GP_betasdam Final data and code

Hydrological, biological, geomorphological, and geospatial datasets collected from the Great Plains (GP) used to develop the Beta Streamflow Duration Assessment Method (SDAM) for the GP. SDAMs are rapid, reach-scale indices or models that use physical and/or biological indicators to predict flow duration class. Three flow duration classes are used in the GP Beta SDAM: perennial, intermittent, and ephemeral. Perennial reaches have continuous surface flow and do not experience drying outside of extreme drought. Intermittent reaches have continuous surface flow for part of the year that is sustained by snowmelt and/or groundwater. Ephemeral reaches have surface flow only during and immediately following precipitation or snowmelt. These datasets are also located at the United States Environmental Protection Agency data repository at: https://doi.org/10.23719/1527943
