Persian Gulf rain contributions, there is still a deficit of 416 cubic kilometers per year. This difference is supplied by currents at the Strait of Hormuz. The water from the Gulf has a higher salinity, and therefore exits from the bottom of the Strait, while ocean water with less salinity flows in through the top. Another study revealed the following numbers for water exchanges for the Gulf: evaporation = -1.84m/year, precipitation = 0.08m/year, inflow from the Strait = 33.66m/year, outflow from the Strait = -32.11m/year, and the balance is 0m/year.

Territorial disputes in the Persian Gulf boundary were not disclosed. More recently, a dispute over the Dolphin Gas Project has renewed interest in the 1974 agreement. Earlier, the physical separation of the southern portion of Oman from its territory on the Musandam Peninsula was a source of friction between Oman and the various neighboring emirates that became the UAE in 1971.
