Abstract
Urban flooding is the inundation of land or property in a designed atmosphere, significantly in additional densely inhabited areas, caused by precipitation overwhelming the capability of drain systems, like storm sewers. Due to expeditious increment and improper urban designing the probabilities of creek, localized or flash urban floods have drastically multiplied. This study explores the application of Storm Water Management Model (SWMM) to densely populated area of Vijayawada city, which is fragmented into 58 sub-catchments. The study area is delineated in SWMM by the assistance of blueprint AutoCAD maps showing drainage network and Reference Level details. From this elaborated elevation data of drain networks, the flow direction has been evaluated to create the descriptive view of the area in SWMM. In this study area 2016, 2017 and 2018 extreme rainfall events of 24 hrs interval is considered for runoff analysis. The focus of the current wok is to model runoff conditions by applying Dynamic wave equation for routing floods and Green-Ampt equation for infiltration in SWMM. The model outputs guided in visualizing the runoff from extreme precipitation events and to analyze the accuracy of the storm water network system.
Highlights
India is highly vulnerable to various natural disasters such as, Floods, Cyclones, Droughts, Landslides, etc
The districts of Krishna, Guntur( Krishna river), West and East Godavari (Godavari river) along with cities and towns like Vijayawada, Guntur (Krishna river), Eluru, Machilipatnam, Bhimavaram, Rajahmundry, Kakinada(Godavari river) and some parts of Nellore(Penna river) on the east coast has been marked as Flood hazard zones map issued by National Disaster Management Authority (NDMA).In this study, we have considered the area of densely populated area of Vijayawada city, Andhra Pradesh
The present study is mainly focusing on runoff through Urban sub catchments of Vijayawada City, Andhra Pradesh, India where the excess runoff is a major concern to the environment due to dense population [7]
Summary
India is highly vulnerable to various natural disasters such as, Floods, Cyclones, Droughts, Landslides, etc. To control flooding situations Storm Management is done by diverting the flow of excess water These techniques helps in attaining sustainable development without increasing the vulnerability to flood [4]. The Land Surface that is delineated through Sub catchments It is getting precipitation from the Atmosphere within the sort of rainfall and it sends outflow within the kind of infiltration to the bottom levels and as surface runoff and waste material loadings to the Transportation. The Surface runoff is infiltrating mainly to higher soil root zone depth of the surfaces which are permeable in nature instead of area which is impervious. The present study is mainly focusing on runoff through Urban sub catchments of Vijayawada City, Andhra Pradesh, India where the excess runoff is a major concern to the environment due to dense population [7]
