Evaluation of time response of GMS for soil suction measurement [PDF]
MATEC Web of Conferences, 2021 The Granular Matrix Sensor (GMS) is an indirect method for soil suction measurement. Since GMS is comparatively inexpensive, robust and usually provide continuous soil suction data, it is a natural candidate for civil engineering practice. The sensor has
