Surfer - Faults and Breaklines
 
Define faults and breaklines when gridding your data. The data on one side of the fault will not be directly used to calculate grid node values on the other side of the fault. When the gridding algorithm sees a breakline, any data points that lie directly on the breakline take precedence over an interpolated value. Use breaklines to define streamlines, ridges, and other breaks in slopes. Unlike faults, breaklines are not barriers to information flow and the gridding algorithm can cross the breakline to use a point on the other side. The gridding methods that support faults are: Inverse Distance to a Power, Minimum Curvature, Nearest Neighbor, and Data Metrics. Breaklines are supported by: Inverse Distance to a Power, Kriging, Minimum Curvature, Nearest Neighbor, Radial Basis Function, Moving Average, Data Metrics, and Local Polynomial gridding methods.

Groundwater Management Model for the Lower Murray, Australia

The aim of this project was to develop a groundwater management model which was used by natural resource managers and the community to better manage the groundwater resources of the Lower Murray. This region has been designated as a potential high-risk aquifer system.
