Software
An official USGS software project is code reviewed and approved at the bureau-level for distribution.
CENTROID
Tests the null hypothesis that two samples of recoveries belong to the same bivariate distribution.
DISTANCE
Allows design and analysis of distance sampling surveys to estimate density and abundance of a population
ECOSRCH
ECOSEARCH was developed as a first step to a testable, scientific basis for ecosystem management.
BROWNIE
Computes estimates of survival and recovery rates for 2-age class band-recovery data.
WinSLAMM (Source Loading and Management Model): Parameter and standard land-use files for Wisconsin
The SLAMM model is used to identify sources of pollutants in urban stormwater runoff and to evaluate management alternatives for reduce pollutants. These files provide stormwater flow and pollutant-concentration data for calibrating and verifying SLAMM for use in Wisconsin (WinSLAMM).
Soil-Water-Balance (SWB) for estimating groundwater recharge
The Soil-Water-Balance (SWB) model has been developed to allow estimates of potential recharge to be made quickly and easily. The code calculates components of the water balance at a daily time-step by means of a modified version of the Thornthwaite-Mather soil-moisture-balance approach.
PESTCommander
PESTCommander is an object-oriented Graphical User Interface (GUI) written in Python® that facilitates the management of model files ("file management") and remote launching and termination of slave computers across a distributed network of computers ("run management").
GENIE Version 2: A general model-independent TCP/IP run manager
GENIE Version 2 is a model-independent suite of programs that can be used to generally distribute, manage, and execute multiple model runs via a TCP/IP network. The suite consists of a file distribution interface, a run manager, a run executer, and a routine that can be compiled as part of a program and used to exchange model runs with the run manager.
TSPROC: a general time-series processor to assist in model calibration and result summarization
TSPROC (Time Series PROCessor) is a software package designed to assist in the calibration of models by editing and distilling time series datasets into more meaningful observations to be used in the optimization objective function. TSPROC uses a simple scripting language to process and analyze time series.
Modeling and Software
ModelMate
ModelMate is a graphical user interface (GUI) designed to facilitate model analysis
by software applications that invoke model simulations as external processes.
Fractured Rock Geophysical Toolbox Method Selection Tool (FRGT-MST)
The Fractured Rock Geophysical Toolbox Method Selection Tool (FRGT-MST) is an Excel-based tool for identification of geophysical methods most likely to be appropriate for project goals and site conditions.
