to the characteristics of a river network, and is applied to a large complex natural / artificial river network. River numbering is random, the confluence relation and the shunting relation of a river network do not need to be considered, and work of a user is facilitated; Meanwhile, the function of shunting multiple rivers is perfected, and quantitative shunting and proportional shunting situations ofmultiple rivers and situations that the water diversion amount is larger than or smaller than the total water demand amount can be simulated; In addition, the method has higher accuracy for predictingthe flow of the interaction between the seasonal river and the underground water.

Description

Technical field [0001] The invention belongs to the technical field of automatic processing of hydrological and water resources data information, and specifically relates to the design of a method for predicting the interaction between seasonal rivers and groundwater based on river simulation. Background technique [0002] The mutual transformation of surface water and groundwater is a hydrological phenomenon ubiquitous in nature, and it is one of the basic attributes of water resources. In the evaluation and planning and management of water resources, great attention must be paid to the close hydraulic connection between surface water and groundwater. Only when the two are coupled together can they provide a solid foundation for the evaluation and planning and management of water resources. In the interaction system of surface water and groundwater, the significance of river-aquifer interaction research is the most important, that is, the relationship between seasonal rivers and...

Problems solved by technology

However, in the actual criss-crossing and complex river network, this work is cumbersome and error-prone. If the relationship between the river network or the order of confluence is not properly arranged, it will lead to calculation errors in the simulation results of the entire program. In the case of no check in the program, the errors generated are concealed. Difficult to troubleshoot

[0005] In addition, the existing simulation software is not flexible in the processing of artificially diverted rivers when generating river networks. When the river needs to be diverted according to the diversion ratio, the user needs to convert the diversion ratio into a fixed flow value and input it to each diversion. item, and cannot handle the situation where the divertable water is less than the total water demand of all downstream diverted rivers
