EFFECTS OF CANAL AUTOMATION ON REDUCING GROUNDWATER EXTRACTION WITHIN IRRIGATION DISTRICTS: CASE STUDY OF QAZVIN IRRIGATION DISTRICT^†

Abstract

The impact of upgrading irrigation canal water distribution and delivery systems on reducing the pumping of water from aquifers was investigated. Consequently, energy consumption and carbon emission reduction were investigated. For this purpose, a decentralized integrated control system and a centralized control system were designed. The arrangements were tested on the main canal of the Qazvin Irrigation District under a water shortage scenario. In this research, the centralized automatic control system was satisfactorily implemented in water distribution under the water shortage scenario. The decentralized control system (PI) did not show significant operational performance. According to the results, obtained values of the index of adequacy by upgrading utilization to decentralized automated control systems (PI) were 70 and 77% for the centralized automated control system. Accordingly, the reduction in harvesting from the aquifer was 69.7 and 71.5%, respectively, the reduction of energy consumption was 54.5 and 63.7%, and greenhouse gas emission reduction was 52.4 and 62.5%. © 2019 John Wiley & Sons, Ltd.

Developing Internal and External Proportional Integral Derivative Water Surface Controller in HEC-RAS

“…They found that the reinforcement learning-based proportional-integral controller tuning method outperformed both integer and fractional order proportional-integral controllers. The effects of canal automation on the improvement of water distribution and delivery systems of irrigation canals were investigated [26]. For this purpose, a decentralized and a centralized control system were designed.…”

Prioritization of agricultural water distribution operating systems based on the sustainable development indicators

“…Mismanagement of surface water distribution in many agricultural districts has led to an uncertain and unstable agricultural water supply (Babaei et al, 2018;Hashemy et al, 2018). This has led to a growing tendency of farmers to supply agricultural water from groundwater sources, including environmental problems such as the unauthorized withdrawal of static aquifers (Hosseini Jolfan et al, 2019), subsidence of agricultural plains, the decline in groundwater quality (Fard et al, 2021), salinization and waterlogging, soil erosion, and pollution of rivers and lakes (Monem & Hashemy, 2011). Therefore, upgrading the current agricultural water management to increase sustainable production of food products with minimum water loss is essential for reliable development in agriculture.…”
