Morphometry is a quantitative approach of analysing linear, areal and relief parameters to understand the role of neotectonic activity in geomorphologic evolution of a river basin. In the present study multi-disciplinary integrated approach using morphometric parameters along with remote sensing and GIS technique have been applied for determining the quantitative parameters indicative of neotectonic activity in the Parvati basin, Higher Himalaya. The lineament pattern observed in the basin shows major trend in NE-SW followed by NW-SE and NNE-SSW directions. The basin is a 6^th order drainage basin with dominating dendratic — trellis drainage pattern having very strong structural/tectonic control and is in its late youth stage of geomorphic development. Parvati basin shows coarse drainage density with fine texture suggesting more surface runoff and less infiltration in the area. The basin is highly elongated in shape tapering towards the south-west with high susceptibility to erosion with lower peak flow for longer duration. The above observations clearly indicate a tectonic and lithological control over the evolution of drainage pattern of Parvati basin.

形态计量学是一种分析线性，面积和起伏参数的定量方法，以了解新构造活动在流域地貌演化中的作用。在本研究中，采用形态学参数以及遥感和GIS技术的多学科综合方法已被用于确定指示喜马拉雅山帕尔瓦蒂盆地新构造活动的定量参数。在盆地中观察到的线型模式显示出NE-SW的主要趋势，随后是NW-SE和NNE-SSW方向。盆地是6^个阶流域盆地具有主要的树突状—格构式排水格局，具有很强的结构/构造控制，处于地貌发育的青年后期。帕尔瓦蒂盆地显示出较粗的排水密度和良好的质地，表明该地区地表径流更多且渗透较少。该盆地高度细长，向西南方向逐渐变细，对侵蚀的敏感性较高，且峰值流量较低，持续时间较长。以上观察清楚地表明了帕尔瓦蒂盆地排水模式演化的构造和岩性控制。
