annotate flys-backend/src/main/java/de/intevation/flys/model/River.java @ 4241:49cb65d5932d

Improved the historical discharge calculation. The calculation now creates new HistoricalWQKms (new subclass of WQKms). Those WQKms are used to create new facets from (new) type 'HistoricalDischargeCurveFacet'. The chart generator is improved to support those facets.
