Question
UU area of the seabed than wider conventional shipborne surface of echo sounders, which operate on the the water. The shallower the water, the more pronounced is this advantage. In very shallow water, the shipborne multibeam echo sounder can cover only a very narrow swath of seabed and runs the continual risk of hull bottom damage. (Table 8-6). Problems 8.1 through 8.8 combine to form a comprehensive engineering project; the project can be covered completely by solving all the problems of this section, or individual prob- lems can be selected to illustrate specific topics. Numerical values can be chosen as meters or feet. All field and design data for these problems are shown on this page and on the following pages. 8.1 Establish the grid, plot the elevations (the decimal point is the plot point from Table 8-5), and interpolate the data to establish contours at 1-m (1-ft) intervals. Scale at 1:500 for metric units, or 1 in 10 ft or 15 ft for foot units. Use pencil.Explanation / Answer
