Abstract: A safety net system that is placed upright on the ground for restraining mud and debris slides is provided. The system includes at least one unit, each of which comprises at least one net panel that is disposed between two columns and is secured to continuous top and bottom ropes. The top rope extends from the bottom of one end column of a unit, through a guide at the top of that end column, through respective top guides of any interposed columns, through the top guide of the other end column, to a bottom end of that other end column. The bottom rope extends from the bottom end of one end column, through respective guides near the bottom of any interposed columns, to the bottom end of the other end column. Anchors are disposed laterally of each end column and uphill of each of the columns. Bracing cables extend from both the upper and bottom ends of each end column to the lateral anchors, and further bracing cables extend from both the upper and bottom ends of each of the columns to the uphill anchors.
