Detailed Description

This video provides an overview of the USGS Fractured Rock Geophysical Toolbox Method Selection Tool. The Fractured Rock Geophysical Toolbox Method Selection Tool (FRGT-MST) is an Excel-based tool for identification of geophysical methods most likely to be appropriate for project goals and site conditions. We envision the FRGT-MST: 1) equipping remediation professionals with a tool to understand what is likely to be realistic and cost effective when contracting geophysical services, and 2) reducing applications of geophysics with unrealistic objectives or where methods are likely to fail. The 'toolbox' comprises 30 surface, cross-hole, and borehole geophysical methods. Additionally, hydrologic tests appropriate to fractured rock are included. The user enters information in two tables for site parameters and project goals. Based on user entry, a third table is populated with indicators for which methods support specified goals and are feasible at the site. Worksheet appendices provide detailed information on various methods. The toolbox and additional information are available from the USGS website, http://water.usgs.gov/ogw/bgas/frgt/

The USGS Fractured Rock Geophysical Toolbox Method Selection Tool is a spreadsheet-based decision support tool to assist in the selection of geophysical methods for groundwater studies in fractured rock.

Using the tool, scientists can easily and quickly identify hydrogeophysical methods that are appropriate for their study goals and field site conditions.

Users first enter information about the field site, 
such as depth to bedrock, borehole conditions (if applicable), and site geophysical properties.

Then the user enters information about the study objectives, such as mapping depth to bedrock
 or estimating hydraulic properties of discrete bedrock fractures or larger scale fracture zones.

The utility then returns summary information about a series of geophysical tools,
and how well they fit the study goals and the site conditions.

Buttons indicate whether a tool is appropriate for the given field site and study objectives, with green indicating suitable and red unsuitable.

Users can also get a summary overview of each tool, 
including information on the method and field work involved.

Project managers can use the USGS Fractured Rock Geophysical Toolbox Method Selection Tool to inform their decisions about geophysical tools that can enable groundwater studies to achieve their scientific objectives.

The toolbox and additional information are available from the USGS web site, http://water.usgs.gov/ogw/bgas/frgt/
