Delta

Real World Example

Imagine you're cleaning out your closet, and all the items you no longer need start piling up at the entrance of your room. This clutter at the doorway is similar to how a river deposits sediment at its mouth, forming a delta. Just as unwanted items accumulate at the threshold because they have nowhere else to go, sediment carried by a river gathers at its mouth, creating a buildup as the water slows down and deposits its load.
