Solution Architecture

Water-environment quality forecast and warning system:Based on water-environment numerical models, build water-environment quality forecast systems for basins, rivers, lakes/reservoirs, and bays, providing forecast products for dissolved oxygen, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals, algae, and more for a future period; based on monitored and forecast water-quality data, warn on large water-quality changes exceeding standards, abnormal trend changes, and drinking-water-source water-quality risks over a given period.

Water-environment pollution-source assessment system:Water-environment pollution-source assessment includes point-source and nonpoint-source assessment. Point-source assessment comprehensively evaluates point sources quantitatively considering emission characteristics and amounts, and displays them on a map; nonpoint-source assessment uses numerical models to estimate river loads of nitrogen, phosphorus, heavy metals, and more, identifying key source areas and high-risk areas of nonpoint-source pollution.

Water-environment quality decision-support system:Compare current water quality and forecast results with water-quality planning targets, combine pollution-source inventories to assess water-quality improvement from pollution-control measures, and support scientifically formulating pollution-load reduction and spatial-allocation plans.

Sudden water-pollution-accident emergency simulation system:Can simulate pollutant migration and transformation based on accident location, pollutant type, leak amount, leak mode, meteorological and hydrological conditions, and more, calculating pollutant concentration distribution, time for pollutants to reach important downstream sections, and duration and spatial distribution of pollution belts exceeding specified thresholds.

River/sea outfall information-management system:Implement unified, standardized information management of river/sea outfalls, build an outfall “one map,” grasp existing outfall counts, distribution, changes, discharge status, and management status, and build an IT management platform for river and sea outfalls, providing management support to connect “shore and water” and “land and sea,” do a good job of water-pollution prevention, and improve water-environment quality.
