STUDIES

 

MEASURING EROSION PER WAKE

These Studies Measure the Erosion Each Time a Boat Goes by:

     Table of erosion per boat trip

     California, USA

          Data

     Maryland, USA

          Graph, erosion at different speeds

          Data & graphs of boat erosion & water level 1903-2005

Boat wake wave energy study Australia, 2008

Impact of Waves Created by Wake Boats- Canada, 2014

 

MEASURING EROSION PER YEAR

These  Studies Measure the Erosion per Year. They Did Not Count Boats, so They Do Not Show Erosion per Trip:

     English Broads

          Graph showing erosion at low speeds

          Data on erosion 1883-1976

     Virginia, USA

          Data on erosion 1849-1942

          Data & graphs of water level 1903-2005

     Atlantic Intracoastal Waterway, USA

     Quebec, Canada

 

LIFTING SEDIMENT OFF THE BOTTOM HARMS WATER LIFE
