Abstract
Floods are a major natural disaster worldwide. Flood control plans, risk mitigation programs,
and other forms of flood management techniques require a good understanding of the flood
risk situation and the possible implications for our community. The accuracy of the flood
damage estimates depends on both the modeling of the phenomenon and the risk assessment
of human systems exposed by the floods. This research work aimed to simulate floods and to
develop a subsequent flood damage assessment model based on inundation depths, velocities.
The study area lies between coordinates of 34°-03' to 34°-38' latitudes and 71°-28' to 71°-53'
longitudes. The main source of irrigation for the area is the Swat River. It flows through Kalam
valley up to Chakdara for 160 km and then Panjkora River joins at Qalangi. Finally, it flows
through the study area (District Charsadda) for the length of about 24 km (River reach of the
study area; also named as Swat river) and outfalls into Kabul river just a few km downstream
of Charsadda Bridge. In the past decades, swat valley experienced many disastrous floods
e.g., in the years 1973, 1992, 1996, 2005, and 2010, etc. Flood modeling was carried out using
ArcMap and HEC-RAS. The river geometry of the study reach was collected from the
hydrology department of Khyber Pakhtunkhwa Irrigation Department coupled with DEM of
1 m grid resolutions. This research has developed a maps for the geographical area around
Swat River in the Charsadda district. This final year design project majorly linked with two
SDGS goals: Goal 6 (Clean Water & Sanitation) & 15 (which states that our thesis on
"Hydraulics Modelling of Swat River" addresses SDG 6 by using hydraulic modeling to
improve water quality and manage floods, SDG 7 by evaluating hydropower potential and
integrating energy-efficient water management practices, and SDG 15 by addressing erosion,
sediment transport, and habitat preservation in the river basin.
