A tsunami-wave structure is provided for installation in the bottom of the sea/ocean in the near-shore area which is exposed to the air at the time of a low tide that precedes the arrival of tsunami. Normally, the structure is immersed in water and when exposed to air before arrival of the tsunami wave assumes a tsunami-wave dampening position under the effect of its own gravity. This is achieved by making the structure in the form of a two-lever mechanism having two lever arms separated by a fulcrum point with a counterweight attached to the end of one the lever arms and a tsunami-wave breaker pivotally connected to the end of the other lever arm so that when the structure is exposed to the air the tsunami-wave breaker is turned down and allows the counterweight to outweigh the tsunami-wave breaker and to raise it to the operation position.

A water supply control system is disclosed that comprises a computer-implemented control system coupled to a plurality of gates, one or more pumps, and a plurality of sensors. The computer-implemented control system is configured to receive a request to transfer excess water from a non-water supply lake to a water supply lake and determine, based at least in part on data from the plurality of sensors and geographic locations of the non-water supply lake and the water supply lake, whether transferring water as requested will cause or worsen a flood event. In response to a determination that transferring water as requested will not cause or worsen a flood event, the computer-implemented control system is further configured to issue a command to cause a gate associated with a dam at the non-water supply lake to open such that water is transferred from the non-water supply lake to the water supply lake.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

A fluctuation belt ecological slope protection system that responds to hydrological variation includes a runoff treatment system and an ecological floating island system. The runoff treatment system includes a grass planting side ditch and a water accumulation pit-pond. The ecological floating island system includes an ecological floating island and an ecological gabion base. The ecological floating island includes a flexible substrate, and aquatic plants. The ecological gabion base is positioned below the ecological floating island. The ecological protection system is suitable for a fluctuation belt and consists of a runoff treatment system and a separable ecological floating island system. Rain water on bank slope is purified and collected as wet soil is stabilized, the protection system responds to backwater water level variation in fluctuation belt, providing growing space for plants, organisms, and fish, following variation in water level, enriching the ecological environment of the fluctuation belt, and improving scenic effect.

“PROCESS OF IMPLEMENTATION OF ARTIFICIAL WATER BEACH CURRENT FOR RECREATION”, intended for the implementation of a beach excavated artificial water (1) for recreational and contemplative use, using water captured (9) from an external water body (2), of any which will be treated by the flotation/decanting system (20), without the the need to use filters and without the need for recirculation of the (6) from the interior of the excavated artificial beach (1), and the water (6) the excavated artificial beach (1) is returned to the external water body (2) in better condition than the water that was captured (9).
