Abstract: A lock and dam system for a waterway includes a dam extending across the waterway, a channel having a first entry-exit opening on a first side of the dam and a second entry-exit opening on a second side of the dam. The channel includes a lock. The system further includes a fascia proximate first entry-exit opening in the channel, and a fender system to protect the fascia from impact. The fender system includes a plurality of resilient flexible support element, a first panel supported by a first one of the plurality of support elements in front of the fascia and a second panel supported by a second one of the plurality of support elements in front of the fascia. The first and second panels overlap in a first direction parallel to the fascia and a second direction perpendicular to the fascia. In one exemplary embodiment, the first panel has a first shoulder and the second panel has a first step facing and overlapping the first shoulder.

Abstract: A vehicle impact system includes a road accommodating vehicle traffic in a direction along its center line, a support structure and first and second adjacent energy-absorbing fender elements supported by the support structure and extending adjacent to the road. Each of the first and second adjacent energy-absorbing fender elements includes an elastomeric leg extending non-parallel from the support structure and a contact panel extending from the leg. The contact panel has a contact surface extending substantially parallel to the road center line, a forward end and a rearward end. The forward end of the first adjacent fender element faces the rearward end of the second adjacent fender element such that when the contact surface of the first adjacent fender element is engaged by a vehicle, the leg of the first adjacent fender element resiliently flexes to move the forward end of the first adjacent fender element into engagement with the rearward end of the second adjacent fender element.

Abstract: The lock and dam system for waterway includes a dam extending across the waterway, the channel having a first entry-exit opening on a first side of the dam and a second entry-exit opening on the second side of the dam. The channel includes a lock. The system further includes a fascia approximate first entry-exit opening in the channel, and a fender system to protect the fascia from impact with objects generally moving in a first direction. The system includes a first panel, a second panel, a first support element coupled to one of the first and second panels and coupled to the at least one fascia and a second support element coupled to one of the first and second panels and coupled to the at least one fascia. The first support element extends oblique to said one of the first and second support panels with the second support element extends oblique to said one of the first and second panel.
