Supporting the Design of On-Site Infiltration Systems: From a Hydrological Model to a Web App to Meet Pluriannual Stormwater Volume Reduction Targets
(ASCE, 2024/06/01)Infiltration-based sustainable urban drainage systems (i-SUDS) often turn out to be simple and effective solutions for on-site runoff and pollution control. Their ability to limit the discharge to sewer networks or receiving ... -
Seasonal Salinity Trends in Central and Southern Biscayne Bay, Florida
(ASCE, 2024/06/01)Salinity in estuaries varies naturally due to tides, weather, geomorphology, freshwater flow, climate, and sea level. Before the 1950s, water management in southern Florida focused on diverting freshwater to the ocean to ... -
Green Infrastructure for Sustainable Stormwater Management in an Urban Setting Using SWMM-Based Multicriteria Decision-Making Approach
(ASCE, 2024/02/01)A study is presented for the assessment of different stormwater green infrastructure (SGI) for sustainable stormwater management, both stand-alone and in combination, in the rapidly developing city of Gurugram, India. A ... -
A New Empirical Formulation of the Areal Reduction Factor for Design Rainfalls Applied to the Umbria Region in Central Italy
(ASCE, 2024/04/01)A reliable estimate of the areal reduction factor (ARF), useful for implementing the upscaling procedure of point rainfall information, is of crucial relevance in many hydrological applications aimed at hydraulic structures ... -
Testing the Multivariate Hüsler–Reiss Model as a Practical Parametric Approach for Multiple River Flood Risk Assessment Using d4PDF Data: A Case Study in Kyushu Island, Japan
(ASCE, 2024/06/01)Compound flood disaster risks are increasing due to multiple river floods within a single storm event. Many studies targeted dependence structure based on multivariate extreme value theory; however, fewer studies focused ... -
An International Perspective on the Selection of Inflow Design Flood
(ASCE, 2024/02/01)Inflow design flood (IDF) is selected following certain guidelines or criteria for hydrologic dam design. Fundamental to the development of these guidelines is the classification of dams and consequences of failure thereof. ... -
Nonstationary Seasonal Design Flood Estimation: Exploring Mixed Copulas for the Nonmonotonic Dependence between Peak Discharge and Timing
(ASCE, 2024/02/01)The seasonal design flood (SDF) plays an important role in guiding water resources management and floodwater utilization. To estimate the SDF, studies have established the joint distribution of flood peak (i.e., annual ... -
Time-Varying Evaluation of Compound Drought and Hot Extremes in Machine Learning–Predicted Ensemble CMIP5 Future Climate: A Multivariate Multi-Index Approach
(ASCE, 2024/04/01)Compound extremes can be expressed as the joint distribution or dynamic interaction of multiple variables and the interdependence of several extremes that have major effects on the agricultural sector. Analysis of these ... -
Applicability of Zero-Inertia Approximation for Overland Flow Using a Generalized Mass-Conservative Implicit Finite Volume Framework
(ASCE, 2024/02/01)The zero-inertia approximation of the shallow water equations has been observed to provide reasonably accurate results for various flood propagation problems. The commonly adopted explicit time schemes in the numerical ... -
