About this tender

Environment Canterbury is procuring a Request for Proposals for High Stage Rating Curve Modelling (reference SCI_2600812), run by its Science department. Rating curves convert recorded water level data to flow and are central to flood hazard management. The agency wants to develop a modelling approach to define rating curves for flows higher than it has gauged, and is open to innovative solutions that improve on its traditional approach of rating curve extrapolation. The scope requires models to be developed for three water level recorder sites. Each model must be calibrated to recent high-flow gaugings. Flows that produce the maximum possible water levels must then be run through each model to establish a high stage/flow relationship for each site. Expected duration and deliverable format are not stated on the page.
