AutoRamtin automates HEC-RAS simulation workflows, reducing repetitive manual setup and execution tasks.
It supports Monte Carlo analysis for uncertainty assessment.
It enables parallel run of multiple HEC-RAS plans.
It facilitates the systematic export and organisation of simulation outputs.
AutoRamtin is a Python-based graphical automation tool for HEC-RAS 2D unsteady-flow modelling, designed to simplify repeated simulation workflows and reduce manual file handling. It provides two main execution modes: the Monte Carlo option and the Parallel Plans option. In Monte Carlo mode, a base HEC-RAS plan can be selected to generate multiple simulation realisations by automatically varying inputs such as Manning’s n values and hydrograph peak factors using Uniform, Normal, or Lognormal distributions, with either box or tapered hydrograph scaling. In Parallel Plans mode, multiple existing HEC-RAS plans can be selected and run concurrently using a defined number of parallel simulations, allowing faster comparison of different scenarios, boundary conditions, or numerical settings. After execution, AutoRamtin extracts and organises key outputs, including maximum water surface elevation, maximum water depth at selected cells, and flow at selected reference lines, storing the results systematically in timestamped output folders for easier analysis, comparison, and reporting.
