Structure of The Model
WAFLEX is set up as a network, where each cell is river reach, demand node or reservoir. Each cell contains a simple formula to add water flowing into it from adjacent cells, and to subtract any demand connected to that cell. The network is set up twice, in demand mode and in supply mode.
The inputs to WAFLEX are:
- river inflow time series - source area of where the model starts
- demand node time series, e.g. a settlement water supply
- reservoir rule curves and dimensions
- time series from gauges for calibration
The outputs of WAFLEX are:
- time series for specified points on the rivers - these can be calibrated against gauges
- time series of abstractions and shortages for each demand node
- time series of reservoir levels
Code can be readily added to generate the above outputs graphically.

Famous quotes containing the words structure and/or model:
“One theme links together these new proposals for family policy—the idea that the family is exceedingly durable. Changes in structure and function and individual roles are not to be confused with the collapse of the family. Families remain more important in the lives of children than other institutions. Family ties are stronger and more vital than many of us imagine in the perennial atmosphere of crisis surrounding the subject.”
—Joseph Featherstone (20th century)
“I’d like to be the first model who becomes a woman.”
—Lauren Hutton (b. 1944)
