Canals and small rivers-TECHNIQUES

From Dagnachew:

1. [ Treatment ]

Is there any way by which we can improve the edge conditions of these canals making them more accessible thereby reintegrating them to the city? is there any way by which we can reverse the polluted state of these canals?

2. [ Equipment ]

are there more efficient techniques to deal with the flooding problems than the water level regulation systems being employed now ? are ther alternative techniques that are more susatinable and less energy consuming ? such as replacing the "hard" or engineered solutions by "soft" or more flexible solutions ?

3. [ Management ]

Could we propose new ways of managing the canal systems, in such a way that it involves the people that reside alongside them? Is there a way by which we can raise their awareness about environmental issues and make them key role players in the sustainable upkeep of these canals systems?

From Marijn:

1. How can To Lich River be treated as to improve the relationship with its surroundings? Can there exist different relationships with urban and agricultural areas?

2. Can parts of the river bed be restored to bring a new quality to the urban environment?There are plans of reconnecting To Lich River to Red River (however in a way that is different from the historical course). What are the effects of a renewed connection of the small rivers and canals to the Red River?

3. Day River seems far away from the city, while Nhue River seems to be the next river to be swallowed. What should be the first steps to define the quality and character of Day River, imagining its gradual transformation? What can be learned from To Lich and Nhue River?
