ABSTRACT 
Flood as one of the most destructive natural hazards causes huge damages every year all around the world. Land 
use change acts as one of major reasons of flood generation. Main objective of this research is investigation on 
flooding status of Pol-Doab Shazand sub-catchments due to land use changes and their prioritization using 
rainfall-runoff data. The prioritization results can be helpful to allocate proper flood control measures over 
critical flooding areas. To identify land use changes, land use maps of years 1973 and 2008 were created using 
MSS and LISS III data. Then to simulate design discharge, HEC-HMS model was applied and run in event-
based format. After simulation of design discharge with different return periods, the best design discharge with 
the most appropriate return period was chosen using factor analysis method. The result is applied to evaluate 
and prioritize sub-catchments. The results showed that 25 years return period discharge is suitable to do analysis 
of flooding status of sub-catchments. The results also indicated that land use has clear impact in flooding events 
with smaller return periods.
