Andrews, C., and Bradford, J., 2017, Simulated Soil Water Potential in National Parks and Monuments of the Southern Colorado Plateau, 1915-2099—Data: U.S. Geological Survey data release,


These data were simulated using the SOILWAT model and were intended to characterize soil-water conditions at different ecological sites on the Southern Colorado Plateau. SOILWAT is a daily, site-specific, multi soil-layer, ecosystem water-balance model, driven by daily meteorology, as well as site soil texture and vegetation. The sites simulated correspond with Inventory and Monitoring (I&M) plots established by the National Park Service’s (NPS) Southern Colorado Plateau Network (SCPN), which were established to capture the range of ecosystem conditions present in this network. Plant communities of the Southern Colorado Plateau Network (SCPN) are a vital sign for this region, enhancing habitat, stabilizing soils, and moderating hydrology. [...]

Field data collected by the NPS, including soil depth, texture, and vegetation composition, were used to inform the model. Weather data was obtained from the Livneh (Livneh et al. 2013) dataset for historical simulations (1915 – 2010) and from Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections (Reclamation, 2013) for future model runs (2020 -2099). In total, 300 sites were simulated using SOILWAT. The data here is summarized to the EcoSite level (varying n) and displays mean-daily soil water potential (SWP) for three different time periods, as well as annual mean-monthly SWP for the entire simulation period. These data can be used to inspect and monitor change in SWP conditions, to compare SWP across different Ecosites, and to inform management decisions in the face of climate uncertainty.
