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.

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.
