Application and effect of SCL film and SK polyurea in aqueduct roughness reduction transformation project

In order to explore the recommended roughness value and application prospect of SCL impermeable film and SK spray polyurea in reducing roughness and increasing flow in water conservancy projects, the prototype observation test is carried out in the typical aqueduct of the pumping irrigation area in...
