Water depth-flow velocity coupled artificial fish spawning site design method
The invention relates to a water depth-flow velocity coupled artificial fish spawning site design method, and belongs to the field of ecological restoration engineering. According to the technical scheme, the water depth-flow velocity coupled artificial fish spawning site design method is characterized by comprising the steps that a spawning site of fishes under natural conditions is investigated, the water depth and the flow velocity of the natural spawning site is measured, and the optimal Froude number of the natural spawning site is calculated based on the water depth and the flow velocity; a slow flow is formed on an artificial fish spawning site and the upstream of the artificial fish spawning site by transforming the terrain of a riverbed, and the Froude number of the slow flow is smaller than 1; and the flow state of water flow is adjusted by arranging a flow adjusting engineering facility, so that the Froude number of the artificial fish spawning site is adjusted by taking the optimal Froude number of the natural spawning site as a target value.
