300 MW Baspa II is India’s largest private hydroelectric facility, located at the Baspa River which is an important left-hand tributary to the Sutlej River in the NW Himalaya (India). In this valley the Sangla palaeo-lake has been dammed around 8200 yr BP behind a rock-avalanche dam and Baspa II is located exactly on top of this palaeo-lake. This special location represents a very rare possibil...

This paper follows a geostatistical approach for the evaluation, modelling and visualization of the possible local interactions between natural components and built-up elements in seismic risk analysis. This method, applied to old town centre of Potenza hilltop town, offers a new point of view for civil protection planning using kernel density and autocorrelation indexes maps to analyse macrose...

The “laguna de El Conde” wetland Ramsar reserve (Córdoba, Spain) depicts a geomorphological progression with different Pleistocene and Holocene stages and reaching a concluding situation by anthropic manipulation of the local network of tributaries. The nature of the sediments carried into the Triassic-gypsum depression where the reserve is situated. Further, dissolution processes and the forma...

We have been trying to make a recipe for predicting ground motions from future large earthquakes. To do that the most important factors are the source characterizations for complex rupture processes and the Green’s function estimations for realistic geological structures. We attempt to formulate the source characterizations based on recent results of the waveform source inversion. There are two...

Title of Document: IDENTIFYING LANDSLIDE HAZARDS IN A TROPICAL MOUNTAIN ENVIRONMENT, USING GEOMORPHOLOGIC AND PROBABILISTIC APPROACHES José Gregorio Roa-Lobo PhD, 2007 Directed By: Prof. Michael Kearney, Department of Geography The objective of this study is the performance, assessing, comparison and validation of a set of three landslide hazard maps: The geomorphological, the multicriteria eva...

In order to determine the source and critical areas of wind Erosion, Sistan Plain, IRIFR-E.A method was applied. According to geomorphological investigations, the studied area consists of the following two main units namely: Pediment with 1 type and 8 geomorphological facies, and playa with 2 types of flatland and desert type that includes 9 geomorphological facies. On the basis of sediment, th...

A high resolution DEM (1 ms spacing) derived from an airborne LiDAR campaign was 10 used in an attempt to characterize the structural and erosive elements of the geometry of the Pettino 11 fault, a seismogenic normal fault in Central Apennines (Italy). Four 90to 280 m -long fault scarp 12 segments were selected and the surface between the base and the top of the scarps was analyzed 13 through t...

This paper presents a study about the potential of spectral unmixing of hyperspectral satellite image data for targeting and quantification of mineral content in limestone and bauxite rich areas in southern India. ASTER image (acquired in the VNIR and SWIR regions) has been used in conjunction with SRTM – DEM and field studies. A new approach of spectral unmixing of ASTER image data delineated ...

Five rapid visual stream assessment methods were applied to 65 restored streams in North Carolina, and the results were correlated with measured macroinvertebrate community metrics to evaluate predictive ability. The USEPA Rapid Bioassessment Protocol (RBP), USDA Stream Visual Assessment Protocol (SVAP), Peterson’s Riparian Channel and Environmental Inventory (RCE), NCSU Eco-Geomorphological As...

Sphericity and roundness have been employed in sedimentological and geomorphological studies to represent the gross shape of a gravel particle. The original complex definitions of gravel sphericity and roundness led to the use of visual charts or simplified parameters. Although the accurate derivation of sphericity requires the surface area of a gravel particle, manual measurement of the area i...
