+==Introduction==
Flooding is a major environmental and economic challenge, particularly in urban areas where impervious surfaces prevent natural infiltration. [[Climate change]] is increasing the frequency and intensity of extreme rainfall events, exacerbating flood risks. Flood mitigation strategies that incorporate Low Impact Development (LID), traditional stormwater management, and hybrid infrastructure can manage stormwater effectively and reduce flood impacts.

+==Types of Flooding==
+{|class="wikitable"
+|+ Types of Flooding
+|-
+!Pluvial (surface) flooding
+|
+*Caused by extreme rainfall exceeding soil infiltration and storm sewer capacity.
+*Common in urban areas with high impervious surface coverage.
+*Exacerbated by poor drainage and outdated stormwater infrastructure.
+|
+!Fluvial (riverine) flooding
+|
+*Occurs when rivers overflow their banks due to heavy rainfall or snowmelt.
+*Worsened by upstream land use changes that increase runoff.
