Abstract:
Rivers, the natural drainage, are the most important water resource in the world but it is difficult to measure accurate value of discharge of river during floods, due to change in bed formation of river. Accurate measurement of river during flood is very important because underestimation of flow may cause more disaster and overestimation may lead to wastage of resources. Embankment weirs, in this regard, e.g. railway embankment or highway embankment may be used for the measurement of discharge during flood. In this research paper, Embankment weirs with symmetrical side slope in open channel flow were investigated. Three different discharges were used in this study and graphs were plotted against each discharge to observe the effects of discharge on head loss. Moreover, embankment weirs with different side slopes were also investigated. This research will help to understand the effects of discharge on head loss in Laboratory and also in the field. Recommendations for future work have also been provided at the end.
