Situation 01. In a survey within the catchment area of a lake, Thiessen polygons were established by setting up a transit at Point Z, which is the inner portion of a four-sided lake MNOP. The readings are as follow: BEARING N 40°30' W N 38° E S 70° E | S 60° 15' W | 695.10km RAINFALL, ft DISTANCE 420.35km LINE ZM 0.211 ZN 530.15km 0.26 zo 480.75km 0.239 ZP If the rainfall from the area of bounded by ZMP is the Arithmetic Mean of the other rainfalls, compute the average precipitation (in cm) by Thiessen Polygon Method. Situation 02. Given the following data gathered on December 4-23, 2011, compute for the required inflow (in cu.ft/hr) in order to have an increase in storage of 14cm.
