Upper Colorado River Basin SPARROW model catchments and synthetic stream network - 2017 This data collection consists of a synthetic stream network and associated catchments developed as the foundation for a Spatially Referenced Regressions on Watershed Attributes (SPARROW) dissolved-solids source and transport model for the Upper Colorado River Basin (UCRB). The SPARROW model requires a hydrologically connected representation of a stream network through which loads are transported from an upstream reach to the next reach downstream (Schwarz and others, 2006; Moore and others, 2004). Each stream reach or segment within this synthetic stream network has an associated local drainage area or catchment used to calculate catchment characteristics that may have an effect on loads being modeled. The synthetic...

These woodlands likely dominated alluvial reaches of all streams where a snowmelt-driven spring flood was the major factor driving geomorphic and vegetation dynamics. These woodlands were also among the first habitats to undergo transformation as the regions land and water resources were developed.The PI coauthored a paper (Andersen et al. 2007) on assessing the amount of native Fremont cottonwood forest remaining on floodplains in 26 subbasins...

The data release was produced in compliance with 'open data' requirements as a way to make the scientific products associated with USGS research efforts and publications available to the public. This dataset comprises SWB model results from runs using projected climate data, summarized by sub-basin on a monthly basis, and there are 4 separate datafiles associated with this Data Release: 1. SWB model results for actual evapotranspiration (AET), summarized by sub-basin on a monthly basis from 1950 through 2099 2. SWB model results for potential evapotranspiration (PET), summarized... Categories: Data; Types: Citation; Tags: Upper Colorado River Basin, climate change, groundwater recharge Modeling Low Stream Flows and Assessing the Ecological Impacts of Potential Stream Drying under Climate Change in the Upper Colorado River Basin Streamflows in late spring and summer have declined over the last century in the western U.S. and mean annual streamflow is projected to decrease by six to 25% over the next 100 years. In arid and semi-arid regions of the western US, it is likely that some perennial streams will shift to intermittent flow regimes in response to climate-driven changes in timing and magnitude of precipitation, runoff, and evaporation. The project will address the following two research question: how will small stream (1st-3rd order) low flow hydrology be impacted by predicted longer, drier summers in the Upper Colorado River Basin under climate change and in turn, what will be the resulting impacts on riparian plant communities?...

Categories: Data; Types: Citation; Tags: Upper Colorado River Basin, climate change, groundwater recharge Generalized 1:500,000-scale geology of the Upper Colorado River Basin This generalized geology dataset was developed as input to a total dissolved solids Spatially Referenced Regressions on Watershed Attributes (SPARROW) model for the Upper Colorado River Basin (UCRB; Kenney and others, 2009) and for a more recent update to that model. The largest source of naturally generated dissolved solids in streams of the UCRB is the rocks underlying stream basins, particularly rocks high in dissolvable minerals. For the purposes of modeling, the scale of the geologic dataset optimally should be similar to the scale of the stream-catchment network used in the model but simplified to reduce the number of geologic units represented in the data. This dataset was developed to meet both scale and...

Bottomland vegetation has been altered as well, with invasion of non-native species, increases in wildfire and human disturbance, and currently, rapid shifts in riparian communities due to biological and mechanical tamarisk control efforts. In light of these conditions, land managers are in need of scientific information to support management of vegetation communities for values such as healthy populations of sensitive fish and wildlife species and human recreation. We propose to address these...
