The saucer shape topography of the city ,release of water from Nepal into the rivers of Rapti and Rohin, degradation of water bodies, gentle topographic slope , unplanned development, poor infrastructure, local underground sewerage system , lack of solid waste management and changing trend of Climatic Change has increased the problem of occurrence of flood in Gorakhpur City. Water logging during monsoon season has become major problem in many parts of the city for the last few decades. Thus, It is easy to predict that if the present situation continues ,the people of Gorakhpur will have to face serious consequences in terms of livelihood, health and infrastructure in the future.
The city is ,naturally, vulnerable due to its physical attributes. Due to the frequent meandering of the River Rapti in the past, the topography of the city is badly affected. Some parts of South and South East of the Gorakhpur city go lower than the banks of river Rapti during monsoon season. At present ,nearly 18 percent , especially the southern, western and central areas of the city face acute water logging. In these areas ,water stagnates for more than three to four months, leading to adverse health conditions and increasing health hazards. Along with water logging, the city is also suffering from poor sanitation and solid waste management causing the unhygienic environment susceptible to water borne and vector borne diseases.
