Abstract

Land use change in the upstream, middle and downstream of Cimandiri River caused changes in runoff coefficient and also flood discharge in the downstream of Cimandiri River. The type of research conducted was descriptive quantitative. Changes in land use that occurred in 2011-2022 in the Cimandiri watershed are for dry land agriculture (-85.68%), Mixed Dry Land Agriculture (-12.36%), Rice Fields (-13.49%), Shrubs / Bushes (-97.11%), Open Land (-66.04%), and Water bodies (-5.51%). And there is an increase in land use in Settlement areas (51.31%), Plantation (30.07%), Industrial Plantation Forest (HTI) (265.51%), Secondary Dryland Forest (7.39%), and Primary Dryland Forest (3.07%). Changes in land use resulted in changes in the runoff coefficient (C) in 2011 of 0.13, in 2017 of 0.14, and in 2019 of 0.13. thus it affects the design flood discharge in the 25-year return period in 2017 of 469.80 m3/sec.
