Aqueous geochemistry: Piper, Stiff and Durov diagrams |
|
RockWorks offers several utilities for manipulating and displaying your hydrochemistry data, including the most popular aqueous geochemistry plots- Piper diagrams and Stiff diagrams. |
| Piper diagrams |
Piper diagrams illustrate ion concentrations and total dissolved solids for multiple samples.

| Hydrology tools |
|
The hydrology tools available in RockWorks2006 include well drawdown and hydrographs: |
|
| Well drawdown |
- Compute drawdown for a single well using the Theis equation and display as a report or diagram
- Compute drawdown for multiple pumping or injection wells listed in data sheet (also using Theis equation), display as 2D or 3D potentiometric surface map

| Hydrographs |
|
Hydrographs display aquifer water levels and precipitation over time, thereby indicating percolation rates. |
