The Keller fountain in Portland, USA
IRA Keller waterscape square is the fountain square in front of the city hall of Portland. The plane of the waterscape square is like a square. The square is surrounded by roads. The front is south by East, facing the city hall building opposite the third street. In addition to the south side, the other three sides are surrounded by green space and rich trees.
The waterscape square is divided into three parts: source square, waterfall, large pool and central platform. The northernmost and highest source square is the source of flat and simple paving and waterscape. The paving elevation is basically the same as that of the road. The water flows to the water drop and waterfall of the square through the tortuous and widening waterway. The water drop is in broken line shape and staggered arrangement. The waterfall falls layer by layer, which is quite natural. After falling layer by layer, the water finally forms a very spectacular waterfall, pouring down and falling into the large pool.
