泰国商业街里的“溪谷步道”

"溪谷步道"距离Megabangna主广场较远。该项目实践了置身水中的想法。景观设计采用相同的策略，使用蜿蜒的地形种植池来容纳现有的树池，它们变成了岛屿的田野，定义了两者之间的空间。除了上述限制之外，真正的挑战是水如何从一侧流向另一侧？团队的目标不是创建一个镜面水景或一个小池。而是创造一条连续流动的水域。这样就可以保持轻薄的水面，换言之相对现有结构重量更轻。对于轻薄的水面，水必须具有运动性。否则就会看起来像一潭死水。

 ‘Stream Valley Walk’ is located further from the main plaza of Megabangna. The initial idea of sitting in the water is explored here. Landscape design employs the same design strategy by using meandering topographic profile planters to accommodate the existing tree pits. These planters become fields of islands that define spaces in between. The real challenge other than the constraints mentioned above is how water can flow from one side to the other? The goal is not to create a reflective pond or a small pool. Rather, the goal is to create a stream of water that flows continuously. So that we can keep a thin water profile, in other word, less weight for the existing structure. With the thin water profile, water must have movement. Otherwise, it would look like a ponding.

由于厚度为10-17厘米，水景长度接近100米，听起来是个不可能实现的目标。甚至整个水道都是一个斜坡。在没有任何缓冲区的情况下，它只有1%的坡度。这不仅仅是一个用设计可以解决的设计问题。团队与工程师、水务专家和客户合作，以提出最佳解决方案。溪流将分为3个部分，以缩短流动距离。他们的师是增援坦克所在的位置。这些技术要求被人行天桥所掩盖。两侧的每个进水口都升高以产生重力流，使水在溪流中更自然地移动。这些凸起的平台为创建水景提供了许多可能性。允许人们在这些区域进行愉悦的水上游乐活动。

With a 10-17 centimeters thickness allowance and almost 100 meters long water feature, it sounds impossible to achieve what we are aiming for. Even the entire water channel is a slope. It will be only 1% slope without any freeboard area. This is not only a design issue that can be solved by one design discipline. We have to work collaboratively with engineers, water specialists, and clients to come out with the best solution. The stream will be divided in 3 parts in order to shorten the flowing distance. Their divisions are where the surge tanks are located. These technical requirements are concealed by pedestrian bridges. Each water inlet on both sides is raised to create a gravity flow that would allow the water to move more naturally through the stream. These raised platforms provide many possibilities for water texture to be created. It allows active water play activities to happen in these areas.

溪谷增加了抛物线喷泉和汀步，为该地区增添了了趣味。与活跃的水流相比，中央水景设计为定向水流，与其他水流相比，流速要慢得多。这个区域变成了一个带有悬挂座椅的生活空间，人们可以坐在水面上放松休息。通过不同的水景设计解决方案完美创造了各种景观氛围。

Parabolic Fountain and field of stepping stone are added to create an interest for the area. In contrast with an active water stream, the central water feature is designed with one directional flow with much slower flow compared to the others. This area becomes a living space with hanging seats where people could sit and relax on the water. The various landscape atmospheres with different programs are created seamlessly with the different technical water design solutions.

溪谷步道位于一个狭窄阴凉但舒适的区域。引入水景作为主要设计特征。它不仅增强了舒适和轻松的氛围，而且在整个步行过程中创造了连续的空间流动。水幕创造了从地面到上方水平的视觉连接。有助于加速蒸发和冷却温度。另一个重要的垂直元素是树。在溪谷步道上，银橡树提供浅色阴影。它们有助于弱化建筑物的大规模体量，并使景观更加宜人。树木是改变Mega Foodwalk空间结构的重要装置。景观土丘的高度旨在营造舒适感，同时让空气流通。不能太高或太低。土丘顶部覆盖着各种地被植物。

Stream Valley Walk is located in a narrow shady but more cozy area. The water feature is introduced as a main design feature. It not only enhances the cozy and relaxing atmosphere, but also creates a continuous flow of space throughout the entire walk. Water curtains create a visual connection from ground level to the level above. It helps to create more evaporation that helps cool the temperature. Another important vertical element is the trees.On Stream Valley Walk, Silver Oak trees provide a light shade. They help to diminish the large scale of building massing and make the landscape more human scale. The trees are the great device that transforms the spatial structure of Mega Foodwalk. The height of landscape mounds have been designed for creating coziness and yet let air to flow to them. They must not be too high or too low. On top of the mounds, a mix of various groundcovers are sprinkled all over.

团队与软景承包商和植物苗圃密切合作，以确保能够找到可以用于场地的合适植物。地被植物经过精心挑选，为景观结构增色。地被植物勾勒出绿色岛屿和土丘的轮廓，景观土丘变得更清晰。这些地被设计增强了土丘的地形轮廓，以保留了更多水分，并为坐在它们附近的人创造了不同颜色的花朵和不同形状的叶子和纹理的新鲜感。地面上的景观看起来更加统一、形式感强烈，但又包含不同的细节。

We worked closely with softscape contractors and plant nursery to make sure that we could source the right mixture of planting that we could use. The groundcovers have been carefully selected in order to strengthen the form of landscape. Landscape mounds become more readable as groundcovers reveal the essential forms of the green islands and the field of dunes. These groundcovers design enhances topographic profile of the mounds, preserves more moistures, and creates the freshness feel from different colors of flower and different textures of leaf forms for people who are sitting close to them. The landscape on the ground looks more unified with strong form and yet contains different details within them.
