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.
