Drainage System Investigation
This advanced workshop concentrates on the analysis capabilities of DRAINS, applied to (a) the planning of new drainage systems, and (b) identifying problem locations within existing drainage systems, to alleviate flooding and facilitate new developments.
This workshop will be useful to Council engineers involved with development approvals, asset management and flood mitigation, and consultants working on subdivision design and infill design. Attendees should have completed the DRAINS Core Workshop, or have significant working experience of DRAINS.
Set up and configuration of ARR 2016 procedures is assumed knowledge from the DRAINS Core Workshop.
- The nature of investigation, and how it can be applied to urban stormwater drainage systems in both greenfield areas and established urban areas,
- A review of the analysis abilities of DRAINS, using an example of a new residential subdivision, considering almost all DRAINS components and highlighting the premium hydraulic model,
- Examples of (a) a new development combining piped and trunk drainage systems, and (b) analysis and remediation of an existing system,
- The use of storage routing models such as RORB and RAFTS for broad-scale modelling,
- Methods of modelling open channel systems in DRAINS,
- Exercises on developments in flood-affected areas, and
- The application of DRAINS to large-scale piped drainage systems to locate 'problem spots' and for modelling flood impacts and extents, to assess the efficiency of drainage system assets.
The workshop will provide participants with:
- an understanding of the complexities of modelling and analysing stormwater drainage systems, and the ability to devise solutions for developments in flood-affected areas,
- the skills to set up, run and interpret models of these in DRAINS, and
- knowledge of how to incorporate open channels, culverts and bridges into models and to apply storage routing models.
