    The mathematical model which can simulate inundation process in the urban areas due to heavy rain has been developed. The problems of model are to devise the configuration of the grid and to consider buildings, sewage system, streams etc. In this study, the numerical simulation was conducted to reconstruct the Shin-river breach caused by Tokai heavy rain in September 2000. This model employed the ground elevation as the initial condition and the overflow discharge at breach point as the boundary condition. Governing equations are 2-D continuity and momentum equations to simulate urban overland inundation. The result of the numerical simulation was represented by GIS and compared with the field data obtained by the questionnaire. These results indicate the accuracy of this inundation simulation and are helpful in flood management in the future.

    Sufficient investigation of flood flow is very important to protect an urban area from the flood disaster. Because flood flow is boundary condition for analysis of the overland flood flow, flood flow must be simulated in detail. In this study, the flood flow situation in the SHOUNAI River due to the heavy rain in Tokai district is simulated. This model consists 2D model for sea region and 1 D model for river. Though the problem of roughness coefficient remains unsolved, the computed results show good agreement with the observed water level. The control effect of Otai retarding basin in the SHOUNAI River is evaluated targeting heavy rain in Tokai district. It is shown that the control volume of Otai retarding basin is very small against the discharge of the SHOUNAI River during the Tokai heavy rain, there fore, the height of dike for Otai retarding basin must be evaluated for peak-cut.

    As the prevention of all water disasters by using of structural measures is very difficult, the present task is to construct non-structural disaster measures as well as the usual structural ones. The importance of overland flood flow analysis increases for examination of these various counter measures. The aim of this study is to develop the synthetic system for analysing water phenomenon in river, sea and urban region in flooding. The heavy rain in Tokai district is treated in this study. The suitable distribution of inundation water depth is obtained in the inundation states of the urban area. From the simulation results, the validity of the numerical analysis models systematized here and the effect of the sewer system in flood is discussed.

    In order to collect basic data of the arrangements for rehabilitation support system of the flooded houses, we investigated the rehabilitated condition of flooded houses caused by Tokai Heavy Rain. We found as follows; (1) over 50 percent of houses were flooded above the floor over 1 meter high, (2) over 90 percent of the flooded houses were repaired but over 30 percent of repaired houses still have unrepaired parts and (3) the major problem with the sufferers is the shortage of the money that is to be applied to the repair of their houses because they should recover their lives first.

    情報システムの重要性は益々増大しているが,東日本大震災後の調査でも万一に備えた対応を考える事業継続計画の策定が必ずしも十分ではない。経営トップの無関心や最初から100%完璧な計画の策定を想定しているためとも思われる。本稿では,守るべき情報資産と事業継続を脅かすリスクについて考察した。主なリスクである大規模地震や台風・集中豪雨,テロ,その他(突発的大規模停電)について,事業継続を考える上で必要な事柄を過去の知見から得られた内容について考察した。事業継続計画の文書化に役立ち,机上や実践的訓練に役立てるものと考えている。文書化と訓練の相乗効果が,事業継続計画策定のキーポイントになる。

    In order to guide the evacuation of inhabitants in times of disaster, there is an official evacuation announcement. However, it has been found that not all inhabitants actually evacuate when such an order is announced. In order to heighten the effectiveness of the evacuation guidance system, it is necessary to grasp the decision-making mechanism of inhabitants in times of disaster.
    In the time of flood disaster, it is expected that inhabitant's decision-making of evacuation behavior is influenced by the situation of the circumferences, such as the state of flooding, the evacuation announcement, and so on. Therefore in this research, we examined how to sharpen evacuation procedures by analyzing inhabitant's decision-making of evacuation behavior in the heavy rainfall disaster in Tokai district.

    In a flood disaster, it is thought that the quantity of the household-goods damage is prescribed by the depth of flood. But household-goods damage can be reduced by preparing against flood disaster and preserving household goods during flood disaster. However, it is expected that progress of the flood affects the way of preservation action and inhabitants have to choose either preservation action or evacuation behavior in the time of the flood disaster.
    In this study, we grasp the actual condition of household-goods damage in heavy rainfall disaster in Tokai District in 2000. Then, we clarify the effect of preparing against flood disaster and preservation action during flood disaster to damage. Moreover, we analyze the relation between preservation action and progress of flood and between preservation action and evacuation behavior.
