Abstract

The invention relates to a long-distance water delivery open channel water quality simulation prediction method and system. The method comprises the following steps: according to the trend of a water delivery open channel, a plurality of dry and wet settlement monitoring devices being arranged along the channel, and obtaining the atmospheric sediment mass and rainfall; determining the pollutant source intensity in dry sedimentation according to the mass of the atmospheric sediments; determining the pollutant source intensity in wet sedimentation according to the rainfall; constructing a long-distance water delivery open channel water quality model considering the influence of dry and wet sedimentation based on the pollutant source intensity in dry sedimentation and the pollutant source intensity in wet sedimentation; conducting discrete processing on the long-distance water delivery open channel water quality model, and determining the long-distance water delivery open channel water quality model expressed in a differential format; and obtaining actual measurement data of the water delivery open channel, taking the actual measurement data as a boundary condition of the long-distance water delivery open channel water quality model expressed by the difference format, solving the long-distance water delivery open channel water quality model expressed by the difference format according to the boundary condition, and determining the water quality of the water delivery open channel. The method can accurately evaluate the water quality of the large water delivery open channel.

Description

technical field [0001] The invention relates to the field of research on river water quality protection, in particular to a method and system for simulating and predicting water quality of long-distance water delivery open channels. Background technique [0002] The success or failure of water quality protection in water transfer determines the success or failure of a water diversion project, especially for a water diversion project that is used as a source of drinking water. Water quality protection from the source of water transfer to the water transfer line and then to the diversion channel is very important. Under normal circumstances, water diversion projects that use open channel water delivery mostly adopt a three-dimensional intersection model, so that the open channel for water delivery does not exchange with the local water system, and does not have direct contact with local pollution sources. The purpose is also to ensure the quality of water delivery. However, th...
