Insight Into

Watershed based interventions are essential for the sustainable land and water management of any region. Watershed prioritisation is a must for the efficient utilisation of available monetary and human resources. One of the most common means of prioritisation is through morphometric analysis as hydrological processes or watershed responses depend on morphometric characteristics of the watersheds. The study contains morphometric analysis of a few number of micro watersheds of river Bharathapuzha of Kerala state. With the help of ArcGIS software and SRTM DEM, all the basic morphometric characteristics and derived morphometric characteristics of 10 micro watersheds are determined and then scores are assigned to the parameters. Finally, combined parameter scores are determined and ranking of each micro watershed is done. The priority scores between watersheds show considerable variation which is an indication of the efficacy of the methods employed. Once the ranking of the micro watersheds are done objectively and scientifically it would be a great support to the soil and water conservationist and planners. This study gives an insight into the applicability of the method to a mid land region in the state of Kerala, India.

Limited natural resources and their wide utilization with increasing population is a major concern. Conservation of natural resources is of prime importance for sustainable development and to mitigate the demand and supply gap between resources. Rivers are major source of water, Morphometric analysis of watershed covers the drainage networks and parameters such as drainage area, gradient and relief. Morphometric analysis is significant for prediction of floods, soil erosion and sediment yields. Present study covers linear aspects of Morphometric analysis in Bisalpur Reservoir by using Geospatial techniques. Watershed delineation, flow accumulation, flow direction, Flow length followed by Stream ordering have been accomplished by using Hydrology tool in ArcGIS 10.2.2 Software. Advanced space-borne Thermal Emission and Reflection Radiometer (ASTER) and Shuttle Radar Topographic Mission (SRTM) Digital Elevation model (DEM) have been used for preparation of linear aspects of Morphometric parameters. Drainage characteristic have been calculated such as stream length, mean stream length and Bifurcation Ratio for basin evolution studies, such studies are extremely useful for planning rainwater harvesting and Watershed Management

The detoxification capacity of the liver is well documented for a variety of substances including ethanol, organic pesticides, drugs, and metals. The piscean liver, although less enzymatically active than the mammalian counterpart (1), contains endoplasmic reticulum with an impressive repertoire of oxidizing, reducing, and conjugating abilities (2). Histopathologic changes are kncwn to occur in fish hepatocytes following in vivo exposure to arsenic (3); however, ultrastructural changes have not been reported. This study involved the morphometric analysis of intracellular changes in fish parynchymal hepatocytes and correlation with arsenic concentration in the liver.Green sunfish (Lepomis cyanellus, R.) were exposed to 0, 30, or 60 ppm arsenic (as sodium arsenate) at 20°C for 1, 2, or 3 week intervals before removal of livers for quantification of the arsenic burden (using neutron activation analysis) and morphometric analysis of ultrastructural alterations. Livers were cut into 1 mm cubes for fixation, dehydration, and embedding.
