Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing levee systems, particularly those made of earthen embankments, face issues such as rapid deterioration due to water motion, subsidence, and lack of structural support, leading to instability and high maintenance costs, making them ineffective for long-term water control and containment, especially in emergency or repair situations.
Innovation Solution
A modular levee and barrier system comprising a prism-shaped outer shell with end and side walls, featuring a module-to-module connection system and anchor plates for stability, allowing for easy assembly and expansion, and filled with filler material to provide structural integrity and adaptability to varying terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If earthen embankments or levees are used for water control, then they are economical to install, but they deteriorate rapidly due to water motion and lack structural protection
Solution Approach 1:
The levee system is divided into modular components (panels, sections) that can be independently manufactured, transported, and assembled. Each module contains structural elements (steel reinforcement, geomembrane lining) that provide durability while the modular nature maintains economical installation through standardized fabrication and quick assembly.
Solution Approach 2:
The levee structure combines multiple materials with complementary properties: steel components for structural strength and stability, geomembrane for water impermeability, and soil/earth for economical fill material. This composite approach achieves both durability and cost-effectiveness by assigning each material its optimal function.
2Ease of manufacture
If earthen levees are constructed, then initial installation is economical, but maintenance costs increase over time due to deterioration
Solution Approach 1:
The modular levee design incorporates protective elements (geomembrane lining, steel reinforcement, drainage layers) during initial construction to prevent deterioration before it occurs. This proactive approach reduces future maintenance needs by addressing potential failure points in advance, thereby reducing long-term time and cost losses.
Solution Approach 2:
The modular construction allows individual sections to be replaced or repaired independently without dismantling the entire levee. Damaged modules can be removed and replaced efficiently, minimizing maintenance downtime and costs while preserving the overall structure.
3Reliability
If earthen levees are built, then they provide basic water containment, but they require a wide base to ensure stability
Solution Approach 1:
The integration of steel reinforcement and geomembrane-lined modules provides structural strength that allows the levee to achieve stability with a narrower base compared to traditional earthen levees. The steel components bear the structural loads while the geomembrane prevents soil erosion, reducing the required base width.
Solution Approach 2:
The levee design transitions from relying solely on horizontal base width for stability to incorporating vertical structural elements (steel reinforcement, multi-layer construction) that provide stability in the vertical dimension, thereby reducing the required horizontal footprint.
4Strength
If sheet piles are driven into earthen embankments to form a floodwall, then more structure and stability are provided, but the base remains wide and difficult to construct in limited spaces
Solution Approach 1:
The system combines steel panels with soil and geomembrane materials to create a composite structure that achieves high structural stability without requiring a wide base. The steel components provide the necessary strength while the soil-geomembrane composite system optimizes the base footprint.
Solution Approach 2:
The floodwall is constructed from segmented modular panels that can be assembled in narrow spaces and limited areas. This modular approach provides the structural stability of sheet piles while adapting to constrained geometries where traditional wide-based floodwalls cannot be constructed.
5Reliability
If traditional levees are constructed, then they provide basic protection, but they cannot be easily built or repaired during flooding or emergency situations
Solution Approach 1:
The levee system is divided into pre-fabricated modular sections that can be rapidly transported and assembled during emergencies or flooding events. This segmentation enables quick deployment and emergency construction without requiring extensive on-site manufacturing, thereby improving ease of operation during critical situations.
Solution Approach 2:
Levee modules are pre-fabricated with structural elements (steel reinforcement, geomembrane lining) before deployment. This preliminary preparation allows for rapid assembly during emergencies, as the critical structural components are already in place, eliminating the need for time-consuming on-site construction activities.

AI summary
A levee and barrier module for fluid control and containment is provided including an outer module shell and a module-to-module connection system to attach adjacent outer shells. The outer module shell, being in the general shape of a prism or prism with curvilinear section, is formed by opposing side walls and two opposing end walls, and is configured to enclose or support filler material. The two opposing end walls are configured with end apertures. The outer module shell defines a top aperture and a bottom aperture. When modules are placed end to end in a levee structure the end apertures allow filler material communication horizontally between adjacent modules. The bottom aperture allows filler material communication with the earth below the module. The top aperture allows filler material to be added to the module, as well as visual observation of, and maintenance of, the amount of contained filler material.
