Summary

The Indonesian capital city of Jakarta is a typical delta city suffering from regular riverine flooding, usually in the peak of the wet season (November to January). One of the causes is the still ongoing structural increase of the peak discharge intensity of the rivers crossing the city due to land use change in the upstream parts of the catchments, steep mountainous areas (±3000m +MSL) in the south of Java island. 

The Ciliwung is the largest of several rivers and the upstream part of the catchment, the Upper Ciliwung (160 km2) was used as study area. Many modelling studies already have shown the negative effect of land use change, especially deforestation, which led to increased peak discharges at the outlet of the Upper Ciliwung, the Katulampa weir, about 30 km south of the border of the city of Jakarta. So far modelling studies in the Upper Ciliwung were only done at low temporal resolution (day-month time step), much coarser than the timescale of observed rainfall-runoff processes in the study area.
