Staff Directory

Cheng Cheng’s experience has focused on the areas of hydrogeology, hydrology, fluid mechanics, contaminant hydrogeology, field techniques in hydrogeology, statistical analysis in environmental management, remote sensing, and geographic information systems (GIS). Cheng excels in groundwater flow and contaminant transport modeling, and he is experienced in using MODFLOW-based groundwater flow and solute transport modeling codes including Groundwater Vistas, Visual-MODFLOW, and MODFLOW-SURFACT, MT3D, MODPATH, UCODE, PEST, as well as the finite-element modeling package FEFLOW. Cheng has developed groundwater models to assess the impacts of groundwater irrigation on streamflow depletion, to determine the ideal geological conditions for construction of riparian buffers to remove nitrate from groundwater, to evaluate the effects of new mine workings and expansions on water resources, and to determine the remediation goals at sites with contaminated sediments and soils. His field experience includes conducting pumping and slug tests, permeameter tests, seepage measurements, and soil and groundwater sampling. He also has hands-on experience in using a Geoprobe and knowledge of geologic logging, monitoring well installation, and general site inspections. He has provided technical expertise to mining companies, state agencies, federal agencies, counties, cities, and private companies on projects throughout the US, Sweden, and Australia.
