Conceptual model and numerical simulation of the groundwater-flow system of Bainbridge Island, Washington
Lonna M. Frans, Matthew P. Bachmann, Steve S. Sumioka, Theresa D. Olsen
2011, Scientific Investigations Report 2011-5021
Groundwater is the sole source of drinking water for the population of Bainbridge Island. Increased use of groundwater supplies on Bainbridge Island as the population has grown over time has created concern about the quantity of water available and whether saltwater intrusion will occur as groundwater usage increases. A groundwater-flow...
Development and assessment of a landscape-scale ecological threat index for the Lower Colorado River Basin
Craig P. Paukert, K.L. Pitts, Joanna B. Whittier, Julian D. Olden
2011, Ecological Indicators (11) 3014-310
Anthropogenic disturbances impact freshwater biota but are rarely incorporated into conservation planning due to the difficulties in quantifying threats. There is currently no widely accepted method to quantify disturbances, and determining how to measure threats to upstream catchments using disturbance metrics can be time consuming and subjective. We compared four...

Gabriel B. Senay, Michael E. Budde, James P. Verdin
2011, Agricultural Water Management (98) 606-618
Evapotranspiration (ET) can be derived from satellite data using surface energy balance principles. METRIC (Mapping EvapoTranspiration at high Resolution with Internalized Calibration) is one of the most widely used models available in the literature to estimate ET from satellite imagery. The Simplified Surface Energy Balance (SSEB) model is much easier...

Hydrogeology and simulation of groundwater flow in fractured rock in the Newark basin, Rockland County, New York
Richard M. Yager, Nicholas M. Ratcliffe
2011, Scientific Investigations Report 2010-5250
Groundwater in the Newark basin aquifer flows primarily through discrete water-bearing zones parallel to the strike and dip of bedding, whereas flow perpendicular to the strike is restricted, thereby imparting anisotropy to the groundwater flow field. The finite-element model SUTRA was used to represent bedrock structure in the aquifer by...
