INTRODUCTION
This tutorial is directed at first time users of savi3D, but experienced users may find it useful to step through the tutorial as an introduction to some of the new features and changes in savi3D 2.0. This tutorial can be used in two ways. If you have a copy of savi3D, you can use this as a guide while stepping through the appropriate functions in the EWB. If you don't have a copy of savi3D, this tutorial will acquaint you with the interface, organization, and data types of the savi3D scientific visuali zation software. For a full explanation of each feature, see the savi3D Users Guide. The image quality of all images in this on-line tutorial have been reduced to load faster in your browser.

ORGANIZATION
The tutorial is organized as a step by step guided tour through a sample groundwater remediation dataset and if possible, can accompany the user as they run savi3D for the first time. Each page of the tutorial has an image taken from savi3D. Numbered action steps take the user through the tutorial in sequence. To reach each stage in the tutorial, the user must have completed every preceding numbered step. Short descriptions of what the user should learn from the page and events which result from the user’ s actions are marked by a .

BACKGROUND INFORMATION
The data and map files used in this tutorial were taken from a demonstration project simulating the transport of a mass pollutant (benzene) by a subsurface water-flow. The medium is defined to be a porous, sandy soil beneath an industrial-building site and above a solid bedrock base. The spill location is at one end of the site and a freshwater drinking well is at the other.

In this simulation, a site-characterization was performed and a number of boreholes were drilled to determine the underground concentrations of the contaminant. These discrete observations were interpolated onto a grid and a predictive flow-transport model (PORFLOW) was used to simulate the spill’s movement. The goal was to remediate the site and keep the contaminant from reaching the drinking well. To do this, an extraction well was drilled between the spill and the drinking well.

The data for this tutorial are ficticious. The concentration values and units are for demonstration purposes only and are not intended to be realistic. In this tutorial, savi3D will be used to visualize the data collected, evaluate the effectiveness of a remediation strategy, and follow the progress of the simulated spill.

GETTING STARTED

From a Command Line :
To start the tutorial, move to the savi3D directory which is /savi3D (where is the path to which you loaded the savi3D distribution tape), and type savi3D to begin.

cd <path>/savi3D <return>
savi3D <return>

Using a Mouse :
To start the tutorial using a mouse, locate the Environmental WorkBench folder on your system and open it. Then double click on the icon labelled 'savi3D'.
