Integrated Decision Support Consumptive Use and Alluvial Water Accounting System
One Day Training Course
May 19, 2005 Colorado State University
The Integrated Decision Support Group at Colorado State
University will conduct a one day hands -on training
course on the use of the IDS Consumptive Use model (ID-
SCU) and the IDS Alluvial Water Accounting System model
(IDS AWAS). These models were developed as a part of the
South Platte Mapping and Analysis Program (SPMAP), a
collaborative effort between IDS and water users in the South
Platte Basin. The models are data driven and being used
around Colorado.
This training course will instruct users on how to create and
use templates to develop data sets; use diversion records
from HYDROBASE; and access weather data from HY-
DROBASE, COAGMET, and NCWCD. Features of the
IDSCU model that will be discussed include: 1) computing
a complete water budget, 2) using the model to compare CU
values computed with different ET methods (this will be used
to demonstrate how a user might develop calibrated Blaney-
Criddle crop coefficients), and 3) evaluating the application
efficiencies of wells by comparing depletions of groundwater
computed using a water budget with pumping records multi-
plied by a presumptive depletion factor.
The training course will include an introduction on how
to export depletion of groundwater information to the IDS
AWAS model or generate input files for the IDS AWAS
model. Participants will then be shown the major features of
the IDS AWAS model. The participants will be introduced
to a number of GIS tools that IDS has developed to calculate
the input parameters for the IDS AWAS model such as dis-
tance to river, distance to boundary, and transmissivity. The
training course will be conducted on Thursday May 19, 2005
at Colorado State University.
The cost of the registration is $200. Course registration will
be limited due to the availability of computers for hands -on
training.

Heermann Retires from USDA -ARS in May
Dr. Dale F. Heermann, Agricultural Engineer, (Water Management Research Unit) will retire on May 3, 2005 after 38 of
years with the USDA -ARS in Fort Collins, CO.
Celebrations include a reception on May 3 from 2:30 — 5:30 p.m. in the North and
South Platte Conference Room, Building D, Natural Resources Research Center,
2150 Centre Drive, Fort Collins and a dinner on June 10"` at the Fort Collins Senior
Center. For more information about either of these events, contact Harold Duke at
[e-mail].
Dale Heermann grew up in Scribner, NE and graduated from University of Nebraska
where he served an internship with the USDA -ARS. After a stint in the U.S. Air
Force, he completed his Ph.D at Colorado State University and joined ARS in 1968,
where, in 1981, he became Research Leader of the Water Management Unit.
Heermann derived the mathematical formulation to describe the hydraulics of center
pivot irrigation systems, developed a computer program for pivot evaluation and
design, and derived methodology for computing uniformity of irrigation by center
pivots. With more than 150 technical publications and more than 100 technical pre-
sentations at national and international meetings, Heermann is recognized internatioi
ally as an authority on center pivot irrigation and precision farming.
