Whenever the river erodes, it erodes the rocks from the higher grounds. The river has immense energy to erode a bigger boulder. It erodes the bigger one and make it small, like pebble stones.
Further the river erode the pebbles to form sand and clay.
Most of the rocks and pebbles travels along with the water course where sand and clay travels along with the water columns in a creamy form.
When the river loss its energy during the dry season the sand and clay gets sediment to the bottom on the river.
