Knox City Council Urban Mapping

Knox City Council Urban Mapping

Water Technology urban drainage engineers has recently been appointed by Knox City Council to undertake the flood mapping of four of its urban catchments. The hydrological and hydraulic modelling will be completed in TUFLOW via a rainfall on grid methodology. Of the four catchments there is one which encompasses both urban residential areas and steep non-urbanised sections of the Dandenong Ranges which will be modelled using the multi-domain functionalities within TUFLOW.

The project will look at existing conditions, as well as mitigation scenarios which use a whole of water cycle management (WoWCM) approach to ensure the most optimal integrated stormwater management  solutions are reached. An example of this is the Water Sensitive Urban Design (WSUD) features within the Boronia Retarding Basin which are currently being constructed.

At this point Water Technology has undertaken preliminary 2D modelling, with the results used to determine points of interest and potential flooding hotspots within each of the four catchments. This information was subsequently used to inform the site visit which Water Technology and Knox City Council representatives undertook together. During this, invaluable local knowledge was conveyed from the Council staff which will significantly influence the outcomes of the study.

Knox City Council are currently surveying their drainage network which will ensure that the most up to date and accurate pit and pipe data will be available for the flood modelling of this study and any future flood mapping projects.
