Abstract
A fish passage system having flexible textile materials forming a conduit to transport fish across river barriers encountered during migration. The system can include modular support structures that can be independently secured to riverbeds to form conduit supports, dams, hydropower structures, and the like.
Claims20
A modular upstream fish passage system comprising:
- an upstream portion having an exit to a conduit;
- and
- a downstream portion comprising the conduit, the conduit comprising high-strength textile materials to form a chute that hangs on structural supports.
A downstream fish passage system comprising:
- an upstream portion, the upstream portion comprising an entrance structure, and an adjustable height conduit entrance port;
- and
- a downstream portion linked to the upstream portion and attached to a downstream face of a dam with sacrificial connectors, the downstream portion comprising a flexible textile conduit arranged in a spiral configuration around a central mast.
A system comprising:
- a plurality of modules vertically assembled to form at least one stack;
- a post-tension anchor securing the at least one stack to a foundation on a streambed;
- and
- wherein the at least one stack is not structurally affixed to any other stack.
