Description
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.
