Modelling the Spatio‐Temporal Effects of Water Level Control in an Agricultural Collector Ditch Network

Irrigation and Drainage, EarlyView.
ABSTRACT The study focused on modelling open channel flow in an agricultural ditch network. The objectives were (1) to set up a computational tool to explore the hydraulic impacts of water level control in a collector ditch network and (2) to test the effects of damming height and ditch flow resistance on the water level and its relation to field ...

Transmission Water Losses at South African Irrigation Schemes: A Case Study of the Vaalharts Irrigation Scheme

Irrigation and Drainage, EarlyView.
ABSTRACT Irrigation water supply is under scrutiny because of dwindling water resources. Most irrigation water in South Africa (SA) is transmitted by canals. Transmission water loss (TWL) accounts for 12% of the irrigation water losses in SA. Therefore, there is a need to investigate and understand the major parameters influencing TWL at Vaalharts ...

A Novel Approach as a Smart Irrigation Decision Support and Management System Providing Environmental Optimization in Sustainable Irrigation Management: ENORASIS

Irrigation and Drainage, EarlyView.
ABSTRACT ENORASIS has been developed as a real‐time smart irrigation decision support and management system consisting of weather forecasting systems based on satellite observations, irrigation optimization techniques and wireless sensor networks. This study revealed that irrigation could be managed with ENORASIS without a significant decrease in ...
