Integrated Storm Water Management – An Approach for Urban Flooding In Hyderabad, India

摘要

Flooding in general and urban flooding became common even t in world and in India. Un-even distribution of rain fall coupled with rapid and unplanned urbanization, encroaching upon and filling up natural drainage channels and urban lakes to use the high-value urban land for buildings are the cause of urban flooding. The illegal filling of urban water bodies in cities like Calcutta, Delhi, and Hyderabad etc. is a unchecked. Storm water management has become complex phenomenon especially in urban scenario where land costs are high. Especially in cities like Hyderabad, India, where unplanned settlements are more common in low laying areas which are water bodies once upon time. Integrated stormwater management is simply thinking about all of the factors that somehow affect precipitation as it moves from the land surface to an eventual receiving water. It is the process of accounting for all of these factors (e.g. rate, volume, quality, ground water impact) in a logical process so that inadvertent mistakes are not made that could eventually harm a resource. In Integrated Stormwater management by prioritizing goals and actions (ideally through consensus) provides a road map for moving towards a target condition by identifying the interconnected nature of goals, values and expectations, risks and opportunities, what needs to be done to manage the risks and achieve the opportunities, who should be responsible, a general timeline for implementation.
