Abstract

This paper explores the factors scientists look at while collecting data for watersheds, and how these factors can serve as indicators of the health of a watershed. These factors may include: runoff, pollution, water cycle, erosion, and more.
Therefore, it is important to maintain the health of watersheds as they provide many benefits to humans, animals, and agriculture. We can do so by bringing attention to the challenge of protecting streams, and identifying the problems that watersheds go through which can then be repaired.

What Are Watersheds?
Despite the ever-widening ways humans are able to obtain and work with water, a watershed is a crucial part of sustaining life in more ways than one. A watershed is an area of

However, there are also many ways that a watershed can be deemed unhealthy. This can be due to the overwhelming factors of pollution that affects water quality. Some of the negative variables that scientists may study when collecting data on watersheds may include but are not limited to, runoff, pollution, erosion, and changes in water cycle that can affect flows in the river. Runoff is the movement of land water to the ocean and consists of precipitation that does not evaporate or go into the ground and is also a major cause to flooding. When land is paved or covered, the ground is not able to absorb water from the rain. The amount of water reduces due to human use which reduces the amount of fresh water available for the watershed. Factors that can be found in runoff include fine particles, fertilizers, pesticide and chemicals. These pollutants damage the watershed and the species that live in and visit the watershed.
Another variable that scientists may look into while studying watersheds is erosion. Soil being detached, carried away, and then eventually placed elsewhere results in erosion and can happen due to climate, soil characteristics, ground slope, vegetation, and more. This can be a big problem in watersheds because when the amount of soil increases, it can cause blockage in rocks and gravel beds, which are crucial for fish, insects, and other animals.
These are just a few of the variables that
