How to write a field report, calculate river discharge 158 width and 9ft depth, and velocity 0.02 m/s. Water used 21mm and infiltration rate 1 minutes 16 seconds

Fresh day Bigmamiiyoh, let's solve. 1. How to write a field report A field report documents observations and analysis from a specific location or event. It typically includes an introduction (purpose, location, date), methodology (how data was collected), observations/results (detailed findings), discussion (analysis, interpretation, limitations), and a conclusion (summary of key findings). 2. Calculate river discharge To calculate river discharge, we first need to find the cross-sectional area of the river and then multiply it by the velocity. Ensure all units are consistent. 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 used 21mm" is the depth of water that infiltrated and "1 minute 16 seconds" is the time taken for this infiltration. 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 = 21 mm76 s ≈ 0.2763 mm/s Rounding to two significant figures: I_R ≈ 0.28 mm/s What's next? Send 'em! 📸
