Elevated Aqueduct System for Flood Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flood mitigation measures are inadequate in addressing excess rainwater and overflows along existing river or drain paths, particularly in areas prone to heavy downpours, as they do not directly manage excess water volumes effectively.
Innovation Solution
The implementation of an elevated aqueduct system that links rivers, lakes, reservoirs, and seas, with aqueducts positioned above ground level or extending upward from river sides, allowing for increased water holding capacity and diversion of excess water through bridge-like structures, pumps, and floodgates to discharge water above high tide levels, thereby preventing backflow and floods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flood mitigation structures (monsoon drains, floodwalls, dams) are constructed, then flood defense capability is improved, but they do not directly manage excess water volumes along existing river or drain paths
Solution Approach 1:
The patent introduces elevated aqueducts that operate in a vertical dimension above ground level, allowing water to be diverted and managed at heights that bypass conventional ground-level drainage limitations. This dimensional change enables direct management of excess water volumes along river paths while maintaining flood defense capability.
2Area of stationary object
If river mouth is extended through land reclamation, then land area is increased, but discharge rate of river is reduced due to gentle gradient and narrow straits
Solution Approach 1:
The elevated aqueduct acts as an intermediary structure that creates an alternative water discharge pathway. By operating above ground level with steeper gradients, it mediates between the land reclamation needs and the requirement for maintaining high discharge rates, bypassing the constraints of extended river mouths.
3Volume of stationary object
If sea level rises during high tide, then water holding capacity is reduced, but conventional structures cannot discharge water above sea level
Solution Approach 1:
The elevated aqueduct system operates in a vertical dimension above high tide sea levels, allowing continuous water discharge even when sea level rises. This dimensional elevation maintains both water holding capacity upstream and reliable discharge capability to the sea during high tide conditions.
4Object-affected harmful factors
If strong evening winds blow from sea to inland, then wave height increases and river discharge capacity is reduced, but conventional structures cannot counteract this backflow
Solution Approach 1:
The elevated aqueduct serves as an intermediary discharge structure that operates independently of ground-level wind and wave conditions. By positioning the discharge point above high tide levels, it mediates against the harmful effects of strong evening winds and waves, maintaining river discharge capacity when conventional ground-level structures fail.
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
The system effectively mitigates flood risks by ensuring unidirectional water flow from land to sea, enhancing water retention and diversion capabilities, and utilizing excess water for irrigation, groundwater recharge, and recreational purposes, while supporting traffic and boating activities.
Implementation Method 1
the first section are positioned at higher than the other section, and the aqueducts or channel are configured to be placed above ground level... such that invert levels of the aqueducts or drains are higher than sea levels during high tide flooding

AI summary
A system for flood water or water flow mitigation includes at least one aqueduct or drain having a first section linking a river, lake, reservoir, water retention pond or dam to another section linked to another lake, reservoir, storage tank or sea, characterized in that the first section are positioned at higher than the other section, and the aqueducts or drains are configured to be placed above ground level or extend upward from sides of river or existing drain, such that invert levels of the aqueducts or drains are higher than sea levels during high tide flooding or sea level increases.
