at least one inlet pipe located on the dry side.
13. The floodwall shelter of claim 12 ,
wherein the at least one inlet pipe has a length, and
wherein at least a part of the length is perforated.
14. A method of installing at least one floodwall section, comprising:
excavating a site to an excavation depth of one foot or less to create an excavation site, wherein the excavating is at a location where the at least one floodwall section will be placed;
placing fill material into the excavated site;
applying a top layer to the fill material to create a flat surface; and
placing the at least one floodwall section on top of the top layer,
wherein the at least one floodwall section, once placed, is configured to resist flood waters without additional support structures;
wherein no portion of any floodwall section extends below ground;
wherein the at least one floodwall section comprises at least a first floodwall section and a second floodwall section, the first floodwall section and the second floodwall section each separately being one of the plurality of surface mounted floodwall sections of claim 1 ; and
wherein the first floodwall section and the second floodwall section are cast in a continuous pour on site.
15. The method of installing at least one floodwall section of claim 14 ,
wherein the top layer has a larger surface area than a bottom surface of the at least one floodwall section.
16. The method of installing at least one floodwall section of claim 14 , further comprising:
applying a seal to a wet side surface of the at least one floodwall section and the top layer.
17. The method of installing at least one floodwall section of claim 16 ,
wherein at least one floodwall section has a notch formed on the wet side surface, and
wherein applying the seal comprises filling the notch with the seal.
18. The method of installing at least one floodwall section of claim 14 ,
wherein the at least one floodwall section is one of the plurality of surface mounted floodwall sections of claim 1 .
