Catchment-flowline network and selected model inputs for an enhanced and updated spatially referenced statistical assessment of dissolved-solids load sources and transport in streams of the Upper Colorado River Basin

This USGS data release consists of the synthetic stream network and associated catchments used to develop spatially referenced regressions on watershed attributes (SPARROW) model of dissolved-solids sources and transport in the Upper Colorado River Basin as well as geology and selected Basin Characterization Model (BCM) data used as input to the model.

The ecohydrology of roots in rocks

Large portions of the world are characterized by shallow soil underlain by weathered bedrock or cemented soil horizons. The implications of this substrate condition for ecohydrological processes have not been systematically explored, but misrepresentation in models could have profound consequences for climate prediction and global vegetation modelling. An issue of particular uncertainty is the characterization of water storage for these regions. A limited number of case studies have shown that plant water uptake is not restricted to shallow soils but can involve uptake from rock layers below. The mechanisms governing root?rock interactions are only beginning to be investigated. Research is needed to further characterize...

Selected Basin Characterization Model Parameters for the Upper Colorado River Basin

These data are derived from the Basin Characterization Model (BCM) and used as input to a total dissolved solids SPARROW model for the Upper Colorado River Basin. The BCM mechanistically models the pathways of precipitation into evapotranspiration, infiltration into soils, runoff, or percolation below the root zone to recharge groundwater (Flint and others, 2013). The dataset is composed of twelve, 270-meter resolution raster layers representing mean total annual values for water years 1985 - 2012 of actual evapotranspiration (aet), climatic water deficit (cwd), excess water (exc), snowmelt (mlt), snowpack (pck), potential evapotranspiration (pet), precipitation (ppt), recharge (rch), runoff (run), sublimation (sbl),...
