Problem 2: Stream cross-sectional areas (A) are required for a number of tasks in water resources engineering, including flood forecasting and reservoir designing. Unless electronic sounding devices are available to obtain continuous profiles of the channel bottom, the engineer must rely on discrete depth measurements to compute for the Area. An example of a typical stream cross section is shown in the figure below. The data points represent locations where a boat was anchored and depth readings were taken. Use Simpson's 1/3 rule (let n = 10) to estimate the cross sectional area from this data. - Water surface 1.8 4 6 4 3.6 3.4 2.8 20 Distance from left bank, m Depth,

A dumpy level is set up at one end of a line 120 m long for the purpose of determining the instrument’s stadia interval factor. The line is marked by hubs at every 30 m and a stadia rod is held at each hub. The stadia intercepts at each location of the rod were observed as follows: 0.308, 0.613, 0.918 and 1.222 meters, respectively. The average value of the instrument’s stadia interval factor is:
