Abstract
In this paper, the hydraulic characteristics of a sharp crested triangular side weir have been experimentally studied. It was found that the DeMarchi coefficient of discharge for a sharp crested triangular side weir in subcritical flow is related to the main channel Froude number, the apex angle of weir and ratio of weir height to upstream depth of flow. Suitable equations for discharge coefficient are also obtained.
