This page describes the currently available demonstrations of how to use BUGS™ Scratchpad. These demonstrations are now a part of the on-line version of the User's Manual. Additional examples can be found in the on-line version of A Two Dimensional Numerical Model for Simulating the Movement and Biodegradation of Contaminants in a Saturated Aquifer, a Master's Thesis by Jason E. Fabritz, 1995.
Conservative Tracer Test, User’s Manual
This tutorial presents how to enter the simplest of simulations, a conservative tracer experiment in a one dimensional aquifer with a constant concentration source at the inlet. It includes both a text description and screen snapshotss. You won't even need BUGS™ Scratchpad to get a feel for the program using this document.
Kinetic Sorption/Desorption, User’s Manual
This tutorial presents how to modify the previous example to include kinetic sorption and desorption in the simulation.
First Order Decay, User’s Manual
This tutorial presents how to modify the Kinetic Sorption/Desorption lesson to include first order decay.
Two-Dimensional Conservative Tracer, User’s Manual
This tutorial expands the first tutorial example into two dimensions.
Saturated Confined aquifer with a TCE spill, Tech. Manual
This example analyzes a one-dimensional flow and transport problem in a saturated confined aquifer contaminated with a TCE spill. Chemical processes and reactions modeled include TCE dissolution, sorption, and biodegradation by methanotrophs
