Implementation of a slope stability method in the CRITERIA-1D agro-hydrological modeling scheme

The data are from the paper that presents the implementation of a slope stability method for rainfall-induced shallow landslides in CRITERIA-1D, which is an agro-hydrological model based on Richards’ equation for transient infiltration and redistribution processes. CRITERIA-1D can simulate the presence and development of roots and canopies over space and time, the regulation of transpiration activity based on real meteorological data, and the evaporation reduction caused by canopies. The slope can be considered composed of a multi-layered soil, leading to the possibility of simulating the bedrock and of setting an initial water table level. CRITERIA-1D can consider different soil horizons characterized by different hydraulic conductivities and soil water retention curves, thus allowing the simulation of capillarity barriers. The validation of the proposed physically based slope stability model was conducted through the simulation of the collected water content and water potential data of an experimental slope. The monitored slope is located close to Montuè, in the north-eastern sector of Oltrepò Pavese (northern Apennines—Italy).

本数据集源自一篇学术论文，该论文提出了在CRITERIA-1D模型中实现降雨诱发浅层滑坡斜坡稳定性分析方法的研究。CRITERIA-1D模型是一款基于理查兹方程（Richards’ equation）的农业水文模型，用于模拟非稳态入渗与水分再分布过程。该模型可模拟根系与冠层在时空维度上的分布与演化过程，基于实测气象数据调控蒸腾作用，并模拟冠层带来的蒸发抑制效应。该模型可将斜坡概化为多层土体结构，支持基岩模拟与初始地下水位设置。CRITERIA-1D模型可针对不同土壤层次设置差异化的导水率与土壤持水曲线参数，进而实现毛细屏障的模拟。该论文提出的基于物理过程的斜坡稳定性模型，通过对某试验斜坡实测的土壤含水率与水势数据开展模拟，完成了模型验证。该监测斜坡位于意大利北部亚平宁山脉的奥尔特雷波帕韦塞（Oltrepò Pavese）东北部区域，临近蒙图埃（Montuè）镇。
