Numerical Model Applicability Based on a Hydraulic Characteristic Analysis of an Eco-friendly Double-row Submerged Breakwater

Yeon-Myeong Jeong, Jaeheon Jeong, Taegun Park, Ho-Seong Jeon, Dong-Soo Hur

J. Ocean Eng. Technol.. 2024;38(4):164-173.

In this study, a submerged breakwater with effective wave control and eco-friendly characteristics is developed and proposed. Hydraulic experiments are conducted to compare the hydraulic performance of a submerged breakwater and an eco-friendly double-row submerged breakwater. The hydraulic characteristics are analyzed based on wave reflections and the transmission-splitting method for...

GCP Placement Methods for Improving the Accuracy of Shoreline Extraction in Coastal Video Monitoring

Changyul Lee, Kideok Do, Inho Kim, Sungyeol Chang

J. Ocean Eng. Technol.. 2024;38(4):174-186.

In coastal video monitoring, the direct linear transform (DLT) method with ground control points (GCPs) is commonly used for geo-rectification. However, current practices often overlook the impact of GCP quantity, arrangement, and the geographical characteristics of beaches. To address this, we designed scenarios at Chuam Beach to evaluate how factors...

OGM-Based Real-Time Obstacle Detection and Avoidance Using a Multi-beam Forward Looking Sonar

Han-Sol Jin, Hyungjoo Kang, Min-Gyu Kim, Mun-Jik Lee, Ji-Hong Li

J. Ocean Eng. Technol.. 2024;38(4):187-198.

Autonomous underwater vehicles (AUVs) have a limited bandwidth for real-time communication, limiting rapid responses to unexpected obstacles. This study addressed how AUVs can navigate to a target without a pre-existing obstacle map by generating one in real-time and avoiding obstacles. This paper proposes using forward-looking sonar with an occupancy grid...
