For a tractor tire, the ideal slip ratio for optimum field operation is:

During a heavy storm event, rainfall data from five stations (A, B, C, D, and E) in a catchment is recorded. Stations A and D failed to record rainfall. Normal annual rainfall and available storm rainfall are: A(1600, ?), B(1500, 105), C(1400, 95), D(1550, ?), E(1450, 90). Use the Normal Ratio Method to estimate the storm rainfall at Stations A and D.

Which of the following is a disadvantage of Thiessen polygon method?

A storm of 12-hour duration delivers 90 mm of rainfall over a 150 km² catchment. The average infiltration rate is 3 mm/hr, and losses due to evaporation and depression storage total 10 mm. Calculate the total surface runoff volume in million cubic meters (MCM).

Describe the traction characteristics of wheeled tractors versus crawler tractors in different soil conditions. Justify when crawler-type would be advantageous.

What is a typical map scale used for planning reservoir submergence and command area?

A 4-hour storm delivers hourly rainfall depths of [10, 20, 25, 15] mm. If the ö-index (constant infiltration rate) is 6 mm/hr, compute the total effective rainfall depth (in mm).

Which of the following rainfall types is most intense?

The total volume of direct runoff from a watershed is equal to:

Two tangents intersect at chainage 1050 m with a deflection angle of 40°. A circular curve of radius 300 m is to be provided. Find the chainage of start and end of curve.

A dumpy level is tested for collimation error. Two pegs A and B are placed 60 m apart. Staff readings when instrument is 10 m from Peg A: A = 1.210 m, B = 1.325 m. Staff readings when instrument is at midpoint: A = 1.215 m, B = 1.330 m. Calculate the collimation error and determine if the instrument needs adjustment.
