A system and method to provide water and sediment flow through a dam or rock jetty, including a plurality of flow pipes positioned through the dam or jetty to receive water carrying sediment and a principal flow pipe to receive flow from the plurality of flow pipes and to deposit water and sediment a predetermined distance to the rear of the dam or jetty. A continuous trough may be mounted on the jetty forward face to efficiently capture water and sediment at entrances of the plurality of flow pipes. A system and method is also provided to suppress wave action against a shoreline and to collect sediment to build up the shoreline, comprising shelves extending out from a front wall of each body section, below a plurality of flow pipes, the shelves for shearing a wave and dispersing and using wave energy to direct sediment through the flow pipes.

In a method for reducing erosion on land where moving water has formed at least one rill or gully a plurality of rock-filled mesh bags are placed at selected spaced apart locations in a rill or gulley. The mesh bags have side walls in which there are openings, each opening having a major diameter of between inches and inches and a minor diameter which is less than or equal to the major diameter. For most uses, the mesh bags contain rocks having a size in which a largest diameter of the rock is between inch and 1 inch, and the mesh bags weigh between 3 pounds and 4 pounds. Water flowing in the gulley will pass through each mesh bag. The mesh bag reduces the flow rate of the moving water. Larger sizes of stones and bags are used for areas of greater flow.

The present invention relates to a gabion deployment platform for storing a folded multi-compartment gabion and from which the gabion can be deployed, the deployment platform comprising: a base element for supporting the folded multi-compartmental gabion, the base element comprising a first member configured to extend along at least a part of a first side of said folded multi-compartment gabion, and a second member, extending transversely from said first member, said second member configured to extend along at least a part of a second side of said folded multi-compartmental gabion; and at least one retaining element, coupled at a first end thereof to said base element, said at least one retaining element being releasably attached, connected or retentively engaged, at least at one point of said at least one retaining element, by way of at least one releasable attaching, connecting or retentive engaging means, to a portion of a compartment of said folded multi-compartment gabion, said at least one retaining element configured to extend from said base element, over at least a portion of said folded multi-compartment gabion, said at least one retaining element serving to attach, connect or retentively engage a part of the gabion to the base element when the gabion is folded but to release the gabion from the base element when the gabion is deployed.

A plurality of structural units for construction of eco-friendly structures in a body of water. A plurality of structural units comprises a primarily calcium carbonate material, preferably obtained from once living material from an organism, and a cement that is capable of holding the primarily calcium carbonate material. The plurality of structural units are of variable size and shape and are obtained by breaking up a larger portion of a composition formed by combining the primarily calcium carbonate material and the cement to hold the primarily calcium carbonate material.

A water extraction system including a water well coupled to an aquifer, a distribution line in communication between the water well and a use element, and a pump coupled to the water well for moving water from the water well to the use element at a pump rate. A well sensor and associated well mote collect water level data and upload the collected water level data to a server. A communication device is coupled to the server and an application carried by one of the server and the communication device calculates the rate of recharge of the well from the collected water level data. A pumping strategy is developed by the application using the recharge rate to determine an altered pump rate.

A river training structure includes a longitudinal groyne placed in the river. The groyne extends in flow direction of the river with water of the river along both longitudinal sides of the groyne. The river training structure includes blocks, each block being constituted by a central part and four or more legs extending from the central part such that the central part and legs define a three-dimensional configuration allowing a multiple of said blocks to inter-engage with each other three-dimensionally when stacked onto each other. The groyne is constructed from a multiple said blocks irregularly stacked onto each other and engaging with each other to form a dam body of inter-engaging blocks, the dam body having a longitudinal slope at the navigation channel side of the dam body.
