3. INTRODUCTION A stream is a naturally occurring flow of water that follows a temporary or sometimes permanent path, beginning from some elevated area and flowing downwards towards a specific direction or larger water body, due to gravity. Stream hazards are the potential dangers or risks associated with flowing water bodies depending on weather conditions, human activities, and the geography of the areas, Which may include fallen trees

4. HAZARDS POSED BY STREAMS ON THE ENVIRONMENT Flooding: Floods are natural occurrences that occur when water from streams overflow onto dry land and submerge it. This occurs due to water levels rising over what the regular stream channel can hold due to intense or prolonged rainfall events, leading to habitat destruction for both aquatic organisms and land organisms. Floodplains are the regions that are subject to flooding.

5. Water erosion: This is the removal of soil by water, transporting it away from the point of removal As water flows from its source to its mouth on a stream, it carries soil from the higher elevated areas to areas of low elevation. This is a slow but continuous process, which then leads to water erosion.

6. Disruption in nutrient cycling: This is the removal of soil by water, transporting it away from the point of removal as water flows from one region to another, soil is being carried away. This can be a fast process sometimes, when streams are fast flowing, they may carry away soil that contains nutrients such as nitrogen and phosphorus which are important for aquatic life to thrive.

7. HAZARDS POSED BY STREAMS ON SWIMMERS AND BOATERS Fast-flowing and strong currents: Swimmers and boaters can be swept away by fast-flowing currents. Strong currents make it difficult for boats to navigate the area, while strong undercurrents are capable of pulling swimmers and boaters in. Submerged objects : These include trees, rocks, and debris that may not be visible on the surface of the streams and can lead to boats easily colliding with them. These objects can also be fatal to those who may fall into the streams.

8. Cold water temperatures : Even in warmer climates, streams can be cold, especially in regions with cold climates. Immersion in these cold-water can lead to individuals developing hypothermia which is a condition that causes the body to lose so much heat that it is unable to warm itself up.

9. Conclusion Stream hazards pose a significant number of threats to the environments that surround it, as well as to the aquatic life in it. This involves flooding which destroys both aquatic and land habitats, disrupting the nutrient cycle in water, and water erosion, among many more stream hazards. To reduce and or avoid these potential dangers posed by streams, it is important to make people and boaters aware of them to take appropriate action against them .
