One-Dimensional Transport with Equilibrium Chemistry (OTEQ): A Reactive Transport Model for Streams and Rivers One-Dimensional Transport with Equilibrium Chemistry (OTEQ): A Reactive Transport Model for Streams and Rivers
OTEQ is a mathematical simulation model used to characterize the fate and transport of waterborne solutes in streams and rivers. The model is formed by coupling a solute transport model with a chemical equilibrium submodel. The solute transport model is based on OTIS, a model that considers the physical processes of advection, dispersion, lateral inflow, and transient storage.
The Delaware River Basin Streamflow Estimator Tool (DRB-SET) The Delaware River Basin Streamflow Estimator Tool (DRB-SET)
The Delaware River Basin Streamflow Estimator Tool (DRB-SET) estimates baseline and altered streamflow at a daily time step for ungaged stream locations in the Delaware River Basin for water years 1960-2010.
SWQDM: Surface Water Quality Data Miner - Software page 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 software.

ZONEBUDGET is a program for computing subregional water budgets for MODFLOW ground-water flow models.
Data mining and analysis software for USGS NWIS Web streamflow data 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.
