Description
Digital datasets were used to develop basin characteristics values that are used in multiple regression equations and tested for the use in predicting flow-duration curves (FDCs) in ungaged areas of Indiana. Several basin characteristics are easily derived from StreamStats basin delineations, such as basin area (https://streamstats.usgs.gov/ss/). Other basin characteristics require ancillary datasets as input. The data provided through this data release are those data that have been collected, tested, and ultimately selected as a basis for FDC development. These include PRISM 3-Month Average Precipitation, Thickness and Coarseness of Quaternary Sediments, and Soil Available Water Capacity.
There are 6 continuous parameter grids (CPGs; for a definition, see https://pubs.usgs.gov/ds/412/section3.html) included in the Indiana portion of this data release: PRISM December to February Average Precipitation (prdecfeb00_cpg), PRISM September to November Average Precipitation (prsepnov00_cpg), index of permeability of Quaternary surficial sediments (qss_permb_cpg), index of permeability of Quaternary surficial sediments multiplied by their thickness (permbxthick_cpg), STATSGO Permeability (statsperm_cpg), and Available Water Capacity (watcapinil_cpg).
