LTS Workflows

Setting up and running LTS simulations is a modelling task that requires a thorough understanding of the LTS concepts and solid modelling skills. The following descriptions of the complete workflows and advices on individual steps complement the technical information provided in the previous chapters.

A typical LTS workflow includes the following steps:

• Preparation of an LTS model setup
  • Set-up and calibration of a collection system model (catchments + network)
  • Choice of the simulation period, preparation of the LTS catchment boundary time series and definition of the LTS catchment model boundary condition
  • Definition of job list criteria
  • Definition of runtime stop criteria (optional)
  • Preparation of hot start files and definition of initial conditions for LTS simulation events (optional)
  • Review and modification (optional) of LTS global parameters
  • Definition of LTS outputs
    • "Standard" result outputs
    • Extreme event statistics (instantaneous and accumulated)
    • Chronological statistics (monthly and yearly)
    • Continuous TS outputs
• Setting-up and execution of an LTS simulation
  • Set-up and execution of the catchment model simulation (runoff and catchment discharge)
  • Creating a job list
  • Set-up and execution of the network LTS simulation
• Review, analysis and presentation of LTS results.

The steps in the LTS workflow are described in the following chapters.
