Coastal Flood Modeling Challenges in Defended Urban Backshores

A web GIS based integrated flood assessment modeling tool for coastal urban watersheds

Urban flooding has become an increasingly important issue in many parts of the world. In this study, an integrated flood assessment model (IFAM) is presented for the coastal urban flood simulation. A web based GIS framework has been adopted to organize the spatial datasets for the study area considered and to run the model within this framework. The integrated flood model consists of a mass bal...

Urban Growth and Flood Disasters in the Coastal River Basin of South-Central Chile (1943–2011)

Urban flooding is an increasing problem in developing countries, thus understanding flood dynamics is necessary to establish guidelines on urban development and flood management. This paper studied the lower reaches of the Andalien River basin, situated on the coast of the Greater Concepcion Metropolitan Area (CMA), the second most urbanized area in Chile. This basin experienced a record 21 flo...

Flood and Coastal Zone Monitoring in Bangladesh with Radarsat ScanSAR: Technical Experience and Institutional Challenges

n Bangladesh, river floods, monsoon rains, and tropical cyclones are an integral part of the annual hydrological cycle, regularly affecting the livelihood and well-being of more than 100 million people. During years of severe flooding, for example in 1987, 1988, and 1998, the country was transformed by intermittent inland seas that occupied as much as 60% of its land surface. Wide swath synthet...

Flood Modeling in the Coastal Plains and Mountains: Analysis of Terrain Resolution

The number of flood disasters has increased worldwide in recent decades. Identifying the optimal resolution or scale at which to represent digital terrain models DTMs is critical in order to improve our ability to accurately and efficiently model floods. Few studies have attempted to compare flood modeling results using different resolutions of DTMs in divergent environments. In this study floo...
