Himalaya is one of the youngest and greatest mountain ranges in the world and is one of the world’s most erosion-prone regions. Reliable information on the basin hydrology, physico-chemical weathering, and runoff dynamics is essential to develop an appropriate policies for sustainable, socially acceptable, ecological, and economically viable development of the mountainous rivers. The current study uses a numerical model and GIS tools to estimate run-off volume and sediment production rate and generates morphometric parameters like drainage network, geometry, drainage texture, aerial, and relief characteristics in the Sindh River basin of Kashmir Himalaya, to understand the erosion dynamics of the basin. The basin is dominated by a dendritic drainage pattern with a drainage density of 2.60 km/sq km. The aerial parameters such as elongation ratio, circulatory ratio, compactness coefficient, and rotundity factor show that the basin is elongated in shape with a lower peak flow period, and the basin is structurally complex with high relative relief. The estimated basin run-off volume and sediment production rate of 11.31 (sq.km-cm/sq.km) and 0.002 (ha-m/100 sq.km/year), respectively, suggest that the Sindh basin can be categorized under the low run-off zone and less soil erosion occurs when compared to other Indian Himalayan rivers. The paper aims to fill the knowledge gap concerning the estimation of hydro-sedimentological flows in the Sindh basin. In this context, present work to estimate run-off volume and sediment production rate was carried out using morphometric features to help the decision-makers in framing sustainable land use policies and practices for the region.

应用地貌测量法估算水文沉积流量和阳离子风化率:了解克什米尔喜马拉雅地区信德盆地的可持续土地利用政策

喜马拉雅山是世界上最年轻、最大的山脉之一,也是世界上最易发生侵蚀的地区之一。有关流域水文、物理化学风化和径流动态的可靠信息对于制定适当的政策以实现山区河流的可持续、社会可接受、生态和经济可行的发展至关重要。目前的研究使用数值模型和 GIS 工具来估算径流量和沉积物产生率,并生成克什米尔喜马拉雅信德河流域的排水网络、几何形状、排水结构、空中和地形特征等形态测量参数,以了解流域侵蚀动力学。盆地以树状流域为主,流域密度为2.60 km/sq km。伸长率等空中参数,环流比、密实度系数和圆度因子表明,盆地形状拉长,流量高峰期较低,盆地结构复杂,相对起伏较大。估计的流域径流量和沉积物产量分别为 11.31 (sq.km-cm/sq.km) 和 0.002 (ha-m/100 sq.km/year),表明信德流域可以归类为与其他印度喜马拉雅河流相比,低径流区和较少的土壤侵蚀发生。本文旨在填补有关信德盆地水文沉积流量估算的知识空白。在此背景下,目前估算径流量和沉积物生产率的工作是使用形态测量特征来帮助决策者制定该地区可持续土地利用政策和实践的。致密系数和圆度系数表明盆地呈拉长状,流量高峰期较低,盆地结构复杂,相对起伏较大。估计的流域径流量和沉积物产量分别为 11.31 (sq.km-cm/sq.km) 和 0.002 (ha-m/100 sq.km/year),表明信德流域可以归类为与其他印度喜马拉雅河流相比,低径流区和较少的土壤侵蚀发生。本文旨在填补有关信德盆地水文沉积流量估算的知识空白。在此背景下,目前估算径流量和沉积物生产率的工作是使用形态测量特征来帮助决策者制定该地区可持续土地利用政策和实践的。致密系数和圆度系数表明盆地呈拉长状,流量高峰期较低,盆地结构复杂,相对起伏较大。估计的流域径流量和沉积物产量分别为 11.31 (sq.km-cm/sq.km) 和 0.002 (ha-m/100 sq.km/year),表明信德流域可以归类为与其他印度喜马拉雅河流相比,低径流区和较少的土壤侵蚀发生。本文旨在填补有关信德盆地水文沉积流量估算的知识空白。在此背景下,目前估算径流量和沉积物生产率的工作是使用形态测量特征来帮助决策者制定该地区可持续土地利用政策和实践的。和圆度因子表明,盆地呈拉长状,流量高峰期较低,盆地结构复杂,相对起伏较大。估计的流域径流量和沉积物产量分别为 11.31 (sq.km-cm/sq.km) 和 0.002 (ha-m/100 sq.km/year),表明信德流域可以归类为与其他印度喜马拉雅河流相比,低径流区和较少的土壤侵蚀发生。本文旨在填补有关信德盆地水文沉积流量估算的知识空白。在此背景下,目前估算径流量和沉积物生产率的工作是使用形态测量特征来帮助决策者制定该地区可持续土地利用政策和实践的。和圆度因子表明,盆地呈拉长状,流量高峰期较低,盆地结构复杂,相对起伏较大。估计的流域径流量和沉积物产量分别为 11.31 (sq.km-cm/sq.km) 和 0.002 (ha-m/100 sq.km/year),表明信德流域可以归类为与其他印度喜马拉雅河流相比,低径流区和较少的土壤侵蚀发生。本文旨在填补有关信德盆地水文沉积流量估算的知识空白。在此背景下,目前估算径流量和沉积物生产率的工作是使用形态测量特征来帮助决策者制定该地区可持续土地利用政策和实践的。
