A pouch (18), made of a water absorbent polymer that expands and becomes a gel in consistency upon absorbing water and that is biodegradable, is placed in each bag (10) of lesser volume. An opening (12) in each bag (10) is unsealed to drain the bags (10) of the biodegradable gel, as by squeezing the bag (10) to force the gel from the bag (10). The collapsed bags (10) can be re-stored for future use and the gel biodegraded as by disposition the conventional sewage system.

1. A method of forming a water baffler comprising the steps of: storing a plurality of bags (10) each made of water impervious material and including a sealable opening (12), storing a plurality of pouches (18) of a water absorbent polymer that expands and becomes a gel in consistency upon absor

1. A method of forming a water baffler comprising the steps of: storing a plurality of bags (10) each made of water impervious material and including a sealable opening (12), storing a plurality of pouches (18) of a water absorbent polymer that expands and becomes a gel in consistency upon absorbing water and that is biodegradable with each pouch (18) having less volume than the maximum volume of each bag (10), placing the polymer of at least one of the pouches (18) in each bag (10), filling each bag (10) with a predetermined amount of water to expand each bag (10) as the polymer expands into a gel expanding the volume of each bag (10), sealing the opening (12) in each bag (10) to prevent egress of the gel from the bag (10), stacking the bags (10) to form a water baffler, unstacking the bags (10), unsealing the opening (12) in each bag (10), flowing the gel from each bag (10), collapsing each bag (10), biodegrading the gel, re-storing the collapsed bags (10) for re-use. 2. A method as set forth in claim 1 including placing a pouch having the polymer surrounded by a pervious container (20) and bursting the container (20) as the polymer expands. 3. A method of providing a water barrier system comprising the steps of: providing a plurality of bags (10) each made of water impervious material and including a sealable opening (12); and providing a plurality of pouches (18) of a water absorbent polymer that expands and becomes a flowable gel in consistency upon absorbing water and that is biodegradable with the polymer of each pouch (18) having less volume than the maximum volume of each bag (10); further including the step of placing the polymer of one of the pouches (18) in each bag (10). 4. A method as set forth in claim 3 including the steps of: filling each bag (10) with water to expand the bag (10) as the polymer expands into a gel expanding the volume of each bag (10), sealing the opening (12) in each bag (10) to prevent egress of the gel from the bag (10), and stacking the bags (10) to form a water barrier. 5. A method as set forth in claim 4 including the steps of; unstacking the bags (10), unsealing the opening (12) in each bag (10), flowing the gel from each bag (10), biodegrading the gel. 6. A method as set forth in claim 3, wherein each pouch (18) includes a pervious container (20) surrounding the polymer, further including the steps of expanding the polymer in the container and bursting the pervious container in the bag as the polymer expands.
