A New Concept of Frontal Migration System for Fish ‒ for Overflow Weirs and River Sills

In this paper we present a new frontal migration system for fish which could be used for overflow weirs and river sills. Since movement of fish is the most crucial thing in the healthy river environment fish passes are necessary to predict in any place where hydraulic structures are designed or any river engineering works are applied in the river channel. Thus in our paper we are giving a proposal of a new fish migration system when any river cross section weirs, sills or other low head hydraulic structures are planned. We hope our system would be built one day proving the advantage of using it.
