Adding reservoir release data

[Veronica Koess]

Hi everyone,

my watershed comprises two reserviors that i want to include in my SWAT+ model. The objects are already in the model as lake polygons but know, I want to edit the related res_rel.dtl decision tables. The release should be based on observed dam outflow. Therefore I have edited e.g. the pt0040 recall file to timeseries for the reservoir outflow channel cha0009.

Now, i am still struggling to edit the res_rel.dtl in the Editor in the right way. Could you assist me with the correct parameter? Please see the table that I have edited to my best knowledge based on the parameter options explained in the documentation https://swatplus.gitbook.io/io-docs/introduction-1/decision-tables/lum.dtl. I am unsure about setting the conditions that i actually want to avoid at all (as i am using the observed outflow data) ans also with the action type. I would preferably like to put an parameter like "release" together with obj res… I have now set flow_control and left the obj blank as there is no object type listed.

name conds alts acts
res1_release 1 1 1 

var obj obj_num lim_var lim_op lim_const alt1
vol  res             0      pvol            *               1      >

act_typ obj obj_num name option const const2 fp outcome
flow_control res 0 outflow_1 meas        -         - pt0040.csv y

I would appreciate any help on this. 

Best regards

Veronica

Just a quick update on this, I have updated the decision table to:

name                   conds      alts      acts

res1_release               1         1         1

var                      obj   obj_num           lim_var            lim_op     lim_const      alt

vol                      res         0              null                 -             0        >

act_typ                  obj   obj_num              name            option         const        const2     fp  outcome

release                  res         0         outflow_1              meas             -             -      1        y

I have added the recall timeseries files for the daily values of the pointsources, of the outflow rivers.

However, opening the Toolbox afterwards is breaking, so I assume there is an error in the model because of changing these reservoir parameters. Is anyone having an idea, what might happen, why the problems occur or how i could find the error?`

Best,

Veronica
