Winter growth and survival of juvenile Atlantic salmon (Salmo salar) in experimental raceways Winter growth and survival of juvenile Atlantic salmon (Salmo salar) in experimental raceways
We used experimental raceways to determine overwinter mortality of wild-reared immature and mature post-young-of-the-year Atlantic salmon (Salmo salar). Secondarily, we investigated the effects of differing treatments (velocity and shelter) on winter growth and survival. Overall survival from November to April was 94%, and survival of immature (98%) and mature (90%) parr, although...

WTAQ - A computer program for aquifer-test analysis of confined and unconfined aquifers WTAQ - A computer program for aquifer-test analysis of confined and unconfined aquifers
Computer program WTAQ was developed to implement a Laplace-transform analytical solution for axial-symmetric flow to a partially penetrating, finite-diameter well in a homogeneous and anisotropic unconfined (water-table) aquifer. The solution accounts for wellbore storage and skin effects at the pumped well, delayed response at an observation well, and delayed or instantaneous drainage...

Electrical imaging of tracer migration at the Massachusetts Military Reservation, Cape Cod Electrical imaging of tracer migration at the Massachusetts Military Reservation, Cape Cod
Electrical resistivity tomography (ERT) is examined as a method to provide spatially continuous information about aquifer properties through imaging of tracer flow and transport in an unconfined aquifer. Field data were collected at the Massachusetts Military Reservation, Cape Cod, Massachusetts, during the summer of 2002. High resolution images in both space and time of the movement of...

Object-based inversion of crosswell radar tomography data to monitor vegetable-oil injection experiment Object-based inversion of crosswell radar tomography data to monitor vegetable-oil injection experiment
Crosswell radar tomography methods can be used to dynamically image ground-water flow and mass transport associated with tracer tests, hydraulic tests, and natural physical processes. Dynamic imaging can be used to identify preferential flow paths and to help characterize complex aquifer heterogeneity. Unfortunately, because the raypath coverage of the interwell region is limited by the...

Continuous-resistivity profiling for coastal ground-water investigations: Three case studies Continuous-resistivity profiling for coastal ground-water investigations: Three case studies
Continuous-resistivity profiling (CRP) was used at three sites to investigate submarine groundwater discharge (SGD) and to delineate the subsurface saltwater/freshwater interface. At the first site, in Georgetown, South Carolina, CRP was used to locate possible areas of SGD in the Winyah Bay estuary. The data show evidence of SGD in the Pee Dee River, feeding into Winyah Bay, at...
