Definition
Verb (intransitive): * To become blocked, filled, or choked with silt (fine sand, clay, or other material carried by running water and deposited as a sediment).
Usage

Examples

- The harbor silted up over decades, preventing large ships from entering.
- Environmental changes caused the lake to silt up more rapidly.
Advanced Usage
- The verb is often used in environmental science, geography, and engineering contexts to describe a problematic natural process.
- It can be used in both active and passive constructions (e.g., "The river silted up" / "The river was silted up by sediment from the deforested hills").
