Sand + Silt Layer Height or Thickness = 10 cm. Silt Content of Sand = (1 cm / 10 cm) x 100 %. Silt Content of Sand = 1%. So, from the above Test and calculations, we can say that this sand has a 1% silt content. The silt content limit in the sand as per IS code is 8%, so this sand we can use this for construction purposes.

Wave energy does the work of erosion at the shore. Waves approach the shore at some angle so the inshore part of the wave reaches shallow water sooner than the part that is further out. The shallow part of the wave ‘feels’ the bottom first. This slows down the inshore part of the wave and makes the wave “bend.”. This bending is called ...
