| description | Purpose
– Flood flushing is one natural cleansing capability of a natural river channel to wash away in‐stream pollutants and debris. The purpose of this paper is to explore the flood flushing restriction in a tributary due to its regulated main river channel between two barrages.
Design/methodology/approach
– In the absence of detailed data, a concerted effort of computer river modelling is conceptualized to represent possible flushing conditions.
Findings
– Regulation schemes of barrages are deduced to interrupt the natural tidal and river flow interaction zones and thus impede river flushing capability.
Practical implications
– Modelling of barrages’ operating modes suggested that though the man‐made structures are unable to replicate natural flood flushing, proper operations offer a secondary option to achieving the desired water quality objective in a constrained tributary.
Originality/value
– Studies on minor tributary of modified main‐stem river are few. The attended tributary‐trunk relationships carry the credibility of this paper. |
