Different Types of Open Boundaries and When to Use Them
Understanding and effectively utilizing open boundaries is essential for accurate modeling and simulation in environmental and coastal engineering. Open boundaries, which dictate how a model interacts with its external environment, play a pivotal role in the EEMS model. This blog explores the various types of open boundaries supported by EEMS, each designed for specific purposes and scenarios.
From Elevation-Specified boundaries that control water surface levels to Incoming and Outgoing Wave Radiation boundaries that manage wave dynamics, and the distinction between Zero Tangential and Free Tangential conditions, this guide provides insights into their applications. Whether addressing tidal influences, wave reflections, or riverine inputs, understanding these boundary conditions enhances modeling accuracy and efficiency, ultimately leading to more reliable environmental assessments and effective coastal management strategies.?

In the News: Three-dimensional augmentation for hyperspectral image data of water quality: An Integrated approach using machine learning and numerical models
This research, led by Professor Dongil Seo and colleagues, presents a comprehensive methodology to enhance the utility of hyperspectral image data (HSD), with a specific focus on three-dimensional (3-D) augmentation of Chlorophyll-a (Chl-a). The study is structured into three key steps: (1) augmenting limited field water quality data by expanding time intervals and variables using neural network models, (2) generating 3-D data through numerical modeling, and (3) extending hyperspectral image data into 3-D representations using machine learning models.?
