A new approach for urban flood risk assessment using coupled SWMM-HEC-RAS-2D model.

Journal of Environmental Management
Urban stormwater management is crucial for mitigating the impacts of flooding in urban areas, as it plays a vital role in protecting infrastructures, ensuring public safety, and preserving environmental quality.

Expert System for Calibrating Swmm

Journal of Water Resources Planning and Management, 1989
EPA'S Storm Water Management Model (SWMM) simulates all aspects of the hydrologic and quality cycles. Using expert system technology, an interactive user‐support framework has been developed to automate the calibration of the runoff block. It acts as a front end to assist the user in the initial estimation of the parameter values and in building the ...

New optimization strategies for SWMM modeling of stormwater quality applications in urban area.

Journal of Environmental Management
Build-up/wash-off models were originally developed for small-scale laboratory facilities with uniform properties. The effective translation of these models to catchment scale necessitates the meticulous calibration of model parameters.

swmm_api: A Python Package for Automation, Customization, and Visualization in SWMM-Based Urban Drainage Modeling

Water
The Python package swmm_api addresses a critical gap in urban drainage modeling by providing a flexible, script-based tool for managing SWMM models. Recognizing the limitations of existing solutions, this study developed a Python-based approach that ...

Coupling SWAT+ and SWMM Models to Quantify Streamflow in Mixed Rural–Urban Watersheds

Hydrological Processes
The fast‐paced urbanisation has resulted in urban–rural transitional zones known as ‘sprawl’ that exhibit both urban and rural characteristics. This transformation significantly impacts water balance, leading to changes in surface runoff patterns in ...

Performance assessment of sponge city infrastructure on stormwater outflows using isochrone and SWMM models

, 2021
Sponge city construction in China is integrated with stormwater management infrastructure, which is based on the concept of low impact development, such that the urban flooding and nonpoint storm pollution are mitigated.

Urban drainage efficiency evaluation and flood simulation using integrated SWMM and terrain structural analysis.

Science of the Total Environment
A method for evaluating urban drainage system efficiency and simulating pluvial flooding is presented, incorporating rainwater inlet limitations through an integrated SWMM and terrain structural analysis (the corrected model).

SWMM Model and Level of Discretization

Journal of the Hydraulics Division, 1981
The costs of setting up and running a storm water management model are largely determined by the level of discretization used for a particular catchment. This study investigates the level of discretization needed to adequately represent an urban watershed and to illustrate the effects of reducing the number of subcatchments on the accuracy of runoff ...

Hybrid SWMM and particle swarm optimization model for urban runoff water quality control by using green infrastructures (LID-BMPs)

, 2021
In the past decades, climate change, population growth, urbanization, changes in land-use, and outdated runoff collecting networks have affected the quantity and quality of urban runoff in many countries.

SWMM Stormwater Pollutant Washoff Functions

Journal of the Environmental Engineering Division, 1978
In the classical theory of elasticity, one of the celebrated methods for solving boundary value problems regarding an isotropic homogeneous linear elastic continuum is the method of Galerkin's vector. However, the set of governing equations to be solved is a system of N partial differential equations, N being the number of spatial dimension.
