Subject: Indicators of hydrological alterations (IHA) Posted: 11/18/2022 Viewed: 604 times
I have some trouble with making this function work and I call for assistance. I know very well the IHA-concept, but I have trouble generating, or finding results, from an IHA calculation.
I have observed daily streamflow data from 6 years at 4 locations (gauges). In the Indicators of Hydrological Alterations menu (first tab - Analysis years), I select Compare Two Time periods. I split the 6 years period into two parts, and run the model. In the Results menu I select Hydrologic Alteration, and e.g. IHA Parameter 37 Mean Annual Flow. I am then prompted "No results available here", which is a bit surprising to me, as I would expected to see the changes in mean annual flow between to two periods selected for each of the gauging stations (and also for other nodes with streamflow results).
Any hints on what I could have done wrong? Thank you!
