영문 초록

  As the roughness coefficient by existing Manning table is used by technician"s experience and judgement, it isn"t always correct.
  This study as a try to make quantitative roughness coefficient is to suggest a new application mode computerizing roughness coefficient by surveying the velocity and hydraulic condition of small rivers.
  The bound of roughness coefficient was 0.027～0.180 and its values distribute uniformly. This means that the roughness coefficient adapt value by Manning table cannot fill up the transformed value when the small rivers are low.
  The roughness coefficient computation mode in this study with hydraulic radius(R), channel slope(I), average grain diameter(D) as subject factors presents as follows.
  n´ = 5.97 R<SUP>0.671</SUP> I<SUP>0.452</SUP> D<SUP>0.059</SUP>
