BATHYMETRIC SURVEY OF RIVER SUIR CATCHMENT AREA

Key Facts:

Client: Office of Public works
Sector: Hydrographic
Value: 33K
Survey Type: Topographic Survey, Bathymetric Survey
Area: In excess of 215 sections
Resources: GPS, Total Station & Full Bathymetric survey equipment
Project Duration: 6 Weeks

Client Requirements: The contract required the survey of approximately 215 Channel and Structures cross sections within the catchment and a depth survey of two small lakes. The survey data was required to fill-in gaps in the existing survey data held by the OPW and consequently the required cross sections were spread throughout the catchment.

Murphy Surveys Solution: Due to the varying nature of requirements a combination of survey methods were utilised to capture the necessary information, this included

- Leica total station to capture detail on structures and in cases where GPS coverage was unattainable
- GPS RTK for channel inverts in open sky areas
- A combination of, total station, GPS and bathymetric survey to complete difficult areas
- Deliverables include AutoCAD drawings of location plans, cross sections, long sections, ISIS, Mike, Hecras, CSV and reports

A number of crews were deployed to different areas so that the deadline would be adhered to which required careful planning and logistics.
