Can dredging and cleaning rivers actually prevent waterway clogging?

Question

Accepted Answer

Dredging and Cleaning Rivers Can Mitigate Waterway Clogging

Dredging and cleaning Jakarta's rivers and waterways are recommended actions to address the causes of waterway clogging. These efforts are aimed at improving the capacity of the remaining waterways, which has been reduced by sedimentation, poor waste management, and illegal settlements. The objective is to prevent these waterways from becoming blocked, particularly during periods of heavy rainfall.
Addressing Sedimentation and Waste Management

The capacity of Jakarta's rivers has diminished due to accumulated sediment and inadequate waste management practices. These factors contribute significantly to the obstruction of water flow, especially when rainfall intensifies. By undertaking regular dredging and cleaning, authorities aim to remove these impediments and restore the rivers' ability to channel water effectively.
Reducing Reliance on Groundwater Extraction

In conjunction with river maintenance, there is a need to help communities access water without resorting to excessive, uncontrolled groundwater extraction. This over-reliance on underground aquifers exacerbates the problem by causing the city to sink annually by 5-10 cm. A comprehensive approach would involve improving surface water management alongside efforts to curb groundwater depletion.
Implementing Nature-Based Solutions

Beyond traditional infrastructure interventions like dredging, there is a growing consideration for nature-based solutions. These approaches include transforming concrete drainage systems back into natural floodplains. Such strategies are part of a broader effort to manage water more sustainably and in harmony with natural processes, thereby contributing to the overall resilience of the city's water management system.
