专利汇可以提供Means and apparatus for controlling fluid currents and selectively preserving and modifying topography subjected thereto专利检索，专利查询，专利分析的服务。并且Modular units are provided for utilizing the kinetic energy in waves, tides and winds to effect deposits of fluid entrained alluvium. The modules have front and rear surfaces so structured that arrays of the modules can effect shaped alluvial deposits or selective entrainment of alluvium to maintain or modify the topography at the situs of the arrays.，下面是Means and apparatus for controlling fluid currents and selectively preserving and modifying topography subjected thereto专利的具体信息内容。
1. Reaction means for fluid currents to selectively modify the action of such currents on the topography of a given situs and accrete alluvium entrained therein comprising: securing means mounting said reaction means at said situs in the path of said currents; an elongated curvilinear surface concave on a first face thereof defining an open face for said reaction means for receiving first currents and convex on the opposite face thereof for impingement by second currents opposed to said first and deflection of laterally directed currents; and at least two partitions substantially normal to said concave first surface and extending outward therefrom toward said open face; said concave surface reacting with impinging currents to create opposing currents attenuating the energy of said incoming currents and causing accretion of alluvium suspended therein adjacent said open face; and said partitions providing structural rigidity to said curvilinear surface and acting to impede the flow of current laterally of said concave surface; wherein said securing means includes a base on said reaction means and hold-down means selectively interconnected with said base to selectively orient said curvilinear surface and said faces thereof with reference to a given direction of fluid current; wherein said base includes first, second and third mounting ports defined in said base and disposed in a triangular array, one of said ports being centrally located on said base adjacent said open face and said base being substantially coterminate with the length and breadth of said reaction means; and wherein said hold down means includes pivot means securing said base at said situs through said one of said ports and an array of ground anchor means positioned about said pivot means selectively engageable with remaining respective ones of said ports.
2. A protection array for preserving navigational channels and the like against the alluvial action of incoming and outgoing tidal currents, said channel having first and second lateral boundaries extending from a backwater to a main body of water, comprising: a first row of spaced apart, mutually parallel modules anchored adjacent the first boundary of a said channel; and a second row of spaced apart modules anchored adjacent the second boundary of said channel in a substantially mirror image relationship with said first row of modules; each of said modules comprising a reactive surface which when impinged by tidal currents directs said currents back on themselves and attenuates lateral flow thereof over the length of said module to attenuate the kinetic energy therein and thereby constrain accretion of entrained alluvium from said currents adjacent said module and a fluid diverting surface contiguous over the rear face of said reaction surface; the said modules in each said row having their reaction and fluid diverting surfaces alternately disposed; and said surfaces being oriented with said channel to constrain a convergent flow in said channel for outgoing tidal currents and divergent flow from said channel for incoming tidal currents.
3. The invention defined in claim 2, wherein said modules at the extreme ends of each said row adjacent said main body of water have said reaction surfaces facing outboard of said channel.
4. The invention defined in claim 2 wherein said modules at the extreme ends of each said row adjacent said backwater have said reaction surfaces facing inboard of said channel.
5. The invention defined in claim 2, wherein said modules at the extreme ends of each said row adjacent said main body of water have said reaction surfaces facing outboard of said channel; and wherein said modules at the extreme ends of each said row adjacent said backwater have said reaction surfaces facing inboard of said channel.
