Description

<p>In this study, a model embankment slope simulating vegetation work was constructed with sandy soil to clarify the runoff and infiltration characteristics of rainfall in summer and snowmelt water in spring. The soil boxes that were used had structures to collect water that infiltrated the embankment slope and water that ran off the slope separately. The soil boxes were mounted on a load cell to make it possible to measure the mass change of the entire equipment. Based on the measurement results during the summer season, it was confirmed that the slope with turf work allowed much rainfall to run off as surface water compared to the bare ground slope. Based on the measurement results during the snowmelt season, it was observed that snowmelt water could not deeply infiltrate the bare ground slope, the extreme surface layer became saturated, and the sediment flowed.</p>
