Hydrographic Surveys

APS was recently selected to complete a hydrographic survey of the Satsop River. The cross sections were every 150 feet along a three-mile meandering waterway. The survey incorporated fast static and RTK GPS along with conventional survey and intermittent fathometer and leadline reading. The final product included plan view and 83 cross sections of the river. Some of the cross sections were as wide as 1,000 feet.
