Abstract

This study investigates the impact of rip currents on abrasion at Kota Bani Beach, North Bengkulu Regency. Through direct field measurements of current velocity, wave height, beach slope, and drone photo visualization, we classify Kota Bani Beach as a steep shoreline with up to 18° slope. Significantly, the eroded zone experiences the highest rip current occurrence, featuring current velocities of 1.9 m/s and wave heights of 1.72 m. Our findings underscore the influence of rip currents on beach abrasion, with the eroded zone exhibiting a pronounced susceptibility to rip current occurrence compared to the non-eroded zone. This research highlights the critical role of rip currents in coastal erosion processes, offering valuable insights for coastal management and mitigation strategies. Highlight: Rip Current Impact: Investigating the influence of rip currents on abrasion at Kota Bani Beach reveals a significant connection between these currents and shoreline erosion. Erosion Hotspot: The eroded zone experiences the highest rip current occurrence, characterized by notable current velocities (1.9 m/s) and wave heights (1.72 m). Management Insights: This study underscores the critical role of rip currents in driving coastal erosion, providing essential insights for developing effective coastal management and mitigation strategies.

Abstract

Estuarine morphology is profoundly influenced by dynamic coastal processes, particularly the interplay of longshore currents and wave energy. This study delves into the evolving Selagan Jaya River estuary, characterized by changing mouth morphology attributed to siltation. Longshore currents and wave energy, stemming from coastal waters, play a pivotal role in this transformation. Employing field measurements encompassing current direction, speed, wave height, period, and drone-aided visualizations at five strategic points, a comprehensive analysis was conducted. Quantitative findings reveal wave heights ranging from 0.01 to 1.74 m, wave periods spanning 3 to 11 s, and current speeds oscillating between 0.1 to 1.1 m/s in a westerly direction. The outcomes unequivocally underscore the significant influence of longshore currents and wave energy on estuarine evolution, specifically in shaping the Selagan Jaya Estuary through sedimentation-induced siltation. These findings bear implications for coastal management and morphological preservation in estuarine environments worldwide. Highlight: Dynamic Influence: This study emphasizes the substantial impact of longshore currents and wave energy on the morphology of evolving estuarine systems. Changing Estuary Shape: The research focuses on the Selagan Jaya River estuary, illustrating how dynamic coastal processes, particularly sedimentation-driven siltation, contribute to alterations in mouth morphology. Comprehensive Analysis: Through field measurements and drone-assisted visualizations, the study provides quantitative insights into wave characteristics and current dynamics, revealing the intricate interplay driving estuarine transformation.

Abstract

Investigating the dynamic Air Rami Estuary in Mukomuko Regency, Bengkulu Province, this study explores the role of wind movement in shaping estuarine morphology. The research aims to discern wind speed and vector direction associated with estuarine changes. Employing field measurements, wind parameters, and estuary imagery from USGS, the investigation reveals wind speeds ranging from 1.630 to 5,210 m/s, averaging 3.153 m/s, predominantly oriented south and southwest. These findings underscore the profound impact of wind dynamics on Air Rami Estuary's shape alterations, advancing our understanding of coastal morphological evolution and resilience. Highlight: Estuarine Wind Dynamics: This study investigates how wind movement influences the morphological evolution of the Air Rami Estuary, shedding light on a crucial coastal process. Wind Speed and Direction: By analyzing wind parameters and vector direction, the research uncovers a range of wind speeds and prevailing orientations, revealing significant insights into estuarine changes. Resilience and Evolution: The findings emphasize the substantial impact of wind dynamics on shaping estuarine morphology, contributing to our broader understanding of coastal resilience and evolution.
