Description  RocFall (4.0) is a statistical analysis program designed to assist with a risk assessment of slopes at risk of rockfalls. Energy, velocity and "bounce height" envelopes for the entire slope are all determined by the program as is the location of rock endpoints. Distributions of energy, velocity and "bounce height" are also calculated along the slope profile. The distributions can be graphed and statistics are automatically calculated. It can also assist in determining remedial measures: the material properties of each slope segment can be changed and the analysis rerun, comparing the results. Information about the kinetic energy and location of impact on a barrier can help determine the capacity, size and location of barriers. It provides various ways of interacting with other Windows programs. All input and output data (formatted in tabular form) and screen captures, can be "pasted" into a word processor for report writing. It also allows "raw" data (e.g. the impact location on a barrier) to be "pasted" into a spreadsheet for more detailed analysis. (e.g. determining what fraction of the impact locations were above a certain height; or fitting a probability distribution to the data). Barriers: Any number of userdefined barriers at any angle or location on slope; Response of barriers to rock impact is userdefinable, with coefficient of restitution for each barrier; Breakable barriers. Slope: No restriction on slope geometry (i.e. any number of overhanging sections); Each slope segment can have different statistically defined material properties (RN, RT, friction angle); Rocks can begin sliding after coming to rest on any segment of the slope; Each slope vertex can be statistically defined (i.e. different standard deviations can be entered for each vertex location); Randomly varied angle (i.e. to simulate surface roughness of a slope segment); Material properties can be imported and exported; Import DXF and CRSP files. Rock Starting Location: Any number and combination of single location and line seeders can be specified; Each seeder has separate probability settings for velocity and mass of the rocks. Data Collectors: Any number of line "collectors" can be placed throughout the analysis area in order to gather information (velocity, location and energy) about the rocks as they pass through the collector. Calculations: Imperial units (ft, lb) or metric (m, kg); Angular velocity can be considered; RN can be scaled based on rock velocity and/or rock mass; Friction angle can be calculated from RT; Reverse analysis: Backcalculate slope coefficients of restitution from rock endpoint locations. Output: All graphs/plots can be copied to the clipboard for pasting into a word processor for report writing. Raw input and output data can be pasted into a spreadsheet for further analysis; Slope/barrier/collector geometry and associated parameters can be copied to the clipboard; InfoViewer presents a formatted summary of all input data; 1click grayscale for improved printing / black and white image capture; Saves screen to images files (BMP, JPG, EMF, WMF) or captures to the clipboard; Annotation toolkit: add text, arrows, lines, circles, etc. to slope views / Annotations can be saved with model.
