Abstract: A trenchless method of installing a new poured-in-place manhole liner provides structural rehabilitation to an existing buried manhole, and is extended above the existing manhole to a higher pre-determined elevation to match the finished grade of a raised levee design. The new liner can be formed in a single or double stage process, which substantially eliminates trenching and excavation of soil, so that new levee soil is not disturbed. The process is faster and less expensive than building a totally new manhole, and maintains the structural integrity of the levee.

Abstract: An artificial downwelling system, for example, can include one or more free-floating, self-propelled, or anchored wave-inertia pumps. In one embodiment, the wave-inertia pumps may be deployed on the oceanic side of an upwelling front. For example, the wave-inertia pump may pump warm surface water to deeper cold layers (e.g., below a sheared pycnocline of upwelling water) to disrupt the coastal upwelling. In some embodiments, a productivity of the artificial downwelling system can be controlled through remote telemetry, telecommand, and/or electromechanical tools. The artificial downwelling system may, for example, be powered by wave energy, and can be controlled using a telemechanical system powered by wind energy, and/or solar panel energy backed by electrical batteries.
