The map following problem 2.17 shows the location of 8 rain gages and the boundary of a watershed. The rainfall depth for a certain storm are as follows; gage A, 5.6 inches; gage B, 4.2 inches; gage C, 3.9 inches; gage D, 2.5 inches; gage E, 1.8 inches; gage F, 0.9 inches; gage G, 2.4 inches; and gage H, 0.3 inches. Use the thiessen polygon method to determine the mean rainfall depth over the watershed for this storm event.

Problem 2.17

The following map shows the location of 8 rain gages and the boundary of a watershed. The rainfall depths for a certain storm are as follows: gage A, 25 mm; gage B, 18 mm; gage C, 92 mm; gage E, 192 mm; gage F, 175mm; gage G, 152 mm; and gage H, 168 mm. Use the thiessen polygon method to determine the mean rainfall depth over the watershed for this storm event.
