Soil moisture causes dynamic adjustments to root reinforcement that reduce slope stability
In steep soil-mantled landscapes, the initiation of shallow landslides is strongly controlled by the distribution of vegetation, whose roots reinforce the soil. The magnitude of root reinforcement depends on the number, diameter distribution, orientation and the mechanical properties of roots that cross potential failure planes. Understanding how these properties vary in space and time in fores...
متن کاملDynamic modeling of root water uptake using soil moisture data
In this work a dynamic model of water uptake from plants growing in naturally vegetated areas subjected to a rainfall and evaporation time series is described. The model results are compared and contrasted with popular pre-existing models. Also, the effects of the uptake pattern on the movement of water across multiple soil layers are also analyzed. The results showed that contrary to common mo...
متن کاملSoil moisture storage and hillslope stability
Recently, we presented a steady-state analytical hillslope stability model to study rain-induced shallow landslides. This model is based on kinematic wave dynamics of saturated subsurface storage and the infinite slope stability assumption. Here we apply the model to investigate the effect of neglecting the unsaturated storage on the assessment of slope stability in the steady-state hydrology. ...
متن کاملThe application of dynamic programming to slope stability analysis
The applicability of the dynamic programming method to two-dimensional slope stability analyses is studied. The critical slip surface is defined as the slip surface that yields the minimum value of an optimal function. The only assumption regarding the shape of the critical slip surface is that the surface is an assemblage of linear segments. Stresses acting along the critical slip surface are ...
متن کاملAustralian Root Zone Soil Moisture: Assimilation of Remote Sensing Observations
Knowledge of temporal and spatial variation in root zone soil moisture content across Australia is vital for a wide range of environmental and socio-economic activities. However, such information is not currently available, due to an inability to monitor with ground-based point measurement techniques at an appropriate spatial resolution, and the uncertainty associated with land surface model pr...
