Extraction of Drainage Pattern and Watershed from SRTM Data Using GIS Tools: A Case Study
Abstract: This paper proposes a fast and an inexpensive method for delineating the drainage and watershed of a sub-basin. Planning of the water resource management is evolving from simple local-scale problems toward complex spatially explicit regional scale. Such problems have to be addressed with distributed models that can compute runoff and erosion at different spatial and temporal scales. In general, watershed can range from as little as one hectare to hundreds …

Framework for High-Throughput Identification of Genomic Variants in Buffaloes
Abstract: The genetic improvement in livestock can be achieved through, i) selection and/through, ii) cross breeding. Conventional selection requires long time span and accurate performance records from the fields. The genetic improvement of Indian buffalo through cross breeding does not have much scope, as Indian buffaloes are genetically superior as compared to other foreign buffalo breeds. Thus selection based at molecular level will help us in identification of animals with desirable …
