Re: MRN: tracer output

Hi david :) Ok, so 1800kg is the same amount I got before using integrate related keywords (using USE_ORIGINAL_VALUE in the discharge data, I think is better using this ON, since I know the amount I´m introducing, no? I know the exactly amount between each data step.. ok. But, it seems normal to you...

Re: Operations with hdf data

Thank you david! ok! my mistake..I wasnt thinking at all in the interpolation made in time series (althoght I have already used them for interpolating rain..) Clarified as well the max_span, I was confused cause I was seeing how the interpolated value was changing with a change in this keyword, but ...

Re: Operations with hdf data

Hello! I just found the answer to part of my problem!! :D The value of the cell doesnt fit because the hdf´s columns and rows are reversed.. ok, and I also had a problem with time series, that in the cells with rotation just near the ID change, the cells were taking an interpolated value. As in the ...

Re: MRN: tracer output

Thanks a lot David and Eduardo! :) Ok, so I set the keywords you told me, integrating them at an hourly time step. In the attached you can see, in blue the concentration in a simulation previous to using those keywords, and in red, with them (so the integrated mass). I don’t understand two points he...

Re: Operations with hdf data

Hello all! Not so easy as it looked.. :) After giving a value of -99 to all the cells falling out of the delineation, I opened the data file in excel so that I could calculate which cells were following each rotation and so. So now, I have a grid data file with different cell values corresponding to...

Re: Operations with hdf data

I thought I would need arcgis but I found an alternative way!! :D
just deleting the cells out of the catchment and then playing with the leyend maximum and minimum, i managed to visualize only the cells I need!!

Re: Operations with hdf data

I managed to do sth like this!! :) After converting the grid data or hdf file to shapefile, I opened it with arcgis and I clipped the information inside the delineation. Then simply, I could count the number of polygons of different values. I have one question here, and it is that, how mohid conside...

Re: MRN: tracer output

Hi all! With the intention of simulating an aport of nitrates to the river, I have created a time serie in which the time step of the aport is short and the flow is little (big concentration in consecuence). It is sth like: Hours flow nitrate <begintimeserie> 0 0 0 120.9 0 0 121 1.38e-4 50000000 121...

Re: MRN: tracer output

Hi! I´ve let the model more time to consider the discharge and I changed the node to prove this in other node (I think I had a problem with the node, sorry), and now its working with a discharge like (and without using USE_ORIGINAL_VALUES): hours flow nitrate <BeginTimeSerie> 0 0 0 120.9 0 0 121 15 ...

Re: MRN: tracer output

hello david, Discharges keyword in drainage network is in capital letters, yes. But it seems it´s not reading the discharge. It reads if constant value but something fails with time serie. Just in case, I post it here :) NAME : Station Name COORD_X : 0 COORD_Y : 0 SERIE_INITIAL_DATA : 2008 1 1 0 0 0...

Re: MRN: tracer output

Hello all! I wanted to simulate an aport of a solute to the river, and to do so I have created a time series with the columns of date, flow and concentration. After many proves I dont manage to do it so I think I´m missing something. I post here my files so that maybe you can see something. drainage...

Re: Water uptake by vegetation

Ok, I think I wrote about feddes and you thought I was speaking about feddes stress, sorry for the misunderstanding. So, just to let it clear, can you let me if I´m right? --The potential transpiration (Tp) is calculated by Tp=Etc*1-e^0.463Lai ,and this value is for the plant for a growing stage. Is...

Re: Water uptake by vegetation

Hello david, Thanks for the explanation. Ok, so whatever the roots form is, the potential transpiration will be the same in both methods obtained from root distribution option right? As it is calculated with (Tp=Etc*1-e^0.463Lai) formula. What I was asking about feddes is that to calculate effective...
