Impacts of Climate and Land-Use Change on Runoff (Case Study: Balighloo Chai Basin, Iran)
B. Farokhzadeh, S. Choobeh, and H. Nouri
Abstract—Global climate changes due to increased
greenhouse gases and changes in land use such as urbanization
pose challenges for conservation strategies. In this research to
assessment the effects of climate changes in Balighloo Chai
basin, during the 2050s, A2 and B1 scenarios were downscaled
with LARS-WG and were compared with the 1983-2013 period.
Results showed the increase between -0.47 to 3.09 percent in
average annual rainfall and the increase between 1.80 to 2.02 °C
in average temperature in the 2050s. Two land use scenarios
were developed to predict the impact of land use changes on the
runoff in the coming decades: in the first scenario the current
land use assumed fixed and unchangeable in future and in the
second scenario assumed the same trend of changes which has
occurred in the past (continuation of the past changes) . Results
show a decrease of 41 percent in rangelands area and 21 percent
increase in agricultural area to 2050s. In order to simulate the
hydrologic system in the coming decades, HEC-HMS model
calibrated and validated using real data. Results showed
increase of peak flow and flood volume in April and decrease of
peak flow and flood volume in March, May, and June. If land
use change occurs with climate change, this changes will be
intensified.
