Preface and acknowledgments
In 1988 Agro Engineering conducted the small-scale irrigation
training for both pre-service and in-service Volunteers working in irrigation
development in Honduras. One of the major problems encountered during the
training was the lack of appropriate reference materials applicable to
small-scale irrigation development. There are numerous references available for
irrigation, but most have been designed for developed country conditions or
specific irrigation problems in developing countries. Thus the idea of producing
a good training manual with an accompanying reference manual was born.
The content and scope of the project were discussed with Mr.
Jaime Henriquez of OTAPS and Mr. Alfonso Barahona, the APCD who directed the
irrigation training programs in Honduras. The outline and scope of work were
reviewed and modified a number of times, and in September of 1991 Agro
Engineering was asked to produce the manual.
Agro Engineering assembled a team of professionals with over 40
years combined experience in irrigation to write the manual. The authors have
worked in over 20 countries in Asia, Africa, and Latin America with Peace Corps,
CARE, USAID, universities, and several grassroots organizations. Together with
Peace Corps personnel from OTAPS they further refined and amplified the outline.
The focus of the training manual was to be on Volunteers who do
not have formal training in irrigation but who do have some math skills and
knowledge of agriculture. Thus the Volunteers would be agronomists,
agriculturists, engineers, and even business majors. The individuals who design
and manage irrigation projects should all be able to use basic scientific
calculators to add, subtract, multiply, divide, find square roots and averages.
All of the authors have worked on projects where pipelines have failed,
structures have been undersized and washed out, or other problems have developed
because of a lack of basic irrigation knowledge on the part of the
irrigationists. Thus the manual was developed to serve the needs of the
agricultural Volunteers working with irrigation.
A word about the authors:

Irrigation Scheduling: A Training Manual for the International Irrigation
Jim Tolisano is a watershed resource specialist with extensive
experience in training with Peace Corps, CARE, USAID, and various other
entities. He has developed a number of training publications.
Keith Crane is an agricultural engineer specializing in
irrigation. He spent three years as a Peace Corps Volunteer working with
irrigation in Honduras, then served an additional year in Bolivia. He designed
and conducted the Hillside Agriculture course for Peace Corps in Honduras in
1991 and assisted in the training of irrigation Volunteers in 1988.
Lee Wheeler is an agricultural engineer. He has served in the
West Indies in Peace Corps working with both irrigation and conservation. He was
an irrigation engineer with the Soil Conservation Service. His 14 years of
experience in irrigation also include irrigation development work in Guatemala
and Honduras. He has designed and conducted a number of irrigation training
programs for such entities as the International Irrigation Center and the Peace
David Radtke is an agronomist who worked as a Peace Corps
Volunteer in Guatemala for five years. During this time he designed several
small-scale irrigation systems. He has 8 years experience as an irrigation
Maya ter Kuile is an agronomist who has worked and lived in
several Latin American countries including Guatemala, El Salvador, Costa Rica,
Honduras, The Dominican Republic, and Mexico. She has conducted a number of
training programs with the International Irrigation Center. She trained Peace
Corps Volunteers in irrigation agronomy during 1988.
The authors wish to thank a number of other people who provided
valuable input to the manual:
-Special thanks go to Mr. Gaylord Skogerboe, Director of the
International Irrigation Center who provided valuable assistance on the content
and format for the manual.
-Ms. Amy Benner, another Returned Peace Corps agricultural
Volunteer working with Agro Engineering. Her input and assistance in bringing
the manual to its final form is greatly appreciated.
-Mr. Scott Nelson, agronomist; Mr. Audie Cox, irrigation
technician; and Ms. Nancy Berryman, secretary; who spent numerous hours on the
various drafts of the manual.
-Mr. Jaime Henriquez, who saw the value of the project and was
able to prioritize the work before he left Peace Corps.
-Mr. Alfonso Barahona, APCD, whose tireless example and
dedication resulted in a very successful irrigation program in Honduras.
-Numerous reviewers, professors, and consultants who provided
valuable constructive comments and
