WebThe output flow direction raster. Each cell value represents the direction of the seepage velocity vector (average linear velocity) at the center of the cell, calculated as the average value of the seepage velocity through the four faces of the cell. It is used with the output magnitude raster to describe the flow vector. Raster Dataset In mathematics, a flow formalizes the idea of the motion of particles in a fluid. Flows are ubiquitous in science, including engineering and physics. The notion of flow is basic to the study of ordinary differential equations. Informally, a flow may be viewed as a continuous motion of points over time. More formally, a flow is a group action of the real numbers on a set. small claims court in pennsylvania limits

The length of the flow velocity vector is the flow speed and is a scalar. It is also called velocity field; when evaluated along a line, it is called a velocity profile (as in, e.g., law of the wall). small claims court in oregon
