h e r, C h e n rong oc­curr, an at­moch aroused nd brought ong Kong. menon could un­der the im­pact of cli­mate change, Chen said. “So it is im­por­tant to en­hance the ac­cu­racy of sea­sonal fore­cast­ing of heavy rain­fall in the dry sea­son so that the DSD can take all pre­cau­tions to mit­i­gate the im­pact of floods that pos­si­bly may oc­cur.”

While sci­en­tists are wrack­ing their brains to find ways to im­prove the ac­cu­racy of flood fore­cast­ing un­der the chang­ing cli­mate, there are ar­chi­tects who have ac­cepted the fu­ture un­cer­tainty and be­gun to make their own pro­jec­tions.

“Flood­ing is inevitable in the fu­ture. It is time to think how to adapt to it,” said Liao Kuei-hsien, as­sis­tant pro­fes­sor in the School of Ar­chi­tec­ture of the Chi­nese Univer­sity of Hong Kong, sug­gest­ing that the man­made sur­round­ings be de­signed to be flood­able and that more public space, es­pe­cially in ur­ban ar­eas, be multi-func­tional so it can be opened dur­ing rain­fall for storm-wa­ter stor­age.

Liao clar­i­fied the dif­fer­ences be­tween flood­ing, a nat­u­ral phe­nom­e­non, flood haz­ard, a po­ten­tial threat of flood­ing to hu­man be­ings, and flood disas­ter, which causes dam­age to res­i­dents and the econ­omy.

As the cur­rent flood con­trol sys­tems are in­suf­fi­cient to sus­tain fu­ture flood dis­as­ters, it is im­por­tant “to in­crease the re­silience of the city and to pre­vent flood haz­ards from be­com­ing flood dis­as­ters”, Liao said, ex­plain­ing that re­silience means a city in flood re­cov­ers quickly and con­tin­ues to op­er­ate nor­mally.

“We’ ll be liv­ing in an en­vi­ron­ment where flood­ing is nat­u­ral. So we need to get used to it. Just let it flood,” she said, an­tic­i­pat­ing an en­vi­ron­ment which adapts to floods.
