Research Papers in Open Channel Hydraulics (Part 3).

      Аннотация: This book contains eight research papers in open channel hydraulics.The characteristics of roughness materials and the properties of intermediate scale roughness and large scale roughness are emphasized. We observe that roughness materials are advantageous from the point of view of more mean depth of flow which will be used for irrigation and water distribution purpose. Also, the high velocity of flow is reduced to get the permissible value of velocity and the erosion is prevented. The relationship between different roughness parameters have been discussed.
