| Abstract: | This paper at first briefly introduces the up-to-date research results about topographies of scouring funnels and flow movement in front of an intake and concludes the primary characteristics of scouring funnels, then the method of the flow velocity measurement-and experimentary results have been described detailly. The specifications of the flow velocity distribution have been gotten, and the deformative and steady causes of scouring funnels havre been discussed in the last of this paper. |
