In 2013, the first of several Regional Stream Quality Assessments (RSQA) was done in the Midwest United States. The Midwest Stream Quality Assessment (MSQA) was a collaborative study by the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA), the USGS Columbia Environmental Research Center, and the U.S. Environmental Protection Agency (USEPA) National Rivers and Streams Assessment (NRSA). One of the objectives of the RSQA, and thus the MSQA, is to characterize the relationships between water-quality stressors and stream ecology and to determine the relative effects of these stressors on aquatic biota within the streams (U.S. Geological Survey, 2012). To meet this objective, a framework of fundamental...

This data set provides the supporting data for the publication "What Makes a First Magnitude Sping?--Global Uncertainty Analysis of a Speleogenesis Model to Gain Insight into Karst Spring Genesis". This publication documents a speleogenesis model that was used to generate karst networks. Morris Method Global Sensitivity Analysis (MM-GSA) is used to efficiently sample input parameters to define a potential karst network. The MM-GSA provides information about sensitivity of hydrologic and transport response metrics (e.g., peak flows, peak timing, mass flux) to evaluated input parameters (e.g. network density, proto-conduit length distribution). There were 390 models in the analysis, therefore one replicate is provided...
