This document summarizes a case study on the location choice for Water Sensitive Urban Design (WSUD) in Melbourne, Australia. It discusses factors like slope, natural waterways, urban form, and socio-demographic variables that influence where WSUD systems like ponds, wetlands, swales and raingardens should be placed. The study analyzed the exact locations of existing WSUD systems versus random locations, and used spatial data and tools to understand relationships between placement and variables in order to develop better WSUD placement strategies and planning support tools.

WHERE DO WE PLACE THEM?
 Database completion
 Data cleaning
 Data collection for independent variables:
 biophysical
 urban form
 socio-demographic
 Two types of analysis:
 Exact WSUD location vs random location
 Geographic aggregation unit using RW
