In the Rational Method, the runoff is directly proportional to the catchment area.

• True

• False

The primary advantage of using a pressure transducer in discharge measurement is its ability to:

• Measure water velocity

• Measure pressure differences accurately

• Be used in shallow water

What is the primary function of a discharge recorder?

• To measure rainfall

• To record the water level fluctuations

• To determine soil moisture content

The float method is generally used in large rivers and high-flow conditions.

• True

• False

Float gauges are ideal for measuring discharge in deep and high-flow rivers.

• True

• False

Pressure transducers are typically installed below the water surface and measure the height of water above them, converting this pressure into a corresponding stage reading.

• True

• False

The Rational Method is best suited for estimating runoff from mountainous catchments.

• True

• False

The velocity-area method can be used to calculate discharge in both high and low-flow conditions.

• True

• False

The velocity-area method requires accurate depth measurements at different points across the river, along with flow velocity at each corresponding depth.

• True

• False

The Rational Method can be applied to both small and large catchments with significant runoff.

• True

• False
