Science and Products
Reference and Potential Evapotranspiration
Evapotranspiration can be computed as reference, potential, or actual evapotranspiration. Reference evapotranspiration is that from a grass surface that is well-watered. Potential evapotranspiration is that from a surface that has unlimited water (such as a lake).
Reference and potential evapotranspiration are computed at a 2-kilometer spatial resolution and daily timestep for the...
Evapotranspiration and Carbon-Flux Network
The U.S. Geological Survey Florida Evapotranspiration Network is a network of 15 data collection sites representing various land cover types, which provide long-term, accurate, and unbiased information that meets the needs of many diverse users. The USGS collects the evapotranspiration data needed by Federal, State, and local agencies for planning and operating water-resources projects and...
Conduit Flow Process (CFP): A Program to Simulate Turbulent or Laminar Groundwater Flow Conditions
Conduit Flow Process (CFP) allows simulation of laminar and turbulent flow within a standard MODFLOW layer and/or simulation of a hybrid model (one-dimensional pipe network coupled to MODFLOW).
