Swarm is a Java application designed to display and analyze seismic waveforms in real-time. Swarm is a Java application designed to display and analyze seismic waveforms in real-time.

Swarm is a Java application designed to display and analyze seismic waveforms in real-time. Swarm can connect to and read from a variety of different static and dynamics data sources, including Earthworm waveservers, IRIS DMCs, SEED and SAC files, and simple ASCII. Swarm has both time- and frequency-domain analysis tools, along with a simple but powerful mapping platfrom.

A Double-observer approach for estimating detection probability and abundance from avian point counts.

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.
