Waves or wake produced by boats is the primary factor by which boats can influence shoreline erosion.
Boat wave erosion. Small lakes are likely to be most influenced by boat-induced waves as boats may operate relatively close to shore and wind-induced waves are reduced. AHO survey teams have noted that even small boats could set off a series of waves to the shore that would exacerbate erosional processes when coinciding with very high tides. Wave action from passing boats is causing problems in the shoreline of Kal Lake.
Waves as small as 4 inches can alter slopes in sandy or silty unvegetated areas and major erosive events occur with wave heights at about 1 foot. EROSION AND BOAT WAKE. In 20 afternoons 20 boats would remove 1400 square feet of bank per mile.
Boat wakes suspend and carry nearshore sand particles into deeper water offshore ultimately leading to shoreline steepening. Shoreline erosion releases soil and nutrients to Newman Lake which contributes to these conditions during the critical summer months. On a global scale the size speed and traffic of large vessels.
There are many natural causes wind-generated waves water levels ice slope of the bank absence of vegetation as well as human deforestation of shorelines wave action from passing boats. Shoreline erosion is a process that occurs along all watercourses. Reduced erosion equates to improved beach quality for recreation and habitat requires less costly protective measures and leads to an enhanced watershed for property owners and recreational users.
Erosion boat wake impacts include vegetative damage and disruption of faunal communities Parnell and Koefoed-Hansen 2001. Lauren Lypchuk says temporary boating restrictions on Kalamalka Lake would go a long way in saving the shoreline. Wind wave periods were up to 2 seconds while measured boat wave periods were up to 8 seconds Gourlay 2010.
In Waikato River boat traffic was estimated to. Vegetation as well as human deforestation. EROSION AND BOAT WAKE Shoreline erosion is a process that occurs along all watercourses.
