Water depth Assessment by Digital Echo Sounder
MetadataShow full item record
This paper presents a method for evaluating the depth of the water by Digital Echo Sounder device using a resonance wave to check sediment that is deposited in front of the pier. In every year, the depth may change owing to current bring some of sand, mud, etc increase and/or various object at bottom river / sea base Hence, The Hydrographic shall carry on at least yearly basis. The result of the examination will be processed, mapping the depth of the water surface, cutting and evaluating, calculating the amount of material, dredging in front of the pier. From the study, it was found that the depth of the water depth measurement method by the Digital Echo Sounder helps to check the depth of the water easily and accurately. Conducting hydrographic surveys and design (Line) survey lines will help to work faster and more efficiently. The result can be evaluated to calculate the amount of material before dredging in front of the dock. Water depth assessment examination should be checked annually.
