This package facilitates the analysis and evaluation of hydrologic model streamflow output during periods of drought. This package calculates the Cohen's Kappa, Spearman correlation coefficient, ratio of standard deviation, percent bias, normalized mean absolute error (NMAE) in the annual time series of drought duration, NMAE in the annual times series of the distance the minimum...

This release consists of data collected from 26 plots in two national parks over a 19-year period. The data consists of plot-level seed counts for three genera, number of seed traps, live tree basal area, plot area, and climate metrics from the gridmet gridded data set, the daymet gridded data set, the PRISM gridded data set, and two nearby COOP stations.

This software release provides the database application that runs the Massachusetts Sustainable-Yield Estimator (MA SYE) computer program (version 2.0). The MA SYE was developed by the U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, to provide a planning-level decision-support tool designed to help decision makers estimate daily mean...

StreamStats is a Web application that incorporates a Geographic Information System (GIS) to provide users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes.

The HyDroDSS is designed to provide water managers with risk-based information for balancing water-supply needs and aquatic-habitat protection goals to mitigate potential effects of hydrologic drought.
