Pumping station performance modelling using HEC-RAS API

One of our completed Research and Development (R&D) projects devised a quick, affordable method to enable our clients (e.g. IDB’s who may have many tens or even hundreds of pumping stations) to prioritise which assets to upgrade. This would then have an improvement on operational efficiency and reduce running costs and carbon emissions.

Background

HEC-RAS models have typically been used to simulate flood flows and resulting flood extents at most pumped sites. It was believed, but untested, that the models could be re-used as the basis for efficiency calculations.

Outputs

  • A methodology to derive appropriate ‘non-flood’ conditions for each site, as boundaries to the hydraulic model.
  • A spreadsheet-based Application Programming Interface (API) for HEC-RAS. This currently demonstrates multiple steps in the automation process. It can automate updates to model boundaries, run the model, extract results and undertake some post-processing of results. This has wider applications then pumping station analysis and could also be used to support anyone undertaking updates, or performing multiple design runs (different return periods, options testing and optimising elements within the model) using HEC-RAS.

The HEC-RAS API has huge potential to support other projects using HEC-RAS models.
