Enhancing the Simplified Surface Energy Balance (SSEB) Approach for Estimating Landscape ET: Validation with the METRIC model
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...
