Building a Calibrated Rainfall-Runoff Model with eWater Source


Overview

Source is a water quality and quantity modelling framework that supports decision-making and a whole-of-catchment management approach. It allows you to model the amounts of water and contaminants flowing through a catchment as a result of different climate and catchment scenarios.

It provides an interface for the input, manipulation, and output of flow and water resources related information, through the creation of models and scenarios.

This two-day course investigates working with spatial data as an input to define catchments, preparing and loading time series data, setting up rainfall-runoff models and calibration techniques within Source using automatic calibration tools. An introduction to Source basic concepts and user interface will be followed by a workshop on preparing data formats for Source, including the spatial data inputs. Users will then be taken through the various models available in Source, including rainfall runoff, constituent and filter models, and also be introduced to its customisation capabilities. Finally, we will explore calibration methods to complete the development cycle of building a catchment scenario in Source.

Course content

Attendees will learn how constructing catchment models and running simulations for a range of scenarios helps to assess the impacts of catchment management practices on water quantity and quality outcomes.

Day One

  1. A brief history of Source development.

Who should attend

This training is aimed at professionals (engineering and environmental) in local government, consultancies and waterway and catchment management agencies.

Hydrological modellers interested in creating calibrated base models from which to explore the effects of various changes in their catchments will benefit most from this course.

Why you should attend:

  • Address complex problems with modelling scenarios
  • Build on your calibration and data requirement knowledge
  • Complete parameter sensitivity and analysis tasks
  •  An opportunity to learn from leading catchment practitioners
  • Network with other catchment managers, and trade ideas and contact details.
