Sediment transport

Sediment transport or Soil transport is the movement of solid particles, usually due to the combination of gravitational forces acting on the sediment, and the movement of the liquid at which the sediment enters. Soil erosion occurs in natural systems where the particles are sandstones (sand, rocks), mud, or clay; the liquid is air, water, or ice; and the gravitational force that works to move particles to the landing surface. Sediment transportation or soil migration due to the movement of liquids occurs in rivers, lakes, lakes, oceans, and other bodies of water as a result of currents and waves. Transportation is also caused by glaciers as they flow, and to places on earth under the influence of wind. Soil erosion due to gravity alone is possible in most sloping areas, including hills, scarves, cliffs, and the continental shelf — the continental boundary of the slope.

The following data were taken along a center line of a dam AB. The staff had been held in the 1st case at a starting point (A) and then at 20m intervals. The staff readings were: 0.765 / 1.064/ [0.616] / 1.835 / 1.524. The level was then moved forward to another position and further readings were taken as follows: 2.356 / 1.378 / [2.063] / 0.677/ 2.027. The last reading was at point (B). The R.L of (A) is 41.819m. 1- Enter the above data in a level book form. 2- Find the reduced level of points using height of collimation method. 3- Check the results. 4- Calculate the gradient from A to B.
