地球表面的自然行为是通过形态计量学分析及其环境方面进行的。形态计量学分析的不同方面取决于地球表面的地质变化。景观结构决定了河流从高到低的流向。河流形态计量学研究将新的地理形态特征与降雨、温度、气压、风等气候因子相结合。利用地形图绘制流域地图，划定河流和流域边界。strahler方法为这种复杂的形态计量分析分类流的顺序。内亚尔小流域的定量形态计量学分析包括网络分析；盆地几何;纹理分析与浮雕特征。利用地形起伏特征，生成了反映海岸地貌的山体起伏曲线。利用地理信息系统（GIS）编制了排水、排水密度、地貌、土地利用/覆被和坡度。本研究总结了参数和专题数据对认识内亚尔流域地貌问题和阐明水资源可持续发展的影响。
Abstract The natural behaviour of the earth’s surface is proceeding through morphometric analyses and its environmental aspects. Different aspects of morphometric analyses depends upon geological transformation of earth surface. The structure of landscape determines the river flow from upper to lower elevation. The morphometric studies of river integrates the new geo morphological features with the climatic factors such as rainfall, temperature, atmospheric pressure and wind. The drainage map is prepared using the toposheets, delineating the streams and watershed boundary. The strahler method classifies the stream orders for this sophisticated morphometric analyses. The quantitative morphometric analysis carried out in Neyyar sub-watershed includes Network analysis; Basin geometry; Texture analysis and Relief characteristics. The relief characteristics were used to generate the hypsometric curve which exhibit the monadnock and reliefs of coastal morphology. Drainage, Drainage Density, Geomorphology, Landuse/Landcover, and Slope were prepared using Geographic Information Systems (GIS). The present study concludes the influence of the parameters and thematic data in understanding the geomorphological problems and stating a sustainable development of water resources in Neyyar sub-watershed.
