Modeling and Simulation of Measuring the Depth of the Sea Water using Laser

Abstract

Airborne LiDAR bathymetry (ALB) has emerged as a pivotal technology for the simultaneous acquisition of high-resolution morphological data spanning both coastal topography and benthic environments. Unlike conventional topographic LiDAR operating at the infrared spectrum (1064nm), bathymetric systems integrate a green laser wavelength (532nm) capable of penetrating the water column to resolve shallow benthic features. Driven by stringent environmental regulations and the escalating impacts of climate change—such as sea-level rise and severe fluvial flooding—the demand for precise shallow-water mapping has intensified globally. Efficient coastal zone management, marine hydrological research, and civil engineering infrastructure fundamentally rely on robust, high-fidelity bathymetric data. To address these critical needs, this research develops and simulates an advanced laser-matter interaction framework. This simulation is specifically designed to improve the accuracy of depth mapping and analysis across various shallow water bodies for geological and environmental analysis purposes. Wave and eddy conditions are taken into account, and an appropriate compensation function is derived to achieve optimal seabed mapping accuracy.
