Mod­els of flood man­age­ment

Down to Earth - - COVER STORY -

TORONTO AND Re­gion Con­ser­va­tion Flood Man­age­ment Pro­gramme of Canada is con­sid­ered a model for flood man­age­ment in ur­ban spa­ces. In prac­tice since 2011, the pro­gramme forms a close link be­tween Canada's Weather Of­fice, Min­istry of Nat­u­ral Re­sources and lo­cal gov­ern­ment agen­cies of the four sub­di­vi­sions of Toronto—Durham, Peel, Toronto and York. One of the ma­jor tasks un­der­taken is clear and con­sis­tent flood warn­ing. Lo­calised warn­ings help the au­thor­i­ties to con­vince peo­ple to move to se­cured lo­ca­tions. One ma­jor prob­lem that the au­thor­i­ties in Kashmir faced was the in­abil­ity to con­vince peo­ple of the se­ri­ous­ness of the sit­u­a­tion and the need to move to safer places.

The three de­part­ments also iden­tify flood-prone ar­eas and un­der­take mit­i­ga­tion mea­sures to re­duce risk. In terms of in­fra­struc­ture, the Toronto and Re­gion Con­ser­va­tion Au­thor­ity is man­dated to op­er­ate and main­tain flood con­trol in­fra­struc­ture across all re­gions of Toronto, in­clud­ing large dams, chan­nels, flood walls and dykes.

Ari­zona, a south-western state of the United States, has gone a step ahead to re­tain the wa­ter qual­ity after floods. The Flood Con­trol Dis­trict is a plan to con­trol flood­ing in Mari­copa County, the worst-af­fected re­gion of Ari­zona. The plan is be­ing car­ried out as per the Na­tional Pol­lu­tant Dis­charge Elim­i­na­tion Sys­tem Stormwa­ter Pro­gramme as part of the Clean Wa­ter Act. A guide and aware­ness man­ual has been cir­cu­lated among the pub­lic and lo­cal au­thor­i­ties on ways to pre­vent flood­wa­ter from en­ter­ing into the wa­ter chan­nels of the area.
