Steve Markstrom: Hi, this is Steve Markstrom.

In this presentation I am going to go through
what you need to know to get PRMS installed

and up and running very quickly.

Our quickstart presentation.

The first thing you need to do is go to our
website and download the executable GUI and

example problems, and that's from this link
right here.

The most current version is always going to
be at the top here and you can see some of

the previous versions down there if you needed
those as well.

The next thing you probably want to download
is the PRMS source code.

The version of the source code that was compiled
to make this executable.

That comes in very handy if you need to archive
your model or rebuild later.

The third thing that I would recommend is
to go ahead and download a copy of the PRMS

user's manual.

That's this link at the top.

There here are certain tables on the PRMS
user's manual that list the parameters, variables,

dimensions in the appendix.

As we come up with new versions of PRMS, we
update those tables so I recommend downloading

those tables and their updates to the PRMS
user's manual.

Here is the url for our web page, the PRMS
web page.

I'm going to do a live demo.

The first I'll do is go to the PRMS web page.

[types on a keyboard]

OK, and click on that, save the file.

OK, that's it.

It's downloaded.

I can go to my downloads, there it is.

Cut that.

Paste it here.

Unzip it.

OK, there it is.

This is the installation.

What I'm going to do is go into one of the
projects and here is the ACF.

This is the demo dataset that comes with the
model.

If I double click on this right here, the
GUI bat, you can see it starting up.

There it is.

PRMS is now running.

Here is the model runner and I click the start
button, and there is the model running with

the GUI.

That wasn't even close to taking me 5 minutes
to do.

That's installing and running PRMS.

I think what I'll do now, is just go through
that example directory and show you where

some of the stuff is.

In some of the subsequent talks, you are going
to hear people talk about the control file,

so if you go into this folder and look at
this file right here, this is the control

file in the control directory.

The control file is an ASCII file, and you
can see that there are various settings that

PRMS uses when it runs.

The content of this file is described in the
PRMS user's manual.

Likewise, if you go to the input folder, here's
the data file.

This is a text file as well.

I use notepad ++, but you can use your favorite
text editor.

Here's the data file, this has all of the
timestamps.

You can see them, year, month day, hour, minutes,
seconds and then data values.

You can see we've got a lot of data values
in there.

OK, that's the data file.

The other file you need to know about is the
parameter file.

That's also in the input directory.

Here's the parameter file.

Dimensions are at the top and then the actual
parameter values down below again.

Text file, you can look at this with your
favorite text editor.

If we go to the output folder, here is the
output that was just created with this model,

the run I just made.

You can see this is an annual water balance
summary.

That's one option.

Here's a statvar file, basically a time series
output of different selected variables.

Again, all these files are described in the
PRMS user's manual.

That's a quick overview of how to use PRMS
and that concludes this presentation.
