Abstract

Tugu Air Bangis Beach, located in West Pasaman Regency, has experienced severe coastal erosion caused by wave energy from the Indian Ocean. This condition has resulted in the collapse of several structures along the shoreline and threatens the remaining coastal infrastructure. Mitigation measures are therefore required to maintain shoreline stability and prevent further damage. This study aims to design the layout of coastal protection structures for Tugu Air Bangis Beach using numerical simulations to reduce the impact of wave- and current-induced erosion. The data used in this study include satellite imagery, wind data, tidal elevation data, Digital Elevation Model (DEM) data, and aerial photographs. Tidal flooding (rob) occurred in Padang City and Air Bangis from December 3 to 5, 2021, and the tidal elevation data used for the simulation were obtained from real-time measurements recorded at the Teluk Bayur Station, Padang, between December 1 and 9, 2021. Numerical simulations were performed using the CMS-Wave and CMS-Flow modules in the Surface Water Modelling System (SMS) version 10.1. The simulations were conducted in two stages. The first stage employed the existing structure layout, simulated for 216 hours of model time (equivalent to 36 hours of computer running time). The results indicated that the incoming waves approach the shoreline perpendicularly, suggesting that a breakwater is the most appropriate coastal protection structure. In the second stage, two breakwaters of equal length (200 meters each) and equal distance from the original shoreline (100 meters) were added. The numerical model results showed that this configuration effectively mitigates erosion, as indicated by sediment accumulation along several shoreline segments and the initial formation of a tombolo behind the breakwaters.

Abstract

Conversion of catch-land into residential land in urban areas reduces infiltration, and increases surface flow and flood risk. Artificial infiltration is a potential solution to increase infiltration capacity, but its effectiveness is highly dependent on the physical characteristics of the soil, including geophysical constants. This study aims to determine the level of infiltration capacity based on the value of soil geophysical constants using artificial infiltration in residential land in Padang. Measurements were carried out using the Horton method and double-ring infiltrometer in several residential locations. The study results show that the soil characteristics of residential land in Padang consist of the soil texture of sand, loamy sand, and sandy loam, which have high moisture content, large fill weight, and low porosity, causing low infiltration rate and high surface flow. Artificial infiltration can significantly increase the infiltration capacity, especially on sandy soils with high hydraulic conductivity. The soil geophysical constant, k, is classified according to field measurement results. In the lower range of 1.2 < k ≤ 1.9, the average infiltration capacity was found at 625.1 mm/hour. Within the interval of 1.9 < k ≤ 2.6, the mean capacity decreased to 587.7 mm/hour, but in the upper interval of 2.6 < k ≤ 3.3, the average infiltration capacity was 499 mm/hour. Large soil geophysical constants reveal higher infiltration capacity, while small geophysical constants indicate low infiltration capacity.
