Subject: hello
)Who you are
researcher in the field of horticulture economics, currently working on
my PhD
)What part of the world you are from
Germany, but working about horticulture in the republic of yemen
)Why you are interested in salinity-l
the region under research is highly arid (approx. 50mm a year). so all
production depends on irrigation. in former times this was mostly
achieved through flood irrigation when the wadis brought runoff from the
mountains twice a year, but with modern well and pumping equipment
farmers now widely utilize groundwater at an unsustainable rate.
"modern" comveyance and application methods like drip or bubbler
irrigation are very rare and there is the fear that they might result in
salinity problems. Thats why I am here.
)What your experience with salinity problems are
)Your knowledge on salinization / sodification
little
)Your specific questions or topics that you would like to see discussed
any ideas regarding irrigation under extremely arid conditions.

Subject: salt leaching
Sorry for cross posting.
Dear members:
I am trying to find models that will allow multi-year evaluation of salt
leaching under irrigated agriculture. We are trying to locate models
whose output allows quantification of vertical salt transport and
loading to groundwater given a soil salinity profile, irrigation
frequency and water depth, and relevant crop water use parameters. I
have used CHEMFLO and VS2DT before and am familiar with SWMS_2D which is
relatively similar to VS2DT. Both VS2DT and SWMS_2D include plant water
uptake. Has anyone used these models to simulate multi-year salt
transport to groundwater under irrigation? Do you suggest other models?
Thanks.

Subject: Effect of irrigation on ground water
Dear Members,
I have just joined this discussion group, and would like to ask for
opinions and any other information regarding the effect of irrigation on
ground water.
By the effect of irrigation, I do not mean withdrawl of ground water and
hence depression in ground water level. Instead the context I am looking
at is regarding the effect of "flushing water" (in which
you apply to the ground in order to flush the salts downwards towards the
water table) on ground water levels (ground water levels rising as a result
and thus causing salination, by their salt content).
If you can direct me to any appropriate literature I would be most grateful
for your help.
Yours sincerely,

Thank you for responding to my enquiry on salt transport models. Below
are the answers I have rec'd so far. CHEMFLO is obtained from USEPA
(EPA/600/8-89/076, August 1989), VS2DT from USGS (Water Resources
Investigations Report 83-4099 and 90-4025), SWMS_2D from US Salinity

Answers -------------------------------------------
Said Amali,
There's a SWMS_3D model to simulate water and solute flow in 3
dimension.
I haven't yet had a good look at it, but thought you might be
interested.
If you want the model, you can contact:
wrussell@ussl.ars.usda.gov
Everything's free with the program: source code, samples, documentation
even postage - true spirit of the Internet!

Said,
I forwarded your message to Dr. Mike Shannon (U.S. Salinity Lab,
Riverside, CA), Dr. Jim Rhoades (U.S. Salinity Lab), and Dr. Jim
Ayars (USDA ARS, Fresno, CA). I think one or more of them might be able
to answer your questions.

Said: Check with John Letey (916-787-5105) and Don Suarez at the U.S.
Salinity Lab. They both have models which can be used for multiyear
analyses. Suarez's has the full inorganic chemistry (calcite, gypsum,
and
cation exchange equilibria). John's doesn't have inorganic chemistry
which
is a limitation when calculating salt loading to underground acquifers
irrigated soils that are calcareous and gypsiferous (westside, San
Joaquin
Valley).
Dear Said:
I have a published model which could be used for the problem you
describe. It is called Opus, and in simulates the soil rootzone
profile and crop growth, water use, runoff, and chemical transport.
To simulate salt loading to groundwater, you will be in the long term
simply subtracting the plant ET and soil Evap from whatever
concentration of salt is in the irrigation water. Opus does not
explicitly include the specification of a chemical composition of
irrigated water, but you could input the right amount of chemical at
the same time as the specified irrigations, and the model would do
the rest. You can use a randomly generated weather pattern (included
in the model) if you are applying the model in the continental US, or
the model will run on measured data, or on smoothed records of mean
monthly values of temperature and radiation. For your application
you should have pretty good values for the soil hydraulic properties.
Opus runs under DOS, and the user manual and
documentation manual are available from me if you are interested.

Dear Said
There is LEACHM, a public domain 1-d water and solute (Pesitcides,
salts, Nitrogen) transport model. If you do need a copy of the source
code please let me know I can send it to you via email. Good luck

I am not familiar with the models you are considering. However one
important consideration, in my opinion, is whether they allow using
good crop models for the crop you are interested in. The 2DSOIL and
RZWQM models are designed to have various crop models attached to
them. I am most familiar with 2DSOIL in this respect.

Dear Said:
Opus has been tested by several others in the movement of both
pesticides and the movement and cycling of nutrients. It has not
been "tested" specifically as a salt transport model, but the
transport is the same as for a non-degrading, non-absorbed chemical
(pesticide).
The documentation is available free while supplies last, to those
who have an appropriate application for the model.

Two years ago, I used the SWMS_2D to simulate multi-layer acid mine
leaching to groundwater. I know the CHEMFLO model but I'd not really
used it. I think the SWMS_2D model is convenient for the work you to do.

LEACHM can simulate sorbing and non sorbing solutes, it also can
simulate pesticides (degradation, sorption, plant uptake ...) So
obviously it can simulate salt.
I suppose

do. )I know LEACHM has been around for a while, but has it been tested

The models (leachm or vs2dt or any other model) do not diffirenciate
between rainfall and irrigation because both of them are water input
into the simulated system. Thus, leachm and Vs2dt(I worked with it too
and I modified it during my Ph.D. work to handel surface water body
adjacent to a soil surface) can handel both water input from rain and
irrigation you just have to input it into the input file correctly.

) I forget the name), University of Maryland, or Massachusets or

Leachm was developed by Hutson J.L. and R.J. Wagenet in Cornell

Dear Members,
I joined the discussion list in 1996 and have been enjoying the discussions
since. We are working in a project that deals with the determination of
revegetation potential for salt sensitive native riparian vegetation in New
Mexico. Soil salinity is a major component in the potential analysis.
I would like to request your assistance in two topics:
- Are there any good publications/is there any information on salt
sensitivity of natural vegetation, more particularly trees?
- Is reflection of plants under salt stress different from salts under
water stress and which would be the best frequencies/bands/combinations to
use in remote sensing analysis of salinity??
I would be very happy with and grateful for any information/help I could
receive in these matters,
Sincerely,
Jelle Beekma

Dear Jelle,
I work with the Dept. of Nat Res & Env in Victoria, Australia.
Salinity is one of our concerns here. I work with a little bit with
trees, of course mostly Australian Spp (eucalypt, acacia, melaleuca
etc). We irrigate them with 10 dS/m water and they don't seem to mind.
Also I have been looking at a small tree planting growing on a
shallow, initially fresh, watertable. After 20 years the trees (
E.grandis, camaldulensis) have concentrated the salt in the
watertable underneath to up to 25 dS/m concentrations.
A problem with describing the salt tolerance of trees is their
relatively large root system; if salt increases in one part, the tree
roots in other parts seem to become more active.
I will pass on the address of a more qualified (than me) Australian
expert on tree salt tolerance separately.
Re the stress expression of salinity, I have always been told that it
is similar to drought. So the best would be to look at seasons where
water is not (or least) limited and look at stress symptoms (be
carefull not to mistake insect attacks for drought; they caould have
similar signatures)

Subject: Who am I??
Dear Members,
I wish to introduce myself to the Salinity-l discussion group.
My name is Terence Batey and I currently reside in Shepparton,
Victoria, Australia.
I studied at La Trobe University (Bendigo Campus) and majored in
Environmental Science and Chemistry. I continued with Honours in
Chemistry and looked at the effects a eucalyptus distillery had on
surrounding soil (in particular soil chemistry). I studied soils
upon which burnt leaves were stored (alkaline soils - pH ) 10) and
why no natural regeneration was occuring at the distillery site which
had been abandoned for more than 50yrs.
My current field of work is hydrology and at the moment I am involved in a
project looking at farm scale evaporation basins for managing
salinity in irrigation areas. The project hopes to develop and find
support for use of small (2-3% of total farm size) evaporation basins
which store groundwater of varying salinity while utilising some of
this pumped groundwater for mixing with channel water for irrigation.
I am also looking at the effects of soil sodicity on infiltration
rates of winter rainfall.
Previous work I have been involved with looked at the salt and water
dynamics beneath young tree plantations in the Shepparton Irrigation
Region.
I am interested in Salinity-L because of its up to date supply of
current technology and what other people around the world are doing
in terms of research into aspects of soil salinity and sodification.
I am interested in hearing other peoples experiences with salinity
and in particular work with evaporation basins (surprise...surprise).
I look forward to reading other peoples information and contributing
to any discussion groups.
Cheers
Terry Batey

Subject: Modelling salinity of crops by ground water
Greetings to all members,
I am a fresh graduate, and have been with this current company for the last
two months. A while ago I posed a question to the group, regarding the
effect of irrigation on ground water level. Thanks for all the replies I
received.
However, now that I've kind of worked out what exactly happens, I'm trying
to model the whole effect: irrigation water reaching the ground water,
water table rising as a result, and finally the drainage process.
Can anyone who is familiar with this problem, and has been involved in
modelling this process, write me a short note as to how to incorporate
various parameters, such as drainage.
I'd be most grateful for any input. Thank you all,

Dear Mr. Kordestani,
as a starting point for general information on computer based modelling
of irrigation, try
http://fserv.wiz.uni-kassel.de/kww/irrisoft/irrisoft_i.html
more specifically have a look at
http://fserv.wiz.uni-kassel.de/kww/irrisoft/manage/bigsim.html from
where you can download (free of charge) a model that might fit your
needs as it seems to allow for drainage design as well (however, i have
not used that interface so far). salinity effects are also well
included!!!
could you provide the readers of this group with a short summary of the
responses you got so far?
kind regards, peter
