Manila, Monaco, Nottingham, Paris, Rotterdam, Singapore, Tianjin, and Toronto). The soothing qualities of a beach and the pleasant environment offered to the beachgoer are replicated in artificial beaches, such as "beach style" pools with zero-depth entry and wave pools that recreate the natural waves pounding upon a beach. In a zero-depth entry pool, the bottom surface slopes gradually from above water down to depth. Another approach involves so-called urban beaches, a form of public park becoming common in large cities. Urban beaches attempt to mimic natural beaches with fountains that imitate surf and mask city noises, and in some cases can be used as a play park. Beach nourishment involves pumping sand onto beaches to improve their health. Beach nourishment is common for major beach cities around the world; however the beaches that have been nourished can still appear quite natural and often many visitors are unaware of the works undertaken to support the health of the beach. Such beaches are often not recognized by consumers as artificial. A famous example of beach nourishment came with the replenishment of Waikīkī Beach in Honolulu, Hawaii, where sand from Manhattan Beach, California was transported via ship and barge throughout most of the 20th century in order to combat Waikiki's erosion problems. The Surfrider Foundation has debated the merits of artificial reefs with members torn between their desire to support natural coastal environments and opportunities to enhance the quality of surfing waves. Similar debates surround beach nourishment and snow cannon in sensitive environments. Restrictions on access Public access to beaches is restricted in some parts of the world. For example, most beaches on the Jersey Shore are restricted to people who can purchase beach tags. Many beaches in Indonesia, both private and public, require admission fees. Some beaches also restrict dogs for some periods of the year. Private beaches Private beaches may belong to owners of abutting land, or neighborhood associations. Signs are usually posted the entrance. A permit or special use occasion event may be granted upon executing the proper channels to legally obtain one. In some places, such as Florida, it is not always clear which parts of a beach are public or private.
