DRAINS Extension Workshop
This practical 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.
To attend this advanced workshop, it is expected that participants have completed the DRAINS Core Workshop or DRAINS Refresher Workshop.
Set up and configuration of ARR 2019 procedures is ASSUMED knowledge during this advanced style workshop. For participants not familiar with ARR 2019 it is recommended that they at least attend the ARR 2019 Morning Seminar presented as a separate seminar.Benjamin Kus and Hossein Ansari, and runs from 9 am until 5 pm, with 7 hours of tuition. The topics covered include:
- 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,
- Using the premium hydraulic model to simulate complex overland flows,
- Modelling recorded rainfall records and probable maximum precipitation,
- Property drainage practice and infill development problems,
- Simulating large catchment areas using the Storage Network Routing Module,
- Exploring the role of GIS and 2D flood modelling,
- Extracting data from DRAINS to use with 2D flood models,
- Modelling of a complex detention basin with diversion chamber and GPT pre-treatment.
- complex detention basins.
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 complex detention basins into models and to apply storage routing hydrological models.
Participants are provided with notes and a USB drive with PDF copies of the DRAINS manual and workshop notes, spreadsheets, examples, exercises and solutions, which can be utilised for post-workshop revision.
