TL;DR: In this article, the authors measured denudation and erosion rates in Sri Lanka using cosmogenic nuclides in the steep, humid, tropical highlands of Sri Lanka.

TL;DR: In this article, the authors quantify the difference between the human-caused sediment yield and the natural rates of soil production and bedrock erosion in a now largely deforested tropical highland.

TL;DR: In this article, cosmogenic nuclide data on river sediment along a north-south transect across the southern escarpment reveal that the landscape is eroding ten times more rapidly in the escarpments zone (26 to 71 mm kyr(-1)) than in the high-elevation plateau above it and in the lowland plain beneath it.

TL;DR: In this article, a detailed investigation of the mineralogical, chemical, and Sr isotope compositions of samples within a regolith profile extending >10m from surface soil through the weathering front in charnockite bedrock (a high-grade metamorphic rock), corestones formed at the weather-ing front, as well as from the chemical composition of the dissolved loads in nearby streams was performed.

TL;DR: In this article, the authors report that the conservation measures adopted in the critical areas of the Upper Uma Oya have been very successful and had greatly contributed to the reduction of soil erosion.
