柯克科伊阿尔维洪水公园
Kirkkojärvi Flood Park
柯克科伊哈维公园是埃斯波河谷的一片绿色绿洲。公园的理念是基于水的动态运动和地面的雕刻。位于该地区的前湖作为一个象征性的、开放的洪水场被带到了景观中。河水泛滥时，湖面又恢复了原貌。
Kirkkojärvi Park is a green oasis in the Espoo river valley. The idea of the park is based on the dynamic movement of the water and sculpting the ground. The former lake that was at the area was brought to the landscape as a symbolic, open flood field. The lake returns to the landscape when the river floods.
Kirkkojärvi Park is located in central Espoo, the second largest city by population in Finland. The park used to be a lake but was drained in 1959 with the building of Finnish National Road 1. The River Espoonjoki runs through the scrubby wetlands of Kirkkojärvi.
The Espoonjoki floods frequently because of meltwater in the spring and heavy rainfall in the autumn. In addition, climate change has made flooding during the winter more common. Flooding blocks the light transportation routes and playing fields in the riverside area.
上面的小数字显示了洪水管理作业前Kirkkojärvi的四个不同水位。左边的第一幅图显示了平均水位，这是该地区的平均水位高度。右边的最后一幅图显示了水位上升如此之高的情况，它覆盖了所有的运动场和河边路线，并到达了低洼地上建造的几座建筑物。例如，水位+4.73 msl是Kirkkojärvi地区每二十年发生一次洪水的计算水位。
The small figures above present four different water levels in Kirkkojärvi before the flood management operations. The first figure on the left shows the mean water level, which is an averaged height of the water in the area. The last figure on the right shows occasions where the water level rises so high that it covers all the playing fields and the riverside route and reaches several buildings built on low-lying ground. For example, level +4.73 msl is a calculatory water level of floods occurring once in twenty years in Kirkkojärvi area.
洪水管理主要通过稳定和抬高河岸路线的关键部分来实现。这样，洪水泛滥的埃斯波约基就可以留在河床中，河边公园大部分时间都可以使用。上图和下图显示了在Kirkkojärvi公园进行的程序。
The flood management was achieved mostly by stabilising and raising critical parts of the riverside route. In this way, the flooding Espoonjoki would stay in its riverbed and the riverside park can be in use most of the time. The figure above and cross-sections below show the procedures undertaken in Kirkkojärvi Park.
水是新娱乐区的核心，也是规划中的一个挑战。河床被改造和种植，河边增加了新的座位。Kaivomestari广场的木制了望台可以看到河谷的全景。它还隐藏了下面的大型雨水管道。
The water is the heart of the new recreation area, as well as a challenge in planning. The riverbed was reshaped and planted, and new seating places were added to the riverside. The wooden lookout deck in Kaivomestari Square offers a panoramic view of the river valley. It also hides the big stormwater pipes underneath.
Kirkkojärvi公园的洪水和不断变化的景观使它成为一个特别令人兴奋、有趣和难忘的地方。公园最南端的小路将柯克科伊哈维公园分为两个截然不同的区域：北部埃斯波约基河的开阔漫滩，以及南部和东部的功能空间。
The floods and the constantly changing landscape in Kirkkojärvi Park make it a particularly exciting, interesting and memorable place. The path in the southernmost part of the park divides Kirkkojärvi Park into two distinct areas: the open floodplain of the River Espoonjoki in the north and the functional spaces in the south and east.
总体思路是创建一个以地形设计和动态水流为中心原则的生态规划。公园小径作为一条象征性的老柯克科伊哈维海岸线的作用通过天然石头、草地和河边植被得到了强调。新的宗派种植的树木强化了空间感，并为河谷的远景提供了边界。
The overall idea was to create an ecological plan in which the design of the terrain and dynamic water movements are the central principles. The role of the park path as a symbolic old Kirkkojärvi shoreline was emphasised with natural stones, grasses, and riverside vegetation. New sectorally planted trees intensify the spatiality and give borders to the long views of the river valley.
The upper picture below shows the Espoonjoki in its normal state. The picture below it is edited to showcase a level +4.73 msl flood in the improved, flood-resilient Kirkkojärvi Park.
Kirkkojärvi Park also has an important role in raising environmental awareness. The flood management solutions and dynamics of the environmental processes are brought to the attention of park-users by locating information signs and water-level indicator posts along the park path.
