Work this one out. How to write a field report. -river discharge calculate 158 width, 9ft depth, and velocity 0.02 m/s. -water volume 22mm and infiltration rate 1 minute 16 Seconds.

Let's break this down. 1. How to write a field report A field report is a document that records observations and analysis from a specific site or event. It typically includes an introduction (stating the purpose, location, and date), methodology (describing data collection methods), observations/results (presenting detailed findings), a discussion (interpreting the data and noting limitations), and a conclusion (summarizing key insights). 2. Calculate river discharge To calculate river discharge, we need the cross-sectional area and the velocity. Step 1: Convert width and depth from feet to meters. Given: Width = 158 ft Depth = 9 ft Velocity = 0.02 m/s Conversion factor: 1 ft = 0.3048 m Width in meters = 158 ft × 0.3048 m/ft = 48.1584 m Depth in meters = 9 ft × 0.3048 m/ft = 2.7432 m Step 2: Calculate the cross-sectional area (A). A = width × depth A = 48.1584 m × 2.7432 m = 132.1209 m^2 Step 3: Calculate the river discharge (Q). The formula for discharge is Q = A × V. Q = 132.1209 m^2 × 0.02 m/s = 2.642418 m^3/s Rounding to two significant figures based on the velocity (0.02 m/s): Q ≈ 2.6 m^3/s 3. Calculate infiltration rate Assuming "water volume 22mm" is the depth of water that infiltrated and "1 minute 16 seconds" is the time taken. Step 1: Convert the time to seconds. 1 minute 16 seconds = (1 × 60 s) + 16 s = 60 s + 16 s = 76 s Step 2: Calculate the infiltration rate (I_R). I_R = Infiltrated depthTime I_R = 22 mm76 s ≈ 0.28947 mm/s Rounding to two significant figures: I_R ≈ 0.29 mm/s That's 2 down. 3 left today — send the next one.
