Hello WEAP users.
I have some problems with my study area.
I got streamflow data (from 1978 - 2010) at two stream gauge stations (one in the middle of catchment area and another one in the downstream of the catchment).
In the catchment, We have four reservoirs, but construction time of these reserervoirs is different: in 1992, 1996, 2003, 2004.
I would like to calibrate the WEAP model for my catchment, whether I can streamflow data from 1978 -2010 to calibrate the model or I should only use data after 2004, when these reservoirs already completed.
Can you give me some suggestions for my problem.
Thank in advance.

You can build your model with your current accounts year at 1978 and have the "last year of scenarios" as 2010, if you want to use all your data.
The key here is to build eachof your reservoirs and uncheck "active in current accounts." This will tell WEAP that each reservoir is built sometime after current accounts year (1978). Then, when you go into each reservoir, you can fill ou tab for "start up year." Remember, this information must be filled out in a scenario. For a model of the past, your "reference" scenario can simulate what actually happened in infrastructure, climate, etc., between the years 1978 and 2010 (or a shorter period if you decide to do that).

Thank you so much Stephanie. It's very useful for me.

I still have a question more, I already input data for four reservoirs. If I uncheck “active in current account” and setup startup year of the four reservoirs is1994, 2004, 2006 and 2010 respectively. The data of the reservoir that already input before seems to disappear. Are there any tips to help me use the data that I already input before? Or I have to input again.
