Abstract

Erosion along the Cibeet River, particularly in the Cipayung area of Bekasi Regency, has caused severe riverbank degradation and poses risks to surrounding land use. To address this problem, groynes—structures intended to reduce flow velocity and deflect currents away from vulnerable banks—were assessed for their effectiveness. The study combined field surveys, hydrological modeling with HEC-HMS to estimate design flood discharge, and two-dimensional hydraulic simulations using HEC-RAS. A design discharge corresponding to a 50-year return period (1493.6 m3/s) was applied as the primary input. The results indicate that existing groynes provide limited effectiveness, reducing flow velocity by only 3% at the critical cross-section. In contrast, the proposed groyne configuration, designed according to SNI 2400.1:2016, achieved substantial improvements, with velocity reductions of 29% at cross-section CC and 20% and 19% at cross-sections BB and AA, respectively. Overall, the findings demonstrate that technically optimized groyne layouts can significantly enhance flow regulation, mitigate erosion, and contribute to more sustainable river management.
