Some beneficial functions of a floodplain are that when it floods, the water leaves behind a rich mixture of rock and soil which is called silt. Silt is very good to grow crops and plants in. Floodplains are usually filled with plants because of this.
The buildings would flood because if the river floods then the floodplain, a floodplain is flat land that is next to a river, made up of alluvium (sand, silt, and clay). When the river overflows, the floodplain is often under water,will/ would flood too, so if the land floods, then, the buildings and businesses on that land will flood too.
A floodplain is the land that is covered by water when a river overflows it's banks. When this happens, silt and clay are deposited over time and the land on either side of the river flattens out. Any depressions in the land will hold water when the river level returns to normal after flooding and therefore more clay and silt will be deposited there filling it up.
a delta is an area near a river's mouth where the water deposits fine soil called silt
A flood plain is a flat land bordering a river made up of alluvium (clay, sand and silt) deposited during floods. When a river overflows, the floodplain is covered with water. Hope this helps :)

The silt from the River Nile was exalent pfarming land, so people live in the flood pathof the Nile River, so they would be able to produce for food and trade for frequently.
They are formed by the gradually flooding and draining of a river. So, every time a river floods the silt it carries is depositied either sides of its banks, with eventually build up a flat layer of aluvinum, which is a flood plain.
Flat land near the edges of rivers formed by mud and silt deposited by floods is called a delta. There are several deltas around the world.
Topsoil, sand, silt, organic debris, and other assorted material.
Chemical weathering of rocks and other methods make silt.
