Quantitative morphometric analysis of Dhanari watershed has been done using remote sensing and Geographical Information System (GIS). The impact of climate, lithology, tectonics, structural antecedents, vegetation cover and land use on hydrological processes is assessed by quantifying geomorphic parameters. The Dhanari River (a tributary of the Bhagirathi River) and its tributaries Dhanpati Gad and Kali Gad forms Dhanari watershed covering 91.8 Km² area. Several geomorphic aspects viz. linear, areal, relief were computed to comprehend potentials of soil erosion, groundwater, flood vulnerability and the geomorphic response of watershed. LISS-III image is used to generate the Land Use and Land Cover (LULC) map and assess the watershed dynamics. Values of computed hypsometric integral and morphometric parameters viz. drainage density (\(D_{{\text{d}}}\)), stream frequency (\(F_{{\text{s}}}\)), stream length ratio (\(L_{{{\text{ur}}}}\)), bifurcation ratio (\(R_{{\text{b}}}\)), rho coefficient (ρ), drainage texture (\(D_{{\text{t}}}\)), circularity ratio (\(R_{{\text{c}}}\)), relief ratio (\(R_{{{\text{hl}}}}\)), elongation ratio (\(R_{{\text{e}}}\)), form factor (\(F_{{\text{f}}}\)), basin shape (\(B_{{\text{s}}}\)), drainage intensity (\(D_{{\text{i}}}\)), compactness coefficient (\(C_{{\text{c}}}\)) and infiltration number (\(I_{{\text{f}}}\)) have shown a moderate and steady erosion rate, with low groundwater potential and low to moderate flood vulnerability in the watershed. Hypsometry presents a dependable geomorphic parameter to understand the erosion and geomorphic response of a watershed to hydrological processes. Hypsometric integral value (0.51) of Dhanari watershed suggests a mature topography with steady erosion in the watershed.

已使用遥感和地理信息系统 (GIS) 对 Dhanari 流域进行了定量形态测量分析。通过量化地貌参数来评估气候、岩性、构造、结构前因、植被覆盖和土地利用对水文过程的影响。Dhanari 河（Bhagirathi 河的一条支流）及其支流 Dhanpati Gad 和 Kali Gad 形成了 Dhanari 流域，覆盖 91.8 公里²区域。几个地貌方面即。计算线性、面积、地势以了解土壤侵蚀、地下水、洪水脆弱性和流域地貌响应的潜力。LISS-III 图像用于生成土地利用和土地覆盖 (LULC) 地图并评估流域动态。计算的测压积分和形态测量参数的值。排水密度（\(D_{{\text{d}}}\)），河流频率（\(F_{{\text{s}}}\)），河流长度比（\(L_{{{\text {ur}}}}\) )、分叉比( \(R_{{\text{b}}}\) )、rho系数(ρ)、排水结构( \(D_{{\text{t}}} \) )、圆度比 ( \(R_{{\text{c}}}\) )、浮雕比 ( \(R_{{{\text{hl}}}}}\)）、伸长率（\(R_{{\text{e}}}\)）、形状因子（\(F_{{\text{f}}}\)）、盆形（\(B_{{\text {s}}}\) )、排水强度（\(D_{{\text{i}}}\)）、密实系数（\(C_{{\text{c}}}\)）和入渗数（\(I_{{\text{f}}}\) ) ) 显示出中等和稳定的侵蚀率，具有低地下水潜力和流域中低至中等的洪水脆弱性。Hypsometry 提供了一个可靠的地貌参数，以了解流域对水文过程的侵蚀和地貌响应。Dhanari 流域的 Hypsometric 积分值 (0.51) 表明流域中具有稳定侵蚀的成熟地形。
