摘要: Abstract Maximum mass transfer, in the Yamuna River takes place during monsoon season. The sediment load constitutes 58–86% of total carried by river depending upon sites. Tributaries are chemically more active than mainstream. seems to be controlled lithology. At Allahabad, carries 42 × 10 6 t dissolved chemical and 64 Ganges river. TSM/TDS ratio shows that upstream physical weathering is dominant weathering. negative relation between basin area erosion rate positive agreement with global trend. average (165 km −2 yr −1 ) much higher Indian average. (973 1.7 times greater Ganges. Upstream removes 1.04 mm surface; removal decreases downstream 0.19 at point confluence
