Moss Biocrusts Enhance Hydrological Functionality on Engineered Slopes

It includes in-situ and laboratory measurements comparing moss crust-covered soil with adjacent bare soil across three slope positions: bench top (BF), bench surface (BS), and bench toe (BT).

Key data encompass soil physicochemical properties (texture, bulk density, porosity, soil organic matter, macroaggregate content), hydrological parameters (soil water retention curves fitted with van Genuchten model parameters, field capacity, wilting point, plant-available water), and permeability metrics (saturated and unsaturated hydraulic conductivity, sorptivity, water repellency index). Crucially, the dataset features high-resolution X-ray μCT 3D pore network analyses, providing quantitative metrics on macroporosity, pore connectivity, pore-throat characteristics, and coordination numbers.
