STREAM is a U.S. EPA product which uses HSPF model calculations to predict
pesticide concentrations in particular scenarios, as a function of pesticide
properties. It was a brilliant achievement but ahead of its time. It MAY be
at the ftp site earth1.epa.gov in the epa_ceam/dos subdirectory (you'll have
to explore). The model is documented in an EPA report by Donigian, et. al,
"Stream Transport of Agricultural runoff of Pesticides for Exposure assessment:
A Methodology" EPA Rept. No. EPA/600/3-86/0111a (and there may be a part b)

ICRISAT

CROP PRODUCTION SYSTEMS MODELLER
[Code no:IAC-04-Z]

The International Crops Research Institute for the Semi-Arid Tropics
(ICRISAT) is a nonprofit, autonomous, scientific research and training
institute with regional centers and teams in Asia and Africa. The Institute
is seeking a scientist to support the Institute's research in India and
Africa in cropping system simulation modelling. The Systems Modeller will
be located at the ICRISAT Asia Center, Patancheru (near Hyderabad), India.

With the support of the Australian Centre for International Agricultural
Research (ACIAR), ICRISAT is collaborating with the Agricultural Production
Systems Research Unit (APSRU) in Australia in a joint project on integrative
systems research. A central objective is a reliable simulator which will
aid RD&E on farmers' management of their crops and croplands, especially
regarding investment in soil fertility and in soil and water conservation,
in the face of highly uncertain seasonal rainfall and yields. The
collaboration brings together ICRISAT's experimental data bases for India
and Africa and APSIM, a cropping systems simulator developed in the
Australian semi-arid tropics and subtropics.

The Systems Modeller's primary responsibility is to expedite the effective
use of APSIM in ICRISAT's research. This will entail the testing of
existing component crop and soil models and the development of new modules
for APSIM. He/she will work with project teams in developing efficient
systems of data collection for models, in using the data to specify and test
models, and in using system simulation to enhance project research. An
important part of this task will be the development of self-reliance within
project teams in using APSIM.

Applicants should have a PhD degree or equivalent qualification in an
agricultural science, substantial experience in soils-oriented agronomic
research, and in using simulation models in such research. Applicants
should be proficient in FORTRAN. Proficiency in oral and written English is
necessary, and a command of French desirable. Experience in international
agricultural research and with semi-arid agriculture will be an advantage.

The appointment will be initially on a two year contractual basis with the
possibility of further contracts. An internationally competitive salary and
benefits package will be provided. ICRISAT is an equal opportunity employer,
and is especially interested in increasing the participation of women on its
staff. ICRISAT is responsive to the needs of dual career couples. A Fact
Sheet on employment possibilities for spouses is available on request.
ICRISAT has a flexible approach to international appointments and welcomes
enquiries from persons interested in working at ICRISAT while on secondment.
Applications, referring to the code number should reach the Chairperson of
the Search Committee, Dr C.Renard, ICRISAT Asia Center, Patancheru, Andhra
Pradesh 502 324, India [phone:+91(40)596161; fax:+91(40)241239] by 30
September 1995. The application should include a current curriculum vitae,
the names and addresses (including fax/telex/e-mail) of three referees, the
date of availability, and a statement on the special qualifications of the
candidate for this position.

Hello,
sorry to send this non subject related message to the list, however I feel it
is important enough and might be of interest for you. You might have heard of
an e-mail chain letter against nuclear tests which was circulating around.
Now, the originator decided it was a better idea to make up a http page
so that people could sign up there directly, without having thousends of
copys of the letter to be circulated. Below I include the letter from
the originator and the WWW-address of the http page.
Thanks for interest and sorry for cross-posting

Subject: The list is terminated

First of all, I have to deeply apologize everyone for my having started a
chain letter. Thank you very much for those of you who have pointed out the
troublesomeness about the chain letter. I have decided to stop collecting
signatures by using chain letter, (ofcourse I will collect the names already
signed on it) but then, I have to use the same method to stop it. So, please
forgive me of my asking you to send this letter to everyone who you have sent
the "Stop Nuclear Tests!" chain letter. I am sending this letter to everyone
who have sent me a letter concering this matter, so some of you might receive
more than one copies of this letter, but again, forgive me of this happening.

If you have sent a copy of the "Stop Nuclear Tests!" chain letter
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
to your friends, please send a copy of this letter to each of those
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
friends as soon as possible.

If you haven't sent a copy of it to anyone and still have the
copy in your hand, please send the list back to me. My e-mail address is
keshi@uticeaix1.icepp.s.u-tokyo.ac.jp

Don't forget to add your name on the list if you do think
the French government, or any other group should not execute
nuclear tests.

Right now, Shimizu Seishi and I are constructing a WWW Homepage
to continue this activity. From now on, We will gather signatures
via WWW, or simply accept signatures sent to us. We would also like to
show the list on WWW, but if you don't want your name to be
open to the public, please tell me so. We will keep your name
on the list that will be sent to Mr. Chirac, the president of
France, anyway.

The WWW homepage will have the follwing contents:
* The objective of this activity
* The list of signatures
* A page to introduce opinions about the Nuclear Tests
* A page to ask for technical advices to make this activity a better one
* Links to related pages

Hello everyone:
My name is Rabi Mohtar, a research associate at Penn State working on grazing s
ystem modelling. We have developed a computer model GRASIM that simulates the
grazing environment. It includes a grass, soil, water, nitrogen, grazing manag
ement components. GRASIM integrates information available in several existing
models namely: NLEAP (nitrogen model), Johnson and Thornley (grass model), Ritc
hie (evapotranspiration). We are continually updating the model and are workin
g on field testing and validation at this stage.

My question to the group is: does anyone has data or leads on data on the parti
oning of photosynthetic material between leaf and stem for cool season grasses.
Thank you in advance for any response.

Hello,

Was wondering if anyone could tell me how AGNPS 5.00 calulates an
EI value. In other words, how is the amount of rainfall
distributed over the length of the storm (I guess I'm looking for
a table of numbers that show % of rainfall fallen vs. % of storm time
which has passed) - in particular for a Type II storm. Any suggestions?
I calcualted some by hand based upon a USDA publication - Agr. handbook
#537 - and the values I came up with weren't quite the same.

thanks,

Michael

I am attempting to run detailed PRZM2 groundwater simulations of the
vineyard regions in France. Because I am interested in simulating
a "reasonable worst case" I am most interested in modeling the south central
region of France. I have not been able to uncover detailed soils nor
climatological data for the region of interest. I have relied on the weather
data and soils data outlined in Chapter 5, European Scenarios for Leaching
Models, M. Klein and H Knoche (authors) in the recently published FOCUS
Report on Leaching Models and EU registration.

Unfortunately I have found these data lacking, particularly with regard
to horizon specific soils characteristics. I have also investigated
obtaining soil characterization data from the GISCO Office in Luxembourg
with little success to date.

My inquiry then is several-fold.

1. Do detailed soil characterization data exist for Europe, and in this case
particularly south central France? If so, how and where can the data be
accesed?

2. Do detailed climatalogical data exists for specifc regions in Europe and
if so, where can those data be accessed.

We have not found any source for detailed soil characterization data
that is easily obtainable. There is a database/information system
called SEISMIC that contains only UK soils (412 soil series). Some
limited climate and crop info is also included. Available from the
Soil Survey and Land Research Centre, Cranfield University, UK.
A yearly fee is charged.

The National Climatic Data Center does have data for over 8000
stations globally. Historical data must be purchased from them
on mag tape only. Data less than a year old is available online
at:

http://www.ncdc.noaa.gov

or by ftp at:

ftp.ncdc.noaa.gov ; then cd /pub/data/globalsod

For PRZM-II Monte Carlo runs, the cost is very expensive (multiple sites
x ~30 years of weather/site).

You might try contacting CEMAGREF, which I guess could be thought of as the
French USDA/ARS (?). Anyway, I have the E-mail address of Veronique Guoy who
has done some water quality modelling in vineyards and has probably had the
same question. Her interest is in runoff (and by the way, I would like to

I am particularly interested in the way wheat data in collected for these

I believe there are short (~1 page) questionnaire the grower fills in at
harvest time.

If anyone could clarify the way these systems operate and provide examples of
the data collection questionnaires it would be most appreciated.

Could you please email directly to me. M.Lunney@dpi.qld.gov.au

I have a colleague who is looking for a pasture water-use model. Specifically,
he wants to be able to predict when the soil surface under a pasture is wet
(and hence likely to be dissolving fertiliser granules), and when not.

Does anyone know of any relevant models? There are many models for crops which
include soil evaporation as well as crop water use, but I know of none for
pastures.

Thanks for the response. With regard to runoff, we are presently
interested in the ground water issue to support some internal inquiries.
However, when we get around to writing the risk assessment for the
compound runoff will become important. Should you care to offer any
suggestions in this regard feel free to do so.

Dear Chris:
The real challenge is in estimating the grass/legume canopy under grazing. I h
ave used various water budget models that were developed for row crop including
Ritchie's and others and I was quite pleased. Beside from the fact the canopy
(Leaf Area Index) changes irrotically according to growth and animal intake,
I can not see any reason not to use the abundant water budget models already av
ailable.
There are several models that will predict grass canopy under grazing. If that
is of interest I can suggest some and I am sure many of the colleques on the n
et know of others.

The QLD DPI have a GRASs Production (GRASP) model which is run over the
entire state simulating pasture production. The model's usage has been
published in a number of articles although I'm not sure whether the code has
been documented (fortran). The water balance model in GRASP is based (I
think) on the WatBal model of Ken Rickert. This was
originally developed from a wheat water balance model. I think the same
water balance model may have appeared in a model called PROBE (an early
version of GRASP) of which I
think there may be some documentation. I'm sorry I can't be of more use, if
you have trouble finding literature on these models let me know and I will
see what I can do.

I am planning to develop an irrigation scheduling model to irrigate tree
plantations using waste water. My proposal is specific to saline drainage
waters and municipal and industrial effluent. This model will give users
the various options of scheduling irrigation, ranging from using simple
guidelines of using regional long-term pan evaporation data to complex
models of using complete local climatic data (i.e Penman-Monteith
equation).

Do you know any of such models I could use or start with?
