Models for river avulsions have identified the ratio between down-valley and cross-valley slopes of channels as the triggering factors for the sudden channel shift but have remained untested in the field. The August 2008 avulsion of the Kosi River at Kusaha, 12 km upstream of the Kosi barrage in Nepal, provided an opportunity to study a large-scale avulsion (~120 km) for its causal factors and driving mechanisms.

In attempting an understanding, this article seeks to step outside the conventional nationalist mode of geopolitical analysis.

Geochemical study of a 3.55 m long lake sediment core from the Badanital Lake (Garhwal Himalaya) reveals Late Holocene centennial-scale climatic changes. The ecosystem of the tectonically formed lake seems to be controlled by natural and anthropogenic factors.
