Analysis And Calculation Of Groundwater Resources In The Southern Valley Of Inner Mongolia Autonomous Region Ulanhot

The basic purpose of this writing is to identify the hydrogeological conditions in southern Inner Mongolia Wulanhaote City Valley area, the delineation of water-rich area, the evaluation of groundwater resources. After the results of submission, provide the basis for hydrogeological Ulanhot Valley area south to the construction of water and groundwater resources exploitation. Quaternary study area is mainly distributed in Tao children river valley, from the alluvial aquifer gravel, sand composition, rich water better. Diving rich water can be divided into three levels, one water-rich region (single well inflow>3000m3/d,10 "diameter, lm drawdown water inflow), located in the northeast of the work area and the southwest, drilling drawdown When 0.51-1.39m, water inflow 3886.70-5132.68m3/d, in terms of inflow of 3856.67-9628.51m3/d, the second is the amount of water medium area (single well inflow 1000-3000m3/d), mainly in the work area Most of the valley, drilling down deep when 1.54-3.51m, inflow of 4910.54-2901.15m3/d, in terms of inflow of 1028.90-2649.40m3/d, the third is a smaller area of water (single well inflow<1000m3/d), mainly in the workspace Valley fringe areas, drilling down deep when 2.81-3.69m, inflow of 1650.85-3191.96 m3/d, in terms of inflow of 447.39-878.05 m3/d, diving relatively good water quality salinity generally less than 0.5g/L, water chemistry type is generally HCO3-Ca, HCO3-Ca· Mg type, recharge sources diving mainly upstream section of groundwater recharge and surface water runoff for irrigation and recharge from rainfall into infiltration recharge, followed by flood infiltration recharge and lateral recharge, runoff and groundwater recharge upstream section, the main route of excretion excretion diving evaporation, runoff underground drain, labor exploitation excretion, of which the artificial exploitation excretion and evaporation excretion as the major excretion way groundwater use this method to calculate the water balance method, the calculation, the work area pore fissure water aquifer (s) storage capacity of 2.77×108m3, annual average natural recharge capacity of 2322.92×104m3/a, new exploitable resources to 1393.75×104m3/a, that is 3.82×104m3/d.
