Abstract: A storm-water redistribution device and installation are described for providing headloss and redistribution of a flow of storm-water runoff. The device includes an elongate, tubular, geotextile enclosure having a plurality of transverse partitions therein that form a plurality of segments along the length of the device. Each segment is filled with a particulate material, such as gravel having a desired grade size or distribution thereof. Longitudinal partitions are provided to form one or more transversely positioned compartments. The device is installed perpendicular to a slope to intercept runoff flows. The flow infiltrates the device and is diverted into vertical infiltrating flow, longitudinal flow that distributes the flow along the device length, and transverse flow that exits the opposite side of the device as overland or subsurface flow of reduced velocity. The partitions enable retention of the particulate materials in desired positions within the device during manipulation and use.
