Knowledge on spatio-temporal variations in planform, hydraulic geometry, and bed-level variations of alluvial streams is required for planning and development of hydraulic structures and bank protection works. In the current study, a Geographic Information System (GIS) has been used to analyze topographical maps, multi-temporal remotely sensed imagery, and hydrologic and hydraulic data to extract the morphological parameters of the Upper Tapi River, India. The river has been found to have consistent migration towards the northern direction, with erosion/deposition on right/left banks. The river has not experienced any major meander except in the lower reaches of the Upper Tapi Gorge and minor braiding conditions at the location where the river emerges from mountainous topography to the plain region. The analyzed river cross sections were found to be depth dominated, and contain large flows within the channel banks. The cross-sections exhibited moderate channel bed adjustments in 1994, 2006, and 2007 wherein excessive sediment flux and stream power were capable of causing morphological changes in the river. High intensity rainfall in the subcatchment resulted in high sediment flux into the river during 1994, which was reported to cause significant aggradation at the downgauging station. The analysis of sediment flux into the river in conjunction with decadal land use land cover, revealed that sediment yield from the catchment was reduced during 2000–2010 due to an increase in water bodies in the form of minor hydraulic structures. The entry of comparatively less sediment laden water into the river, resulted in moderate bed degradation especially in 2006 and 2007 as observed at the downstream station. The methodology applied in the current study is generic in nature and can be applied to other rivers to identify their morphological issues.

水工建筑物和堤岸保护工程的规划和开发需要有关平面形态、水力几何学和河床水平变化的时空变化方面的知识。在目前的研究中，地理信息系统 (GIS) 已被用于分析地形图、多时相遥感图像以及水文和水文数据，以提取印度塔皮河上游的形态参数。已发现这条河一直向北迁移，右岸/左岸有侵蚀/沉积。除了在上塔皮峡谷下游和河流从山地地形到平原地区出现的轻微辫状条件外，这条河没有经历任何大的曲折。发现分析的河流横截面以深度为主，并在河道内包含大流量。1994 年、2006 年和 2007 年横截面表现出适度的河床调整，其中过多的泥沙通量和河流动力能够导致河流形态变化。1994 年，子汇水面积的高强度降雨导致流入河流的高泥沙通量，据报道这导致了减量站的显着集聚。对流入河流的泥沙通量与十年土地利用土地覆盖情况的分析表明，由于小型水力结构形式的水体增加，流域的泥沙产量在 2000 年至 2010 年期间减少。含沙量相对较少的水进入河流，导致中度床层退化，尤其是在 2006 和 2007 年，如在下游站观察到的那样。当前研究中应用的方法本质上是通用的，可以应用于其他河流以识别它们的形态问题。
