In this study, two different approaches of infiltration parameters estimation in traditional, variable and fixed alternate furrow irrigation, with and without cutback inflow, were performed and compared. Four usual methods including two-point (Elliott and Walker), Valiantzas one-point, Mailapalli one-point and Rodriguez and Martos optimization methods, as approaches based on advance data, and m...

[1] In this study, two parameterizations for different irrigation techniques have been implemented in a regional climate model. These implementations allow for a comparative study of water use and land–atmosphere interactions associated with traditional flood irrigation—a widespread but highly water-inefficient practice—and water-conserving drip irrigation. Both parameterizations yield realisti...

Surface irrigation is the dominant method of on-farm irrigation in Egypt as well as world wide. Furrow watering is considered as one of the main types of surface irrigation. Most of the cultivated crops are grown under such type of watering. The principal advantage of furrow irrigation is the less irrigated area comparing with that under basin irrigation which equaled total cultivated acreage. ...

Irrigated agriculture has always been relevant to the Aragonese society. The major expansion of irrigation took place during the XX century to promote economic growth and to improve farmers’ social conditions in rural Spain. At present, maintaining irrigation in Aragon is still important because agriculture is linked to a strong agribusiness sector, and because irrigation contributes to avoid d...

The effect of irrigation on the abundance of Empoasca vitis (Göthe) populations was investigated in four vineyards located in northeastern Italy. In two experiments, we compared leafhopper population densities in plots irrigated (micro-spray irrigation system) or nonirrigated. In another experiment, we studied the effect of various irrigation systems on E. vitis populations over two successive ...

Traditional channel irrigation systems in Switzerland are managed on a community basis and have high cultural, touristic and ecological values. However, many irrigation communities disappeared in the last decades. This paper analyzes the factors contributing to the continuation of a still existent irrigation community. Our analysis thus provides insights into how to avoid further losses of thes...

Introduction: A case report of direct vancomycin irrigation as management of retroperitoneal abscess following removal of infected aortic graft. Case Report: A 63-yearold man presented nine years following aortic aneurysm repair with recurrence of aneurysm. At re-operation, aortic graft infection was diagnosed and managed with graft excision, debridement, axillo-bifemoral bypass and prolonged s...

Lowland meadow irrigation used to be widespread in Central Europe, but has largely been abandoned during the 20th century. As a result of agri-environment schemes and nature conservation efforts, meadow irrigation is now being re-established in some European regions. In the absence of natural flood events, irrigation is expected to favour fauna typical of lowland wet meadows. We analysed the ef...
