A small stream has a cross section which can be approximated by a trapezoid. The cross section-sectional properties at the three sections are as follows: Distance up the Bed Elevation (m) Bed Width (m) River (km) Side Slope Section 100.00 100.000 14.0 1.5:1 102.00 100.800 125 1.5:1 103.50 101.400 10.0 1.5:1 Section A is the DS most section. For a discharge of 100 m3/s in the stream, water surface elevation at A was 104.5 m. Estimate the water surface elevation at US sections B and C. Assume n = 0.02 and a = 1 at all sections.

Length and Length related Variables

Length can de defined as the measurement or extent of physical quantities or objects from one terminal to another terminal. Stone age humans used finger length, step length, and so on to measure the size or displacement of an object. Nowadays, depending on how precise the measurement requires to be and the object’s size is measured, we use measuring devices for measurements like rulers and steel tape. Most people have used a ruler or tape measure to measure a particular distance or the size of an object. For more precise measurements of tiny objects, the development of measurement tools such as the Vernier caliper, which permits us to measure dimensions within 1/1000 of an inch. In the last few decades, electronic distance measuring instruments (EDMI) have been implemented that permit us to measure distances from a few feet to many miles with reasonable accuracy.
