Erosion can be slowed in a number of ways, but by far the cheapest is to plant vegetation. After that, it would depend on the type of erosion you are trying to slow down...
Marine erosionTo slow down Marine (Sea/Ocean) erosion, you could build an artificial reef, dump sand and/or various debris on the shore (which would be potentially unsightly) or you could build a sea defence system; including a sea wall as a secondary defence, and with wave breaks as a primary defence.
Fluvial erosionAlthough there are small scale erosions like rill and gulley, these are very difficult to source and eliminate. A river, however, can be far more devastating, and also far more easy to track. A river meander (bend) is a fickle landform, and moves with exceptional speed (in geological terms). One can move from one side of the valley to another in decades, and can disappear completely in the same time. To prevent the movement of these meanders, farmers reinforce the outside bank of the meander with concrete or with metal rods.
Aeolian erosionThere's really not a lot you can do here: apart from planting vegetation, there is little protection from the wind.
Glacial erosionGlaciers are unstoppable. Unless you used some kind of a huge flame-thrower etc. you could never hope to stop a glacier. On the other hand, glaciers aren't worth worrying about as the only rocks they erode are those they are in contact with, and that's not rock that you'd be worrying about - unless you reside somehow on the sides of the trough...
When wind slows down or meets an obstacle, it loses the energy needed to transport sediment and may deposit the material it was carrying. This process can lead to erosion around the obstacle where the wind's ability to move the sediment is diminished.
A waterfall is primarily created by erosion, as water flowing over a hard rock layer gradually wears it down and forms a drop. Deposition can occur at the base of the waterfall where the water slows down and deposits sediment, but the main process responsible for creating the waterfall is erosion.
Vegetation slows down erosion by creating roots that hold soil in place, reducing the impact of flowing water and wind. The roots also help to absorb water, reducing surface runoff. However, in some cases, vegetation can speed up erosion by adding weight to soil on steep slopes or by blocking natural drainage pathways, causing water to flow more forcefully over the surface.
Tributaries can both erode and deposit sediment. In the upper reaches of a tributary, erosion may occur as the flowing water picks up and moves sediment. Closer to the main river, deposition may happen as the velocity of the water slows down and sediment is dropped.
Vegetation such as plants, trees and grass can help slow down erosion by stabilizing soil with their roots and reducing the impact of raindrops on the ground. Additionally, structures like retaining walls, terraces, and riprap can also help to prevent erosion by redirecting water flow and reducing the rate at which soil is washed away.

Floods play a role in weathering, erosion, and deposition by carrying and transporting large amounts of sediment and rocks. During a flood, erosion occurs as flowing water removes and transports material. Deposition happens when the water slows down, causing sediment to settle. Overall, floods can accelerate the processes of weathering, erosion, and deposition by moving and redistributing Earth's materials.
No, tornadoes do not cause deposition. Tornadoes are mainly associated with erosion, as they can pick up and carry loose particles and debris within their strong winds. Deposition usually occurs when the wind slows down and drops these materials.
Along with friction, turbulence slows down the waters flow and also may erode the stream bed
