FLOATING ICE THICKNESS AND STRUCTURE DETERMINATION -- HEATED WIRE TECHNIQUE

R. O. Ramseier Robert J. Weaver

The thickness of floating ice is the important parameter to be measured for many applications in the fields of transportation, engineering and climatology. The requirement for accurate thickness information, with details on the ice structure, led to the development and use of the heated wire ice thickness gage. Once installed, the gage provides a means of making in-situ thickness measurements on fresh and salt water ice quickly and accurately. This report describes the measurement methods of determining ice structure from readings obtained, and details of construction of the gage complete with engineering drawings.

Ensemble Neural Networks for the Development of Storm Surge Flood Modeling: A Comprehensive Review

Journal of Marine Science and Engineering (2023)

Saeid Khaksari Nezhad Mohammad Barooni Deniz Velioglu Sogut Robert J. Weaver

This review paper focuses on the use of ensemble neural networks (ENN) in the development of storm surge flood models. Storm surges are a major concern in coastal regions, and accurate flood modeling is essential for effective disaster management. Neural network (NN) ensembles have shown great potential in improving the accuracy and reliability of such models. This paper presents an overview of the latest research on the application of NNs in storm surge flood modeling and covers the principles and concepts of ENNs, various ensemble architectures, the main challenges associated with NN ensemble algorithms, and their potential benefits in improving flood forecasting accuracy. The main part of this paper pertains to the techniques used to combine a mixed set of predictions from multiple NN models. The combination of these models can lead to improved accuracy, robustness, and generalization performance compared to using a single model. However, generating neural network ensembles also requires careful consideration of the trade-offs between model diversity, model complexity, and computational resources. The ensemble must balance these factors to achieve the best performance. The insights presented in this review paper are particularly relevant for researchers and practitioners working in coastal regions where accurate storm surge flood modeling is critical.

Simulating Tidal Flushing Response to the Construction of a Low-Crested Weir Connecting Port Canaveral to the Banana River, Florida

Journal of Waterway Port Coastal and Ocean Engineering (2016)

Atousa Saberi Robert J. Weaver

Indian River Lagoon (IRL) is a restricted estuary along the east coast of Florida. Although Banana River, a 50-km-long subbasin of IRL, has an outlet to the ocean through the Port Canaveral Locks, the locks remain closed when there is no passing vessel, resulting in limited circulation, long flushing time, and poor water quality. The purpose of this study was to determine the extent to which constructing a low-crested weir adjacent to Port Canaveral can improve flushing in this region. A computer program was used to simulate the hydrodynamic properties of the study area and determine the two-dimensional (2D) depth-averaged velocity field. Then, passive particles were placed in the Banana River, and their movement was tracked using the Lagrangian particle-tracking model (LPTM). Transport timescales were then computed. Results indicate an improvement in flushing in both the Banana River and the central IRL. In the portion of the Banana River to the south of the port complex, the flushing time was decreased from over 200 days down to 38 days as a result of an induced southerly current caused by the proposed low-crested weir.

Wind-Driven Circulation in a Shallow Microtidal Estuary: The Indian River Lagoon

Journal of Coastal Research (2016)

Robert J. Weaver J. Emmanuel Johnson Morgan Ridler

Weaver, R.J.; Johnson, J.E., and Ridler, M., 2016. Wind-driven circulation in a shallow microtidal estuary: The Indian River Lagoon. Studying wind-driven fluctuations in the surface elevation along the Indian River Lagoon (IRL) allows researchers to better understand the best methods for managing sustainable water quality in a microtidal estuary. Water quality has a direct effect not only on the marine life, but also on tourism. This study improves the knowledge of circulation and surge in a shallow, microtidal estuary while enabling validation of numerical modeling efforts. Two submersible pressure sensors were deployed in the IRL for 7 months. Data collected from these gauges is analyzed in conjunction with data from permanent gauges at Haulover Canal and Sebastian Inlet, with an emphasis placed on the relationship between surface elevation and meteorological forcing. A time series analysis was employed to correlate periods of harmonic oscillations with wind events. Analysis focused on the direction of the wind with respect to the along-estuary and cross-estuary orientation of the lagoon. Results indicate that the water rises or falls uniformly in the cross-estuary direction and is transported to the south during Nor'easter events, piling up at the constriction south of Sebastian Inlet. Study results will be used to provide a better understanding of circulation in shallow-water estuaries, as well as improve numerical models to better predict wind-driven circulation in the IRL.
