Urbanization is the major demographic development which is occurring very fast and with larger magnitude in the developing countries. In many cases, specifically, in the poor economic countries urbanization is a demand driven unplanned and bottom up process, which transforming the existing landscape without considering the possible consequences and requirement for environmental sustainability. These urban growths have profound adverse effect on the water resources, particularly in the humid tropical region. In the tropical region where monsoon causes huge rainfall during some part of the year are naturally drains by the gravity drainage through stream-river networks, and wetlands works as natural retention storage.

Urbanization, particularly unplanned one, hampered this natural state of drainage, and hence causes sudden inundation and water-logging. However, hydrological consideration during urban planning can reduce the adverse effects through conservation of wetlands and stream-networks to be used as retention ponds and canals or designing such elements to drain-store-drain the modified landscape

This year, the world’s urban population of over three billion people, has for the first time in history exceeded the number of those living in rural areas. Going by this trend, by 2030 around two-thirds of the world's people will be living in cities. According to a July 2006 estimate, in India around 30 percent of the population lives in urban cities.
