Runoff is water flowing over land that carries particles of sediment.
Water and water flow are the main contributors to erosion of all rock types. Water flow assists in the transportation of these eroded rock particles to a point of deposition, where additional layers of sediment are added. Eventually, cementation of the rock particles may occur, forming a sedimentary rock.

Sediment accumulation is where sediment accumulates generally in the point of the lowest elevation. If sediment is in a river generally the sediment will accumulate at the mouth of the delta when entering the marine environment (proximal to distal).
Sediment layers are squeezed from above by the weight of overlying sediment, causing compaction. Compaction squeezes out air and water between the sediment particles. Minerals form as the air and water is squeezed out, cementing the particles together, and forming sedimentary rock.
Is called a deposition.
Abrasion
Whenever the force of friction of the particles, when they touch the floor, is greater than the force with which the water carries them. That depends on a lot of factors, including the speed of the flow, the size and material of the particles, their exact shape, how rough or smooth the floor is, and probably a few more details.

The greater the streams rate of flow, the greater the amount of erosion, the larger the sediments.
