Kabani river is a 7 order stream with a basin area of 1647 km. There are 4 sixth order and11 fifth order sub-basins. This analysis is mainly confined to 11 fifth order sub basins. Morphometric indices like stream ordering, bifurcation ratio, stream length, drainage density, stream frequency, form factor, elongation ratio, circularity ratio, constant of channel maintenance, asymmetry factor, sin...

prioritization of sub-watersheds is very important in the natural sources and watershed management. in this study, the morphometric parameter and landuse changes using rs and gis techniques used in order to identify erosion-prone sub-watersheds. the morphometric parameter such as basin relief, the linear parameters (drainage density, bifurcation ratio, length of overland flow, stream frequency ...

Catchment morphology and drainage density are strongly influenced by hillslope processes. The consequences of several different hillslope process laws are explored in a series of experiments with a numerical model of drainage basin evolution. Five different models are considered , including a simple diffusive-advective process transition, a runoff-generation threshold, an erosion threshold, and...

The main basin for breast lymphatic drainage is ipsilateral axilla. However, extra-axillary drainage may be seen in some patients. The most common extra-axillary site is internal mammary chain, while contralateral axillary drainage is an extremely rare situation in previously untreated patients. We describe a case of untreated right breast retroareolar carcinoma with contralateral axillary drai...

Lundin, L. 1994. Impacts of forest drainage on flow regime. Studia Forestalia Suecica 192. 22 pp. ISSN 0039-3150, ISBN 91-576-4872-7. High floods in watercourses are of great interest. because of the potential hazards they pose to people and low-lying land near rivers. In many parts of the world, inundations are common and in northwest Europe there are high discharges almost every year, occasio...

This interdisciplinary paper reports the results of a study into the costs and benefits of eutrophication reduction in the Baltic Sea. A large multidisciplinary team of natural and social scientists estimated nutrient loadings and pathways within the entire Baltic drainage basin, together with the costs of a range of abatement options and strategies. The abatement cost results were compared wit...
