The formation of urban coastal flooding is mainly ruled by the interaction between rainfall-runoff and storm surge. This study aims to advance the understanding of coastal urban flood mechanism by developing an integrated modeling and multivariate analysis framework, which involves a hydrologic mode...

Urban flooding in Chittagong City usually occurs during the monsoon season and a rainwater harvesting (RWH) system can be used as a remedial measure. This study examines the feasibility of rain barrel RWH system at a distributed scale within an urbanized area located in the northwestern part of Chit...

Storm-surge modelling in the northern Bay of Bengal still remains a challenge due to the complex tidal nature and poor observational coverage. In this study, using satellite information, a coupled modelling system was developed which comprises Delft3D-Flow and simulated wave nearshore to simulate th...

The salinity distribution in the estuarine channel network of a partially mixed estuary was investigated by quantifying salt intrusion length and stratification with response to tidal circulation, seasonal variation, topography, and river discharge. The studied Karnafuli River estuary responds to a ...

This study presents a topography-dependent error adjustment technique for observed spatial rainfall estimate (OSRE) with the application of a multivariate t-copula model in a sparsely gauged region in Bangladesh. Multiple satellite precipitation products, including TRMM-3B42v7, TRMM-3B42RT, IMERG-Da...

Low lying coastal cities are under high risk of the compound flood with frequent storm surge occurrence and sea-level rise. This study attempted to develop a hybrid modeling framework to simulate various physical process of the compound flood. In this regard, first, the storm surge process is simula...
