Cross Sections and 3D Modeling at Trihydro
Methods for Creating Cross Sections
ó Leapfrog Hydro
ó ArcGIS Desktop
ó Aquaveo Subsurface Analyst
Leapfrog Hydro 3D geological models and to create 3D models of contaminant plumes
2D cross sections cut through 3D models
Creating Cross Sections in ArcMap Manual cross section layout techniques
ó Use a grid to locate cross section features
ó Use a spreadsheet to manage coordinates
Aquaveo Subsurface Analyst
ó Build a catalog of subsurface data
ó Automate layout of cross section features
Use a grid to locate and place cross section features
Simple but time consuming
Using Arcmap as a Graphics Program
Using a Spreadsheet to Manage Coordinates
Reversing Cross Section Orientation The cross section orientation can be reversed using the Mirror Features Tool
Mirror Line
Reversed cross section Original cross section
Move new reversed cross section
Aquaveo Subsurface Analyst
Aquaveo Subsurface Analyst is an Arcmap extension which includes a toolbar and a toolbox.
Trihydro has begun utilizing Aquaveo Subsurface Analyst to create geologic cross sections within Arcmap.
Subsurface Analyst Data Organization Arc Hydro Groundwater (AHGW)
2D Cross Section (XS2D) Components Borehole Components
Creating a 2D Cross Section Text files are imported into an AGHW geodatabase
Borehole table
HGU table
Well Table
Creating a 2D Cross Section XS2D Catalog, delineated well and boring lines, and data frame are built

Adding Additional Features Soil samples, water samples, and water elevations may be added
Adding Well Construction Data Well construction data may be added to show riser, screen, fill, etc.
Plotting Geophysical Data Geophysical data may be plotted next to wells and borings
Complete Cross Section
Changing Vertical Exaggeration Changing the vertical scale of a cross section using the Scale tool
Data Requirements
• Table containing soil boring and well coordinates, elevations, and total depths
• Table containing well construction details in depths
• Table containing depths of lithologic contacts
• Tables containing water level, soil sample, and discrete water sample depths
• Tables containing geophysical log data
Lessons Learned
ó Where to get help ó Aquaveo YouTube channel ó Help documentation and tutorials available
ó Setup ó Installation of the software on a network server
ó Save often ó Tech support ó Aquaveo tech support has been very responsive
ó Huge time savings ó Improved accuracy
