Irrigation canals are generally made through porous soil formations, since the is loose media – a huge amount of canal water lost to conveyance losses. The situation becomes direr when these losses result in non-beneficial Sindh province Pakistan has more than 70% saline groundwater, such areas not only become unusable but also creates management problems. Perhaps cost-effective way address lin...

In this paper the algorithm for detection of oscillatory control loops developed in Hägglund (1995) is applied to irrigation channels. The water levels in irrigation channels are controlled using mechanical gates. The controller configuration is a decentralized distant downstream scheme where a gate controls the water level upstream of the next downstream gate. The controller is a PI controller...

In this paper, a methodology for the optimal management of a combined irrigation and water supply system based on model predictive control (MPC) is proposed. A controloriented modelling methodology for this type of systems is presented as well. MPC is used to generate flow control strategies from the sources to the consumer and irrigation areas to meet future demands with appropriate flows, opt...

This project proposed an embedded system for automatic control of irrigation. This project has wireless sensor network for real-time sensing and control of an irrigation system. This system provides uniform and required level of water for the agricultural farm and it avoids water wastage. These paper have real time sensing and control of an irrigation system. When the condition of waterin the a...

The use of Precision Agriculture systems is in its infancy in Greece, because of the high fragmented land and the adherence of farmers to traditional farming methods. This paper presents the design, implementation and performance evaluation of an integrated agricultural monitoring and irrigation system using energy-autonomous wireless sensors and actuators. Monitoring and irrigation of the fiel...

Excessive, wasted water has prompted the creation of the Top 10 Water Challenges of Nebraska [1]. 70% of the world’s water usage is related to agriculture [7], more efficient irrigation solutions promise a large benefit for farmers, consumers and the environment. Through a USGS grant, the Cyber-Physical Networking Lab at the University of Nebraska-Lincoln has pledged to complete an autonomous i...

In the proposed Irrigation system IoT is implemented, in this system all the information that are received from the sensors and the various parameters are given to the arduinouno microcontroller as an analog input. A preset value of soil moisture sensor is fixed in microcontroller and also for fencing. When it goes beyond the particular threshold value water is automatically irrigated to the cr...
