The invention claimed is: 1. A flood prevention device comprising: a gate device constituting a passage between a flood prevention area and an outside area, and a portable flood prevention material that separates the flood prevention area and the outside area with the gate device, wherein the gate device has a side wall corresponding to one end of the portable flood prevention material; wherein the gate device has a watertight surface on the side wall, the watertight surface stopping water between the side wall and the portable flood prevention material; wherein the portable flood prevention material includes a tubular water bag; and wherein the gate device includes a joint hole on the side wall, the joint hole allowing insertion of one end of the tubular water bag and having an inner surface constituting the watertight surface for stopping water between the side wall and the tubular water bag. 2. A flood prevention device comprising: a gate device constituting a passage between a flood prevention area and an outside area, and a portable flood prevention material that separates the flood prevention area and the outside area with the gate device, wherein the gate device has a side wall corresponding to one end of the portable flood prevention material; wherein the gate device has a watertight surface on the side wall, the watertight surface stopping water between the side wall and the portable flood prevention material; wherein the portable flood prevention material includes a tubular water bag; and wherein the gate device includes a joint member having a joint hole on the side wall, the joint hole allowing insertion of one end of the tubular water bag, the joint hole having an inner surface constituting the watertight surface for stopping water between the side wall and the tubular water bag. 3. A flood prevention device comprising: a gate device constituting a passage between a flood prevention area and an outside area, and a portable flood prevention material that separates the flood prevention area and the outside area with the gate device, wherein the gate device has a side wall corresponding to one end of the portable flood prevention material; wherein the gate device has a watertight surface on the side wall, the watertight surface stopping water between the side wall and the portable flood prevention material; wherein the portable flood prevention material includes a tubular water bag; and wherein the tubular water bag has a water bag height larger than a height of a gate leaf of the gate device, the water bag height being 1.11 times to 1.67 times as large as the height of the gate leaf. 4. The flood prevention device according to claim 3 , wherein the gate device includes a watertight member on the side wall, the watertight member being connectable to or separable from a surface of the tubular water bag, the surface facing the outside area, the watertight member having the watertight surface for stopping water between the watertight member and the tubular water bag.
