CRT: Cascade Routing Tool to Define and Visualize Flow Paths for Grid-Based Watershed Models
The U.S. Geological Survey Cascade Routing Tool (CRT) is a computer application for watershed models that include the coupled Groundwater and Surface-water FLOW model GSFLOW and the Precipitation-Runoff Modeling System (PRMS). CRT generates output to define cascading surface and shallow subsurface flow paths for grid-based model domains.
AquaPathogen X: A Template Database for Tracking Field Isolates of Aquatic Pathogens
Aquatic Pathogen Template Database (AquaPathogen X)
Random Landscape Tool 10.5
Random Landscape Tool uses a raster data source and a table of classifications to create a random landscape. The classification table allows the user to weight the probability of occurrence to certain classes and to spatially restrict the distribution of classes to certain areas (zones).

GRIDGEN: A Program for Generating Unstructured Finite-Volume Grids
GRIDGEN is a program for generating layered quadtree grids for MODFLOW-USG.
New York Streamflow Estimation Tool
The New York Streamflow Estimation Tool produces a complete estimated daily mean time series from which daily flow statistics can be estimated and a means for quantitative flow assessments at ungaged locations to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters.

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.
Analysis of Flows in Networks of Channels (AFINCH)
AFINCH (Analysis of Flows in Networks of CHannels) is a computer application designed to generate time series of monthly flows at stream segments and corresponding water yields at catchments defined in the National Hydrography Dataset (NHDPlus, v. 2).
UFINCH— A Method for Simulating Unit and Daily Flows in Networks of Channels Described by NHDPlus Using Continuous Flow Data at USGS Streamgages
The computer program UFINCH (Unit Flows in Networks of Channels) can be used to simulate unit (15-minute) flows in a network of streams defined within the medium resolution National Hydrography Dataset Plus with value added attributes (NHDPlus, v. 2).
ScienceBase
The U.S. Geological Survey is committed to enhancing and expanding information sharing and sound data management practices. Science teams directly use ScienceBase as an information management and collaboration platform and to release scientific data. ScienceBase is a central location that provides access to aggregated information derived from many data and information domains.
