An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr.
An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr.
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In-stream concrete structures were studied through model tests and river tests. The model studies indicated that four designs provided good habitat in the model stream. These structures were the inverted weir, the "V" structure, the slab with legs and the cylinder. Through the river studies it was determined that these structures did not influence enough of the total river area to be effective in providing good fish habitat. Also an appreciable amount of yearly maintenance would be required to free the structures from silting in, debris, and vandalism. The slab with legs was the only promising structure.

PRIME requirements for exposed concrete surfaces in dairies are that they should be easily cleansed and should not deteriorate in contact with milk and milk products.
In milking stalls, animal races and on loading platforms hardwearing surfaces which offer good foothold are also necessary.
