Version 1.3.01 release now available

Scoops3D evaluates slope stability throughout a digital landscape represented by a digital elevation model (DEM). The program uses a three-dimensional (3D) method of columns limit-equilibrium analysis to assess the stability of many potential landslides (typically millions) within a user-defined size range. For each potential landslide, Scoops3D assesses the stability of a rotational, spherical slip surface encompassing many DEM cells. It provides the least-stable potential landslide for each DEM cell in the landscape, as well the associated volumes and (or) areas.

The user's manual includes: the theoretical basis for the slope-stability analysis, requirements for constructing a 3D domain, a detailed operational guide and input/output file specifications, practical considerations for conducting an analysis, results of verification tests, and multiple examples illustrating the capabilities of Scoops3D.

Features

• Simple graphical user interface (Scoops3D-i)
• Easy integration of input/output files with Geographical Information System (GIS) software
• Subsurface material layers or full 3D distribution of material properties
• Pore pressure effects with piezometric surfaces or full 3D distributions of pore pressures or pressure heads
• 3D variably saturated pressure heads or pore pressures, including the effects of unsaturated suction stresses
