Hydraulic Modeling beyond HEC-RAS

Impacts of Global Climate Change, 2005
A drainage swale hydraulic analysis was conducted by WEST Consultants, Inc. as part of a dispute regarding a proposed subdivision. The primary purpose of the study was to evaluate the adequacy of the proposed drainage improvements. The downstream portion of the flow system consisted of: a steep triangular channel discharging into a debris basin, a ...

Common Modeling Mistakes Using HEC-RAS

World Environmental and Water Resources Congress 2007, 2007
The U.S. Army Corps of Engineers River Analysis System (HEC-RAS), developed by the Hydrologic Engineering Center, has long been the standard for one- dimensional hydraulic modeling. Despite the wide spread use of the program, even seasoned engineers can fall victim to some common modeling mistakes using HEC-RAS.

Flood Assessment Using Hydrodynamic HEC-RAS Modelling

2022
River flooding causes several human and financial casualties, and hence, it is necessary to perform research studies and implement subsequent actions consistent with the nature of the river. To minimize flood damage, floodplain zoning is a prominent non-structural measure in planning the areas surrounding the river.

Dam and Levee Breaching with HEC-RAS

World Water & Environmental Resources Congress 2003, 2003
With the release of HEC-RAS 3.1 (November, 2002), users can now perform dam and levee breaching analyses. This paper discusses the methodology used to perform the breaching, as well as the available options. The data required to perform such an analysis is reviewed, and available output from the model is displayed.

HEC-RAS yardımıyla bir menfezin hidrolik analizi

2018
Menfezler, akarsu üzerinden ulaşım yolları oluşturmak için çok eski zamanlardan beri başarıyla uygulanmış sanat yapılarıdır. Tarihi çok eskilere dayanan menfez yapımı, akarsularda üzerine inşa edilerek, yaya ve taşıt geçişleri için güvenli bir koridor sağlamaktadırlar.
