Entrainment is erosion by the movement of material in a flow; in other words, erosion by water. As the erosive process proceeds, channels are cut where the water flow concentrates. Sediment is depositied by the water flow as it slows down over slopes of lesser degree, and areas that are flat.
Some of the controls have a Trend button next to them. These trend buttons allow you to set variables over a series of frames. Each frame of any animation may be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Trend graphs have equidistantly spaced vertical lines. For animations under 100 frames in length, each of these lines represents a frame in the animation. The number of frames in any one sequence can be altered using the Sequence controls item from the Timeline pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames.

This is the amount of rain that falls.
This is the level at which the erosion ceases (water running into a large body of water only deposits sediment, rather than continues to cut a channel). This will directly relate to the Sea Level control in the Landscape operator.
This is the number of times is rains. As this is increased, the time the operation takes will also increase.
This is the amount of sediment that the water can carry. In nature, this varies with the type of soil.
