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.

Beginning in the 20th century, the British Empire sought to strengthen its connections to British-controlled India which in turn resulted in a greater interest in the Persian Gulf region, culminating in the visit of the Viceroy of India Lord Curzon to the Gulf in 1903. To ensure that British agents in the region were adequately informed and prepared to strengthen their influence in the region, a light-weight and easily accessible handbook was needed. In November 1903, the British authorities commissioned John Gordon Lorimer, a member of the Indian
