Abstract

The changes in land use land cover have a strong effect on the runoff and peak discharge. It is important to analyze the flow data of any watershed to identify the peak discharge. There are several methods to analyze peak discharge. The hydrologic response of any watershed can be analyzed through the Unit Hydrograph. The main aim of the study is to analyze the effect of land use and land cover change on the ordinates of unit hydrograph of the Muvattupuzha sub-basin. The study period considered for analysis is 1998,2008, and 2018. The results from the study during the selected period show that the value of peak discharge is increasing. It is found that the increase in the population has a direct impact on the land use and land cover change which intern affects the value of peak discharge. A very strong positive correlation is obtained between the built-up area and the peak discharge.
