   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to portable and/or quickly constructed levees. More particularly, the present invention relates to a levee apparatus that employs base panels and inclined panels that interlock to provide a generally triangular cross section with an interior that can be filled with a selected fill material (e.g. soil, sand, gravel, etc.), wherein alternating projections and sockets/apertures along edges of the panels interlock to form a connection of each panel to other of the panels. 
   2. General Background of the Invention 
   Levees are often constructed of earthen material. In some locations the side of an earthen levee is lined with concrete. The U.S. Army Corps of Engineers has for years constructed earthen levees with a portion of a side of the levee being covered with a layer of reinforced concrete. At the U.S. Army Corps of Engineers facility at Vicksburg, Miss., concrete levee mats have been fabricated for years. 
   Portable levee systems have been patented as noted in the following table of possibly related art. 
   The following U.S. Patents are incorporated herein by reference:

   DETAILED DESCRIPTION OF THE INVENTION 
     FIGS. 1-8  and  13  show the preferred embodiment of the apparatus of the present invention, designated generally by the numeral  10  in  FIGS. 6-8 . Levee apparatus  10  provides a base panel  12  that interlocks with a pair of inclined side panels  29 . Base panels  12  are place end-to-end. Side panels  29  are then connected to the base panels  12 . Side panels  29  are connected to each other at apex  66 . The panel  12  and the inclined side panels  29  are connected in a staggered, brick lay type pattern as shown in  FIGS. 5-8  and  13 . Once connected together, the panels  12 ,  13  form a generally triangular cross section (see  FIG. 7 ). 
   In  FIGS. 1-2 , a side panel  29  is shown in more detail. Side panel  29  has end edges  30 ,  31 , upper surface  44 , lower surface  45 , upper edge  49  and lower edge  50 . Side panel  29  has projections  32  that are spaced apart along upper edge  49 . A gap  33  is placed between each pair of projections  32 . 
   At end edge  31 , there is a notch  34  near upper edge  49  and a notch  35  next to lower edge  50 . Similarly, there are projections  36  and gaps  37  along lower edge  50 . A beveled or inclined surface  40  is provided next to each gap  37 . These surfaces  40  are bearing surfaces that bear against contact area  43  on the upper surface  20  of base panel  12 . Surfaces  40 ,  41 ,  42  surround each gap  37 . Each gap  33  can be generally rectangular in shape, surrounded by three surfaces that are normal to both the upper  44  and the lower  45  surfaces of side panel  29 . Projections  38 ,  39  are next to end edge  30 . Each projection  38 ,  39  can share an edge with end edge  30  as shown in  FIG. 1 . 
   Base panel  12  is shown in more detail in  FIGS. 3 and 4 . Base panel  12  has end edges  13 ,  14  and side edges  15 ,  16 . A plurality of apertures  17  are provided along each edge  15 ,  16  as shown in  FIGS. 3-4 . Each aperture  17  extends through panel  12 , communicating with upper surface  20  and lower surface  21  as shown in  FIGS. 3-4 . 
   Notches  18 ,  19  are provided on panel  12 . Notch  18  is positioned next to the side edge  15  and communicating with the end edge  13 . Notch  19  is positioned next to the side edge  16  and communicating with the end edge  14 . 
   Each aperture  17  is bordered by a beveled or inclined surface  22  that forms an acute angle with panel  12  lower surface  21  as shown in  FIGS. 3-4 . Each aperture  17  is also surrounded by or bordered by surfaces  23 ,  24 ,  25  that are surfaces preferably normal to surfaces  20 ,  21 . Each notch  18 ,  19  is surrounded by or bordered by surfaces  26  (beveled or inclined),  27 ,  28 . A contact or load transfer area  43  on base panel  12  is engaged and contacted by a diagonally extending or beveled surface  40  of a side panel  29  as shown in  FIGS. 1-5  and  13 . Each base panel  12  and side panel  29  can be reinforced with reinforcing steel  71  or any other suitable reinforcement. 
   To erect levee apparatus  10 , base panels  12  are placed end-to-end as shown in  FIGS. 5 and 6 . The end edge  13  of one base panel  12  is place next to and aligned with the end edge  14  of another base panel  12 . Side panels  29  can be attached to base panels  12  in an alternating, brick layered type pattern of  FIGS. 5-6  and  13  (see arrows  46 ,  67 ). Each side panel  29  thus preferably attaches to a pair of base panels  12  as well as to a pair of side panels  29  at apex  66  (see  FIG. 7 ). 
   Bolted connections  52  can be used to affix each pair of side panels to support  47  as shown in  FIG. 7 . Each bolted connection  52  can employ a bolt or fastener  53  that engages an internally threaded opening  54  in support panel  47 . An opening  55  is a bolt opening that enables each fastener to pass through a panel  29 . 
   An air space  56  is provided below the erected side panels  29  as shown in  FIG. 7 . Fill opening  57  enables a selected fill material  59  (e.g. sand, soil, gravel) that is suitable for the construction of levees to be added to space  56 . Cap or cover  58  seals or covers fill opening  57  before and after filling space  56  with fill material  59 . 
     FIGS. 9-11  show an alternate levee apparatus  11  that uses a plurality of inclined panels  63  secured to a water bed  61  that is under a water body  60 . Piling  62 , triangular panels  63  and fill material  65  hold panels  63  in an inclined position. In various embodiments the angle of inclination can be about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 89, and 90 degrees with the water bed  61 . In various embodiments the angle of inclination can be in a range of between about any two of the above referenced angles. 
   Once piling  62 , panels  63 ,  64  and fill material  65  have been erected, levee apparatus  10  ( FIGS. 1-8  and  12 - 13 ) can be erected upon fill material  65  as shown in  FIG. 11 . 
   Arrows  68  in  FIG. 11  show water flow over levee  11  during a storm surge. Water flows over levee  11  carrying accretions  69  that accumulate to form a new land mass that supports plant life  70  for replenishment of wetlands that have eroded. 
     FIG. 12  illustrates that side panels  29  can be erected and interlocked at apex  77  and held in position using piling  62  rather than base panel  12 . In  FIG. 12 , the side panels  29  would be interlocked and brick layed staggered fashion as with the embodiment of  FIGS. 1-11 . However, pilings  62  support two panels  29  in an inclined position forming a generally triangularly shaped levee which can be back filled with a selected fill material such as sand, gravel, soil, or the like. In  FIG. 12 , notice that the side panels  29  can be of differing sizes to accommodate changes in elevation of water bottom  61 . 
     FIGS. 14 and 15  show an additional alternate embodiment of the apparatus of the present invention designated generally by the numeral  72 . Levee apparatus  72  is comprised of a plurality of sections  73 ,  74 ,  75  and possibly additional sections that are connected end to end as shown in  FIG. 14 . Each section provides a first end portion  76  that interlocks with a second end portion  77 . The end portion  76  provides a socket  78  that is receptive of an end portion  77  of another section as shown in  FIG. 15 . A stop  79  limits the amount of penetration of end portion  76  into socket  78  as shown in  FIG. 15 . 
   Each section  73 ,  74 ,  75  can provide an opening  80  that can be closed using a cap  81 . Opening  80  and cap  81  enable fill material such as sand, gravel, soil, or other suitable fill material to be added to the interior  82  of each section  73 ,  74 ,  75 . The levee apparatus  72  shown in  FIGS. 14 and 15  could be employed in situations such as those shown and described with respect to  FIGS. 1-13 . 
   As an alternative to the sections  73 ,  74 ,  75  shown in  FIGS. 14 and 15 , similarly connecting interlocking sections could be provided wherein each section has a gradual taper along its length. An end portion of each section is of a slightly larger, generally triangular cross section. The other end portion of that section is of a smaller, generally triangular cross section. In such a case, an end portion of one such tapered section fits into the end portion of another such tapered section. In this embodiment a section can be pulled longitudinally from a mold for forming the panel. Alternatively, the mold can be made in interlocking sections which lock when section is poured and cured, and unlock after section has cured. 
   In one alternative embodiment can be included a variation of the embodiment shown in  FIGS. 9 through 11 . In this embodiment the upper portion of the levee barrier (panels  29 ) does not span from edge to edge of the lower portion of the barrier (panels  63 )—as shown in  FIGS. 10 and 11 . Instead, a smaller portion (with spaced apart edges) compared to the larger lower portion is used. In various embodiments the upper portion can span about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, and 95 percent of the width of the upper part of the lower portion. In various embodiments the spanning percentage can be in a range of between about any two of the above referenced percentages.

Summary:
A levee apparatus is constructed of base panels connected end to end and supported by an underlying support such as the earth&#39;s surface. Side panels interlock with the base panels and with each other to form a generally triangular transverse cross section and a hollow interior that can be filled with a selected fill material. Interlocking projections on the side panels interlock with apertures of the base and with notches or recesses of other side panels.
