PTCOUNT PTCOUNT
A Fortran-77 Computer Program to Calculate the Areal Distribution of Mapped Data Points Using Count-Circle Methodology.
ORDSURVIV ORDSURVIV
Computes estimates of survival and recovery rates for band-recovery data with additional models for estimating reporting rate.
DOBSERV DOBSERV
A Double-observer approach for estimating detection probability and abundance from avian point counts.
JanbuGS, BishopGS, and FelleniusGS 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 Computer Programs for Telescopic Mesh Refinement using MODFLOW-96: MODTMR, TMRDIFF, and RIVGRID
MODTMR - A program for telescopic mesh refinement using MODFLOW TMRDIFF - A program to provide a means of comparing computed head or drawdown in local and regional models in applications of telescopic mesh refinement. RIVGRID - A program to construct MODFLOW data sets for head-dependent boundaries using grid-independent data sets
CloseTest 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 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 MSSRVRD
Computes survival-movement, capture and recovery probabilities from multi-strata capture-recapture-recovery data.
JOLLYAGE JOLLYAGE
Computes estimates of survival and capture probability for 2-age class open population capture-recapture models.
TMSURVIV TMSURVIV
Computes estimates of survival and capture probability and the proportion of transients in open population capture-recapture data.
Arkansas Waterwell Arkansas Waterwell
The Arkansas Water Well Construction Commission (AWWCC) was formed by the Arkansas General Assembly in 1969 to protect the general health, safety, and welfare of Arkansans by regulating water well construction and pump installation. The AWWCC’s rules provide a framework for proper development of underground water in an efficient, orderly, sanitary, reasonable, and safe manner.
DOSECOMP DOSECOMP
Analyzes dose responses for two populations, using the PROBIT model and the abbreviated protocol as described by Link et al(1996).
