Abstract

Automated techniques for sediment core site positioning, hydrographic survey, and contour mapping are described. The computer contouring system can be extended to calculate values for morphometric variables such as maximum length (1max), maximum width (wmax), lake perimeter (10), lake area (A) and lake volume (V). The techniques are exemplified using results from Augher Lough, Northern Ireland.
