Monthly Pattern demand model
A monthly-pattern demand node allows you to describe a demand as monthly values in megalitres. This is a simple representation supporting the needs of demand and supply analysis. The demand from nodes is accumulated in a bottom-up pass to the identified supply storage, from which water is released (if possible) at the appropriate time to meet the demand. You can configure the model by right-clicking
Demand Models and choosing
Monthly Pattern from the contextual menu (
Figure 1). Next, specify the monthly demands in ML.
Figure 1. Water User node (Monthly Pattern, Demand)
You can enter monthly demand values directly or load the data from a file. Table
1 shows the format of a comma-separated (.CSV) file for importing monthly demand data. For simulation over smaller time-steps, the monthly volume is evenly distributed across the time-steps for that month.
Refer to Return flows for configuring Return flows in the model.
Table 1. Water User node (Monthly Pattern, data file format)
Row | Column (comma-separated) | |
|---|---|---|
1 | 2 | |
1 | Month | Order per Month (ML) |
2 | month | order |
Where: month is the first three characters of the month name with a leading capital letter (eg "Jan")
order is the order in megalitres for the corresponding month.
