| 1 | Assessment of soil erosion in a tropical mountain river basin of the southern Western Ghats,India using RUSLE and GIS显示文摘Revised Universal Soil Loss Equation(RUSLE) model coupled with transport limited sediment delivery(TLSD) function was used to predict the longtime average annual soil loss, and to identify the critical erosion-/deposition-prone areas in a tropical mountain river basin, viz., Muthirapuzha River Basin(MRB; area=271.75 km^2), in the southern Western Ghats, India. Mean gross soil erosion in MRB is 14.36 t ha^(-1) yr^(-1), whereas mean net soil erosion(i.e., gross erosion-deposition) is only 3.60 t ha^(-1) yr^(-1)(i.e., roughly 25% of the gross erosion). Majority of the basin area(~86%) experiences only slight erosion(<5 t ha^(-1) yr^(-1)), and nearly 3% of the area functions as depositional environment for the eroded sediments(e.g., the terraces of stream reaches, the gentle plains as well as the foot slopes of the plateau scarps and the terrain with concordant summits). Although mean gross soil erosion rates in the natural vegetation belts are relatively higher, compared to agriculture, settlement/built-up areas and tea plantation, the sediment transport efficiency in agricultural areas and tea plantation is significantly high,reflecting the role of human activities on accelerated soil erosion. In MRB, on a mean basis, 0.42 t of soil organic carbon(SOC) content is being eroded per hectare annually, and SOC loss from the 4th order subbasins shows considerable differences, mainly due to the spatial variability in the gross soil erosion rates among the sub-basins. The quantitative results, on soil erosion and deposition, modelled using RUSLE and TLSD, are expected to be beneficial while formulating comprehensive land management strategies for reducing the extent of soil degradation in tropical mountain river basins. | Jobin Thomas Sabu Joseph K.P.Thrivikramji | 2018 | Geoscience Frontiers2018，9，3： | 7 |
| 2 | Morphometric analysis of the drainage system and its hydrological implications in the rain shadow regions, Kerala, India显示文摘雨阴影区域需要为持续的水资源管理的一个全面分水岭发展和管理计划。Pambar 河盆(PRB ) 躺在南部的西方的 Ghats 的雨阴影区域上,印度,在气候显示出显著 intra 盆的地方变化。morphometric 分析被做用地形学的地图和数字举起数据评估 PRB 的排水特征。PRB 被划分成十八第 4 顺序盆(SB1-SB18 ) ,分布式的各种各样的气候的坡度。更低的顺序流主要统治 PRB 和排水模式是地势和结构的一个函数。地面高度被把并且容易使更容易的洪水管理能在大暴风雨和 PRB 的伸长的形状期间玷污侵蚀。排水特征上的气候的影响显然在盆 morphometry 被强调。四个区别地不同的班基于 morphometric 类似被识别。水文学描述上的 morphometric 分析的意义被讨论,收获的水里的现在的学习的关联被详细解说和分析。 | Jobin THOMAS Sabu JOSEPH K.P.

| 3 | Morphometric aspects of a small tropical mountain river system,the southern Western Ghats,India显示文摘The Muthirapuzha watershed(MW)is one among the major tributaries of Periyarthe longest west flowing river in Kerala,India.A morphometric analysis was carried out to determine the spatial variations in the drainage characteristics of MW and its 14 fourth order sub-watersheds(SW1SW14)using Survey of India topographic maps and Landsat ETMimagery.The study revealed that the watershed includes a sixth order stream and lower order streams dominate the basin.Results did indicate that rainfall has a significant role in the drainage development whereas structure and relief of rocks dictate the drainage pattern.The asymmetry in the drainage distribution is correlated with the tectonic history of the Munnar plateau in the late Paleocene age.The watershed is moderate to well-drained and exhibited a geomorphic maturity in its physiographic development.The shape parameters revealed the elongated nature of MW and drainage network development in the watershed.Further,the analysis provided significant insight into the terrain characteristics.This study strongly brings to light,(a)the tendency of the watershed to soil loss and(b)the hydrological makeup of the subwatersheds,which combined helped to formulate a comprehensive watershed management plan. | Jobin Thomas Sabu Joseph K.P.Thrivikramaji | 2010 | International Journal of Digital Earth2010，3，2： | 5 |

| 10 | Land use and land cover changes over a century (1914 2007) in the Neyyar River Basin, Kerala: a remote sensing and GIS approach显示文摘Land use and land cover change,perhaps the most significant anthropogenic disturbance to the environment,mainly due to rapid urbanization/industrialization and large scale agricultural activities.In this paper,an attempt has been made to appraise land use/land cover changes over a century(19142007)in the Neyyar River Basin(L56 km;Area483.4 km2)in southern Keralaa biodiversity hot spot in Peninsular India.In this study,digital remote sensing data of the Indian Remote Sensing satellite series I-D(LISS III,20062007)on 1:50,000 scale,Survey of India(SOI)toposheet of 1914(1:63,360)and 1967(1:50,000)have been utilized to map various land use/land cover changes.Maps of different periods have been registered and resampled to similar geographic coordinates using ERDAS Imagine 9.0.The most notable changes include decreases in areas of paddy cultivation,mixed crops,scrub lands and evergreen forests,and increases in built-up areas,rubber plantations,dense mixed forests,and water bodies.Further,large scale exploitation of flood plain mud and river sand have reached menacing proportions leading to bank caving and cut offs at channel bends.Conservation of land and water resources forms an important aspect of ecosystem management in the basin. | R.V.Sheeja Sabu Joseph D.S.Jaya R.S.Baiju | 2011 | International Journal of Digital Earth2011，4，3： | 1 |
