Proposed is a wave-dissipating block including: a body placed on a seabed perpendicularly thereto and having a shape of a polygonal column, a cylinder, an oval column, or a cross-shaped column; male coupling protrusions formed on a first surface of the body in a height direction thereof and on a surface opposite to the first surface, respectively; female coupling grooves formed in a second surface of the body in the height direction thereof and in a surface opposite to the second surface, respectively; a habitat part configured as a space defined at a center portion of the body or a portion of the body; a dividing plate provided as a plate dividing the habitat part into habitat parts; a through hole formed in the dividing plate; and a space part having a space defined between multiple bodies of wave-dissipating blocks connected adjacently to each other.

An erosion control apparatus includes a flexible, container and a cord. The container includes a container upper side, a container lower side opposite the container upper side, a container trailing end, a container leading end opposite the container trailing end, and a container mouth toward the container leading end. The container mouth provides an opening to a container interior. The cord is attached between the container mouth and an attachment point toward the container trailing end. The cord draws the container mouth toward the container trailing end due to a length of the cord between the container mouth and the attachment point being shorter than a length of the container between the container mouth and the attachment point. The cord further draws the container mouth toward a closed position as sediment enters the container mouth, fills the container interior, and urges the container leading end away from the attachment point.

Embodiments provide a quay wall attachment and a method for promoting biodiversity in a marine environment. The quay wall attachment includes a quad plate and a module. The quad plate is secured to a portion of a quay wall located underwater. The module includes a coral module, a fish module, a plant module, and combinations of the same. The coral module includes living corals and is secured to the quad plate. The fish module includes a hollow space and is secured to the quad plate. The plant module includes living marine plants and a hollow space, and is secured to the quad plate.

Implementation of an excavated artificial beach (1) of running water, using water (9) captured from an external water body (2), of any origin, which is treated by a flotation/decanting system (20), the water (6) of the excavated artificial beach (1) being returned to the external water body (2).

The present invention relates to a dual-purpose flood and drought relief system for redirecting water from flooded areas to areas in need of water due to lack of supply and/or drought. The system is comprised of at least one pump that can be placed in a body of water. When flooding occurs, at least one water sensor is activated, such that the pump begins pumping flood water through the system. The system may be comprised of at least one filter that is preferably a multi-layered carbon filter. Using a hydroelectric and magnetic compass, the system redirects the flood water through a tubing/piping to deliver water to drought-stricken locations. The tubing may be installed in a plurality of locations such as, but not limited to, highways, roadways, railways, bridges, etc., to easily transport water using the system.

A flood barrier module that is light, easy to install, easy to remove or stow, and resistant to softening of underlying ground includes an inclined front wall penetrated by holes near a top thereof, as well as side walls, a rear wall, and a base wall, which together surround a substantially watertight interior. The module is initially anchored by its own weight and/or by stakes or similar means. When impacted by flood waters that rise higher than the holes, the module is filled with flood water that is retained within the interior, such that the weight of the retained water anchors it to the ground, even if the ground becomes softened. Embodiments can be folded or disassembled and stacked into a flat, stowed configuration. The module can be installed in a sump or pit, and can be at or below grade when stowed.

A flexible liquid separation media floats within an exterior liquid, e.g., body of water. At least three of a vertical outer support column are secured within the exterior liquid with upper connectors coupled to the flexible liquid separation media. A float within each of the at least three of a vertical outer support column are coupled to a lower portion of the flexible liquid separation media. The flexible liquid separation media is used to hold a contained liquid within the exterior liquid. The lower portion sinks and rises as the fluid level changes within the flexible liquid separation media while the floats within at least three of a vertical outer support column floatably anchors the lower portion and maintains the lower portion (105L) of the flexible liquid separation media (105) a consistent distance from the at least three of a vertical outer support column (120).

A specifying system according to the present disclosure includes an optical fiber (30) laid along a levee (20) of a river (10), a communication unit (41) configured to receive, from the optical fiber (30), an optical signal containing a pattern that changes according to a state of the levee (20), and a specifying unit (51) configured to specify a water level of the river (10) based on the pattern that changes according to the state of the levee (20).
