CROSS SECTION SURVEYS

I WANT TO DESIGN A PIER, KNOW WHERE THE BOATS CAN PASS, KNOW WHERE THE DROP OFF POINTS OR WHERE THE CORALS REEFS ARE ALONG THE SHORELINE

The client practices free diving and would like to know where the drop off points are at Vistamar Beach Resort in order to plan their dives.

Philsurv used sonar and GPS technology to produce a hydrographic map. At the same time, the sonar data was able to identify where the coral reefs location in the area

HOW IS IT USEFUL ?

• Study of wave heights, sudden changes in water depths, uncharted reefs, currents, tidal streams, seaweed and mobile beaches (sand drift)

• Avoid shelters fouling up with seaweed or silting up (shelter mouth facing the wrong direction) or just being inaccessible in rough weather (reefs too close to entrance channel)

• Correct design decisions upon project inception stage to ensure that the landing is easy to use and free of major maintenance problems under all conditions

• Thematic maps showing where coral reefs are
