T/SMKX 001-2018 Critical water level determination

Scope

Scope: In the arid and semi-arid regions north of the Yangtze River in China, surface water and groundwater are regarded as a unified water body; various water sources such as streams, springs, wells, group wells, large-scale groundwater extraction, drop funnels, surface and underground reservoirs, etc. are included; especially drinking water, mineral water, geothermal water, Tanggangzi spring mud, oil fields, ports, power plants, and rural areas. This aims to fundamentally prevent over-extraction and pollution, strictly prevent water drying up and "disasters", give full play to the natural purification function of underground aquifers, achieve sustainable utilization of water resources, and fully serve the construction of a green and ecological homeland where life and water coexist in harmony! The treatment of man-made pollution will be addressed separately. Main technical content: 1. How to prevent over-extraction and pollution and achieve sustainable utilization of water resources in various water sources such as springs, wells, surface water, and underground reservoirs within the watershed, and prevent over-extraction of water resources and the natural purification of water quality resources; 2. In arid and semi-arid regions such as Shenyang, Liaoning, Northeast China, and North China, after more than 100 years of theory and practice, most water sources within the watershed take the form of water collection wells. How to achieve sustainable utilization of water resources or maintain the water resources bottom line for life during periods of no rainfall? This is the "Critical Water Level"; 3. When pumping water from water sources above the "Critical Water Level", the water volume can be maximized and stabilized, and the water can be naturally purified; 4. The critical water level of water sources is the high integration of water sources and energy or mechanical and electrical equipment, using energy equipment to accurately protect water sources and ensure the su
