Because meter route A has 11 nodes, the demand at each node would be 5 gpm 0. 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: 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.

The consumption of water is the driving force behind the hydraulic dynamics occurring in water distribution systems. Automated construction of the service polygons may not produce the desired results, so you may need bentlsy adjust the polygon boundaries manually, especially at the edges of the drawing.

If the data relates to projected values, you can use it for demand projections. Many waatergems these data types do not include demand information, so further data conversion is required to translate the information contained in manaul future condition polygons into projected demand values.

An example of meter assignment. 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. Infonet only can import xml files from Wincan V8.


In a scaled drawing, pipe Download: Assigning metered demands to pipes also is a point-to-point assignment technique, because you still must assign demands to node elements, but an additional step is involved.

Note that you can use these data manula to assign current demands; the difference between the two being the data that is contained within the source. Assigning metered demands to nodes is a point-to-point demand allocation technique, meaning that known point demands customer meters are assigned to network demand points demand nodes.

Piping routes are not considered, so the nearest demand isn’t necessarily the location from which the meter actually receives its flow. You can use this type of demand estimation in the projection of future demands; in this case, the demand allocation relies on a polygon feature class that contains data regarding expected future conditions. Meter assignment is the simplest technique in terms of required data because you don’t need to apply service polygons figure 1.

Whether in automatic or manual mode, numerous intelligent tools can help you perfect your images. Point Demand Assignment A point demand assignment technique is used to assign a demand directly to a demand node. You may need to translate the data contained within the source — such as population, land area, etc. Help Center Find new research papers in: The lump-sum area for which a flow is known must be a GIS polygon.

Due to the difficulties associated with manually loading the model, qatergems can use automated techniques developed to assist with this task. Estimation of Demands Using Land Use and Population Data Automated techniques also can wattergems in the estimation of demands using land use and population density data. Service polygons define the service area for each of the demand nodes. The total flow is then equally divided among msnual demand nodes within each of the meter route polygons.


All exclusively from Cadalyst! Meter aggregation is a polygon-to-point allocation technique because the service areas are contained in a GIS polygon feature class, and the demand nodes are contained in a point feature class.

You must collect the necessary data and translate it to model loading data regularly to account for changes to the network conditions. Check out our Forum Guide for the instructions all forum wategems agree to abide.

Meter assignment can prove less accurate than the more complex allocation strategies because the nearest node is determined by straight-line proximity between the demand node and the consumption meter.

Please send any technical comments or questions to our webmaster.

It is easy because of the many awesome features such as auto complete, code inspector. This conversion entails translating the data contained within your data source to flow, which you then can apply using LoadBuilder.
