10月28日に、椋木俊文教授（大学院先端科学研究部）が世話人となり、第131回IROASTセミナーが、開催され、香港科技大学（HKUST）所属のAnthony LEUNG教授による講演がおこなわれました。
"根土の力学：最近の進歩"と題した講演では、不飽和根系土の水理力学的挙動に関する最新の科学的発見と、バイオエンジニアリング斜面の工学的設計への影響について報告されました。
このセミナーはX-Earth Centerと共催で開催され、多くの学生や教員が参加しました。

The 131st IROAST Seminar was held on October 28 under the organization of Prof. Toshifumi MUKUNOKI (FAST, Kumamoto University/ Head of the X-EARTH Center) and featured a lecture by Prof. Anthony LEUNG of the Hong Kong University of Science and Technology (HKUST).

His talk, entitled "Mechanics of Rooted Soils: Recent Advances," reported on the latest scientific discoveries regarding the hydrodynamic behavior of unsaturated root soils and their implications for the engineering design of bioengineered slopes.

The seminar was co-organized with the X-Earth Center and was attended by a large number of students and faculty.

３．講演者・演題 （Speaker &Title）：
 Prof. Anthony LEUNG, The Hong Kong University of Science & Technology
“Mechanics of rooted soil: recent advances”

４．概要（Summary）： Characterising the hydromechanical properties of unsaturated rooted soils is crucially important to correctly determine the vegetation effects on seepage and stability of bioengineered soil slopes. Understanding the engineering behaviour of rooted soils requires knowledge from pore-level physical soil-root mechanical interaction, which is however lacking in the current state-of-the-art. This presentation will report the latest scientific discoveries of the hydromechanical behaviour of unsaturated rooted soils and their implication to engineering design of bioengineered slopes. The first part of the presentation will focus on the mechanical anisotropy behaviour of rooted soils, in terms of both shear strength and shear modulus. New microstructure fabric anisotropic models will be introduced to explain several new experimental phenomena when subjected to different stress paths. The second part of the presentation will report the advanced use of artificial intelligence (AI) to aid the discovery of the pore-level soil-root-water interaction, in order to explain the underlying mechanisms of root exploration on the water retention behaviour.
