What is the best solution for the drainage of a large groundwater ascending in an urban environment where the classic drainage is not effective.
We see this problem a lot in southern Algeria
Field work and related exercises are necessary to help the problem.
Exactly Virendra Kumar Saxena Need to study the soil and the run-off before recommending a solution.
It might be possible to use it to create attractive water features, such as fountains. However, if the increase in level is still a problem, steps may need to be taken on a larger scale to divert water from entering that area of groundwater. This could involve water basin trading so that water is sent to a different basin. However, this could just pass the problem to another area without fixing it.
This sort of problem is a good example of why Integrated Water Management is important. Each issue should not be viewed in isolation, but how it fits into the big picture of drainage and water supply strategies. Possibilities for groundwater utilisation should be explored, before simply trying to dispose of it.
This is indeed an opportunity for IWRM, assuming this is common during the rainy season, urban agriculture could be possible during the dry season. Land planning could again come in to allow both groundwater recharge and discharge points.
Mostly the risk with such conditions will go to structures and construction standards should help protect people and their environment.
Urban planners from all over the world are facing a great amount of challenge because of the increasing trend of urban flooding in recent days. More than half of the world population currently lives in urban areas, and over 500 cities shelter more than one million people worldwide (United Nations 2010).
Issue of urban flooding is addressed by many researchers in recent years, and some of the work can be referred:
