canal with murky, grey water flowing downstream

canal with murky, grey water flowing downstream. The canal is flanked by concrete embankments. On the left side, there are several large, empty, beige planters. On the right side, the embankment transitions into a natural bank with some small bushes growing. A row of buildings is visible in the background, including a yellow apartment building. Several cars are parked along the bank near the buildings. The sky is overcast, and the overall lighting is subdued.
