    Ministry of Transport has worked out new policy which aims at creation of comprehensive port and harbor space. One of very important space for vessels is safaty harborage. Port develoment and expansion for the increase of calm space seems to enable the creation of mooring harborage. So we have carried out simulations on mooring vessel in stormy weather on the four wharves of port of Tokyo. The results are as follows.

    It is still difficult to utilize the present wharves as harborage. However, a small design change of mooring equipments enables the creation of safety harborage space . And this paper examines the spacing and capacity of mooring equipments, bollard and fender.

    In the environmental improvement for smoother popular utilization of water space (public access), which has been vigorously pushed for in the waterfront area in recent years, satisfaction of three requirements is considered to be important. These requirements are : (1) accessibility of the waterfront area (accessibility); (2) the easy accessiblity of inst.itutions for citizen's utilization (usability); (3) capability of approach to the waterfront and ensured view of the coastline (openness) . This study aims to evaluate the current state of public access to the waterfront area of the Tokyo Port from the viewpoints of these three requirements.

    The results of accessibility evaluation are that the areas featuring excellent accessibility have increased ; that accessibility of the facilities used by citizens has also enhanced with regard to usability; and that improvement of these two factors was therefore ascertained. As for openness, on the other hand, accessibility is good, but the open coastline has not increased measurably. As such, future improvement in this respect is awaited .

    An important condition for the development of towns which offer rich environments for comfortable lifestyles to residents is the enjoyment of the history and culture which embody the character of a particular region . In this paper, the authors examine "regional matsuri (festivals)" as a way of comparing the relative potential for cultural succession of different regions . Taking geographical environment as an axis of comparison, the authors analyze the structure and historical changes of matsuri, and look for the relationship between these and the cultural elements which have been succeeded in matsuri.

    The harsher the geographical environment of a region is, the older the origin of its matsuri and the smaller the probability of interruption of matsuri at sometime in the past are. Moreover, in such regions, the number of participants from distant areas is greater, as is the number of unique elements in the matsuri which have been succeeded. The majority of matsuri which began after the Second World War are held in summer to increase the participation of local residents . The potential for cultural succession is greatly influenced by both the geographical environment and the managing method of matsuri.

    In the future development of coastal regions, it will be necessary to make efforts conserving the valuable natural coasts and/or creating new appropriate environments in order to keep the ecological systems as natural as possible. The purpose of this study is to clarify the relationship between the environmental changes accompanied by the developmental works and the natural inhabitants for the creation of new environments which and suitable for both human beings and living things.

    One of the most important results of our study is a quantitative understanding of the structural changes of ecological communities formed by living things depended on the changes of habitat environments.

    We have succeeded in divising a new evaluation method which can express the restoration process of inhabit environments using visual presentation. This method which can express the relationship between changing natural inhabits and the living things in course of time is believed to provide a great deal of important information during the conduction of environmental restoration projects.

    The object of the present study is to evaluate the adequacy of various ways of water area use with respect to marine environments taking the case of Hakata Bay. The ways of water area use taken up in the present study are the recreational use such as dinghy yachts, motorboats and water restaurants, the use for fisheries, reclamation, tide land for natural preservation, etc The extent of adequacy of those ways of use are evaluated by comparing the existing marine condition such as wave characteristics , tidal currents, water depth, water quality, sediments, plankton, landscape, etc with the conditions which are required from the above ways of water area use. The extent of adequacy in each location of the water area is scoured and displayed in meshes on the plane map of Hakata Bay, which resulted in an excellent achievement as was expected.

    An economic model on fisheries damages aims to internalize the externalities on fisheries by coastal activities . This paper reviews the fourmula for fisheries compensation in Japan from an economic point of view and systematically presents a logical background of calculation factors. The analysis shows that the current fisheries compensation practices shall be revised based on economic rationales. The validity of the formula has been reviewed from two different, though not incompatible, approaches of the least common multiple method and capital recovery factor method. An evaluation model for fishery damage compensation suggests that the capital recovery cost be included in the fishery operation cost, while the time-adjusted amount are added to the income compensation.
