2. A quadratic catchment area has its four corners in the following (x, y) coordinates; (0,0), (1000, 0), (0, 1000), and (1000, 1000) with both x and y in meters. Two rain gauges are located in the area. Gauge A has the coordinates (500, 500), and gauge B has the coordinates (1100, 500). During a rainfall, 100 mm were recorded in gauge A and 0 mm in gauge B. (a) Calculate the areal rainfall over the catchment using the arithmetic average method. (b) What would be the areal rainfall if the Thiessen method is used? (c) During a previous rainfall, a runoff coefficient of 0.8 was recorded. What is the runoff expected for the rainfall in (a)? (d) What is the expected rainfall in (b)? (e) Observed mass transport of phosphorous from the catchment was 100 kg. What was the concentration of phosphorous in the water?
