Natural watersheds are naturally occurring pathways that leads rain water or snow into the lakes/streams/dams. the land topography determines the direction and velocity of the water flow. In natural occurring watersheds there is little to no nutrient loss
Clear cutting is the process of cutting down trees in a specific area. The removal of all trees exposes causes a number of problems such as soil erosion, washing away of nutrients due to the lack of trees that normally hold the water, and increased stream flow.
A watershed is a region obtaining both land and water. This is a shallow land region which accumulates water from drainage obtain from different sources like lake, river and pond. A watershed may also develop in a forest ecosystem. The clear cutting of forest will result expose more amount of soil nutrients for erosion by water as compared to natural forest. Therefore, nutrient loss will be higher in clear- cut watershed than natural forest watershed.
