Embodiment Construction

[0092] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0093] The present invention is a method for optimizing water distribution of canal systems in irrigation areas based on water inflow conditions. The flow chart is as follows: figure 2 shown, follow the steps below:

[0094] Suppose an irrigation area consists of two-level channels, such as figure 1 As shown, there is 1 first-level channel and z second-level channels.

[0095] Step 1. Collect necessary irrigation data;

[0096] The data in step 1 is as follows:

[0097] (1) Design flow q of z secondary channels dk , the unit is m 3 / s, 1≤k≤z, z is the number of secondary channels;

[0098] (2) The length of z secondary channels is l k ,, the unit is km;

[0099] (3) Collect the flow-time data of the water diversion outlet of a certain crop in a certain growth period, and draw the flow-time change process line;

[0100] (4) The total a...

Abstract

The invention discloses an irrigation district canal system optimization water distribution method based on incoming water conditions. The method specifically comprises the following steps that 1, needed data are collected; step 2, judging whether incoming water meets the water demand of crops or not, specifically, if W supply is greater than or equal to W demand, executing step 3, skipping steps 4 and 5, and executing the following steps; 2, if W supply is smaller than W demand and W'supply is larger than or equal to W demand, the step 3 and the step 4 are carried out, and the step 5 is skipped to carry out the following steps; 3, when W supply is smaller than W demand and W'supply is smaller than W demand, the following steps are carried out in sequence; 3, establishing a scene 1 model; 4, on the basis of the scene 1, adding an objective function to establish a model of a scene 2; 5, on the basis of the scene 2, a constraint condition is replaced to establish a model of a scene 3; step 6, model solving: solving the model through a genetic algorithm; and 7, summarizing the indexes to obtain a water distribution scheme. The problem that in the prior art, a water distribution model cannot distribute water according to actual incoming water is solved.

Description

technical field [0001] The invention belongs to the technical field of channel optimization and water distribution, and in particular relates to a method for optimizing water distribution in irrigation areas based on water inflow conditions. Background technique [0002] Channel optimization of water distribution refers to the optimization of water distribution flow and water distribution time by adopting certain methods and technologies in order to meet the needs of irrigation districts to distribute water to water users under the condition of a certain flow capacity of water distribution channels. In the actual water distribution process of the irrigation area, the water diversion flow and total amount of water diversion at the upstream water diversion outlet of the irrigation area are often determined by the superior management department based on the water intake permit and the actual situation. The water diversion volume of the upstream water diversion outlet is determin...
