Claim 13:
14. An erosion control apparatus, comprising:
a flexible container comprising:
a container upper side having an upper leading end and an upper trailing end opposite the upper leading end;
a container lower side opposite the container upper side, the container lower side having a lower leading end and a lower trailing end opposite the lower leading end;
a container mouth between the upper leading end and the lower leading end of the flexible container, wherein the container mouth provides an opening to a container interior; and

a cord attached between the container mouth and an attachment point toward the upper trailing end of the flexible container,
wherein the cord draws the container mouth toward the upper trailing end due to a length of the cord between the container mouth and the attachment point being shorter than a length of the flexible container between the upper leading end of the flexible container and the attachment point;
wherein the cord draws the container mouth toward a closed position as sediment enters the container mouth, fills the container interior, and urges the container mouth away from the attachment point;
wherein a leading end of the container mouth comprises a sequence of holes that circumscribe the container mouth; and
wherein the cord forms a noose in which a loop of the noose is threaded through the sequence of holes and circumscribes the container mouth.
