There is a real deficit in our culture's knowledge of overall landscape processes. I'm working hard to make sure that people get at least an exposure to the ways that different scales of process interact with each other.
One way this manifests is my first piece of advice in looking at an area of land - "walk down to the creek/river and get a sense of it's form." Oftentimes, I hear: "there is no river or creek" and this shows that they think the land ends at the property boundary. Everywhere is a watershed.
Uplands landscapes are shaped by water processes, and understanding the creek will help you understand what's going on upland. It's also a good idea to get a sense of the ridges- the roof of the watershed. Then walk over to the tops of the valleys.
Find the floodplains, which are supposed to be the areas that rivers flood, in order to release energy and drop sediment. A healthy river pours into a floodplain every couple years. Vegetation in the floodplain should support helping the water spread and soak.
If the river is incised- not allowed to leave it's channel- there is energy not being released during big events, and it will be expressed somehow: probably bad flooding elsewhere, but also further incision and the dropping of the river channel, which takes ground water with it.
A hungry river begins to meander or tear at it's sides, because it has to do something with all the extra energy. Rather than helping build soil like in a healthy flood event, it takes it away.
We can improve water infiltration & the holding capacity of the uplands above a flood plain, to soak & slow that water, to spread it's flow out through the year- so the river has less energy (to cause erosion). Vegetation, soils, meandering swales, ponds, well designed roads, can all move excess water into storage.
