Ponce de Leon channel shoaling and erosion studies Punta Gorda, Florida
The shoaling and bank erosion at Ponce de Leon channel, Punta Gorda, Florida, havecaused concern of harming the mangrove community along the channel. Three factorswere identified that could contribute to the bank erosion of Ponce channel. Theyare tidal induced current, wind waves penetrating from the Charlotte Harbor, andwakes caused by boat traffic. According to the field experiments and numericalmodeling studies, it was determined that the combined wind wave and tidal currentforce is the major cause to the bank erosion. Wind wave appears to play a moreimportant role because of its dynamic nature. For the present cross-sectionalchannel condition the tidal current alone is only a moderate erosional force.It was also found that reopening the barge canal would cut the tidal currentstrength in the Ponce channel by a half. This current reduction would reduce butnot eliminate bank erosion in the lower reach as the wind-wave induced force willremain to be an important erosional factor.A number of remedial alternatives were given in the report. The most direct methodis to provide bank protection. The extent of the protection depends upon theextent of wind wave penetration which could be as deep as 150 m into the channelunder the present channel entrance condition.
