From September 2008 to June 2010 we carried out a strategic review of Hydro-Meteorological Monitoring networks operated by the Office of Public Works in Ireland.
RATING CURVE HEC RAS SOFTWARE
As well as a comprehensive review of the existing network and assessment of requirements to meet future initiatives, software tools for and guidance on network management were developed. The work was undertaken in two phases: i) River Gauging Network, ii) Rainfall Gauging Network. From January 2007 to September 2010, we carried out an extensive national review of the hydrometric network in England and Wales on behalf of the Environment Agency.We have an impressive track record in relation to delivering strategic hydrometric studies: The course price is £600 (+VAT) per attendee.įor more information about training courses provided by JBA Consulting, visit our dedicated Training Course page.

The output from the modelling has been used to inform the decision-making process in relation to flood hazard planning and flood alleviation scheme appraisal. He has produced models for clients such as The World Bank, Environment Agency and Network Rail. Gavin has undertaken a wide range of studies utilising the functionality of HEC-RAS. Gavin is one of our senior modellers based in our Skipton office. By the end of these training modules you will be able to:Ībout the trainer – Gavin Hodson, BSc FdSc MCIWEM C.WEM Throughout the course you will build on real world examples to understand and demonstrate the capabilities of the software. The course will then move on to cover 1D-2D hydrodynamic hydraulic models and RAS Mapper.
RATING CURVE HEC RAS HOW TO
This course will introduce you to HEC-RAS software and how to construct a simple 1D model, including the consideration of structures such as weirs, bridges and culverts within HEC-RAS, and floodplain representation. No prior knowledge or experience of HEC-RAS is required, although some knowledge of river modelling/hydraulics will be beneficial.

Project managers, engineers and hydraulic modellers requiring an overview of the HEC-RAS software and practical tuition on the use of HEC-RAS. HEC-RAS essentials – Book your place here This two-day course is tailored to give attendees an essential overview of the hydraulic modelling software HEC-RAS. The course modules will cover how to construct a simple 1D model including structures such as weirs, bridges and culverts, to developing a 1D-2D hydrodynamic hydraulic model. And this is not the same as using a stage-discharge curve to define the reservoir.Don’t miss our upcoming hydraulic modelling software training course: HEC-RAS essentials. However, the weir equation will be used to define flow through the breach-in addition to any other outflow you may have at the dam. This can be used to describe a complicated gate strcture or spillway-one that is not available explicitly in HEC-RAS. That way you could avoid modeling the reservoir in HEC-RAS altogether.Ī family of stage-discharge curves (rating curves) CAN be used at the inline structure to define flow through the structure prior to the breach. You also have the option to determine your breach hydrograph external to HEC-RAS and just enter it as the upstream boundary to a cross section. A storage area can also have a lateral inflow hydrograph attached to it. If you use a storage area to define your reservoir (level pool drawdown routing), then a simple stage-storage curve is required. If you use cross sections to define your reservoir (full dynamic hydraulic drawdown routing), then you can use an inflow hydrograph at the upstream-most cross section. My guess is this is why HEC-RAS does not allow for a stage-discharge curve to be used to define a reservoir.

Though this is an easy and stable way to define a reservoir, it lacks the ability to account for submergence effects, which could significantly affect the results once the breach has fully developed. In the NWS DAMBRK model, a single stage-discharge curve could be constructed external to the program and used as a method for defining the reservoir.
