A new technique for determining the surface level of salt marshes and other uncompacted sedimentary environments |
|
| Authors: | Alan P Carr |
| Abstract: | The method described involves the use of an electro-optical distance measurer mounted on a theodolite. Observations are taken onto a series of acrylic reflectors, aligned at right angles to the line of sight, and slope distances and vertical and horizontal angles are recorded. From these data it is possible to obtain surface heights to an accuracy of ±0·5 cm at 200 m and to avoid any direct disturbance of the site under investigation. |
