MULLASSERY CANAL FRAMEWORK AND CANAL EDGE MASTERPLAN
designed to temporarily hold and delay the rain water. These are then safely conveyed to existing/proposed storm water drains thus reducing the run-off volume and increasing the lag time. Also during storm events accompanied by high tides, when the efficiency of existing drain is highly reduced, these inserted blue green infrastructure play an important role in assisting the existing storm water channels to mitigate flood and reduce property damage. 2.1.7 Scenarios: How the Blue Green Infrastructure in integration to Grey infrastructure plays out during different rain events throughout the year:
