Answer:
Climate and River Flow, Erosion , River Obstructions, Pollution.
Step-by-step explanation:
Sediment movement contributes to deteriorating environmental factors by causing high turbidity which in turn limits sunlight penetration into the water column. This has a negative effect on the growth of algae and aquatic plants.
Sediments present in rivers with spawning organisms, disrupt the ecosystem because the gravel beds involved in spawning are covered with sediments. The habitat of the fish is therefore, destroyed through this movement process.
Sedimentation can also lead to increased flooding by blocking the effectiveness of the reroute that should occur with water into drainage channels. Flooding, disrupts processes such as water transportation, disrupts day to day living most notably in areas closest to these rivers. These sediments as well could disrupt irrigation by clogging hydraulic mechanisms set in place to provide irrigation.
