evidence: There are a number of countries on this list that do not have rivers due to their climate. Nations that are primarily desert, or which have particularly arid climates, tend not to have rivers, or are unable to sustain permanent rivers year round. Of these, Saudi Arabia is by far the largest in terms of area. Since Saudi Arabia is a sandy, dry and hot place, it is simply too arid and too warm for much rainfall, and that which does land, is immediately absorbed or evaporated in the heat. No rivers or major bodies of water exist here, aside from Oases, which do pop up across the desert sand dunes. Through these, and desalination plants which remove salt from saline water sources, the country has been able to sustain its population. [...] Other such desert or dry climate countries without rivers include Kuwait, Oman, Qatar, the United Arab Emirate, and Yemen. In addition to these, Djibouti has no proper rivers, due mainly to its climate, and only has intermittent, seasonal small creeks which run through the mountains during the rainy seasons.
