Himalayan valley sizes are controlled by tectonic-driven rock uplift, study shows

The oceans are the final destination of weathering products from the land and its transport via rivers, with those in the Himalayan mountains alone moving one billion tons of sediment each year. To understand the storage dynamics of mountain valley systems, it is important to determine the spatial distribution of rivers, their volumes and longevity on seasonal and longer-term timescales. This is especially true given erosion processes widen valleys and therefore expand the spatial distribution of sediment influxes to oceans.
