The program combines an intuitive user friendly interface and the analytical philosophy behind the popular slope stability program, STABL, developed at Purdue University. The main objective of this thesis is to develop and provide a novel approach to the upper bound limit analysis of slope stability using rigid elements. Approach: To calculate the slope of a line you need only two points from that line, (x1, y1) and (x2, y2). A spreadsheet supplied by the DNR took into account road slope, side slope, distance to stream, road surface precipitation, and soil as prescribed in the board manual. 2011; Verruijt 2012). Develop spreadsheets and databases, conduct technical analysis, and assist with preparation of CAD and GIS files; Perform field work as needed to support projects including but not limited to field observation and data collection, soil and water sample collection, drill rig observation, and support of other field investigations.

Parallel lines have equal slopes. Today, the use of computer programs has often removed the need for chart-based or coefficient-based methods of slope stability analysis using Ru.
