A hydrographic survey was conducted for the purpose of locating channel depths. The survey party consists of the shore party and the boat party. On the shore, a staff gage was established in a securely place to such a depth that it will give a definite reading. The staff reading at the instant that the sounding was taken was 4.75m. The depth of sounding as recorded was found to be 10.75m. The elevation of the zero mark of the staff was 180.62m. Determine the elevation of the bottom of the channel.

Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.
