ABSTRACT A groundwater hydraulic management model is used to identify the optimal strategy for allocating limited fresh‐water supplies and containing wastes in a hypothetical aquifer affected by brine contamination from surface disposal ponds. The present cost of pumping network potential supply interception wells minimized over five‐year planning period, subject set hydraulic, institutional, legal constraints. Hydraulic constraints are formulated using linear systems theory describe...

In order to quantify...

MOVE.1 is used widely throughout the hydrologic community...

More than 300 ambient monitoring sites in New Jersey have been identified by the Department of Environmental Protection (NJDEP) its integrated water-quality and assessment report (that is, 305(b) Report on general water quality 303(d) List waters that do not support their designated uses) as being impaired with respect to aquatic life; however, no unambiguous stressors (for example, nutrients or bacteria) identified. Because indeterminate nature broad range possible impairments, surrogate...
