A Study on the Potential of Historical Weirs as Waterfront Space

本研究的目的是评估历史堰作为滨水空间的潜力。在京都的一之井关和高知的幡关这两个案例中，对游客的空间和活动特征进行了调查。还有一个案例，德岛的大州关，已经提前调查。对这些堰的空间和活动进行了比较。三者的涉水活动类型存在差异。认为堰体尺寸和溢流口大小是造成差异的主要因素。提取了各部分的各种活动和空间。通过对各断面的研究，提出了水友好活动的空间因素。这些是从银行的可达性，地板的条件，到水面的距离，河床的条件，和水的深度和速度。堰具有接近河流、体验河中、滨水再创造、与水深度接触的空间潜力。

The objective of this study is to evaluate the potential of historical weirs as waterfront space. The characteristics of both spaces and activities of visitors were investigated in two cases, Ichinoi-seki, Kyoto, and Hata-seki, Kochi. One more case, Daiju-seki, Tokushima, had been investigated in advance. Spaces and activities of these weirs were compared. Differences of types of water-related activities existed among the threes. Size of the weir and overflow were thought to be the factors of the differences. Various sets of activities and spaces in terms of sections were extracted. The spatial factors for water-friendly activities came up from studying the sections. Those were accessibility from the banks, condition of floor, distance to water surface, conditions of riverbed, and depth and speed of water. The weirs have the potentials as spaces for approaching the rivers, experiencing being in the middle of rivers, recreating at the watersides, and contacting deeply with water.
