Authorizes the Secretary to carry out projects for the protection, restoration, and creation of aquatic and ecologically-related habitats, including wetlands, in connection with dredging for construction, operation, or maintenance of an authorized navigation project. Specifies that such projects shall be undertaken, subject to appropriations and Federal cost-sharing limitations, in any case where the Secretary finds that: (1) the environmental, economic, and social benefits of the project justify the cost; and (2) such project will not result in any further environmental degradation. Specifies that any such project shall be initiated only after non-Federal interests have entered into a cooperative agreement, according to specified provisions of the Flood Control Act of 1970, under which such interests agree to: (1) provide 25 percent of the cost associated with the project, including provision of all lands, easements, rights-of-way, and necessary relocations; and (2) pay 100 percent of the cost of operation, maintenance, replacement, and rehabilitation costs associated with the project.

Authorizes the Secretary, in accomplishing the maintenance, rehabilitation, and modernization of hydroelectric power generating facilities at water resources projects under the jurisdiction of the Department of the Army, to increase the efficiency of energy production or the capacity of these facilities if, after consulting with other appropriate Federal agencies, the Secretary determines that such uprating: (1) is economically justified and financially feasible; (2) will not result in significant adverse environmental impacts or effects on the purposes for which the project is authorized; and (3) will not involve major structural or operational changes in the project. Authorizes the Secretary, at a water resources project where the non-Federal interest is responsible for performing the operation, maintenance, replacement, and rehabilitation of the project and the Government is responsible for paying a portion of such costs, to: (1) provide a payment of the estimated total Federal share of such costs (based on a specified formula) to the non-Federal interest after completion of project construction; and (2) make a payment only if the non-Federal interest has entered into a binding agreement with the Secretary to perform the operation, maintenance, replacement, and rehabilitation of the project, subject to specified requirements.

Amends the Water Resources Development Act of 1986 to require that credits for project lands, easements, relocations, and rights-of-way include full value of foregone royalties on subsurface minerals, such as sand, where State royalty schedules have been established on the commercial mining of such resources. Limits design and construction costs assigned to projects under such Act for purposes of cost-sharing by non-Federal interests to the direct costs of such projects (and excludes any departmental overhead or general and administrative overhead costs). Makes this provision applicable to projects authorized in this or subsequent Acts and to cost-sharing agreements for projects not specifically authorized by the Congress entered into after the date of enactment of this Act. Directs the Secretary and the Assistant Administrator for Research and Development at the Environmental Protection Agency (EPA) to coordinate an annual review of the environmental research activities conducted at their respective research facilities. Extends the time of transfer of lands and management responsibilities with respect to specified portions of the Cross Florida Barge Canal project. Authorizes and directs the Secretary to investigate and carry out saltmarsh restoration projects along the coastline of the State of Connecticut, subject to specified cost-sharing requirements.

Specifies that the Secretary shall consider the protection of coastal resources through placement of beach quality sand on beaches as being in the public interest whenever such sand would otherwise be disposed of offshore. Requires the Secretary to establish by regulation a process for development of long-range plans for financing and execution of projects for beach nourishment and inlet management within each affected State. Sets forth minimum requirements with respect to such process and the amendment or termination of such plans. Authorizes appropriations.
