Research gap
Identified Research Gaps
Much existing literature on Chinese urban flooding in science and engineering perspective
Dearth of knowledge on Urban flooding and
Sponge cities
No studies found within expert perspective
To fill this research gap………..

Methodology
Current study has taken the expert views
A Piolet study was conducted during the R&I conference (n = 17)
Experts have the knowledge on
Chinese urban flooding and sponge cities concept
All experts have > 10 -20 years experience
All are working at different organisations in various capacities
(Such as Professor, Associate Prof; Senior Lecturer)
Click to edit Master title style
Methodology
Questionnaire which contain four questions have been
distributed to the participants ( 32)
Only 21 members have been returned their answer sheets
In those, 4 members offered unclear
and controversial answers
Only 17 experts views have been taken for analysis

Results
The majority stated that sponge cities are an
excellent concept, but that capturing and storing
rainwater is somewhat difficult
Very few experts opposed this concept (2 members) and
these experts also expressed that – sponge cities concept is not a useful to the mega cities like Beijing

Conclusion
Expert opinions should be used as tools for planners and
policymakers for developing management strategies to
improve urban resilience under the scenarios of climate
change and anthropogenic pressures
