Initiating Scada Projects in Irrigation Districts

Delivering water efficiently through distribution networks is a priority for irrigation districts but often is a difficult goal to achieve. SCADA shows promise of improving operational efficiency, increasing flexibility in the amount and timing of water deliveries, and reducing spills and other losses in distribution networks. However, implementing SCADA in a district for the first time is a difficult process. Districts often do not understand or are distrustful of the technology. They often do not know or understand how their system actually operates, thus making it difficult to design SCADA systems and to determine operational parameters and control algorithms. Selecting equipment that is easy to integrate into district operations is not a simple decision. Simple tasks such as selection of sensors and communication hardware become time consuming because of the need to explain advantages and disadvantages of each component. District boards of directors are normally reluctant to spe...

ARTICLE INFO One of the most important problems facing the agricultural sector, irrigation is indiscriminate and others regularly, causing wastage of large quantities of water, and we will work in this project to solve this problem using the SCADA system, which provides command and control and collect data on irrigation to rationalize and streamline the process of irrigation.
Design, implementation and tuning of an irrigation canal system SCADA

Manuel Rijo
: The paper presents the design, implementation and field tuning of the SCADA system of a Portuguese irrigation canal network upstream controlled with AMIL radial gates and equipped with other Neyrpic devices. In addition of the irrigation district and its hydraulic main system, the paper also presents SCADA architecture, including two synoptics, and their remote terminal units (monitoring and control and monitoring units). The SCADA manual controllers – direct, gate position and gate flow controllers - are defined for the main canals and main distributors intakes, in order to permit a pre-defined flow value or a daily flow schedule achievement. SCADA also monitors outflows from the main canals and main distributors - the most important canal top side weirs and canal terminal weirs. The developed manual gate flow controllers were tuned in the field using collected data readings from two types of acoustic Doppler flow meters. The field procedures for tuning the flow controllers and t...
Meeting irrigation demands in a water-challenged environment

Presented at Meeting irrigation demands in a water-challenged environment: SCADA and technology: tools to improve production: a USCID water management conference held on September 28 - October 1, 2010 in Fort Collins, Colorado.Irrigation districts across the West face economic hardship brought about by increased maintenance costs, reduced water supplies, and a shortage of skilled labor. One opportunity for a district to offset these challenges is by implementing a Supervisory Control and Data Acquisition (SCADA) system. However, historically these systems have been out of the reach of smaller and less-affluent districts because of the large capital outlays required for adoption. Reclamation's Nebraska-Kansas Area Office in cooperation with Reclamation's Hydraulic Investigations and Research Laboratory is working with the Bostwick Irrigation District in Nebraska to create a monitoring and control system suitable to the needs of a small irrigation district with limited resourc...

SCADA System applications

The industrial control systems, which include supervisory control and data acquisition (SCADA) systems, distributed control systems, and other smaller control system configurations such as skid-mounted programmable logic controllers are often used in the industrial control sectors. The SCADA systems are generally used to control dispersed assets using centralized data acquisition and supervisory control. The SCADA systems are also distributed systems that are used to control geographically dispersed assets, which are often scattered over thousands of square kilometers, where centralized data acquisition and control are critical for system operation. They are commonly used in distribution systems such as water distribution and wastewater collection systems, oil and gas pipelines, electrical power grids, and railway transportation systems. In this article, the SCADA system used in the Yuvacik Dam and Reservoir operation, which is located in Kocaeli province of Turkey is reported and the problems associated with the system operation and their solutions are discussed. Keywords: Water resources; The effective and real time control of water resource; Dam management by SCADA; Problems and solutions
SCADA System for Monitoring Water Supply Networks
mohammad heydarian
Water supply represents a vital problem for people, and this imposes the need to know the information regarding consumptions, resources and production. This implies a continuous supervision of the water supply process in order to allow any problem that could appear to be solved, and in the same time, to maintain normal functioning parameters. Proper solutions imply automation and monitoring architectures which contain: a supervision and control system for the real time installation, programmable logic controllers with basic functions (communication, adjusting, measuring, etc.) libraries, communication systems, standard interfaces or dedicated ones with sensors, electrical drive elements, measuring devices, etc. The informatics systems present the possibility of preventing some phenomenon, by analyzing and processing the data, leading to an optimum functioning and to important financial economies. In this way, the paper presents a SCADA system for the monitoring and control of the technological parameters in the water distribution stations, which will allow the optimum functioning of the pumping system, safety and endurance growth in the equipments and installations exploring, and so obtaining efficient energy usage and optimum administration of the drinkable water.
DESIGN OF A SCADA-BASED WATER FLOW AND DISTRIBUTION MONITORING SYSTEM
S. M . Gana, Auwal Imam
The increasing awareness of water management problems has resulted in a need for information in ground water flow and distrib ution. There have been various approaches to design water monitoring networks, some of these designs have not been effective and reliable. Optimization of a monitoring network requires that the system be organized and structured with respect to the number of locations of sampl ing points. Monitoring and control technologies are indispensable for the safe utilization of water. They allow for the surveillance of source water quality, quantity and the detection of threats, thus defining the boundary conditions for the subsequent prevention and providing earl y warning in case of unexpected contaminations or overflow. This paper therefore presents a design of a SCADA monitoring system with a with a radi o telemetry techniques to monitor the distribution and flow of water from the source to some points.
