"Developing the IsoProbability Curves of Combination of Rainfall and Water Level for Urban Drainage Infrastructure Planning—A Case Study in Ho Chi Minh City"

"Developing the IsoProbability Curves of Combination of Rainfall and Water Level for Urban Drainage Infrastructure Planning—A Case Study in Ho Chi Minh City" by Giang Song Le and Hoa Thanh Thi Nguyen has been published in the Journal of Water Management Modeling.

This study introduces a novel methodology for constructing isofrequency curves that characterize the return periods of rainfall-water level R, H combinations, with direct applications for urban drainage planning and flood risk assessment. By applying this approach to five rain gauge stations in the inner-city area of Ho Chi Minh City, a set of isofrequency curves that provide critical insights into the relationship between rainstorm intensity and water level variations at drainage system outlets were developed. These curves serve as essential tools for defining boundary conditions in hydrodynamic models, thereby enhancing the accuracy of urban flood simulations and optimizing the design of surface water drainage infrastructure.
