Gundia River
Gundia River is a second order tributary of the Netravathi river in the state of Karnataka in southern India. A proposal by the Government of Karnataka to build a hydroelectric project across the river and its tributary streams has generated controversy and opposition from environmentalists. River Basin The Gundia river is a tributary of the Kumaradhara river which in turn flows into the Netravathi. The Gundia's headstreams include the Yettinahole, Kerihole, Hongadahalla and Bettakumbri streams and the river basin straddles the districts of Dakshina Kannada and Hassan. Biodiversity The Gundia river basin is part of the Western Ghats and is extremely rich in biodiversity. There are 239 plant species in the area including 119 tree species across several vegetation types including tropical evergreen and semi-evergreen forests, moist deciduous forests, scrub jungles, grasslands and riparian vegetation. The Kaginahara and Kempahole Reserve Forests lie in the Gundia basin. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strahler Stream Order
In mathematics, the Strahler number or Horton–Strahler number of a mathematical tree is a numerical measure of its branching complexity. These numbers were first developed in hydrology, as a way of measuring the complexity of rivers and streams, by and . In this application, they are referred to as the Strahler stream order and are used to define stream size based on a hierarchy of tributaries. The same numbers also arise in the analysis of L-systems and of hierarchical biological structures such as (biological) trees and animal respiratory and circulatory systems, in register allocation for compilation of high-level programming languages and in the analysis of social networks. Definition All trees in this context are directed graphs, oriented from the root towards the leaves; in other words, they are arborescences. The degree of a node in a tree is just its number of children. One may assign a Strahler number to all nodes of a tree, in bottom-up order, as follows: *If the ...
