River embankments stability is a key aspect in geohazard assessment and underestimating its failure risk may result in unexpected and severe damages. Changes in hydraulic and climatic boundary conditions are responsible for transient water flow within the embankments, consequently the related soil water content and pore-water pressure distributions vary with time. Therefore, it is crucial to investigate their hydraulic and retention behaviour in order to assess in a reliable way the safety margins towards instability mechanisms. To obtain a realistic estimate of key variables in time and space, as a function of external conditions, a combination of field measurements, laboratory testing and suitably calibrated numerical analyses should be used. To achieve this purpose, a full-scale monitoring system was implemented on a cross section of an embankment along the river Secchia (Modena, Italy), mainly measuring the pore-water pressure (including suction) and the water content at different depths. A relatively large variety of different sensors have been installed, to compare their performance in terms of robustness and reliability, and collected data have been interpreted with the help of laboratory and field geotechnical characterisation. The article describes such system and the sensors used, their capabilities and the installation techniques, resulting in quite innovative solutions for the specific application. The spatial variability of the monitored variables is also finally presented and discussed. The proposed integrated monitoring system, which aims at making use of affordable and commercially available sensors that can be therefore installed along extensive river stretches, appears a fundamental starting point to assess potential risks of such geotechnical infrastructures in real-time and to devise well-balanced related mitigation measures.

河流路堤的稳定性是地质灾害评估的关键方面，低估其破坏风险可能会导致意想不到的严重破坏。水力和气候边界条件的变化是堤坝内瞬态水流的原因，因此相关的土壤含水量和孔隙水压力分布随时间变化。因此，至关重要的是研究它们的水力和保持性能，以便以可靠的方式评估对不稳定机制的安全裕度。为了获得时间和空间上关键变量的真实估计，作为外部条件的函数，应结合使用现场测量，实验室测试和适当校准的数值分析。为了达到这个目的，在塞奇亚河（意大利摩德纳）沿路堤的横截面上实施了一个全面的监测系统，主要测量孔隙水压力（包括吸力）和不同深度的水含量。已安装了相对大量的不同传感器，以比较它们在鲁棒性和可靠性方面的性能，并且借助实验室和现场岩土工程技术对收集到的数据进行了解释。本文介绍了这种系统和所使用的传感器，它们的功能以及安装技术，从而为特定应用提供了非常新颖的解决方案。最后还将介绍和讨论所监视变量的空间变异性。拟议的综合监测系统，
