When simulating these dynamics in your water distribution model, an accurate representation of system demands is as critical as a precise model of the physical components of the model.įrom the pipe, the demand then is distributed to the nodes at the ends of the pipe by using a distribution strategy.
#Bentley watergems manual
This strategy primarily is a manual operation and is used to assign large generally industrial or commercial water users to the demand node that serves the consumer in question. You may need to translate the data contained within the source - such as population, land area, etc.

It is easy because of the many awesome features such as auto complete, code inspector. Discover the exceptional performance of DxO Optics Pro. Automated construction of the service polygons may not produce the desired results, so you may need to adjust the polygon boundaries manually, especially at the edges of the drawing. The known flow within the lump-sum area generally is divided among the service polygons within the area using one of two techniques - equal distribution or proportional distribution: This conversion entails translating the data contained within your data source to flow, which you then can apply using LoadBuilder.Īn example of meter assignment.

Whether in automatic or manual mode, numerous intelligent tools can help you perfect your images.
In most of civil engineering projects from Housing to hydraulic related projects hydrology is mostly involved in combination with fluid mechanics. Enter the email address you signed up with and we’ll email you a reset link. The greater the percentage of the lump-sum area or population that a service polygon contains, the greater the percentage of total flow assigned to that service polygon. Write the CSS code manually or let the style sheet editor do it for you! Due to the need for service polygons, the initial setup for this approach is more involved than the meter assignment strategy - the trade-off is greater control over the assignment of meters to demand nodes. Productivity Corner: Using Bentley WaterGEMS with GIS Data for Water Demand Allocation | Cadalyst Piping routes are not considered, so the nearest demand isn’t necessarily the location from which the meter actually receives its flow. Note that you manuap use these data sources to assign current demands the difference between the two being the data that is contained within the source.įollow Lynn on Twitter.
Meter assignment is the simplest technique in terms of required data because you don’t need to apply service polygons figure 1. In a scaled drawing, pipe Wtaergems The lump-sum area is a polygon for which the total lump-sum water use of all of the service areas and their demand nodes within it is known metered but the distribution of the total water use among the individual nodes is not.
