Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure-type water conservancy systems fail to effectively regulate water levels without causing floods in upstream areas, droughts in downstream areas, and ecosystem damage, while also posing security risks and disrupting aquatic habitats.
Innovation Solution
A non-closure water conservancy system that includes a water storage system with multiple reservoirs and passages connected to a river/lake, allowing for the regulation of water levels through sluices and automatic overflow passages, enabling water storage during floods and release during droughts, and incorporating a hydroelectric system for energy generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If closure-type water conservancy system is used to regulate water level, then water storage capacity is improved, but ecosystem damage and security risks worsen
Solution Approach 1:
The water conservancy system is divided into multiple independent reservoirs (first precipitation reservoir, second precipitation reservoir, storage reservoir) connected by water passages. This segmentation allows water to be stored and regulated without complete river closure, maintaining ecosystem connectivity while achieving water storage capacity.
Solution Approach 2:
Water passages with sluices act as intermediaries between the river/lake and reservoirs, enabling controlled water exchange. This intermediary mechanism allows regulation of water levels while maintaining partial connectivity, reducing ecosystem damage compared to complete closure.
2Reliability
If closure-type water conservancy system is used to store water, then flood control in midstream and downstream is improved, but floods in upstream area worsen
Solution Approach 1:
Multiple reservoirs are segmented along the water flow path, with the first precipitation reservoir capturing upstream floodwater before it accumulates. This segmentation prevents upstream flooding while maintaining flood control reliability in midstream and downstream areas.
Solution Approach 2:
The first precipitation reservoir performs preliminary water storage at the upstream end, capturing excess water before it can cause upstream flooding. This preliminary action prevents the harmful effect of upstream flooding while maintaining overall flood control reliability.
3Quantity of substance
If closure-type water conservancy system is used to regulate water level, then water storage during flood is improved, but water release during drought worsens
Solution Approach 1:
The system maintains continuous water exchange between the river/lake and reservoirs through water passages with sluices. During drought, water can be continuously released from the storage reservoir to the river/lake, ensuring ease of operation and maintaining water levels without the disruptions caused by complete closure.
Solution Approach 2:
Water passages with controllable sluices serve as intermediaries that facilitate easy water release during drought. These intermediaries allow flexible operation, enabling water to be released from the storage reservoir to the river/lake as needed, improving ease of operation compared to closed systems.
4Stability of the object's composition
If non-closure water conservancy system is used, then ecosystem stability is improved, but water storage capacity worsens
Solution Approach 1:
The system uses multiple segmented reservoirs (first precipitation reservoir, second precipitation reservoir, storage reservoir) that collectively provide substantial water storage capacity. This segmentation maintains ecosystem connectivity while achieving sufficient total storage capacity through the combined volume of multiple reservoirs.
Solution Approach 2:
The water conservancy system employs a nested structure where multiple reservoirs are arranged in sequence along the water flow path. This nested arrangement maximizes water storage capacity within the available space while maintaining ecosystem stability through partial connectivity between reservoirs and the river/lake.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively regulates water levels without closing the river/lake, reducing flood and drought impacts, stabilizing ecosystems, and providing energy and irrigation benefits, while being suitable for urban and low-lying areas with wide shorelines.
Implementation Method 1
water from the river/lake enters into the water storage system when the river/lake level exceeds a warning level, thereby lowering the river/lake level... the river/lake is replenished with the water stored in the water storage system when the river/lake level is unduly low
Implementation Method 2
The high-capacity reservoir may also be designed with a hydroelectric system

AI summary
A method for river/lake level regulation and a water conservancy system. The method for level regulation employs a non-closure mode; a water reservoir system is built on one side of a river/lake, water from the river/lake enters into the reservoir system when the water level of the river/lake exceeds a warning water level, and the river/lake is replenished with the water stored in the reservoir system when the water level of the river/lake is unduly low; the conservancy system, which employs the non-closure mode, is built on one side of a river/lake waterway and includes the water reservoir system and a first water passage, the water reservoir system communicates with the river/lake waterway through the first water passage. The method for river/lake level regulation and the water conservancy system realize river/lake level regulation during drought and flood periods without any river/lake closure, so that water resources are control effectively.
