Evaluation of proposed designs for streamflow monitoring structures at waste disposal sites

Description: Design of small surface water monitoring stations associated with waste sites requires an approach that balances several problems. The monitoring site must have a capacity for a wide range of flows, allow accurate measurements over the full performance range, minimize effects from accumulation of contaminated sediments, and minimize costs of construction and operation. Selecting a station design that takes these factors into consideration can be done systematically through use of formal decisio… more

Preliminary characterization of the F-Area Railroad Crosstie Pile at the Savannah River Site

Description: Historical information about the F-Area Railroad Crosstie Pile is limited. The unit is believed to have been a borrow area for earth fill that began receiving railroad crossties during the 1960s.

Smart'' pump and treat

Description: Lawrence Livermore National Laboratory (LLNL) is approaching the final phase of the Superfund decision-making process for site restoration and will soon initiate full scale cleanup. Despite some well-publicized failings of the pump and treat approach, we have concluded that intelligent application of this strategy if the best choice for ground water restoration at LLNL. Our proposed approach differs sufficiently from the pump and treat methods implemented at other sites that we call it smart'' … more

Phreatic flow on sloping soil layers from a finite source: An analytical solution

Description: Sloping clay layers beneath percolation ponds can cause infiltrating wastewater to pond and move in directions not predicted by vertical infiltration equations. This report presents a method for estimating the potential of wastewater from percolation sumps located over sloping clay layers to interact with nearby groundwater resources. The analytical solution developed is for steady-state conditions and includes a procedure to estimate the time needed to reach steady state. The fundamental assum… more

Development of an adjoint sensitivity method for site characterization, uncertainty analysis, and code calibration/validation

Description: The adjoint method is applied to groundwater flow-mass transport coupled equations in variably saturated media. The sensitivity coefficients derived by this method can be calculated by a single execution for each performance measure regardless of the number of parameters in question. The method provides an efficient and effective way to rank the importance of the parameters, so that data collection can be guided in support of site characterization programs. The developed code will facilitate th… more
