Development of a concept for a landslide protection system for territories

Landslide processes pose a serious threat to reclaimed land. Typically, existing approaches to landslide protection do not account for the specific of hydro-reclamation systems, creating a conflict between regulating soil moisture regimes and ensuring slope stability. The aim of this study was to develop a concept for the systemic integration of anti-landslide measures with land improvement practices, based on the methodology of systems analysis and synthesis. The research analyzes the landslide life cycle – from the latent stage to the critical stage – and identifies the types of protective measures corresponding to each stage. A key result of this study is the architecture of a regional information and analytical Decision Support System (DSS), that integrates three tiers of landslide risk management: operational (an early warning system based on soil moisture data, with a lead time of up to 24 hours), tactical (planning measures for periods up to one year), and strategic (risk and program management for 1–5 years). A scheme for integrating anti-landslide and land reclamation systems is proposed, based on the creation of a unified drainage network and coordinated groundwater level management to maintain it below the sliding surface. The scientific novelty of this work lies in substantiation a methodology for selecting an optimal suite of protective measures that considers not only geomechanical factors, but also the objectives of agricultural land reclamation. The practical significance lies in the fact, that implementing the proposed concept will enhance the efficiency of engineering protection, reduce the tehnogenic load on slopes, and optimize costs through the integration of anti-landslide and hydroreclamation measures. The obtained results are intended for direct application in the development of design and working documentation concerning the engineering protection of territories for capital construction projects located on sloping areas.
