Contemporary Aspects of Irrigation Tanks, and Management and Conservation Strategies for their Wise-use

日本的触发坦克的当代方面主要是通过对其明智使用的建造管理和保护战略进行实地观察的。该研究的主要水果已被总结为后续。开发了一种新颖的方法来估计食物停机的动态特性，并已证实，即使当他们没有假期储存洪水的时候，他们也没有假期。使用调制解调器控制理论，开发了一个用于互连触发坦克系统的最佳控制/管理模型。在几个真正的触发坦克中复制地震振动，以及安装舱的地震行为是ana-lyzed使用光谱和模型方法。然后，一个尝试是找到一个主要泄漏路径的交易，该交易是在一个过度的触发池中完成的。一种确定海底问题的统计方法也是用随机渗透性归档的一代开发的。使用Percolation理论， furthermore，一种方法是为了重新生成形式“imperous wall”或“flow path”的空间。在触发水箱中对水质量和生物学的现场观察是由产生的，并以所收集的数据为基础，该方法是由水箱从水质量/藻类因素的一个角度归类。通过环境领域的调查，产生了水的繁荣，使之变成了光明。已分析了一个多函数的结构。这是一个演示，即可以用四个主要核心功能结构化的内部功能，并详细描述每个核心功能都与坦克的可持续智慧使用和存在有关。最后，对坦克的管理和保护提出了在多功能坦克的条款中有效的战略。

Contemporary aspects of irrigation tanks in Japan were investigated mainly through field observations in order to build management and conservation strategies for their wise-use. Main fruits of the research are summarized as follows.・Developing a novel methodology for estimating dynamic properties of the food runoff, it was verified that irriga-tion tanks could mitigate flood even when they have no vacancy for storing flood.・Using the modem control theory, an optimal control/management model for interconnected irrigation tanks system was developed.・Reproducing seismic vibrations at a few real irrigation tanks, the seismic behaviors of the embankment were ana-lyzed using spectral and model approaches. And, an attempt to find a transaction of major leaky-path was made at an overage irrigation tank. A statistical approach to confined seepage problem also was developed with generation of random permeability filed. Using the percolation theory, furthermore, an attempt was made to reproduce spatial spanning that forms "impervious wall" or "flow path".・In-situ observations of water quality and biology in irrigation tanks were made, and based on the data obtained, an attempt was made to categorize the tanks from a viewpoint of water quality/algae facets. Through environmental field investigations, causes that generate the water bloom were brought into light.・Structure of multi-functions of irrigation tanks was analyzed. It was demonstrated that the entire function could be structured with major four core functions, and detailed description for each core function was made in relation to sustainable wise-use and existence of the tanks. Finally effective strategies for management and conservation of the tanks were proposed in terms of multi-functioning tanks.
