 note = {The stock management for irrigation infrastructure has just been adopted to extend the life-span of the infrastructure and reduce the life-cycle costs under the limited budget constraints. For appropriate implementation of the stock management, precise deterioration forecast of infrastructure is required. The typical deterioration of irrigation infrastructure is abrasion of reinforced irrigation canals. Deterioration forecast methods for canal abrasion are developed by using soundness index and arithmetic mean roughness (Ra). Deterioration forecast function and Markovian transition probability model are used for forecasting canal abrasion deterioration with soundness index. Arithmetic mean roughness (Ra) is used for expressing numerically canal abrasion deterioration to minimize errors among inspecting results by inspectors with soundness index.},
