Kangaroos do not live in dry river beds.
Australia is criss-crossed by both permanent / semi-permanent rivers and creeks, and dry river or creek beds. Kangaroos do not inhabit dry watercourses, as they need fresh food and a source of water to drink. However, because of the prevalence of both kangaroos and dry watercourses, it may be perceived that kangaroos sometimes live in these watercourses. This is especially the case since they will feed on any vegetation they may find in the watercourse, as such vegetation is usually there because of the sub-surface moisture.

Mars is known to have dry river beds, which are evidence of past water flow on the planet. These ancient river channels suggest that liquid water may have once existed on the Martian surface.
You might be thinking of "arroyos", Spanish for "dry river beds".
The Ord's Kangaroo rat lives mainly on seeds, as well as plant parts and insects. It finds its food in the dry regions where it lives, in the vegetation that inhabits these regions.

It was generally found in the dry lake beds that had been left as a result of hydration and then recession of the water in the Nile Valley.The simple answer is "dried up lake beds."
Well, it depends on what you mean by "old". The Appalachian Mountains and all their ranges are billions of years old. The Rocky Mountains are also billions of years old, but younger than The Appalachian Mountains. Both mountain ranges have "old river valleys" and very deep river gorges. The west has more dry river beds until there are floods; the eastern river beds are typically running year round with water.
Dry steam beds in the desert are known as arroyos. These are usually dry channels formed by intermittent water flow in arid regions, which can fill with water during flash floods. Arroyos play a significant role in shaping desert landscapes and ecosystems.
