Hydrodynamic and Boussinesq Wave Modeling for the N219 Amphibious Aircraft Seaplane Dock Development Plan in Panjang Island

Abstract

The flight test of N219 Amphibious aircraft will be targeted in 2003/2024. For flight tests, these aircraft need a seaplane dock. One of the potential locations for the seaplane dock is Panjang Island at Seribu Islands. This study aims to know the characteristic of hydrodynamic and wave conditions and to determine whether Panjang Island is suitable for the seaplane dock. This study uses a modeling method with MIKE 21 FM HD-SW module and MIKE 21 Boussinesq Wave (BW) module. The bathymetry data were obtained from the Indonesian Navy Hydrographic and Oceanographic Center (Pushidrosal), tide data is generated from Tide Model Driver (TMD), wave and wind data from ECMWF. The result of surface elevation validation between hydrodynamic modeling and TMD is 92%. During the west monsoon and spring conditions, the difference in the largest and lowest current velocity is quite large (0.018-0.199 m/s), on the other hand, when the tides are in neap conditions (0.008-0.144 m/s). Meanwhile, during the east monsoon and spring conditions, the difference in the largest and lowest current velocities is quite large (0.02-0.193 m/s), on the other hand, when the tides are in neap conditions (0.008-0.146 m/s). The maximum wave height resulting from the 50-year return period waveform modeling between 1.139 - 1.474 m. Meanwhile, the significant wave heights between 0.679 - 0.741 with a significant wave period of 13.45 seconds. In general, the current and wave conditions of the two locations are suitable for the construction of the seaplane dock, except that the dominant wave heights are still above the requirements.

Numerical modeling of return period waves based on non-linear Boussinesq wave models to support tidal flood studies in the Kedungsepur area

“…The role of the BW-type model has been reported by [22] when simulating wave propagation in Panjang Island incorporating manning variations between 10 and 32 m 1/3 s -1 . In their study, it is suggested to utilize a combination of hydro, wave, and littoral transport/sedimentation models to assess the possibility of changes in the site's bed level and bathymetry before running the BW model.…”

“…Based on the modeling results, the validation value between the tidal driver model (TMD) data and MIKE 21 HD is 92 %. Thermal dispersion modeling has also been carried out around the Muara Karang PLTU using three-dimensional MIKE 3 Flow Model Flexible Mesh (Khoirunnisa et al, 2021b). Based on research conducted by Saputra (2018), the current velocity in the master plan condition is smaller than the post-reclamation condition; this is due to the deflection of the current in the reclamation island (Saputra, 2018).…”
