SUTRA: A model for 2D or 3D saturated-unsaturated, variable-density ground-water flow with solute or energy transport
Clifford I. Voss, A.M. Provost
2002, Water-Resources Investigations Report 2002-4231
SUTRA (Saturated-Unsaturated Transport) is a computer program that simulates fluid movement and the transport of either energy or dissolved substances in a subsurface environment. This upgraded version of SUTRA adds the capability for three-dimensional simulation to the former code (Voss, 1984), which allowed only two-dimensional simulation. The code employs a...

T. Sommer, B. Harrell, M. Nobriga, R. Brown, P.B. Moyle, W. Kimmerer, Laurence E. Schemel
2001, Fisheries (25) 6-16
Unlike conventional flood control systems that frequently isolate rivers from ecologically-essential floodplain habitat, California's Yolo Bypass has been engineered to allow Sacramento Valley floodwaters to inundate a broad floodplain. From a flood control standpoint, the 24,000 ha leveed floodplain has been exceptionally successful based on its ability to convey up...

K.B. Raposa, C. T. Roman
2001, Wetlands (21) 451-461
Many New England salt marshes remain tide-restricted or are undergoing tidal restoration. Hydrologic manipulation of salt marshes affects marsh biogeochemistry and vegetation patterns, but responses by fishes and decapod crustaceans (nekton) remain unclear, This study examines nekton habitat-use patterns in the tide-restricted Hatches Harbor salt marsh (Provincetown, Massachusetts) relative to...
Nest survival of forest birds in the Mississippi Alluvial Valley
D.J. Twedt, R.R. Wilson, J. L. Henne-Kerr, R.B. Hamilton
2001, Journal of Wildlife Management (65) 450-460
In the Mississippi Alluvial Valley, flood control has led to a drastic reduction in the area of forest habitat and altered the patchwork of forest cover types. Silvicultural management of the remaining fragmented forests has changed to reflect the altered hydrology of the forests, current economic conditions of the area,...
Flow and habitat effects on juvenile fish abundance in natural and altered flow regimes
Mary C. Freeman, Z.H. Bowen, K.D. Bovee, E.R. Irwin
2001, Ecological Applications (11) 179-190
Conserving biological resources native to large river systems increasingly depends on how flow-regulated segments of these rivers are managed. Improving management will require a better understanding of linkages between river biota and temporal variability of flow and instream habitat. However, few studies have quantified responses of native fish...
