In-stream aquatic trash capture technologies

Relatively low-cost technologies that can be used to capture trash in streams or rivers before ultimate removal from the environment. Technologies must be suitable for use by smaller municipalities or non-governmental organizations that may not have much experience with using such devices, and must therefore be easy to install, clean out and maintain. Relevant direction on conditions under which the technology would ideally be used (e.g., stream flow rate) or other needs for use (e.g., need for power source, space requirements, etc.) should be clearly specified.
