Cross Section Profiles
Cross Section Profiles
Engineers, designers, project managers and builders understand the importance of ‘as built profiles’. In a design and engineering project where errors and flaws must be recognised immediately to mitigate disaster there is no room for guess work.
Total Hydrographic can provide cross section profiles to check that rock walls, groynes, channel batters and other structures have been built to the correct design specifications. This is done by comparing the surveyed surface against the design model and observing the data from a cross sectional profile perspective.
Cross section profiles are a cost-effective method of acquiring survey data. If you are only surveying designated cross section profile lines instead of the entire water body the quantity of data required is drastically reduced. By surveying at regular intervals, we can help build an understanding on how the water body changes over time.
Cross Sections Profiles can be useful for:
- Beach Profiling – sand is a dynamic material making it difficult and expensive to survey the entire beach surface. Regular cross section profiling can establish an accurate model and accurate volumes of sand movement can be calculated.
- River Profiling – reducing survey costs for flood modelling along rivers.
- Breakwater Profiles – comparing the construction of a breakwater to its design model and then providing ongoing monitoring to ensure the breakwater’s integrity is maintained.
- Channel Profiles – comparing the dredged surface to the channel design surface and ongoing monitoring of sediment accumulation.
More About Beach Profiling
Cross section profiling is particularly useful for surveying large areas. Beach profiling is an example of where cross sections can be used effectively. The sand on the beach is a dynamic material. This makes it difficult and expensive to regularly survey the entire beach surface to monitor the movement of the sand.
However, if cross section profiles are performed regularly (i.e. every 3 months) we can significantly reduce the survey costs while still allowing the beach material movements to be monitored. An accurate model is built up and volumes of sand movement can be calculated.
Total Hydrographic’s cross section profile surveys are conducted exclusively by professionally recognised Level 1 and Level 2 Certified Hydrographic Surveyors, assessed by the Australasian Hydrographic Surveyors Certification Panel (AHSCP) through the Surveying & Spatial Sciences Institute.
