Solution of the advection-dispersion equation by a finite-volume eulerian-lagrangian local adjoint method Solution of the advection-dispersion equation by a finite-volume eulerian-lagrangian local adjoint method
A finite-volume Eulerian-Lagrangian local adjoint method for solution of the advection-dispersion equation is developed and discussed. The method is mass conservative and can solve advection-dominated ground-water solute-transport problems accurately and efficiently. An integrated finite-difference approach is used in the method. A key component of the method is that the integral...

Study of salt transport processes in Delaware Bay Study of salt transport processes in Delaware Bay
The study described here is a subset of a broader climate-related study, and is focused primarily on salinity intrusion into Delaware Bay and River. Given changes in freshwater discharge into the Delaware River as determined from the larger study, and given probable sea level rise estimates, the purpose here is to calculate the distribution of salinity within Delaware Bay and River. The...

Synthetic organic agrochemicals in the lower Mississippi River and its major tributaries: Distribution, transport and fate Synthetic organic agrochemicals in the lower Mississippi River and its major tributaries: Distribution, transport and fate
The Mississippi River and its major tributaries transport herbicides and their degradation products from agricultural areas in the mid-western U.S.A. These compounds include atrazine and its degradation products (desethyl- and desisopropylatrazine), simazine, cyanazine, metolachlor, and alachlor and its degradation products (2-chloro-2',6'-diethylacetanilide, 2-hydroxy-2',6'...

Tale of three prospects Tale of three prospects
Most high-temperature, hydrothermal-convection systems probably are heated by bodies of magma (and/or hot plutons), whose presence is suggested by geologically young, if not active volcanism. Study of a young volcanic area provides information about the general thermal status of the underlying heat source, and detailed information about the time-space-volume-composition (TSVC)...

The effect of rock type, grain size, sorting, permeability, and moisture on measurements of radon in soil gas: A comparison of two measurement techniques The effect of rock type, grain size, sorting, permeability, and moisture on measurements of radon in soil gas: A comparison of two measurement techniques
Soil surveys of radon conducted in the Coastal Plain of New Jersey, Alabama and Texas indicate that soil composition and grain size exert the strongest control on the concentration of radon measured. Soil-gas radon was measured in-situ using two techniques; one developed by G. Michael REIMER of the U.S. Geological Survey; the other developed by Rogers and Associates Engineering Corp. for...

Tide- and wind-driven flushing of Boston Harbor, Massachusetts Tide- and wind-driven flushing of Boston Harbor, Massachusetts
The flushing of Boston Harbor, a shallow, tidally dominated embayment with little fresh water input, is investigated using a depth-averaged model. The modeled tidal currents exhibit strong spatial variability and ebb/flood asymmetry due to complex topography and coastline geometry and were verified by shipboard acoustic Doppler current profiler measurements. At the inlets to the harbor...
