Abstract: Aspects of the present disclosure involve hydraulic systems and methods for altering a flow of a body of water, such as a river, channel, and/or other flowing or uncontained bodies of water. In one aspect, a hydraulic system provides a velocity barrier for the impedance of aquatic organism migration. More particularly, the velocity barrier may be adapted based on the swimming capabilities of one or more aquatic organisms to impede migration. The aquatic organism may be one or more species of fish, such as species sea lamprey (Petromyzon marinus). The example implementations shown and described herein reference the restriction of the sea lamprey. However, it will be appreciated that other aquatic organisms could be restricted by the presently disclosed technology, for example, with different hydraulic targets depending on swimming capabilities.

Abstract: A method for installing a liner in a large diameter pipeline. In accordance with the method, the interior surface of the pipeline to be repaired is prepared by removing excess debris and dirt. A repair composite is brought into the tunnel or pipeline in a dry state. Once the dry repair composite is laid out in the structure to be repaired the repair composite is folded out and saturated and wetted out with high pressure spray guns. The spray guns are employed within the structure and an appropriate resin material is applied as required to wet out the fiber material. A calibration bladder is inflated and holds the repair composite in place against the pipeline walls until the epoxy resin is fully cured. Once the process is complete, the bladder tube is retrieved out of the system leaving the repair composite as a stand-alone system.

Abstract: A caisson is modified to include side tabs thin can be gripped by side-mounted clamps on a vibratory hammer so that the caisson may be lifted into position from a horizontal position, oriented vertically, and driven into the ground without readjustment of the clamping of the vibratory hammer. An end cap installed permanently at the top of the caisson may provide an additional flange for receiving a lower clamp of the vibratory hammer to complete installation of the caisson, driving the caisson further into the earth until the tabs are buried in the ground. The flange may be sized to fit within a tower portion attached to the caisson eliminating the need for a replaceable flange system.
