RISA Simple and Efficient Method with Godunov-Type Schemes for Flow Simulation at Junctions of Open Channel Networks
Publisher: American Society of Civil Engineers
Abstract: This paper presents a numerical model for simulating flows in open channel networks by discretizing the Saint-Venant equations via a Godunov-type scheme. The methodology integrates the Harten Lax van Leer (HLL) approximate ...
An Online Data-Driven Evolutionary Algorithm–Based Optimal Design of Urban Stormwater-Drainage Systems
Publisher: ASCE
Abstract: To reduce flood risk in urban areas, an optimal design of drainage networks for urban areas is essential for flooding control and drainage management of the urban stormwater drainage system (USDS). A conventional design ...
Multisurrogate Assisted Evolutionary Algorithm–Based Optimal Operation of Drainage Facilities in Urban Storm Drainage Systems for Flood Mitigation
Publisher: ASCE
Abstract: Drainage facilities are key infrastructure elements of urban stormwater drainage system (USDSs) for flood mitigation during short-duration extreme rainstorms. To obtain the optimal operation rules of drainage facilities ...
Approximate Method for Evaluating the Drainage Process of an Urban Pipe Network with Unavailable Data
Publisher: ASCE
Abstract: Because drainage network data is unavailable in many urban areas, the accuracy of urban flood simulation may be reduced. A linear reservoir method is proposed to characterize the drainage capacity of a pipe network, and a ...
