Physical Monitoring

Physical monitoring involves recording all of the physical parameters of the stream.  This means recording the characteristics of the stream itself and the area surrounding it. Common physical attributes to measure are: surrounding cover, type of stream bottom, stream width, depth, velocity, and discharge.  the cover surrounding a stream can greatly influence its characteristics.  It is important to note if any of the stream is covered by trees or particularly in the sunlight.  This can affect the temperature of the water and the organisms found in it.  The type of stream bottom can also determine what kinds of macro invertebrates that are likely to be present.
