There is great potential for the expansion of the small or micro scale hydropower network.

Three types of weir were studied: Broad Crest … weirs were studied in detail; this is complimented by further studies in Flat V and Crump weirs. Flow data was collected for …

Because low-grade weirs are designed to impede flow of water there is concern from producers that they will lead to … decreased drainage and increased flooding in adjacent fields. The purpose of this study was to determine if weirs increased the … risk of flooding and backflow. Analyses were conducted to evaluate the effect of low-grade weirs on hydrology. The first …
