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

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 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.

TMSURVIV

Computes estimates of survival and capture probability and the proportion of transients in open population capture-recapture data.

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

Analyzes dose responses for two populations, using the PROBIT model and the abbreviated protocol as described by Link et al(1996).

MSSURVIV

Computes estimates of survival-movement and capture probability for open capture-recapture models.
