A construction method of reclaiming land from the sea based on the basement utilization, which implementation steps are as follows: a. installing a dike along the coastline, enclosing a central reclamation area by the dike and the coastline; b. installing crisscross enclosures in the central reclamation area, dividing the central reclamation area into a mesh area by the enclosure and the dike; c, pumping drainage of seawater in a block area in the mesh area, forming land in the block area; d. constructing the enclosure in the mesh reclamation area, using the enclosure and subsidiary roads to form road arteriality; the block area being lower than the height of the enclosure, constituting a grid-like high-road/low-land land supply mode; e. developing the block area into an underground space area.

A structure for restraining debris in a stream, including lateral walls, which delimit between them a flow section in a bed of the stream. This flow section includes an upper portion that includes set between the lateral walls, a structure for retaining material arriving from upstream, and a lower portion that identifies an opening for outflow.

A system for excavating sediment deposits from water storage reservoirs that equalizes the mass flow of sediment entering the reservoir with the sediment mass in the combined discharge from a dredge and the reservoir outlet system to the downstream water course. One or more remote instrument stations located on the inflow streams to the reservoir collect data that is used by the dredge control system to adjust the mass flow output from the dredge using data collected from the remote reservoir outlet instrumentation located downstream of the reservoir.

A sediment control system for a contaminated source, comprising an intake system for reversibly diverting flow from the contaminated source to a pipeline extending from the intake system to a plurality of spaced discharge outlets in a low turbulence zone within a water body to minimize mixing of the contaminated source flow with the water body. The source may be a stream, an industrial discharge, a construction site siltation settlement pond, a community storm drain, or a mine tailings source, The water body may be a lake, an ocean, a settlement pond, or a water reservoir.

A multi-layer device comprising a first substrate, a first electrically conductive layer on a surface thereof, and a first current modulating layer, the first electrically conductive layer having a sheet resistance to the flow of electrical current through the first electrically conductive layer that varies as a function of position.

The Integrated Drain Gate Seawall System (IDGSS) was designed to mitigate flooding due to rising sea water, severe rain and storm damages at costal area or other various waterfront properties like riverbanks, bay, beach, ocean, lake, marsh and low lying areas. The IDGSS has incorporated two functions simultaneously by separating water and land with a flood resilient fixed water barrier wall, but more importantly, has an automatic drainage system, especially for an unexpected severe and prolonged storms; to address the unintended consequence of trapping water inside the pre-existing water barrier walls. Unfortunately, during these severe storms, the trapped water has created a bathtub like scenario by the manmade fixed wall barriers, and causing an insult to an injury to an already devastated storm conditions, due to a lack of drainage systems. To mitigate this type of severe drainage problem, IDGSS was created with a characteristics of a concrete wall blocks, which includes a one-way valve or flap drain gate inside as a single unified structure, with an adjustable one-way valve or flap drain gate specification; with a various shape, sizes, materials and configurations for both one-way valve or flap gate and wall blocks; and adaptable retrofitting mechanisms to meet the site specific topography and special drainage needs. To protect the one-way valve or flap gate drainage system and to allow for an efficient drainage pathway system, the wall blocks are built to withstand severe wind and unpredictable weather conditions to become storm resilient, pressure reducing mechanism within the unlimited combinations of geometrical wall shape and size arrangements. Thus, the IDGSS is a reinforced wall system that can adapt to a specific drainage problem by allowing the trapped water to be returned back to where it came from as long as the water recedes by gravity.

A multi-layer device comprising a first substrate, a first electrically conductive layer on a surface thereof, and a first current modulating layer, the first electrically conductive layer having a sheet resistance to the flow of electrical current through the first electrically conductive layer that varies as a function of position.

A submersible sieve apparatus provided with an exoskeletal frame enveloping a filter element and a detached post-filter backing; positioned to strain a lotic stream of entrained sediment prior to or upon being deposited. The frame can positioned and manipulated for greater efficiency. The filter and backing will take the shape of the frame and the backing may or may not be attached.

Methods for restoring tidal areas adjacent to a tidal water area are provided. The method can comprise: pumping water from the tidal water area; and directing a high-pressure water stream, using the water pumped from the tidal water area, to the bottom surface of the tidal water area during an incoming tide period. The high-pressure water stream impacts the bottom surface of the tidal water area with sufficient force to dislodge sediment from the bottom surface into the tidal water area.

A modular wave-break includes a wall, a base attached to the wall, and an anchor attached to the base. The wall includes a set of dissipating holes integrally formed in the wall and a set of passage holes integrally formed in the wall. Reinforcing structural rods may be embedded in the wall, the base, and the anchor to provide strength. Mounting holes in the base enable the modular wave-break to be secured to a water bottom surface. Multiple modular wave-breaks may be interconnected to form a single wave-break. In an alternate embodiment, a water control structure provides for management of the water table of a wetland area. The water control structure includes a panel comprising a wall, a base attached to the wall, an anchor attached to the base, and a flow hole through the wall. Multiple panels are connected in series to create a water tight water control structure.
