All simulations were performed using the Universal Distinct Element Code (UDEC) version 7.0. We simulated progressive damage for three different landslide types: slab toppling, flexural toppling, and planar sliding. For each scenario we simulated several stages of progressive rock slope damage. Subsequently, we recorded the resonance response of the rock slope at each stage by measuring x-direction velocity at one or more measuring points throughout the model. 1. File List A. Filename: DynamicRuns.zip Short description: Dynamic model outputs from UDEC for slab toppling, flexural toppling, and planar sliding rock slope damage models in .csv format. Subfolders contain files for each model scenario. Each .csv file contains x-velocity data recorded in units of meters per second at one or more monitoring points distributed along the surface of the rock slope instability. Data were recorded at a single point (M1) for the slab toppling case and at 15 points (M1–M15) for the flexural toppling and planar sliding cases. X-velocity data were recorded for each model step (column labeled 'step'), which relates to time in seconds given the prescribed model timestep for each case. The total model run times were 35 seconds for the slab toppling and planar sliding cases and 20 seconds for the flexural toppling case. Results from the following failure stages are included for each scenario: slab toppling: s0 (undamaged) through s7 (most damaged); flexural toppling: t0 (undamaged) through t7 (most damaged); planar sliding: p0 (undamaged) through p6 (most damaged). For each model stage (e.g., p0), we additionally recorded x-velocities for a reference run (no dynamic input; e.g., 'p0_ref.csv') to compare with the dynamic run (e.g., 'p0_run.csv') and subtract out modeling artifacts when necessary. B. Filename: Code.zip Short description: UDEC executable files (.uddat) used to build and run each model simulation. Each scenario (i.e., slab toppling, flexural toppling, and planar sliding) contains 12 executable files which are run in series. The files for each scenario are as follows: - 1_scenario_setup_geom.uddat (e.g., 1_sliding_setup_geom.uddat): Creates block geometry - 2_scenario_setup_mesh.uddat: Creates mesh - 3_scenario_crack_mat1.uddat: Assigns initial joint strength and stiffness properties - 4_scenario_static1.uddat: Runs initial static equilibrium - 5_scenario_static2.uddat: Removes block to create valley and runs additional static equilibrium - 6_scenario_crack_mat2.uddat: Assigns effective joint strength and stiffness properties and runs model to static equilibrium - 7_scenario_fracture_state.uddat: Function to compute length of failed and open joints - 8_scenario_crack_mat3.uddat: Assigns high joint strength properties for dynamic simulations - 9_scenario_residual_stiffness.uddat: Assigns residual joint stiffness properties for dynamic simulations - 10_freefield.uddat: Applies freefield boundary conditions for dynamic simulations - 11a_dynamic_run.uddat: Runs dynamic model - 11b_dynamic_ref.uddat: Runs reference version (no dynamic input) of the dynamic model 2. Relationship between files: The files in Code.zip were used to run model simulations which produced the model outputs included in DynamicRuns.zip. 3.
