METHODOLOGY1. The rectangular weir is fastened to the designated part on the hydraulic bench.2. After that, the valve is opened and the rate of flow is measured.3. The depth above the weir crest is measured.4. The measurement should be made at a distance of about 2.5h upstream of the weir.5. The step of the experiment is repeated using four other discharge values.6. The rectangular weir is replaced with the triangular weir and the experiment is repeat using the step above.Flow Chart

APPENDICESPictureDescription

Talal is taking a reading at the scale after the needle is touching the surface of water.

Huda is recording a time for a water collected using stop watch after we prevent water flow out from hydraulic bench

They are waiting for the water accumulated in hydraulic bench which we need to record time for volume of water collected.

The needle is touching the surface of water using a rectangular weir.

Terrance is adjusting the position of the needle after we calculated the distance it should move.
