• Abstract:
  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. This knowledge is also ; essential for property ownership determination and for construction projects in areas that are subjected to tidal waters. ; Construction applications that require the knowledge of various tidal water levels include determination and ; implementation of bridge clearances, design of caissons, cofferdams, fenders, and weep holes. Bridge clearances are ; calculated from tide observations, tide predictions and an assessment of the size of vessels expected to travel beneath ; them. Additional considerations that are to be addressed during bridge construction are minimum underclearances ; necessary to operate construction equipment, the season of construction and its effect on the water level, regulatory ; requirements of agencies such as the US Coast Guard, etc. ; Water levels and clearances are expressed in terms of elevations in a particular height system. To avoid ; implementation errors, it is essential that proper research, analysis, methods and procedures be exercised prior to ; construction to ensure that a consistent height system is being used. Insufficient determination of the current water ; levels and misunderstanding of height systems could become a public safety problem and/or result in property damage ; or damage to the integrity of the transportation network. ; The objective of this manual is to establish a uniform NJDOT procedure for determining water level as applied ; to safety, construction projects, and bridge clearances determination in tidal areas. It includes an introduction to the ; phenomena of tides, discussions on tidal and vertical datum, legal issues of tides, and methods for establishing the ; mean high water (MHW) at a construction site. The manual includes a detailed outline of a MHW study that consists of ; planning, observation sessions, data reductions, computations, quality assessment of the established MHW and ; documentation of the established MHW.
