Non-invasive detection methods for subsurface drainage systems: A comparative review

Agricultural Water Management, 2024, vol. 304, issue C

Abstract: The widespread use of subsurface drainage systems in agricultural landscapes over the last century has significantly enhanced land productivity, particularly in humid regions. However, many drainage systems have deteriorated or become non-functional, posing challenges in their maintenance and precise localization. Apart from this, agricultural drainage has also raised environmental concerns due to potential nutrient leaching and water quality issues over time. This review explores the state of the art of various methods to detect and map subsurface drainage networks, considering the impending complications associated with aging drainage infrastructure.
