Ganges Basin (112,490 km²), West Bengal (71,485 km²), Haryana (34,341 km²), Himachal Pradesh (4,317 km²) , Delhi, Arunachal pradesh(1,484 km²), the whole of Bangladesh, Nepal and Bhutan. Several tributaries rise inside Tibet before flowing south through Nepal. The basin has a population of more than 500 million, making it the most populated river basin in the world. The basin comprises semi-arid valleys in the rain shadow north of the Himalaya, densely forested mountains south of the highest ranges, the scrubby Shiwalik foothills and the fertile Gangetic Plains. Central highlands south of the Gangetic Plain have plateaus, hills and mountains intersected by valleys
Yukon River Basin streams, and lakes. There are also many different types of soils that make up the Yukon River Basin. These soils include Entisols, Gelisols, Inceptisols, Inceptisols/Gelisols, Mollisols, Spodosols, and Rough Mountainous Land. Permafrost dominates the Yukon River Basin. Because of the excessive level of permafrost in the basin, the basin itself is far more prone to flash floods. The melting of permafrost is believed to be one of the reasons that the Yukon River Basin's flow has increased over the years, causing erosion of the basin. The Yukon River Basin drains from east to west, with the temperature of the water
