A study was conducted to estimate the rate of solid and dissolved mass denudation from six prominent landuse systems of Bhetagad micro watershed, Gomti basin of Indian Central Himalaya. An investigation was also conducted to assess the seasonal variation in water quality parameters influenced by rainwater in the four sub-catchments of Gomti basin.

Elevated arsenic in groundwater is the greatest environmental problem in Bangladesh. Spatial variability of arsenic in groundwater has been examined by semivariogram analysis that revealed high degree of small-scale spatial variability in alluvial aquifers. Small-scale variability of arsenic concentrations, indicated by high "nugget' values in semivariograms, is associated with heterogeneity in local-scale geology and geochemical processes. In unsampled locations, arsenic concentrations have been predicted using both deterministic and stochastic prediction methods.

The Kathmandu reaches of the Bagmati River are widely characterised as severely degraded. This article explores the rhetorical life and death of the concept of a 'Bagmati civilisation': a particular configuration of history, cultural identity and river ecology espoused by a prominent Nepali river restorationist.
