A target based tidal flat wetland restoration method comprises: (1) determining a target, (2) constructing an ecological unit by microtopography transformation on the tidal flat wetland required to be restored, (3) applying biochar material and salt-resistant ecological material within the ecological unit, (4) performing waterfront plant configuration within the ecological unit. The restoration method uses the natural tidal ebb and flow to adjust water and salt conditions in the ecological unit (salt content is reduced by more than 80%) and maintaining the target water level (0-2 m), optimized the structure of soil microbial community (the abundance of soil bacteria has been increased by more than 200%), improved the germination rate and survival rate of plants during tidal flat restoration process (the germination rate has reached more than 90%, and the survival rate has been increased to more than 62%), enriched plant species in waterfront zone (12 species).

The present invention comprises a system for the localized heating of a portion of water within larger water bodies through a partial confinement of said portion of water without completely interrupting the water flow and where the concept of being in the same water body is maintained, in order to facilitate the practice of recreational activities in a heated environment. The present invention provides a solution to achieve a comfortable temperature of the water for direct contact recreational purposes in a cost-efficient manner, with a partial confinement system that allows creating a heat plug and provides for a serpentine-type flow between both sides of the partial confinement system.

A system and method for restoring wetland habitats and providing a platform on which indigenous and transplanted plant species can thrive. Water from a source, such as, stormwater run-off is captured and filtered through a combination of sand berms and riffle weirs to a series of aquatic beds, thus creating nutrient-rich environment.

An underdrain system includes a gasket positionable on a sealing surface and one or more underdrain laterals positionable on the gasket. At least one of the underdrain laterals has a gasket inspection hole therethrough. The gasket inspection hole is configured to: (i) have a gasket inspection tool inserted therethrough to verify that the gasket is sufficiently compressed between the sealing surface and the one or more underdrain laterals; and/or (ii) have a portion of the gasket extend therethrough when the gasket is sufficiently compressed between the sealing surface and the one or more underdrain laterals. The underdrain system may also include a gasket retention feature. Water level tests may be used to determine whether surfaces are level and/or whether relative heights are within acceptable tolerances.
