Asset management for the group of agricultural faclities based on the risk for soil erosion using the data assimilation

数据同化技术、土壤表层/内部侵蚀数值模式和地震灾害风险已被推广应用于土壤结构作为农业设施的功能诊断，例如，灌溉池塘的堤岸。在假定灌溉池塘群是社会资本/资产，提供社会效益的前提下，结合资产管理、成本效益和公共账户等经济学概念，建立了灌溉池塘群资产管理系统。该系统是在现有的农业设施库存管理系统的基础上扩展而成的，维护着农业用水网络。它也可以应用于民用和地球资源，例如，堤坝

The data assimilation technique, the numerical model for surface/internal soil erosion and the risk for earthquake damage have been extended and applied to the functional diagnosis for the soil structure as the agricultural facility, e.g., the embankment of irrigation pond. The asset management system for the group of irrigation ponds has been developed combining with the economical concept of asset managament, cost-benefit and public account under the assumption that such facility are social capital/asset supplying the social benefit. This system is extended from the existing the stock management system for agricultural facility and maintains the network of agricultural water use. It can also be applied to the civil and earth resources, e.g., the levee.
