Learn how InfoWorks converts existing WATSYS network components into an InfoWorks network and InfoWorks network objects.
Some data is not imported at all, or is only partially imported. Some WATSYS objects are imported as more complex InfoWorks objects, and additional data will be required to completely define these InfoWorks objects.

Valve Characteristics **VC Data Group
Notes on import of Valve Characteristics:
- The WATSYS default valve curves are imported into the IWWS Valve Curves grid.
- If a user defined valve is defined in the WATSYS file, the user defined curve will be imported into the IWWS Valve Curves grid, if the coefficient values are K values.
- If L or CV values are used, a valve curve specific to the Valve in the Valve data group will be imported into the IWWS Valve Curves grid. The L or CV values are converted to K values using the specified valve diameter or a default diameter of 555mm. The IWWS Valve Curve ID for the valve will be based on the WATSYS valve Label.

Reservoir Records **RE
Notes on import of Reservoirs
- If the WATSYS Initial Depth is such that either of the IWWS maxima for depth or volume are exceeded, the reservoir is imported as a fixed head set to the Initial Depth.
- If the WATSYS Overflow Level is greater than the IWWS maximum depth the Top Water Level is set to the maximum depth.
- If the WATSYS Level / Cross-Sectional Area pairs are such that the reservoir depth or volume exceeds the IWWS limits, the top of the reservoir is removed proportionally until both depth and volume are within the IWWS limits.
- If the WATSYS Level / Cross-Sectional Area pairs are such that the reservoir depths are within the Top and Bottom water levels, IWWS extrapolates the Depth Volume curve between the top and bottom water levels.

- If WATSYS Reserve Storage > 0.0, IWWS Minimum Operating Level is set to the WATSYS Bottom Level.
- The IWWS Bottom Level is determined by calculating the point on the Level / Cross Sectional Area curve below the WATSYS Bottom Level which corresponds to the Reserve Storage.
- If there are no curve levels below the Bottom Level, or the curve does not extend far enough to meet the Reserve Storage volume, a cylindrical shape will be assumed before the first curve point.

Demand Records **DE
Notes on Demand Records:
- A demand category will be imported into the IWWS Demand Diagram for each Default Record in the WATSYS Demand Record group that is used at a node in the network.
- Default Records are converted to a sequence of time, flow factor pairs. If the WATSYS Area Size and all flow factors in the Area Label are positive, the demand records are imported directly as Node Demands. Any demand at a Head Point is ignored.
- The WATSYS Curve Sequence is determined from the Demand Record default record
- The WATSYS Demand Variation Curves that make up the profile are determined from the Curve Sequence
- Multiplying factors from the Demand Types group are applied.
- The resulting profile is imported into the Demand Diagram as a seven day profile starting from m the day specified during the import process on the
Select File Page. The WATSYS/WaterMax sequence will be truncated if it is greater than seven days or extended if it is less than seven days.
- A Demand Scaling object is created on import of a WATSYS/WaterMax model. The Demand Factor in the Demand Default Record is converted to a category scaling factor in the Demand Scaling.
- Daily Demand Factor Sequences group are imported as Daily Coefficients in the Demand Diagram. (Only the first seven values are used.)
- If either the WATSYS Area Size or any of the flow factors in the Area Label are negative, the node will be imported as an IWWS Transfer Node, provided it is not a Head Point or a Reservoir. The Transfer Node flow profile is constructed by summing all Demand Records for that node.
- Any negative demand at a Reservoir results in all demand at that node being cancelled.
