Hydrograph truncation warnings


 Product(s):Bentley PondPack

Problem

User is receiving hydrograph truncation warnings. Why?

Solution

In PondPack a truncation warning simply means the hydrograph does not begin or end on zero flow. So if you have a base flow you will get a truncation warning. Another cause of truncation is rooted in the calculation increment. For example, if the increment is too short, the total time period will not cover the full extent of the hydrograph will not be calculated, therefore it will be truncated on the right side. On the other hand, if the computation increment is too large, the beginning of the hydrograph could be missed and, therefore, starts at a point later than the beginning of the hydrograph.
