This new reinterpretation of the Quaternary evolution of the Pecora River area has several implications, in particular on the nature of the arsenic anomaly known in this area and mainly confined to the fluvial terrigenous deposits. Specifically
, the erosion and dispersal of As-bearing mineralization emplaced between the late Pliocene and the Quaternary in fractures and faults affecting the bedrock of the Arsenti Mount area, was possibly driven by the sedimentary development of the Pecora River
catchment resulting in the landforms and deposits described in this study. As a consequence, the As anomaly known in this area may have resulted from fully natural phenomena such as relief denudation and sediment dispersal. - (NF)
Supporting large-area, sample-based forest inventories whith very high spatial resolution satellite imagery
In this paper, the AA. synthesize the state-of-the-art in the use of VHSR remotely sensed imagery for forest inventory and monitoring. Based upon this review, they develop a framework for updating a sample-based, large-area forest inventory
attribution, manual interpretation, and indirect attribute modelling. Although designed to support the information needs of the Canadian NFI, the framework presented herein could be adapted to support other sample-based, large-area forest monitoring

Four systems are designed to analyze relations on trade area development of city (energy, communications, culture and education, transportation). Infrastructure development has a significative impact on trade area development of city. The biggest
Phytogenic hillocks are landforms typical for areas built of blown sands. They are an effect of cooperation of wind with bushy vegetation of specific features. One of such areas is located in Silesian Upland in southern Poland (so-called Bledow
Desert), which beginning goes back to the Middle Ages. It is connected with deforestation, mainly for the needs of contemporary lead, silver and zinc metallurgy. Presently this area is covered in result of intentional vegetation introduction as well
as by natural vegetation expansion and succession. One of species intensively entering into this area is Salix arenaria. And just at participation of this bushy willow in deflation areas very characteristic phytogenic hillocks of heights reaching up to 1,5 m
are here created using more humid clayey insertions of substratum. In area discussed it is possible to observe different development stages of phytogenic hillocks : from initial through mature to disappearing ones. The age of hills was determined
Morphodynamics and morphological changes of the last 50 years in a badland sample area of Southern Tuscany (Italy)
The aim of this geomorphologic study was to analyse the recent morphologic evolution of calanchi badlands over a 50 years' period (1955-2006) and to evaluate the mean erosion rate in areas situated in Southern Tuscany. These areas are characterised
) and photogeological analysis of a 30 km2 area. The results indicated that the effects of graviatational processes have increased over the last 10 years while sheet-wash action has been less intense over the same period. In addition, the morphodynamic analysis strongly
suggest that anthropogenic action should not be underestimated as a major force in shaping the landscape in the study area over the last 50 years.

Based on qualitative and quantitative methods, the AA. constructed an integrated indicator system to assess the status of water resources and urbanization system in arid area, and established an AHP model reformed by entropy technology to evaluate
the temporal and spatial variations of water resources constraint intensity on urbanization. This model is applied to the Hexi Corridor, a typical arid area in NW China. Results show that, water resources constraint intensity on urbanization in the Hexi
is an effective method to analyze the conflicts between water resources and urbanization system in arid area.

This work explores the question: is pavement a proxy measure of human impact on the environment? The AA. explore and evaluate the use of satellite derived density grids of constructed area (aka ‘pavement’ or ‘impervious surface’) in the calculation
of national and subnational ‘ecological footprints’. They generated a global constructed area density grid for the 2000—2001 period using satellite observed nighttime lights and a population count grid from the US Department of Energy. Satellite data inputs
to the population product include MODIS landcover, SRTM topography and high-resolution imagery. Calibration of the global constructed area density product was derived from high-resolution aerial photographs. The AA. demonstrate that a satellite derived constructed
area per person index can serve as a proxy measure of ecological footprints at both the national and subnational level. This relatively simple and globally uniform measure of human impact on the environment correlates strongly with other more difficult
The aim of selecting an optimal scale is to determine the grid cell for the monitoring of land-use and to investigate the scale law of land area in the Tarim River Basin in Xinjiang, which will allow a maximum diversity of the land types in unit
grid area, facilating the ground experiment design and the remote survey in the future. Selecting the suitable scale consisted of 3 steps : 1) area mode is derived from statistics of frequency distribution of areas of the land types in the Tarim River
Basin; 2) according to the mode of the area, the normalized scale variances (NSV) was calculated and the suitable scale of the ecological monitoring was discussed; 3) the diversity indices and the fractal dimension figured to supplement the methods
The AA. show the results from monitoring the natural recovery of beach areas at Khuk Khak and Bang Niang tidal channels of Khao Lak area, Phang-nga, Thailand. A series of satellite images before and after the tsunami event was employed
for calculating the beach area and locating the position of the changed shoreline. Field surveys to follow-up the development of the post-tsunami beach area were conducted from 2005 to 2007 and the yearly beach profile was measured in 2006. As a result
, the scoured beach areas where the tidal channel inlets were located underwent continuous recovery. The present situation of the beach zone has almost completed reversion back to the equilibrium stage and this has occurred within 2 years after the tsunami event.
This paper proposes an innovative, non-intrusive method for mapping waterway characteristics in riverine areas. The technique uses photogrammetry to provide quantitative information about the dry area in the vicinity of the waterways (banks
and floodplain) and image processing algorithms to characterize the flow. Riverside images of a riverine area are decomposed into quasi-planar areas and ortho-rectified and re-assembled to obtain a panoramic ortho-view of the area of interest. Morphological
