| 1 | Estimation of soil erosion risk within a small mountainous sub-watershed in Kerala,India,using Revised Universal Soil Loss Equation(RUSLE) and geo-information technology显示文摘集成的全面方法论修订了通用土壤损失系统(GIS ) 技术被采用决定 forested 的土壤侵蚀危险的方程(RUSLE ) 模型和地理信息在 Kerala 的多山的亚分水岭,印度。年度土壤侵蚀率的空间模式被在一个光栅集成 geo 环境的变量获得基于的 GIS 方法。包括的 GIS 数据层,降雨 erosivity (R) ,土壤 erodability (K) ,斜坡长度和险峻,盖子管理(C) 和保存实践(P) 因素(LS ) 被计算决定他们的效果在区域的平均年度的土壤损失。年度土壤侵蚀的结果的地图在陡峭的方面斜坡上与与草土地区域,降级的森林和脱落森林的一种靠近的关系显示出 17.73 t h-1 y-1 的最大的土壤损失(与高 LS ) 。与 RUSLE 方法和 GIS 产生的空间侵蚀地图能在为土地在环境地敏感的多山的区域计划和管理导出策略用作有效输入。 | V.Prasannakumar H.Vijith S.Abinod N.Geetha | 2012 | Geoscience Frontiers2012，3，2： | 35 |
| 2 | Magnetic fabrics in characterization of magma emplacement and tectonic evolution of the Moyar Shear Zone,South India显示文摘Moyar 砍南方印第安人 granulite 地面的地区(MSZ ) 招待突出的正长岩 pluton (560 妈) 和联系 NW-SE 到 NE-SW trending mafic 塘群(65 妈和 95 妈) 。初步的磁性的织物在 mafic 女同性恋学习,用 Anisotropy 磁性(AMS ) 容易感受地学习在低地,显示连续炮兵阵地和可变岩浆流动方向。在这些女同性恋的磁性的线条和生叶与在 MSZ 糜棱岩的 mesoscopic 织物相同,显示砍地区指导炮兵阵地。在女同性恋的磁性的线条的空间分发建议来源岩浆从被移植了的一根普通水管。磁性的生叶轨道有 sigmoidal 形状到 pluton 和曲线的北方进建议右感觉的 MSZ 砍。为在正长岩 pluton 的磁性的织物和在糜棱岩的测量领域织物的相同织物条件沿着原生地外壳的规模显示 syntectonic 炮兵阵地右砍有重复复活历史的地区。 | P.Pratheesh V.Prasannakumar K.R.Praveen | 2013 | Geoscience Frontiers2013，4，1： | 2 |
| 3 | Applicability of SRTM data for landform characterisation and geomorphometry: a comparison with contour-derived parameters显示文摘Geomorphologic and hydrologic research heavily depends on digital elevation models(DEM)which are currently being prepared from digital contours.The present study examines the use and applicability of freely available global elevation data source(3 arc seconds finished Shuttle Radar Topography Mission(SRTM))in landform characterisation,geomorphometry,river basin studies and other allied scientific applications in comparison with contour elevation data derived from the surveyed topographical sheets.The relief data extracted from a conventionally digitised geo-information science dataset of topographic contours(1:50,000)are compared with the SRTM-DEM and the variations are analysed.The automated geomorphometric and landform parameters derived from the contour DEM and the computed statistical properties of those parameters have substantial agreement with the same parameters derived from the SRTM-DEM.At the same time,localised variations also exist in some spatial domains.Derivative landscape analysis outputs from the SRTM-DEM suggest the wide acceptability and applicability of the freely available SRTM data source,especially in the regional scale applications related to hydrological modelling,terrain characterisation,disaster management and land degradation studies. | V.Prasannakumar RShiny NGeetha HVijith | 2011 | International Journal of Digital Earth2011，4，5： | 1 |
| 4 | Role of Multi-Generation Dyke Emplacements in Moyar-Bhavani Shear Zone, South India显示文摘The Moyar-Bhavani Shear Zone(MBSZ)of the South Indian Granulite Terrain(SIGT),a complex continental block formed by the accretion of various crustal units during the Archaean to Neoproterozoic,bear evidences | P.Pratheesh V.Prasannakumar K.R.Praveen C.Vikas | 2016 | Acta Geologica Sinica(English Edition)2016，90，S1： | 0 |
