The valley of Ankhu Khola is located between Ganesh Himal to the north, Tiru Danda to the east and Abuthum Lekh in the west in an area to the northwest of Kathmandu. The area was found to be of interest due to the multiplicity of ecological problems and its apparent remoteness in spite of its close proximity to Kathmandu. The author has been involved in running a series of surveys in the area...
Till 1950 no substantial geological studies could be made in the kingdom of Nepal. The first geological study of Nepal Siwaliks was made by Auden (1935) and then Lombart (1952) and in 1959, Toni Hagen minutely studied the cross-sections of the Siwaliks and noted three-fold stratigraphic division in its formation.
This paper analyses the studies and the findings of geological studies in...
In this comprehensive and abundantly illustrated book, Allan Schoenherr describes a state with a greater range of landforms, a greater variety of habitats, and more kinds of plants and animals than any area of equivalent size in all of North America. A Natural History of California will familiarise the reader with the climate, rocks, soil, plants and animals in each distinctive region of the...
Aimed at 4 to 8 year olds, this book's colour photographs capture young readers' attention, with clear text and well-designed diagrams. There is a profile of the world's major peaks, allowing for a visual comparison of heights. More information about the major ranges is provided as the different types of mountain formations are considered. Simon also covers their...
America's Mountains thoroughly explains the geological origins and history of North America's magnificent mountains. The book begins with an exploration of orogeny, the process of mountain formation. Subsequent chapters investigate the dramatic influence of these land masses on plants, animals, people, and the general environment.
The concept of physiography integrates all of the main components of the natural environment, such as bedrock, surface drift deposits, landform, soils, climate, water, and plants and animals. This paper summarises the provisional physiographic zonation of Bhutan, based on soil survey fieldwork by the National Soil Services Centre, with some material incorporated from other environmental...
Geothermal energy is the energy contained in the heated rock and fluid that fills the fractures and pores within the earth's crust. It originates from radioactive decay deep within the Earth and can exist as hot water, steam, or hot dry rocks.
Mountainous soil erosion processes were investigated in the Urseren Valley (Central Switzerland) by means of measurements and simulations. The quantification of soil erosion was performed on hill slope scale (2·20 m) for three different land use types: hayfields, pastures with dwarf shrubs and pastures without dwarf shrubs with three replicates each. Erosion...
Reliably relocated earthquake hypocenters in the Pamir-Hindu Kush region for about 1700 earthquakes deeper than 50 km, are examined using 3-D color plots. The hypocenters define an single contorted “S” shaped seismic zone, 700 km long and no more than 30 km wide and with most activity concentrated in the 100-300 km depth range.
The crustal structure of the Himalayan fold-thrust belt in NW Himalaya is constrained using spectral analysis, wavelet transform (WT) and forward modeling of the Bouguer gravity anomaly. The data covers the Himalayan range from the Sub Himalayan zone in the hanging wall of Himalayan Frontal Thrust (HFT) to the Karakoram fault across the Indus Tsangpo Suture Zone (ITSZ), along about 450 km long...
