Massachusetts Sustainable-Yield Estimator (MASYE) application software (version 2.0)
This software release provides the database application that runs the Massachusetts Sustainable-Yield Estimator (MA SYE) computer program (version 2.0).
Connecticut Streamflow and Sustainable Water Use Estimator (CTSSWUE Version 1.0) application software
This software release provides the database application that runs the Connecticut Streamflow and Sustainable Water Use Estimator (CT SSWUE) computer program (version 1.0).
The Massachusetts Reservoir Simulation Tool
The Massachusetts Reservoir Simulation Tool is a screening-level model developed to examine the effects of reservoirs on the natural streamflow of streams in Massachusetts. The Massachusetts Reservoir Simulation Tool simulates the daily water balance equation of a water supply reservoir and estimates the magnitude, frequency and duration of spillage below the dam over the period of record.
HyDroDSS: Hydrologic Drought Decision Support System - Software page
Overview
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.
SELDM: Stochastic Empirical Loading and Dilution Model - Software page
Overview
The Stochastic Empirical Loading and Dilution Model (SELDM) is designed to transform complex scientific data into meaningful information about the risk of adverse effects of runoff on receiving waters, the potential need for mitigation measures, and the potential effectiveness of such management measures for reducing these risks.
HRDB: Highway Runoff DataBase - Software page
Overview
The highway-runoff database (HRDB) was developed to serve as a data warehouse for current and future highway-runoff data sets. The database can be used by transportation agencies and researchers as a data warehouse to document information about a data set, monitoring site(s), highway-runoff data (including precipitation, runoff, and event mean concentrations...
SWQDM: Surface Water Quality Data Miner - Software page
Overview
The SWQDM database application was developed by the U.S. Geological Survey in cooperation with the Federal Highway Administration for use in the analysis of regional and national hydrologic data sets. The surface-water quality data miner (SWQDM) database application was developed to coordinate use of NWIS Web, NWiz, and the Kendall-Theil Robust Line analysis...
Data mining and analysis software for USGS NWIS Web streamflow data
Overview
Five computer programs were developed for obtaining and analyzing streamflow from the National Water Information System (NWISWeb). The programs were developed as part of a study by the U.S. Geological Survey, in cooperation with the Federal Highway Administration, to develop a stochastic empirical loading and dilution model.
KTRLine: Kendall-Theil Robust Line - Software page
Overview
The Kendall-Theil Robust Line software (KTRLine—version 1.0) is a Visual Basic program that may be used with the Microsoft Windows operating system to calculate parameters for robust, nonparametric estimates of linear-regression coefficients between two continuous variables.
VBVenn: Visual Basic Venn diagram - Software page
Overview
VBVenn is a Visual Basic program that calculates the size and position of two circles to construct a quantitative Venn diagram. It is a simple one-form program with a fairly intuitive user interface.
