The position coordinates of 5 rain gauge stations A, B, C, D and E located within the basin with to a coordinate axes system whose %- axis and origin are coincident with diameter and center of the circle are (5,5),(-5,5),(-5,- 5),(5,-5) and (0,0) km respectively. If the rainfall recorded at these rain gauges are 85, 92, 77,80 and 105 mm respectively. i) Determine the average depth of rainfall using Thiessen method. ii) If station A failed to report the rainfall during a storm, and the storm rainfalls recorded at four surrounding gauges B, C, D, and E are 96, 70, 84 and 100 mm respectively, Determine the missing rainfall at station A.

From a transit line to the edge of a river a series of perpendicular offsets are taken. These offsets are spaced 4.0 m apart and were measured in the following order: 0.5 m, 1.4 m, 2.5 m, 5.6 m, 8.5 m, 7.4 m, 3.8 m, 5.1 m, and 2.3 m. Determine the area included between the transit line, the river’s edge and the line offsets using (1) Trapezoidal Rule, (2) Simpson’s One-Third Rule.
AREA OF RANGE CROSS-SECTION. Soundings were taken along a 38-m long range across a lake (see accompanying sketch). The horizonta! distances between soundings and the depth of the soundings are indicated in the sketch. Determine the area (in sq m) of the cros-section. Assume the area of the two end zones to be negligible. 3.
