TM 55-1945-205-10-4 0015 00 7 0015 00 4. As an example, assume the following conditions: a. Sea State: 3 b. Tide Range:   3.5 c. Bottom Slope: 1:100 5. Using Sea State 3 graph, locate intersection of bottom slope and tide range. If intersection of bottom slope and tide range falls between two curves, select curve for greater number of causeway sections. A fifteen section causeway is required for given conditions in the example.
