Hello, dear community
I have a flow time series (please see picture), I want to extract only data from specific dates (yellow fill in the picture) and stored it in a vector or array (Is It possible in a time series?) and work with those extracted values. How can I proceed? Thanks in advance for your support.
Best regards
Raúl
Raul,
I have a couple of follow up questions before I can propose something. How does the user select the dates? Do they enter the dates in a table?
what format do you need the results in? Can the values be entered into a vector result that has a pre-defined number of rows or does it need to go into a time series?
Can you explain further what the application is so I can also consider other ideas?
Thanks,
Jason
Hello Jason, thanks for your reply.
How does the user select the dates? Do they enter the dates in a table?
I have this in mind, as you can see, the "EastChannel" column has negative values, the idea is to extract only the positive values with their corresponding dates and couple them (using the date as an index) with the "Simulated flow" column values.
what format do you need the results in? Can the values be entered into a vector result that has a pre-defined number of rows or does it need to go into a time series?
The input is a time series, the output could be a vector or another time series (I don't know if this is possible). The idea is to use the "Simulated flow" with the "EastChannel" flow (registered values) because I want to calibrate this "EastChannel" flow with few records and use it with certain goodness of fit criteria (RMSE, correlation, bias, etc).
This is a case of calibration of small basins with non-continuous records by using a watershed model (e.g. GR4J in Goldsim). Please if you require more details please let me know.
Best regards,
Raúl
Raul,
I built a simple model that does what I think you need. Please download it from this sharefile location:
https://goldsim.sharefile.com/d-s76a719ee2a2247b8bfb92efe7ca77505
Here is a screen capture of the model:
The key is to define the time series as Discrete Change data type.
For more information about how to do this, please refer to our Help documentation: Generating Discrete Changes Using Time Series Elements (goldsim.com)
