Applications of Geosynthetics to Irrigation, Drainage and Agriculture

Abstract

Geosynthetics are man‐made products manufactured to meet specific functions in earthworks and geotechnical projects, such as dams, levees, canals, dikes and other structures commonly found in agricultural engineering. Thanks to the Memorandum of Understanding between the International Geosynthetics Society (IGS) and the International Commission on Irrigation and Drainage (ICID), collaborative efforts are being undertaken to generate awareness of geosynthetics in agriculture. In the Workshop on ‘Applications of geosynthetics to irrigation, drainage and agriculture’ held at the 23rd International Congress of the ICID in Mexico City on 8 October 2017, a group of delegates from the IGS contributed with a series of presentations introducing various functions and applications of geosynthetics. The authors gave an overview of how geosynthetic products are designed and tested to ensure they will fulfil their intended function, focusing on applications to irrigation, drainage and agriculture. A few key considerations were identified as being critical to ensure proper performance of geosynthetic materials, in geotechnical projects in general and in agriculture in particular. The present paper is intended to provide a summary of these presentations. © 2018 John Wiley & Sons, Ltd.

Repensar la Agenda 2030: Tendencias de sostenibilidad

“…Hablando estrictamente del riego como sistema, el PE y PVC son los materiales plásticos mayormente utilizados para condición del agua para riego y drenaje. En adición, se usaron geosintéticos para movimientos de tierras y proyectos geotécnicos: presas, bordos, canales u otras estructuras como parte de un proyecto agrícolas (Blond et al 2018).…”

Sustainable Use of Geosynthetics in Dykes

“…Geosynthetic reinforcement can be incorporated in the embankment to improve stability (Figure 15). Geosynthetic reinforcement placed along the dyke axis can also be used to minimize the length effect [22]. Figure 15.…”

“…Figure 15. The tensile strength provided by geosynthetic reinforcement can prevent the failure of a dyke constructed on a hillside, while reducing its footprint (adapted from [22]).…”

“…Dyke failure prevented by using geosynthetic basal reinforcement. Tension that develops in the reinforcement (red arrows) provides the required stability and reduce embankment settlements (adapted from[22]).…”

International Organisations and the Icid Vision 2030

“…Goal 3 ‘ Facilitate exchange of information, knowledge and technology’ is largely concerned with ICID's internal exchange of information, but this could be extended to other organisation's platforms. For example, ICOLD provides a challenging example of an organisation more receptive to new technologies, such as use of geosynthetics (Blond et al, ).…”
