# Avalanche Scenario Model Chain – Configuration File
# ------------------------------------------------------------------------------
#
# Purpose :
#     Central configuration for the Avalanche Scenario Model Chain (Steps 00–15).
#     Controls all preprocessing, PRA generation, FlowPy simulation, and
#     AvaDirectory building through a unified parameter and workflow structure.
#
# Structure :
#     [MAIN]          Project metadata, paths, input rasters, and global settings
#     [WORKFLOW]      Step activation flags (PRA, FlowPy, AvaDirectory)
#     [pra*]          PRA delineation, filtering, segmentation, elevation/size
#     [avaPARAMETER]  FlowPy parameter generation (Step 09)
#     [avaSIZE]       Size back-mapping rules for FlowPy outputs (Step 11)
#     [avaDIRECTORY]  Avalanche Directory building and enrichment (Steps 13–15)
#     [PLOTS]         Optional visualization parameters
#
# Usage :
#     - For project-specific overrides create:
#           local_avaScenModelChainCfg.ini
