Surveys for shoreline monitoring programme
Chee Hai, Teo
Malaysia has a shoreline of over 4,000 kilometres and certain portions of this shoreline that are being eroded needed engineering measures to protect the shoreline and in certain instances these measures included beach nourishment works. Effective engineering measures require careful study including hydraulic studies of the coastal regime and engineering design alternatives. In certain instances, environmental impact assessment is also required. Invariably the need to identify this land/sea interface is crucial. Such studies and assessment must be based on a proper spatial dataset for the targeted coastal areas. The provision of this dataset for initial studies, assessment and design is the role and responsibility of Surveyors. However, the Surveyors role does not end with the provision of the initial spatial dataset. One of the measures to monitor the impact of such coastal engineering works is the implementation of a shoreline-monitoring programme for each coastal engineering works. This programme included initial or baseline survey, shoreline monitoring survey during construction works and thereafter for a further period of at least two years. Typically, the Surveyors involvement in projects of this nature could span three to five years. This presentation will discuss the typical scope for the topographic and bathymetric profiling for shoreline monitoring programme for a typical coastal engineering works, the basic instrumentation and methodology employed to ensure that the survey is fit-for-purposee as implementers of these works have to be cost conscious.
