If testing highlights sensitivity to particular uncertainty, you may need to collect more data, such as installing a flow gauging station. You could complete further tests on initial conditions , grid resolution and model simulation parameters. Referring more generally to flood risk management rather than specifically hydraulic modelling , the latest EA guidance on accounting for residual uncertainty suggests the following stages to assess uncertainty.

Identify all primary sources of uncertainty and their components. An example for a fluvial model would see water levels as the primary source of uncertainty, with flow, hydraulic roughness and downstream boundary conditions plus others as components of this uncertainty.

You should account for uncertainty, for example, SC accounting for residual uncertainty: an update to the fluvial freeboard guide describes how designers increased the size of a flood storage area to account for the inflow hydrology having underestimated storm duration. Estimate the size of the residual uncertainty. Depending on the available information and project scale, this can be based on expert judgement or a more detailed analysis, as outlined in SC This can give insights into which inputs are most important and where to target efforts to address residual uncertainty.

This process is commonly adopted in hydraulic modelling projects. Hydraulic models can show mathematical instability where significant oscillations or mass balance errors the artificial gain or loss of water occur.

A stable model does not show instability. You can make a model stable if you can discount instability as it occurs at a location or time beyond the focus of the project. You should try to reduce model instability where you can, but this should be proportionate to considering other uncertainties. The FDG suggests that to reduce the risk of instability, you should follow these steps to build your model:. Your approach to addressing instability will vary depending on model type, model software and local characteristics.

Some stability fixes will result in a less realistic representation of the area of interest. You should consider if the benefit of removing instability exceeds costs of losing local detail.

You need to record all the fixes in the project report. You should regularly run the model with both low and high magnitude events. The high flows you use during development should be the maximum flow the model needs to accommodate. This allows you to address instabilities during the build process. The application of high flows will only be possible once floodplains are added in point 4.

Stability reporting is different for each model software platform. You need to be familiar with the measures of your chosen software. All models can produce flow and level times series and you can often see instability in these plots. As a minimum, you should check the graphs and report your findings because an unrealistic spike in peak water levels can affect flood mapping outputs.

You should run models for all events and scenarios that are requested within your project scope. The outputs you need to provide with your model will be different depending on the project. Your scenarios may form the basis of a more in-depth options appraisal project.

For NFM, your scenarios may need some more background analysis to determine the impacts on modelled flows. Hydraulic models can produce a large range of outputs, although many are not generated as default models. Check project needs before you carry out final model simulations.

This is particularly important for models where runs can take multiple days to complete. Project reporting is an essential part of hydraulic modelling projects.

A comprehensive report can:. As a minimum, you should include a:. Model passport or summary reporting is often not completed before hydraulic model technical approval is given. This should not result in the model being considered unsuitable for further use but may prompt a request for more information. Your summary report should include details of your hydrological analysis even though this is not mentioned in the MTRM.

You still need to justify any decisions you make about new modelling or model updates. Your model findings should also be reported clearly. The MUR provides reviewers and end users with the information needed to understand your model.

It also allows them to adopt and utilise the outputs of your model. You can add an MUR as an appendix to your summary report. It should include the following sections as a minimum:. However, you may not be able to provide any conclusions or recommendations until you have completed your modelling and post-processing of flood extents are approved.

It may be more appropriate to cover these in the model passport or summary report only. This will also prevent unnecessary repetition in your report. You can find a list of minimum modelling project outputs in the Represent buildings and infrastructure receptor part of this guidance. You should include a master document index MDI as part of your report. Your MDI should outline deliverables in your model.

You should review the scope of your project and MDI if you have included one once the project is completed. This will allow you to check that all deliverables are provided. You may want to include a record of superseded development versions if you have used a number of iterations.

This shows that you have tried to address stability problems. Your model versioning should allow a user who is familiar with the relevant modelling software to establish the final model version. It will also help them work out any associated scenarios without the need to examine your report in detail.

What is the most basic way to model a steady state flow to a forcemain, when the forcemain is basically the only component in the model? Is SewerCAD capable of locating air release valve? Thanks for the positive feedback about our products.

This article may be a good starting point for learning the software:. Regarding "modeling a steady state flow" - typically you would determine and enter sanitary loading information at the points where loads enter the system, then the program will solve the hydraulics around that. For a force main system, you may be loading this into an upstream gravity network, or you could lump them into a wetwell at the start of the model.

The program would determine the flow and HGL in the forcemain based on the pump characteristics that you enter, the upstream and downstream boundary conditions usually the upstream wetwell elevation and downstream outfall or gravity network elevation and system head characteristics.

You can set up a profile covering the force main in question and see if the hydraulic grade like falls below the pipe physical elevation at any point, which may be candidate locations for air valves.

This article explains how air valves can work in SewerCAD:.
