Stormwater control and management road map to 2055 Sustainable Development and Natural Resources

Stormwater management status quo Why stormwater management?

Water cycle Before Humans (B.H.)

Water cycle After Humans (A.H.)

Stormwater management status quo Why stormwater management? Current practice

Interventions Impermeable roads Kerbs, inlets, and storm sewers High energy outlets onto floodplanes, wetlands, and estuaries Channelisation of natural waterways

Effects of urbanization Increased run-off volumes Increased run-off concentrations Flooding and damage to property Decreased natural infiltration Lower water table Increased temperature in natural streams Increased pollution
