The present study was aimed to investigate the morphometric indices and tectonic implications in sedimentary landscape of Wardha River sub-basin, Central India. Geologically, the study area is predominantly constituted with Vindhyan and Lower Gondwana sedimentary formations. In the study, IRS-1D, LISS-III satellite data and Geographic Information System (GIS) techniques were used to compute morphotectonic indices viz., channel sinuosity (S), drainage basin asymmetry factor (AF), transverse topographic symmetry factor (T), basin elongation ratio (Re), drainage basin shape (Bs) and mountain front sinuosity (Smf) to determine the tectonic activity of the study area. The terrain parameters such as aspect, slope and relative relief, river longitudinal profile and topographic profile of the basin were also computed by using Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM) of 30 m spatial resolution. The computed S index for 69 meandering locations ranges from 1.03 to1.97, and it indicates the foremost courser of the river sinuous to meandering. The Re value ranges between 0.47 and 0.74, and it suggests the active to slight tectonic implications in the study area. The Smf values range from 1.14 to 4.69, and it indicates that the study area had slight to active tectonic implication. The T values range from 0.06 to 0.94, and it also indicates the tectonic activity. The present investigation clearly demonstrates the potential of remote sensing and GIS-based approach in evaluation of morphotectonic indices, which reveals the implications of tectonic activity in sedimentary landscape of Wardha River sub-basin, Central India.

本研究旨在研究印度中部瓦尔达河次流域沉积景观的形态测量指标和构造意义。在地质上，研究区主要由 Vindhyan 和下冈瓦纳 (Lower Gondwana) 沉积地层构成。在研究中，IRS-1D、LISS-III 卫星数据和地理信息系统 (GIS) 技术被用于计算形态构造指数，即.、河道曲率（S）、流域不对称因子（AF）、横向地形对称因子（T）、盆地伸长率（Re）、流域形状（Bs）和山前曲率（Smf）来确定构造活动研究区。利用空间分辨率为30 m的航天飞机雷达地形任务（SRTM）数字高程模型（DEM）计算流域的坡向、坡度和相对起伏、河流纵剖面和地形剖面等地形参数。计算出的 69 个蜿蜒位置的 S 指数范围从 1.03 到 1.97，它表示河流蜿蜒到蜿蜒的最前面。Re 值介于 0.47 和 0.74 之间，表明研究区具有活动到轻微的构造影响。Smf 值范围从 1.14 到 4.69，表明研究区具有轻微至活动的构造意义。T 值范围从 0.06 到 0.94，它也表明构造活动。目前的调查清楚地证明了遥感和基于 GIS 的方法在评估形态构造指数方面的潜力，揭示了构造活动对印度中部瓦尔达河次流域沉积景观的影响。
