Hi! Thank You so much for sharing these Hec-ResSim tutorials. You've really helped me to understand the very basics of Hec-ResSim.
I've managed to model and simulate a system that consists of one reservoir, two regulating weirs, and three regular Ogee-shaped weirs. One of the regulating weirs serves as a supplier for the reservoir, besides its main function for irrigation. The reservoir has a power plant with some certain operational constraints.
The release rules for this system were actually the results of my optimization model outside Hec-ResSim. For validation, I wanted to see if these release rules would result in different parameters in Hec-ResSim, and turned out they were pretty much the same.
Thanks for the feedback and good job on developing a model with that many different features.
That is a clever way to do it. Really appreciate you taking the time to make this video!
Hi! thanks for sharing! I'm working on a model and I need to connect a diversion from a reservoir to another reservoir in a parallel stream. So far the only way I've been able to do it is to add a "dummy" local flow to the inflow junction of the receiving reservoir. It is kind of working but I think there's a more elegant way of doing it. So please let me know what you think.
I believe you can connect a diverted outlet from one reservoir to the inflow junction of the receiving reservoir. This should allow you to write rules pertaining to the diverted outlet to move water to the receiving reservoir.
I may have to make a video to test and show this.
@@hecressim that’s a good point, since I’ve just tried my model with the “flow-thru” operation set you recommend, so I don’t have any rule in my model so far. I’ll try adding some rules and will let you know. Again, thanks a lot for sharing knowledge.
Hi! I tried adding a rule to send water to the parallel junction thru a diverted outlet and it didn't work. Still the only way it's working is with the "dummy" local flow. Did you have any breakthrough?
I need to do a video to show this, but I have a diverted outlet (found in the reservoir network module) connected from a reservoir to a junction above the reservoir, and it appears to work. I am not sure if I can connect to a reservoir junction or to the reservoir itself (it seemed to be giving me a problem with that). However, you can put in a dummy junction just above the upstream reservoir junction and connect to that if there is a problem with connecting to the upstream reservoir junction or the reservoir itself.
Very informative video!! Btw, can u show the DSS file data? how you arrange the data in DSSVue . thanks!
I should be able to post that in the next few days. I will let you know when I have it on the site.
Video showing how to develop HEC-DSSVue file has been uploaded.

Thanks again for posting this video. I'm giving this approach a shot, but ran into an issue. It seems like my model is recognizing only the maximum flow for the water supply diversion that I specified under the physical properties (I put in 100 cfs, somewhat arbitrarily). The model is not picking up the timeseries flow values from my dss file (varies, but generally around 40 cfs). Does this happen with your model too, by any chance? (I only think this might be worth checking because you had set both the max flow and the dss time series values to 50 cfs.) Trying to sort through this on my own, but figured I would check just in case. Maybe it is the structure of my DSS file causing the issue? I also looked into using the "function of date" option for setting the rule - but found it interesting that this can only accommodate month and day, not year, so that option will not work for this application, since the flow varies from year to year.
I think I resolved this. I had a rule conflict! My reservoir was operating within the flood control zone, and maybe that was why the model was using the maximum release rather than the specified time series for the water supply. Once I adjusted the flood zone, the time series for water supply worked great. Thanks again!
@@davidrailsback4874 Glad that worked for you. The specified release rule should work even when you are in the flood zone assuming that you have the rule applied in the flood zone. It should, however, use the full capacity of the outlet if you reach the top of the flood zone.
