Pakistan is a flood-prone country with a history of widespread and repeated flooding that causes loss of lives, substantial damage to property, infrastructure, loss of agricultural crops and land (Sardar et al., 2008). It has two dominant types of floods i.e. riverine and flash. The riverine flood, mainly originating from glacier melt as well as extreme weather events, is predictable which in result allows sufficient time to react whereas the converse is true for flash floods. Flash floods, originating from extreme weather events, have relatively less duration but intensity and impacts are severe. These floods normally occur during the South Asian monsoon period between July and September.
