Self-Cleansing Urban Drain Using Sediment Flushing Gate Based On Incipient Motion

Sediment deposition in urban open concrete storm drain has caused many adverse effects to the drainage system such as flash flood and environmental pollution. This study aimed to provide recommendations for the purpose of sedimentation mitigation in urban open concrete storm drain. To understand the...

This study aimed to provide recommendations for the purpose of sedimentation mitigation in urban open concrete storm drain. To understand the physical characteristics of sediment deposition; sampling was taken from 57 locations in Kuching city, surrounding towns outside Kuching city and Penang consisting of residential, commercial and industrial areas and subjected to sieve analysis.

Combining the results from the current incipient motion experiments with the results from an earlier researcher for a 0.3 m wide flume, multiple linear regression were performed and the best equations for each of the critical shear stress and critical velocity approach were developed. A design chart relating the self-cleansing design relationship between drain minimum slope with the design minimum flow rate and the respective standard drain size was also developed.
