A lawn sprinkler providing water distribution over an irregular or unique shaped water receiving area. The apparatus includes a water impeller, a first water regulator, a second water regulator, and a bypass channel. The sprinkler regulates the delivery of water according to the shape of the area to be irrigated, so that water is not wasted on adjacent areas which do not require irrigation.

1. A lawn sprinkler apparatus for regulating the flow of water, comprising: a base, said base configured to confiningly receive a pressurized water flow;a sprinkler nozzle assembly, said sprinkler nozzle assembly arcuately coupled to said base, and said sprinkler nozzle assembly comprising a nozzle, said sprinkler nozzle assembly responsive to said pressurized water flow to pop-up into an operating position for discharge of water from said nozzle;a drive mechanism coupled to said sprinkler nozzle assembly, said drive mechanism comprising a water driven impeller and a gear train adapted for operatively driving said sprinkler nozzle assembly via arcuate movement;a water flow regulator, said water flow regulator configured (a) for regulating a first portion of said water flow to increase water flow rate of said first portion of said water flow over said first unit of time, and for regulating said first portion of said water flow to decrease water flow rate of said first portion of said water flow over said second unit of time, and(b) for regulating a second portion of said water flow to decrease water flow rate of said second portion of said water flow over said first unit of time and to increase water flow rate of said second portion of said water flow over said second unit of time,said water flow regulator comprising a first inlet fluidically coupled to said base and a first outlet fluidically coupled to said nozzle, said drive mechanism fluidically driven by said first portion of said water flow;said nozzle sized and shaped (a) to decrease the radial length of water distribution along a first vector over said first unit of time in response to said decrease in water flow rate of said second portion of said water flow, and(b) to increase the radial length of water distribution along a second vector over said second unit of time in response to said increase in water flow rate of said second portion of said water flow; andsaid drive mechanism operative to increase said arcuate speed of said sprinkler nozzle assembly over said first unit of time in response to said increase in water flow rate of said first portion of said water flow, and to decrease said arcuate speed of said sprinkler nozzle assembly over said second unit of time in response to said decrease in water flow rate of said first portion of said water flow. 2. The apparatus as set forth in claim 1, wherein said water flow regulator comprises an impeller regulator portion and a nozzle regulator portion, wherein during said first unit of time, said impeller regulator portion is configured to operatively increase fluid flow through said impeller, and said nozzle regulator portion is configured to operatively decrease fluid flow through said nozzle, andduring a second unit of time, said impeller regulator portion is configured to operatively decrease said fluid flow through said impeller, and said nozzle regulator portion is configured to operatively increase fluid flow through said nozzle. 3. A method for watering a lawn, said method increasing the volume of water distributed along a first radial of first radial length using a rotating sprinkler nozzle assembly by decreasing angular speed of said sprinkler nozzle assembly over a first unit of time, anddecreasing the volume of water distributed along a second radial of second radial length using a rotating sprinkler nozzle assembly by increasing angular speed of said sprinkler nozzle assembly over a second unit of time,said method comprising:providing a base, said base configured to confiningly receive a pressurized water flow;providing a sprinkler nozzle assembly, the sprinkler nozzle assembly configured for pop-up operation with respect to said base upon receipt of said pressurized water flow, said sprinkler nozzle assembly rotatably driven with respect to said base, said sprinkler nozzle assembly comprising a sprinkler nozzle assembly housing and a nozzle;providing a drive mechanism coupled to said sprinkler nozzle assembly;rotatably driving said sprinkler nozzle assembly with said drive mechanism;regulating a first portion of said water flow with a water flow regulator to increase water flow rate of said first portion of said water flow over said first unit of time, and to decrease water flow rate of said first portion of said water flow over said second unit of time, said water flow regulator comprising a first inlet fluidically coupled to said base and a first outlet fluidically coupled to said nozzle, said water flow regulator further comprising an outlet fluidically coupled to said drive mechanism, said drive mechanism fluidically driven by said first portion of said first flow;regulating a second portion of said water flow with said water flow regulator to decrease water flow rate of said second portion of said water flow over said first unit of time and to increase water flow rate of said second portion of said water flow over said second unit of time;wherein said nozzle decreases radial length of water distribution of along a first vector from said axis over said first unit of time in response to said decrease in water flow rate of said second portion of said water flow, and increases radial length of water distribution along a second vector from said axis over said second unit of time in response to said increase in water flow rate of said second portion of said water flow; andwherein said drive mechanism decreases said angular speed of said sprinkler nozzle assembly over said second unit of time in response to said decrease in water flow rate of said first portion of said water flow, and increases said angular speed of said sprinkler nozzle assembly over said first unit of time in response to said increase in water flow rate of said first portion of said water flow. 4. The method as set forth in claim 3, wherein said law comprises a plurality of portions, and wherein said method further comprises application of a substantially uniform volume of water to various portions of said lawn, on a per square foot of lawn basis. 5. The method as set forth in claim 3, wherein said law comprises a plurality of portions, and wherein said method further comprises application of a substantially uniform volume of water to all portions of said lawn, on a per square foot of lawn basis. 6. The method as set forth in claim 3, wherein said lawn has a perimeter of irregular shape. 7. The method as set forth in claim 6, wherein said method comprises substantially avoiding delivery of water beyond said perimeter of said lawn. 8. The method as set forth in claim 3, wherein said lawn has a perimeter of non-circular shape. 9. The method as set forth in claim 8, wherein said method comprises substantially avoiding delivery of water beyond said perimeter of said lawn. 10. The method as set forth in claim 3, further comprising providing said water flow regulator using a first perforated disc and a second perforated disc mounted for rotary movement with respect to each other, to cooperatively provide for maintaining, or increasing, or decreasing water flow through said water flow regulator during movement of the second perforated disk relative to the first perforated disc. 11. The method as set forth in claim 3, wherein said lawn comprises portions, and wherein variance of angular speed of said nozzle assembly while increasing volume or decreasing volume of the first portion of water flow or of the second portion of water flow provides a substantially uniform volume of water to each of said portions.
