Near Shore and Riverbed Profiling System

The EMCON Near Shore and Riverbed Profiling System is designed to record the profile of the coastal sea/river bed, where an echo sounder cannot be used. The system uses a hydrostatic pressure-based measurement sensor to measure the depth of the water column. Specialized electronics removes fast fluctuations caused by waves, boat movement and other water disturbances. The device continuously records the depth along with time. When the sensor is dragged over the bed, the system records the data continuously with time. The recorded data can be downloaded directly to a computer in Microsoft Excel or CSV format. The system can be used for surveying near coastal lines, wave breaker areas, rivers, lakes and other water bodies.

● Suitable for coastal, river, lake and other water-body surveys

Measurement Principle

The Near Shore and Riverbed Profiling System uses a hydrostatic pressure-based measurement principle. Hydrostatic pressure sensor measures the depth of the water column. Specialized electronics are used to remove fast fluctuations caused by waves, boat movement and other water movements.

Operations

The profiler is carried from a boat or dingy to the point where the mapping of the ocean floor is to begin. It is then lowered/dropped towards the ocean floor. The rope connected to the profiles is then dragged towards the beach at a constant speed. The profiler records the depth continuously while the profiler is pulled towards the shore.

Data Recording

The profiler continuously records measurement data every 2 seconds during the profiling operation. The recorded data is presented as depth versus time, which provides the profile of the ocean floor or river bed. The data from the profiler can be easily down loaded to a computer through a marine connector and the data is made available in Microsoft Excel/CSV file format.

River Bed Survey Operation

The profiler can be connected to ropes at both sides of the river. Surveyors can hold the ropes at either bank of the river. The profiler can be pulled from one bank to the other according to the convenience of the user. The rope arrangement also allows the profiler to be pulled back in the opposite direction if it becomes stuck on underwater materials.

Applications

● Near coastal line surveying
