Water Level Prediction for Transportation Projects

The objective of this research project is to ensure proficient network management and safe usage of navigable waterways especially in waters that are subject to tides, it is essential that the height of the water at various tidal phases be known. Construction applications that require the knowledge of various tidal water levels include determination of bridge clearances and design of caissons, cofferdams, fenders and weep holes. For this study a Mean High Water (MHW) Manual will be developed that establishes a uniform New Jersey Department of Transportation (NJDOT) procedure for determining water level as applied to safety, construction projects, and bridge clearance determination in tidal areas. It will include an introduction to the phenomena of tides, and a detailed outline of an MHW study that consists of planning, observation sessions, data reductions, computations, and documentation of the established MHW. NJDOT consultants and in-house staff can use the manual as a general reference for work in areas subjected to tidal waters.
