Streambank Erosion Susceptibility Index and Flood-prone Area Mapping along the Karra River, Hetauda, Central Nepal Sub-Himalaya

Quantifying sand provenance and erosion (Marsyandi River, Nepal Himalaya)

We use petrographic and mineralogical data on modern sediments to investigate erosion patterns in the Marsyandi basin of the central Himalaya, a privileged natural laboratory in which a series of multidisciplinary geomorphological, sedimentological, geochemical and geochronological studies have been recently carried out to unravel the interrelationships between tectonic, climatic and sedimentar...

Quantifying periglacial erosion in the Nepal high Himalaya

Quantifying erosion rates in high mountain environments is challenging because the erosional processes are often stochastic and catastrophic. Distinguishing between periglacial and glacial rates is especially challenging. In this study we focus on determining erosion rates from a glaciated alpine landscape where the bedrock sidewalls are eroding predominantly by blockfall.We utilize a topograph...

Landscape disequilibrium on 1000–10,000 year scales Marsyandi River, Nepal, central Himalaya

In an actively deforming orogen, maintenance of a topographic steady state requires that hillslope erosion, river incision, and rock uplift rates are balanced over timescales of 10–10 years. Over shorter times, < 10 years, hillslope erosion and bedrock river incision rates fluctuate with changes in climate. On 10-year timescales, the Marsyandi River in the central Nepal Himalaya has oscillated ...

Mountain Building, Erosion, and the Seismic Cycle in the Nepal Himalaya

The Himalaya is the most impressive example on earth of an active collisional orogen. It combines rapid crustal shortening and thickening, intense denudation driven by the monsoon climate, and frequent very large earthquakes along an incomparably long and high mountain arc. It has therefore been the focus of a variety of investigations that have addressed various aspects of mountain building on...
