Dynamics of soil organic carbon (SOC) are associated with soil erosion, yet there is a shortage of research concerning the relationship between soil erosion, SOC, and especially microbial biomass carbon (MBC). In this paper, we selected two typical slope landscapes including gentle and steep slopes from the Sichuan Basin, China, and used the (137)Cs technique to determine the effects of water e...

High quality 3D seismic data are used to assess the significance of mass-transport deposits (MTDs) to the evolution of the Pearl River Mouth Basin (South China Sea). Basal shear surfaces and lateral margins of seven recurrent MTDs are mapped to reveal a general NE-SW transport direction throughout the Late Miocene-Quaternary. A key result of our analysis is the perceived relationship between th...

This paper aims to present terrain characteristics of Kuya river basin specially relief zoning, aspect analysis, hill shade view, its relation with drainage conditions etc. Analysis of SRTM data in ERDAS Imagine and Arc GIS software reveals that there is no siginificant relief difference between upper and lower catchment of the basin but distinction between upper and lower catchments is very cl...

Due to the scarcity of field observations and geodetic measurements in catchments in the Karakoram Mountains in Western China, obtaining precipitation data for the high mountains involves large uncertainties and difficulties. In this study, we used a functional relationship between the annual glacier accumulation and summer temperature at the equilibrium line altitude (ELA) to derive precipitat...

Overarching goal of this paper was to evaluate automated and semi-automated methods of mapping wetlands using Landsat ETM+ and SRTM data. Automated methods consisted of: (a) slope derived from SRTM, (b) Tasseled cap Wetness Index (TCWI), (c) Normalized Difference Water Index (NDWI), (d) multi-band vegetation indices (MBVIs), (e) two band vegetation indices (TBVIs), (f) normalized difference veg...

[1] Sediment fans are a potentially useful and underexploited recorder of Earth’s climatic and tectonic history, but historical observations have led to conflicting views on the importance of tectonic, climatic, and lithologic variables in controlling fan morphology and deposition. A one-dimensional model of a sediment fan and its associated catchment is used to explore the sensitivity of such ...

It was shown in Spong [1999b] that the passive gaits for a planar 2DOF biped walking on a shallow slope (Goswami et al. [1995]) can be made slope invariant by a passivity based control that compensates only the gravitational torques acting on the biped. In this paper we extend these results to the general case of a 3-D, n-DOF robot. We show that if there exists a passive walking gait, i.e., if ...

This study investigated the relationship between the hydrological response of a river basin to anticipated urbanisation and its subbasin characteristics by applying a hydrological model (HSPF) with land use scenarios generated by an urban growth model (LEAM). The hydrological model was set up and run for the Kishwaukee River basin in northeastern Illinois, USA. The results show that the subbasi...

Geographic Information System (GIS) techniques are being increasingly and effectively used in morphometric analysis and groundwater potentiality mapping of drainage basin owing to its capabilities of manipulation, analysis, flexibility of experimentation and ability to extract topological attributes from various thematic maps, and to work as a unique tool for geospatial modelling. An attempt to...
