INTRODUCTION

Canal Automation is becoming widely used to improve the operation of canal systems and to conserve water. Automatic control systems are installed on most new canals, and many older canals are being modernized with data collection, telemetry, and control equipment to help canal operators better manage their water.

Canal Model Panorama

This training course on canal operations and control methods is taught by the Bureau of Reclamation's Hydraulic Investigations and Laboratory Services Group in Denver, and has been offered each year since 1996.  The course covers modern methods to upgrade the operations of existing canals, including canal automation techniques and equipment.

The curriculum includes a combination of classroom discussions, equipment demonstrations, and laboratory workshops that target canal operators, watermasters, engineers, and other technical staff.  Course topics include:

The training course features a new model canal facility in Reclamation's hydraulics laboratory. This laboratory model is a 300-foot-long canal made from clear acrylic Plexiglass and aluminum with motorized control gates, turnouts, a long-throated flow measurement flume, and an inverted siphon. It is fully instrumented for remote monitoring and control of water levels, gate positions, and flows, with both manual and automatic control capabilities. The model canal was designed specifically to provide training through "hands-on" workshops where students experience different canal operating techniques and control methods. <more photos>

WHO SHOULD ATTEND

Modern Methods in Canal Operation and Control is designed for watermasters, canal operators, managers, and engineers who are interested in improved canal operations. The instruction is geared towards people who want to learn through active participation and "first hand" experience with canal operations and instrumentation.

Both of this year's sessions will offer a basic curriculum targetting first-time students in Reclamation's canal automation training program. Although students should have some experience with irrigation canal systems, an extensive technical or engineering background is not required.


TRAINING STAFF

Workshop instructors are engineers and scientists with extensive experience and knowledge in the areas of canal automation, operation and control. Principal instructors are Dave Rogers, Bob Einhellig, Tony Wahl, and Tracy Vermeyen. These Bureau of Reclamation engineers have conducted many training programs for Reclamation and other organizations. Some lectures and vendor demonstrations will be given by industry experts from outside Reclamation.

PUBLICATIONS

Presentation notes and other course materials will be compiled into a notebook and distributed to all participants at the start of the Workshop. As a supplement to the course notes, participants will also receive complementary copies of Reclamation's new Water Measurement Manual (third edition) and the Canal Systems Automation Manual, Volumes 1 and 2. 


REGISTRATION

Participants should register using the enclosed registration form. There is no tuition fee for this workshop.

To maximize the benefit for each student, each workshop session is limited to 15 participants. If you find that you are unable to attend, please give us your cancellation notice as soon as possible. A substitute from your organization can take your place, or your slot will be offered to the next person on our waiting list.


TRANSPORTATION & LODGING

Course participants are responsible for their own transportation and lodging arrangements and costs. The workshop is held in Building 56 at the Denver Federal Center, on the west side of the Denver metropolitan area. Several hotels are located nearby; some of these have complementary van service to the Federal Center. Taxis or shuttle service from Denver International Airport (DIA) to hotels can be arranged at DIA.
