Hydrologic Soil Group for the Upper Colorado River Basin in Maurer et al. (2002) Climate Data resolution (hsg UCRB Maurer resolution.asc)

공공데이터포털

hsg_UCRB_Maurer_resolution.asc is an Esri ASCII grid representing the hydrologic soil group (HSG) for the Upper Colorado River Basin. The HSG for an area is determined by the least water-transmitting layer in the soil column. The Natural Resources Conservation Service (NRCS) classifies four HSGs from Group A (high infiltration capacity and low overland flow potential) to Group D (low infiltration capacity and high overland flow potential). In Soil-Water Balance recharge simulations, a lookup table incorporates HSG and land-cover information for each grid cell to define unique runoff curve numbers, vegetation rooting depths, interception values, and maximum daily recharge values.

Available Water Capacity for the Upper Colorado River Basin in Maurer et al. (2002) Climate Data resolution (awc UCRB Maurer resolution.asc)

공공데이터포털

awc_UCRB_Maurer_resolution.asc is an Esri ASCII grid representing the available water capacity (AWC) for the Upper Colorado River Basin. AWC is the amount of water that a soil can hold, and is between a soil’s field capacity and the wilting point. In Soil-Water Balance model recharge simulations, AWC is multiplied by root zone depth to define the maximum water capacity of a cell, and any soil-moisture exceeding this amount is converted to recharge.

Upper Colorado River Basin MODFLOW-NWT Model Application Data

공공데이터포털

A three-dimensional groundwater flow model, MODFLOW-NWT, was developed to simulate saturated groundwater hydrology, streamflow, and groundwater/surface-water interaction within the Colorado Plateau principal aquifer system. The model was used to evaluate and compare the hydrologic responses of groundwater and streamflow to natural and anthropogenic drivers of change between a recent wet period (1982-1999) and drought period (2000-2022) for four headwater subregions in the Upper Colorado River Basin. This child item contains all of the MODFLOW-NWT input and output files for the simulations described in the associated journal article (https://doi.org/10.1016/j.ejrh.2025.102554).
