specific Embodiment approach 1

[0026] Specific embodiment one: this embodiment is described in detail with reference to the figure, the method for predicting the influence of tidal action on river water quality based on the river water quality model described in this embodiment includes the following steps:

[0027] Step 1: Establish the EFDC river hydraulic water quality model, and obtain the change law of the river water level and the concentration of ammonia nitrogen and total phosphorus pollutants in the tidal river section under the influence of no tide as sediment disturbance within the set time;

[0028] Step 2: Use the tidal action impact module of the EDFC model to obtain the change law of the river water level and the concentration of pollutants such as ammonia nitrogen and total phosphorus in the tidal river section under the influence of the tide as sediment disturbance within the set time;

[0029] Step 3: Taking the change degree of the water quality index at the estuary of the tidal reach as t...

Abstract

The invention discloses a method for predicting influence of tidal action on river water quality based on a river water quality model in the technical field of water quality prediction. The problem that in the prior art that a traditional river water quality model is low in tidal reach water quality simulation accuracy is solved. According to the method for predicting the influence of the tidal action on the river water quality based on the river water quality model, the defect that a traditional river water quality model is low in accuracy of simulating the water quality of the tidal reach isovercome, and the method has important significance in pollutant control of the tidal reach seriously affected by the tidal action. Compared with a previous tidal influence evaluation means, the method has the advantages that the influence of the tidal action on the concentration of pollutants such as ammonia nitrogen and total phosphorus in the tidal river reach can be quantitatively identifiedon the basis of the river hydraulic water quality model, so that a more accurate and effective river pollution control means can be provided.

Description

technical field [0001] The invention relates to the technical field of water quality prediction, in particular to a method for predicting the impact of tidal action on river water quality based on a river water quality model. Background technique [0002] Urban water bodies are an important part of urban ecosystems. Due to the rapid development of urbanization in my country, urban rivers, which are the main receiving water bodies, are inevitably polluted to a certain extent, and even black and smelly. Studying the changing law of river pollution is the most important thing in the treatment and control of water pollution, and it is of great significance to the monitoring of river water quality and the rational use of water resources. Aiming at the migration and transformation of pollutants, domestic and foreign researchers have conducted a lot of research and established river water quality models such as WASP, QUAL2E, SWAT and MIKE series. The above water quality models hav...
