Software
An official USGS software project is code reviewed and approved at the bureau-level for distribution.
SutraPlot: A Windows-Based Visualization Tool for 2D and 3D SUTRA Simulations
SutraPlot creates 2D and rotatable 3D plots from 2D and 3D SUTRA output data.
CountRemoval
A removal model for estimating detection probabilities from point count surveys.
VolatileCalc
VolatileCalc calculates H2O-CO2-melt equilibrium for the rhyolite and basalt systems.
PTCOUNT
A Fortran-77 Computer Program to Calculate the Areal Distribution of Mapped Data Points Using Count-Circle Methodology.
ORDSURVIV
Computes estimates of survival and recovery rates for band-recovery data with additional models for estimating reporting rate.
DOBSERV
A Double-observer approach for estimating detection probability and abundance from avian point counts.
JanbuGS, BishopGS, and FelleniusGS
Fortran-77 programs for limit-equilibrium slope-stability analysis.
Computer Programs for Telescopic Mesh Refinement using MODFLOW-96: MODTMR, TMRDIFF, and RIVGRID
CloseTest
CloseTest is a Windows program for testing capture-recapture data
One-Dimensional Transport with Inflow and Storage (OTIS): A Solute Transport Model for Streams and Rivers
OTIS is a mathematical simulation model used to characterize the fate and transport of water-borne solutes in streams and rivers.
The governing equation underlying the model is the advection-dispersion equation with additional terms to account for transient storage, lateral inflow, first-order decay, and sorption.
MSSRVRD
Computes survival-movement, capture and recovery probabilities from multi-strata capture-recapture-recovery data.
JOLLYAGE
Computes estimates of survival and capture probability for 2-age class open population capture-recapture models.
