We have an application that we develop but only work in metric unit from WinRiver ASCII output. Look at the attach document to how the software reformat and convert the data.

Hello,
I am using velocity data from a broadband ADCP to quantify flow fields
and velocity distributions in a river. I am looking for resources that
will enable me to more easily produce contour plots of equal velocity
lines. Transferring data from WinRiver and WinADCP still requires a lot
of data manipulation before producing XYZ formatted data needed for
contour plotting. And doing this for many transects can be labor
intensive. Is anyone on the list also doing this type of work and
willing to provide some insight on their methods?
Thanks,

Our procedure for doing what you describe goes something this:
1. Process the binary data files in WinRiver with appropriate settings
to produce an ASCII-Out files
2. Parse the ASCII-Out files with Perl scripts that:
(a) Transform (lat,lon) to plane coordinates (UTM, State Plane, or local
oblique Mercator)
(b) Extract the bottom track displacements as alternative horizontal
positioning for each ensemble
(c) Output the water track ensembles in a structured 2D "IJ-ordered"
data set with the variables of interest (Evel, Nvel, UpVel, ErrVel,
dB[1-4], Corr[1-4], ...), ensuring that data below the bottom is marked
as such. The ADCP transect files already have an inherent 2D structure
where I=#of bins and J=# of ensembles. If your contouring software can
handle blanking of regions based on input values or based on an
auxiliary field of data (i.e. the mark bad below bottom field), then no
additional gridding or triangulation is required. Of course, your track
has to be reasonably linear for this to be physically meaningful.
(d) Output the bottom track readings as a 1D "I-ordered " data set so
that you have a bottom boundary that corresponds to your water track
data
3. Import the water track structured data sets into your software and
contour based on cell average values or nodes. We use a commercial
fluid dynamics visualization package for this (E-mail if you want
specifics) but the freely available 'grdcontour' and 'grdimage' tools
(part of the Generic Mapping Tools http://gmt.soest.hawaii.edu/) also do
a very good job with this.
4. Import the bottom track data set and plot as poly line or discrete
points to represent the bottom below the water track data.
E-mail if you would like to discuss further or get scripts to use as a
starting point. What I have is not very user-friendly, but it is
automated. Hope this helps.

Hello All,
This year we deployed a Nortek 2DNDP in the river Meuse (Holland, Europe).
This is a river of approximately 130 m wide and 5 m of depth. Before the
deployment we have measured the actual beam pattern of one of the
transducers. With a hydrophone the amplitude was measured in a range from
-90º to +90º. All was done in an anechoic basin at the TNO FEL facilities
(The Hague). In case problems will occur with side lobe interference we will
be able to verify this with the data. If anyone has performed a similar
study, please let us know so we can share knowledge. Furthermore, if anyone
is interested in the data, the data and the report are available, though the
report is written in Dutch.
With regards from Holland,

We have a guy here in our office who is developing a program that does
real time bathymetry/flow mapping (flow not completely implemented yet). I
have personally used the program and am pretty impressed with it. Please
let me know if you are interested. I would very much like to see I there
is some way I could get him some program development funding if enough

Hi James,
I have a keen interest in this type of software for hydrographic
surveying applications. I think I know of the package you are referring
to and I would encourage you to continue with the development and
eventually distribution.
