Discharge Practice Sheet

1.    You have measured the width of a stream as being 25 feet.  Its depth ranged from 5 to 7 feet with an average of 6 feet.  A chip of wood is seen to float downstream some 300 feet in 10 seconds.  What is the discharge of this stream

2.    You follow the stream downstream and come to a place where the stream is only 12.5 feet across.  You note that the discharge is probably the same as you calculated upstream.  The velocity is also the same as you determined upstream.  What is the probable depth of the stream at this new location?
