西宁市贵德县河滨公园林场第四系含水层弥散试验研究
Study on Dispersion Test of Unconfined Aquifers in Riverside Forest Park of Guide County,Xining City
摘要
Abstract
The problem of groundwater pollution is growing,and the diffuse theory of solute transport is applied to real problems.Establishing the groundwater solute transport model,and correctly predicting the migration and the development trend of groundwater contaminants are the basis of protection of groundwater and pollution control.So determining the dispersion parameters is a critical step for the establishment of groundwater solute transport model and imposes a direct impact on the accuracy and precision of predicted results.In order to ana-lyze the underwater migration rules of Guide County in Xining City,the authors carry on a dispersion test of un-confined aquifers with the theory of radial flow convergence hydrodynamic dispersion,and calculate the disper-sion of the unconfined aquifer in test site,then get the longitudinal dispersivity (aL)of 0.843-0.998 cm and the transverse dispersivity (aT)experience inferred value of 0.17-0.20 cm,with which we can provide refer-ence data for establishing the groundwater solute transport model,predict groundwater pollution trends and also evaluate the groundwater environmental quality of this region.关键词
