| Summary: | ability to contain the contamination within their site. account in the pumping design. Also, the establishment of and shape of the produced capture zone must be taken into and Tsang method predicted a much smaller capture zone than aquifer. conditions given the complexities of system. In this work, conditions. It was found that because the modeled area consultant work at a bulk fuel storage terminal has developed using MODFLOW. A steady state calibration was error alteration of recharge, specific yield, and boundary facility was going to prove detrimental to each operator's found that the semi-analytical modeling effort performed by hydraulic conductivity given appropriate boundary conditions. in thin, heterogeneous, unconfined aquifers. This study individual capture zones by each of the operators at the instigated the need to critically analyze modeling techniques involved with employing simplified models and simplifying MODFLOW was used in conjunction with the U.S.G.S. MODPATH numerical model. A two dimensional plan view model was Optimization techniques were shown somewhat valuable at the particle tracking program to simulate capture zones. It was prolonged recharge and recession events. A critical analysis provides an aquifer characterization such that a better regional water level fluctuations through time on the size represented only a small fraction of the aquifer as a whole site because of the limiting constraints provided by the thin than there numerical counterpart. Similarly, the Javandel that the boundaries must be varied through time to simulate the consultants contracted by Chevron predicted a capture the numerical model. It was shown that the effects of the numerically derived head distribution solved within The reported hydrocarbon contamination and subsequent transient calibration was developed by a systematic trial and understanding of the flow system can be input into an undertaken through the trial and error alteration of Using the steady state model as initial conditions, a was performed to evaluate the potential problems and errors zone and drawdown at each well that were significantly less |
