In Texas law, what primarily characterizes alluvium?

Alluvium is characterized primarily as added land formed by natural processes, specifically through the deposition of sediment by flowing water. In Texas law, alluvial deposits are areas where soil, sediment, or materials are transported by a river and subsequently deposited, increasing the land area. This process plays a critical role in river dynamics and can create new land adjacent to riverbanks over time.

Understanding the formation of alluvium helps in recognizing its significance in natural resource management and property rights. This added land can contribute to property boundaries, ownership issues, and land use considerations.

The other options do not capture the essence of alluvium. It is not strictly related to selling land to developers, and while land can be affected by flooding, alluvial land is formed from such processes rather than being deemed unusable. Additionally, alluvium typically has property claims, contrary to the suggestion of having no ownership claims. Thus, the primary characteristic that stands out based on Texas law is the natural formation of added land through depositional processes.
