Choosing a method of transportation for transporting objects can be a confusing decision. Some of the options include airplanes, oceans, rivers, and even the earth itself. Here are a few things to consider before choosing a method.
Transport by rivers
Among the most important factors affecting the movement of sediment in a river are the size and the shape of the particles that are suspended in the current. Generally, the larger particles remain suspended while the smaller particles settle out as the current slows down. Moreover, the flow can also push sediment along the bottom of the waterway. The sediment can be made up of organic material such as decomposing plants, chemicals, and sedimentary minerals. In addition, the geography of the region can also influence the load. For example, in a river with headwaters located in swampland, the sediment will usually include decomposing organic matter.
The sediment load can be broken down into two categories: the suspended load and the bed load. The suspended load is usually dominant in river flows, while the bed load is more prevalent in tidal flows. The suspended load is also known as the jumping load, whereas the bed load is the rolling load. Both of these types of loads can be predicted using some of the following formulas.
The formulas are based on the assumption that the sediment transport rate is a function of the size-shape-density distribution of suspended particles. These formulas are usually based on a standard deviation of the particle diameter. However, if the particle size changes, the current velocity also changes. This can affect the sorting of the minerals.
