The boundary between water and land is one of the most ancient boundaries used by
society. Despite the long history of usage, society has found that the land/ sea zone is not a
definite boundary. The influences on a tidal boundary are many, from gravitational and
centrifugal forces acting on the earth to the many local variations that can shape a tide.
From this active interface between water and land, a surveyor must determine a precise
boundary. The aim of this project is to develop a system of procedures that will help to
define this dynamic boundary.
Developing a procedure manual will involve researching and evaluating the current
guidelines, regulations and survey techniques used in determining tidal boundaries. This
research will allow the development of a system that will guide a land surveyor when
determining Mean High Water Mark boundaries along tidal land. These guidelines will be
applied to a tidal boundary on the Central Coast of New South Wales, so as to validate the
This project has found that using tidal information collected over a long period of time at a
tide gauge would increase the accuracy of determining a tidal plane. By comparing the tidal
data of a site that does not have long term tidal data with a control gauge, which does have
long term tidal data, a reliable answer can be achieved. Therefore a procedure was
developed to guide a surveyor through the determination of a Mean High Water Mark
within New South Wales.
The procedure manual will introduce a system in the techniques to follow in determining a
water boundary. The user of the manual will be aware of the various issues faced in
establishing a tidal boundary and this manual will allow them to make the informative
decisions. It is recommended that this manual be incorporated into any survey company's
quality control management system.
