A stable and variable design of a drainage structure includes a drainage body (11) and a cover (20). The cover (20) has engagement devices (13, 13′; 14, 14′; 23, 23′) when seen in a longitudinal direction of the drainage body (11), whereby the cover connects upper edges (12, 12′) of the drainage body (11) to one another transversely to the longitudinal direction in a tension-resistant manner over the entire length of the drainage body. In order to allow the use of different covers (20) for different loads, for example while using the same drainage body (11), two types of engagement devices (13, 13′; 14, 14′) are provided on the drainage body.

A culvert pipe inlet arrangement includes a pan member and an inlet that is configured to be disposed within a culvert pipe is disclosed.

A box culvert assembly and method of forming a box culvert assembly. The boxes forming the assembly comprise portions configured to allow pivoted assembly of one box into another, while reducing the likelihood of high stress or fracture. The box assembly further allows for a generally tight seal between the boxes.

Protection of upland areas adjacent to a variety of water body shorelines from flooding events by combining modified drainage culverts with and hidden by natural ecosystem flood attenuation environments.

A method for managing the flow of water beneath a ground surface uses modules. Assemblies of such modules are disclosed. The modules include supports and a deck portion, and the supports are spaced apart and form multiple channels with a main section of the deck portion. The deck portion also includes at least one section extending from a main section.

Embodiments of the present invention are directed to a low-profile solar-powered flood control device suitable for use on public roads, sidewalks, parking lots, and similar areas subject to pedestrian and vehicle traffic comprising a two-part housing with a low-profile cover and a mounting plate, a solar panel, a battery, a controller, a pump unit, inlet holes, inlet filters, a hose, and pump-hose connections. The low-profile cover is provided with separate battery and pump compartments to isolate the battery and controller from the pump unit and any water drawn into the housing. The flood control device may include a sensor for detecting the presence of water and turning the pump unit on and off. The controller is connected to the solar panel and the pump unit and may be configured to optimize battery charging for poor or indirect lighting conditions.

Structures, systems, and methods for controlling water flow in relation to an underpass space of a road support structure, including a method comprising receiving precipitation forecast data; receiving water volume data for water flowing toward an underpass space of a support assembly underlying a road, wherein a first culvert is positioned through the underpass space and a second culvert positioned around the support assembly configured to transfer water around the support assembly, and wherein one or more barriers are positioned to control flow of water within the first and second culvert; predicting water volume input to the underpass space based on the water volume data and the precipitation forecast data; and controlling the position of the one or more barriers to control flow of water within the first culvert and the second culvert based on the predicted water volume input.

A box culvert is disclosed having a top panel, a first side panel, and a second side panel, and a base panel. The first side panel and second side panel extend from the top panel to the base panel. The base panel is configured to have a plurality of sealed holes. The sealed holes are configured to be unsealed. Installing the box culvert in a riverway allows a road or trail thereover, and water passage therethrough. Opening of a specific amount, position, and size of sealed holes creates unsealed holes in the base panel. The unsealed holes allows groundwater upwelling therethrough, configured specifically to the waterway. The upwelling caused by removal of the specific plugs promotes aquatic habitat, contributes to water quality improvements, and ameliorates disruption from the insertion of the box culvert.
