Feasibility of Physical Hydraulic Modeling of Groundwater Pollutant Transport

摘要

A number of laboratory tests were performed to examine the feasibility of developing a simple and cost-effective technique for physical hydraulic modeling of groundwater pollutant transport. Instead of using conventional sand-tank models, rigid cement/mortar was considered for the model aquifer. Unsieved field sand of uniformity coefficient 2.5 was used for model aquifers and cylinder specimens. Initial tests on cylindrical specimens of mortar proved its potential usefulness as an aquifer material. Control over different geohydrological parameters was achieved by controlling mortar proportions and initial compaction. Using simple flow situations, hydraulic performance and pollution dispersion phenomena were tested and results compared well with theoretical values.
