You must collect the necessary data and translate it to model loading data regularly to account for changes to the network conditions. In addition, you may not know the actual location of the service meter. Help Center Find new research papers in: Estimation of Demands Using Land Use and Population Data Automated techniques also can assist in the estimation of demands using land use and population density data.

Point Demand Assignment A point demand assignment technique is used to assign a demand directly to a demand node. 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 can use these data sources to assign current demands; the difference between the two being the data that is contained within the source. This technique is unnecessary if all demands are accounted for using one of the other allocation strategies.

The total flow is then equally divided among the demand nodes within each of the meter route polygons.

Productivity Corner: Using Bentley WaterGEMS with GIS Data for Water Demand Allocation

To realize the full potential of the model as a master planning and decision support tool, you must accurately allocate demands while anticipating future demands. Log In Bbentley Up.

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. The known flow bemtley the lump-sum area generally is divided among the service polygons within the area using one of two techniques — equal distribution or proportional kanual Entire site Article Author Event News. Each service polygon has an associated demand node, and the flow that is calculated for each service polygon is assigned to this demand node.

The equal flow distribution option simply divides the known flow evenly between the demand nodes. If the data relates to projected values, you can use it for demand projections.

You may need to translate the data contained within the source — such as population, land area, etc. Enter the email address you signed up with and we’ll email you a reset link. These are some keyword suggestions for the term “Watercad”.

An example of meter assignment. Please send any technical comments or questions to our webmaster. Whether in automatic or manual mode, benley intelligent tools can bwntley you perfect your images. The lump-sum area is a polygon for which the total lump-sum water use of all of the service areas wahergems their demand nodes within it is known metered but the distribution of the total water use among the individual nodes is not.

Service polygons define the service area for each of the demand nodes figure 2. Skip to main content. You can determine a projected demand for each of the service areas and assign the demand nodes associated with each service polygon. AspenONE Engineering suite v8. The following are descriptions of the types of allocation strategies that you can apply using LoadBuilder. 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.

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. 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.

All exclusively from Cadalyst! This conversion entails translating the data contained within your data source to flow, which you then can apply using LoadBuilder. When using the nearest pipe meter assignment strategy, the demands at a meter are assigned to the nearest pipe. When simulating these dynamics in watsrgems water distribution model, an accurate representation of system demands is as watergwms as a precise model of the physical components of the model. Sometimes you must use the flow distribution technique to assign unaccounted-for water to nodes and when any method that uses customer metering data as opposed to system metering data is implemented.

Actify SpinFire Professional v8.

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. Follow Lynn on Twitter. Due to the difficulties associated with manually loading the model, you can use automated techniques developed to assist with bntley task.

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.

Deep Excavation A Practical Manual. 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.

Discover the exceptional performance of DxO Optics Pro. 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. In figure 3, the total demand in meter route A may be 55 gpm 3. Meter assignment is the simplest technique in terms of required data because you don’t need to apply service polygons figure 1.

Remember me on this computer. The lump-sum area in this case is a polygon feature class that represents meter route areas. 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.
