If the data relates to projected values, you can use it for demand projections. 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 can use various data types with this technique, including future land use, projected population or demand density in polygon form with the polygons based upon traffic analysis zones, census tracts, planning districts or other classifications. Follow Lynn on Twitter.

Many of these data types do not include demand information, so further data conversion is required to translate the information contained in the future condition polygons into projected demand values. You must collect the necessary data and translate it to model loading data regularly to account for changes to the network conditions. The equal flow distribution option simply divides the known flow evenly between the demand nodes.

An example of meter assignment. You can base the water-use data for these lump-sum areas on system meter data from pump stations, treatment plants or flow control valves, meter routes, pressure zones and TAZ traffic analysis zones. Each service polygon has an associated demand node, and the flow that is calculated for each service polygon is assigned to this demand node.

All exclusively from Cadalyst! Distribution This strategy involves distributing lump-sum area water-use data among a number of service polygons service areas and, by extension, their associated demand nodes. The lump-sum area is a polygon for which the total lump-sum water use of all bebtley 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.


Due to the difficulties associated with manually loading the model, you can use automated techniques developed to assist with this task. 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.

These techniques are similar to the flow distribution allocation methods, except that the type of base feature class that is used to intersect with the service feature class may contain information other than flow; for example, land use or population.

Allocation Allocation uses the spatial analysis capabilities of GIS to assign geocoded possessing coordinate data bentpey on physical location, such as an x,y coordinate customer meters to the nearest demand node or pipe.

Water cad v8i user’s guide. Enter the email address you signed up with and we’ll email you a reset link. Service polygons define the service area for each of the demand nodes.

This technique is unnecessary if all demands are accounted for using one of the other allocation strategies. Infonet only watrgems import xml files from Wincan V8. Point Demand Assignment A point demand assignment technique is used to assign a demand directly to a demand node. Deep Excavation A Practical Manual.

The spatial analysis capabilities of GIS make these applications a logical tool for the automation of the demand allocation process. The total flow is then equally divided among the demand nodes within each of the meter route polygons. 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: Discover the exceptional performance of DxO Optics Pro.

The demands associated with the meters within each of the service area polygons is assigned to the respective demand node points. This strategy requires the definition of lump-sum area or population polygons in the GIS, service polygons in the model and their related demand nodes.


Check out our Forum Guide for the instructions all forum members agree to abide. Depending on how the feature classes intersect, service areas may contain multiple demand types land uses that are added and applied to the demand node for that service polygon.

You can determine a projected demand for each of the service areas and assign the demand nodes associated with each service polygon. Note that you can use these data sources to assign current demands; the difference between the two being the data that is contained within the source. Please send any technical comments or questions to our webmaster. After an appropriate conversion method is in place, the service feature class containing the service areas and demand nodes is overlaid with the future condition polygon feature class.

Estimation of Demands Using Land Use and Population Data Automated techniques also can assist in the estimation of demands using land use and population bentleg data. AspenONE Engineering suite v8.

Write the CSS code manually or let the style sheet editor do it for you! Do you use social media — such as Facebook or Twitter updates, YouTube videos, or discussion forums — for work-related purposes?

There is one flow rate per polygon, and you cannot overlap open space between the polygons. Remember me on this computer. In addition, you may not know the actual location of the service meter.

This conversion entails translating the data contained within your data source watergemw flow, which you then can apply using LoadBuilder. The consumption of water is waterrgems driving force behind the hydraulic dynamics occurring in water distribution systems. 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.
