“…Tilt tests can estimate the transition from stable to unstable slope angles. However, Samson et al [38] report that its primary disadvantage is testing steeper slope angles greater than the stable-unstable transition threshold boundary, making it unsuitable for low-lying slope angles.…”

“…The review discussed the commonly adopted computer programs for investigating rainfall seepage in unsaturated slopes. A review of the modelling approaches in slope stability was conducted by Samson et al [38] with a focus on block toppling and highlighted milestones in the modelling techniques. However, the study emphasised chronological developments in physical, modelling and analytical methods on block toppling stability analysis, with limited attention to the methods and requirements in numerical and physical modelling in terms of slope materials, scaling laws and physical test apparatus.…”

An extensive evaluation of published articles suggests a lack of research on a systematic literature review relating to physical modelling techniques, developments and application in slope stability studies. However, there is growing interest in using physical model tests in slope stability investigations. The present study systematically reviews the methodologies and applications of physical modelling in slope stability research. The Scopus database was used to identify relevant studies which employed physical model tests in slope stability investigations. A combination of fifteen keywords was used to identify relevant articles. A PRISMA-P method for conducting a systematic review was adopted. Articles were screened and analysed, and extracted data were re-organised using an Excel sheet. Data relating to research objectives, physical model test techniques, instrumentation, scaling laws, numerical modelling, results, and findings were extracted and analysed. The systematic review highlights gaps requiring further studies, particularly in slope reinforcements using vegetation and strength deterioration of reinforcements performance under repeated loading exposures. It is found that scholars have not fully addressed the influence of loss of water on pore water regimes and its impact on stability when vegetation is applied as reinforcements. It is also found that the development of slope materials for soil slopes in physical model tests relies on the artificial development of such materials with minimal consideration of their long-term behaviour. Although other options, such as bio-cementation and desiccation techniques, which simulate the natural environment of the slopes, are neglected in slope material development, the present study recommends that future studies consider such techniques.
