What is a karst floodplain?
Normally, rivers flood by periodically overflowing their banks. As water spreads out, its velocity slows and sediment load drops out and is deposited. The receding flood deposits very rich soil on this bottomland, gained at the expense of upstream farmers. If the stream banks originally contained sinkholes, they will open again, sometimes quickly. The Sharp Farm is located on a flat, shallow karst floodplain in the valley bottom.
