The manual is intended for use as a training guide and reference text, primarily for hydraulic engineers and technicians in the U.S. Geological Survey, but the manual is also appropriate for use by other stream-gaging practitioners . Streamflow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle.It is one component of the runoff of water from the land to waterbodies, the other component being surface runoff.Water flowing in channels comes from surface runoff from adjacent hillslopes, from groundwater flow out of the ground, and from water discharged . 4JcS'mOz9 v_,?k~pH,$a(NXu7bE[1v@'-&medG%,{#tsHI1h#v(Tyi_0v Aa>Z1d79S~RQnc)PVTD +W70m1.fS~hS`wOnf~J"qRj3[]hkl!
