| The runoff from an urban catchment is increased because of the gravitation of the population towards cities. For this reason, water level increment in confluence area makes it impossible to drain internal water and thus produces flood out in upstream areas. In this study, flow variations of main channel are measured which is caused by combining storm sewer into main channel in small watershed. Depth increment in main stream is analyzed due to flowrate and slope in main channel and flowrate, slope is getting steeper, and also due to low flowrate in main stream and high flowrate in tributrary channel. For the degree of confluence, depth ratio decreases when the degree is getting small. As mentioned above, main factors influencing the depth ratio increment of confluence channel are in the order of the degree of confluence, and the flowrate of tributary channel and main channel. |
