Irrigation District Water Management System

Irrigation district modernization is an important part of agricultural modernization, among which smart irrigation districts are an important symbol of modern irrigation districts. A comprehensive smart irrigation district system with the “four forecast” functions of forecasting, early warning, rehearsal and planning should be established to provide strong technical support for strengthening water supply security in irrigation districts.

The construction of irrigation district water metering system is the basic work for saving water resources in irrigation districts , and water use management in irrigation districts is an important part of it. Hengrunan has independently developed a complete irrigation district water use management system based on its own experience in the water conservancy industry.

The main contents of the PC software platform include modules such as water distribution and irrigation management, water use planning , water distribution plan, water volume management, and water fee management.

Water distribution and irrigation management

Water distribution and irrigation management includes planting information, water demand plan, water distribution plan and irrigation schedule.

1) Planting information

Planting information includes crop types, irrigation areas, etc., and provides water supply units and water users with information configuration functions on crop types and irrigation areas each year. Through the configuration of planting structure information, it provides data basis for water users to fill in water demand plans and for water supply units to formulate configuration plans.

Water use plan

In order to make a prediction, it is necessary to first conduct a statistical correlation analysis between the previous measured water volume and the annual water diversion volume, and to make revisions as the measured data increases to reflect the latest data results.

Develop a water use plan based on water demand in the irrigation area over the years and based on the type of crop area and other water needs.

Water distribution plan

An annual water supply plan is formulated based on a comprehensive assessment of factors such as crop water demand in the irrigation area, water inflow in the previous year, water supply capacity, disaster conditions, precipitation, and social economy.

According to the water demand plan, a phased water supply plan is carried out. Based on the monitoring of the canal head water level, channel water level and typical field water level (such as high paddy field water level and tailwater field water level), the plan should waste as little water as possible while ensuring agricultural irrigation water supply.

Water volume management

1) Water volume statistics

It provides water volume statistics functions, including total water volume statistics, water volume statistics by area, water volume statistics by time scale, comparative statistics of water volume over the years, etc. It also provides reporting functions, including water volume reports, annual water consumption briefings, etc.

Water fee management

1) Water fee collection and management

Water fee collection management realizes the maintenance and management of data such as the actual water volume, payable water fees, and actual payment of water users at all levels in the irrigation area. Statistics and analysis are performed on the user’s water fee balance and arrears, and reports can be generated according to conditions and printing functions can be provided.

2) Water fee settlement

You can select the settlement time period and make a list of main and branch canal water charges, including the actual collection, balance, branch canal outlet, quota water volume, cumulative settlement water volume, cumulative settlement amount, water volume within the quota, unit price within the quota, amount within the quota, extra-quota water volume, extra-quota unit price, extra-quota amount and other information.

The smart irrigation district software platform builds a data platform based on remote sensing big data, data collected by intelligent sensing equipment, basic management data, etc., and constructs seven business modules for irrigation districts: one map, information monitoring, automatic control, water use management, engineering management, operation and maintenance inspection management, and system management. It also provides a mobile APP and WeChat public service platform, which are open to irrigation district managers, superior authorities, farmland irrigation water institutions and individuals, etc., according to the permission level.

Each monitoring system can be used as an independent system. The platform’s general application support platform integrates various monitoring systems and builds application systems based on a unified architecture. It is integrated into a unified platform through a single sign-on deployment method, and the data reporting and exchange functions of data centers at all levels are realized through the data exchange system.
