Abstract

Buis Beton (Precast concrete pipe) revetment is a common coastal structure to protect the shoreline from erosion. However, it is common that this type of structure face high wave run up. A continuous wave run up on the slope of the structure may reduce the life service of Buis Beton revetment. The objective of this research is to create scientific based guidance to design an efficient Buis Beton revetment against wave run up. A physical modelling test is conducted to understand the relationship between wave run up and Buis Beton revetment. The test scenario is based on the slope of the structure (θ), structure height (L), buis beton diameter (φ), incoming wave height (Hi) and wave period (T). The physical modelling is conducted in 2D wave flume with laboratory scale of 1:10 with regular wave simulation. Wave run up is observed using a video camera which is later processed digitally to acquire the wave run up data. This research shows that the relative wave run up has a reciprocal functional relationship with the Iribarren Number parameter. In general, wave run up height on Buis Beton revetment is less than or equal to 2.64 the wave height, Hm0.Keywords: Revetment, buis beton, wave run-up, physical modelling

Abstract

                NCICD (National Capital Integrated Coastal Development) Seawall is designed mainly to prevent coastal flooding due to sea level rise and land subsidence in North Jakarta. However, the seawall is not designed to countermeasure a tsunami impact. The purpose of this research is to calculate tsunami impact in term of run-up in five strategic points such as Pelabuhan Muara Angke, Pelabuhan Nizam Zachman, Pantai Ancol, Pelabuhan Tanjung Priok dan Pantai Marunda. In this research, the seawall is evaluated for the worst-case tsunami scenario within the order of Tsunami Krakatau 1883. The source of tsunami is the initial condition from Maeno and Imamura (2011). The propagation from source to coastal area is conducted using SWASH model. SWASH 2D model shows a good agreement with observation data. Compared to Maeno and Imamura’s model, the numerical model shows a better agreement. The verified model is then extracted and the time series is used as an input for the 1D model to calculate the tsunami run-up. The model result shows that Tanjung Priok and Pantai Muranda are the most vulnerable point with tsunami run-up about 4 m. However, the current designed seawall with 4.8 m height is still sufficient to deal with this impact.

Abstract

The increased volcanic activity of Mount Anak Krakatau has raised the awareness of the potential tsunami impact for the construction of National Capital Integrated Coastal Development (NCICD) Project. This research is aimed to evaluate the tsunami impact on the outer sea dike of NCICD. The 1883 Krakatau tsunami was used as reference to evaluate the coastal infrastructure. Time series data from the 1883 Krakatau tsunami is extracted as an input to calculate the wave force. There are three different methods used such as Rule of Thumb (wave force is twice that of hydrostatic force), Linear Theory, Sainflou method. The results show that the tsunami will hit the outer sea dike with at least force about 70 kN. The outer sea dike OSD-1A is the least impacted sea dike while OSD-3A is the most impacted. For OSD-1A, Rule of Thumb and Linear Theory estimate 303.30 kN of wave force while Sainflou method predicts only 73.45 kN. On the other hand, OSD-3A endured wave force of 131.91 kN (Sainflou method) or 531.91 kN (Rule of Thumb and Linear Theory). Sainflou method is for efficient design while the other methods have the benefit of safety factor
