Self-filling erosion control apparatus

An erosion control apparatus, comprising:

• a flexible container comprising a container first end, a container second end opposite the container first end, a container first mouth toward the container first end, a container first funnel that couples the container first mouth to the container first end, a container second mouth toward the container second end, and a container second funnel that couples the container second mouth to the container second end;
• and
• a cord having a cord first end directly coupled to the container first mouth and a cord second end directly coupled to the container second mouth;
• wherein a length of the cord is shorter than a length of the flexible container between the container first end and the container second end;
• wherein the cord positions the container first mouth and the container second mouth between the container first end and the container second end due to the length of the cord being shorter than the length of the flexible container;
• wherein the container first funnel is configured to direct water and water-carried sediment through the container first mouth and into an interior of the flexible container;
• and
• wherein the flexible container is formed from a water permeable material that permits water to flow from the interior of the flexible container through the water permeable material while retaining water-carried sediment in the interior of the flexible container so as to permit collection of water-carried sediment in the flexible container.

An erosion control apparatus, comprising:

• a flexible container comprising:
• a flexible container first end;
• a flexible container second end opposite the flexible container first end, a flexible container top side that extends longitudinally from the flexible container first end to the flexible container second end;
• a flexible container bottom side that extends longitudinally from the flexible container first end to the flexible container second end;
• a flexible container first mouth toward the flexible container first end that provides an opening to an interior of the flexible container;
• and
• a flexible container first funnel that narrows from the flexible container first end to the flexible container first mouth and is configured to direct fluid and fluid-carried sediment through the flexible container first mouth and into the interior of the flexible container;
• and
• wherein multiple points of a lower funnel portion of the flexible container first funnel arranged longitudinally between the flexible container first end and the flexible container first mouth are secured to multiple points of the flexible container bottom side arranged longitudinally between the flexible container first end and the flexible container first mouth.
