  • Drainage evolution of the lower Narmada valley, western India
  • Cenozoic ; Cretaceous ; Drainage network ; Fault ; Geomorphometry ; India ; Lithostratigraphy ; Madhya Pradesh ; Plate tectonics ; Tectonics ; Valley
  • Various tectonic disturbances from the Cretaceous to the present day have modified the geomorphic features of western India. Compression and extensional stresses generated by the northerly moving Indian plate, and its collision with the Eurasian
  • A mid-late Holocene flood record from the alluvial reach of the Mahi River, Western India
  • Alluvial plain ; Flood ; Holocene ; India ; Monsoon ; Palaeogeography ; Sedimentation ; Stratigraphy ; Stream
  • Flooding of rivers in India is linked with the peak monsoons. In this study, the slackwater deposits in the alluvial reaches of the Mahi river basin have been documented. These occur in the ravines incised during the early Holocene on an alluvial

  • Palaeoflood analysis of channel-fill deposits, central Tapti river basin, India
  • Channel geometry ; Flood ; Fluvial processes ; India ; Maharashtra ; Palaeohydrology ; Pedogenesis ; Sediment filling ; Sedimentary structure ; Watershed
  • The Quaternary sediments exposed on the banks of the river Aner which is a tributary of the river Tapti, near Piloda (district Dhule), western India, reveal 3 channel-fill structures, spatially at the same level. The AA. therefore present here
  • Morphological and hydrological characteristics of some allochtonous river channels, Western Deccan Trap Upland region, India
  • Relations are established between various channel morphologic variables for the Upland rivers of Western Deccan Trap region, using seventy-three sites, three channel categories and ten parameters. An attempt to relate morphologic variables
  • Slope failure and denudation in the western Himalaya
  • Catastrophe ; Flood ; Fluvial processes ; Glacial features ; Glaciation ; High mountain ; Himalaya ; India ; Mass movement ; Mountain ; Slope dynamics ; Soil erosion
  • This paper assesses denudation by mass-movement in the western Himalaya and relates the mobilization of debris by mass movement to further removal by glacial and fluvial processes.
  • Dendroclimatic reconstruction of april-may temperature fluctuations in the western Himalaya of India since A.D. 1698
  • Climatic variability ; Climatic variation ; Dendroclimatology ; Dendrology ; El Niño ; High mountain ; Himalaya ; India ; Monsoon ; Palaeoclimatology ; Palaeotemperature ; Spring ; UttarPradesh
  • The AA. present the reconstruction of mean April-May temperature variations back to A.D. 1698 using ring-width chronologies of Himalayan cedar, Himalayan pine, and Himalayan spruce from the western Himalaya. The most striking feature of the present
  • reconstruction is the absence of any warming trend in the 20th century. Relationships between the mean April-May temperature for the western Himalayan region, Indian summer monsoon rainfall, and Southern Oscillation Index indicate that the tree-ring chronologies
  • Shoulder uplift of the Western Ghats passive margin, India : a denudational model
  • Continental margin ; Dating ; Erosion surface ; Geophysics ; India ; Model ; Vertical movement
  • The paper presents a denudational rift flank uplift model of the Western Ghats of Karnataka. The Cenozoic denudation of the Deccan plateau was constrained by relative dating of regional planation surface levels, in combination with preliminary
  • apatite fission track results. The denudational history of the Western Ghats escarpment coastal foreland was constrained both by onshore fission track and offshore sediment data. Methods are briefly described. Results were used as reference data
  • All Toba tephra occurences across peninsular India belong to the 75,000 yr B.P. eruption
  • Dating ; Geochemistry ; India ; Pleistocene ; Quaternary ; Tephrochronology ; Trace-element ; Volcanic eruption
  • , allowing comparison of the Indian samples to those from the Toba caldera in northern Sumatra, Malaysia, and the sedimentary core at ODP Site 758 in the Indian Ocean. In addition, 2 samples of Toba tephra from western India were dated by fission-track method
  • A controversy currently exists regarding the number of Toba eruptive events represented in the tephra occurences across peninsular India. Resolution of this issue was sought through detailed geochemical analyses of a comprehensive suite of samples
  • . The results demonstrate that all the Toba tephra occurrences in peninsular India belong to the 75,000 yr B.P. Toba eruption.

  • The study area is located in the Pravara River Basin in the Western Deccan Province. Few previous studies postulated that badlands in the Western Deccan Upland Region owe their origin to the Pleistocene-Holocene climate change events. In order
  • local drop in the base-level, hence promoting erosion along these points to form the ravines. It is suggested that a neotectonic interpretation of apparently randomly spaced badlands development in the Western Deccan is more probable than a paleoclimatic
