    Remote monitoring and operation at the Colorado River Irrigation District
    (Colorado State University. Libraries, 2005-10) Ruiz, Victor, author; Navarro, Julio, author; Paredes, Mario, author; Andrade, Bernardo, author; Anguiano, José, author; Delgado, Francisco, author; Begovich, Ofelia, author; Ramirez, Javier, author; U.S. Committee on Irrigation and Drainage, publisher
    The Colorado River Irrigation District is the last irrigation district and water user on the Colorado River. It obtains 80% of the allocated volume to the district from the Colorado River. The inflow to the district presents fluctuations. The first 27 km of the mail canal are used as buffer reservoir. Between 2002 and 2004 to improve water management, the National Water Commission, Mexican federal agency responsible of water reclamation, installed a remote monitoring system for the head control structures. The system was integrated around MODBUS as communication protocol, Lookout from National Instruments as man machine interface, SCADAPack from Control Microsystems as remote terminal units, "The Probe" from Milltronics as level sensors, Transpak potentiometer transmitters for gate opening and MDS 4710 and 4910 radios from Microwave Data Systems for communication. The remote monitoring system installed was complemented with the remote operation of one control structures. The system starts operation on February of 2005. The remote monitoring system reduces the time required to know, to quantify and to correct the flow and level fluctuations present on the head control structures.

    SCADA application on a diversion dam
    (Colorado State University. Libraries, 2007-06) Ruiz, Victor, author; Begovich, Ofelia, author; Villagrana, Eliseo, author; Bernabe, Valetín, author; Romero, Ernesto, author; Ramirez, Javier, author; U.S. Committee on Irrigation and Drainage, publisher
    This paper describes a flow control regulator application in a diversion dam at the Irrigation District 097, "Lázaro Cardenas", Michoacan, Mexico. A Hydropower Company has started to produce electricity during high demand peak hours releasing the daily volume for irrigation in few hours. Downstream of the storage dam, a Diversion dam stores the water released for power and delivers the water as the irrigation district requires under controlled conditions. Because of these changes in operations at the diversion dam a SCADA systems was installed. The measurement and operation equipment integrated for this application consisted in a SCADAPack, the Probe ultrasonic level sensor, gate position sensor and Horizontal Doppler Current Profiler Channel Master as flow meter. The SCADAPacks at the flow meter and diversion dam were connected by low cost radios called Maxstream. To improve the reliability of the systems redundant equipment was installed on gate position, upstream level sensor. For flow measurement reliability the gate equation, calibrated with the H-ADCP data, was used. As a first step a set of rules were introduced to adjust the gate opening to keep the flow at the head of the main canal constant as the level on the diversion dam change. Since the end of 2006 the system is being transferred from a manual system to an automated system.
