Predicting monthly precipitation with multivariate regression methods using geographic and topographic information
Multivariate regression models that integrate topographic and geographic information are developed to predict monthly precipitation in the Daqing Mountains of northern China. Five geographic and topographic factors, including longitude, latitude
, elevation, slope, and aspect, are taken into account in the model development. The data are acquired from a 100 m resolution DEM of the national topographic databases. Measured precipitation data at 56 stations between 1955 and 1990 are used for model
development, and a leave-one-out cross-validation method is used for model evaluation. The model explains most of the spatial variability in monthly precipitation, and can also quantify the relative importance of different geographic and topographic variables.
Topographic variation in burning-induced loss of carbon from organic soils in Tasmanian moorlands
and after 4 years. They also compared soil surface temperatures over summer between burned and unburned moorland. The topographic wetness index was strongly related to soil and organic matter loss, while fire severity, slope and vegetation cover were less
Monitoring topographic changes in a periglacial high-mountain face using high-resolution DTMs, Monte Rosa East Face, Italian Alps
This paper describes a remote sensing-based approach for detailed topographic investigations in steep periglacial high-mountain faces. The study was conducted in the European Alps, at the permafrost-affected and partially glacierised east face

and its border areas. Every landscape is described physically and historically. The borderlines and the location on historical and new topographic maps are given. All informations about the location and the spatial division of the landscapes are drawn
incorporated into a homogenous database and subsequently applied in the investigation of the morphological patterns of these mouths, and the analysis of their influencing factors. River mouths in this study occur in 2 distinctive topographic settings with quite
distinctive behavior : barrier topography and funnel topography. It is concluded that the topographic setting of the beach is the primary influencing factor on the morphology of the mouths studied.
distribution of SOC in this system, plots previously characterized by topographic position, vegetation type and stand age were related to soil depth and SOC. Additional factors were also investigated, including topographically-related differences in litter
Influence of topographic and edaphic factors on vulnerability to soil degradation due to cattle grazing in humid tropical mountains in northern Honduras
The aim of this study was to analyze relationships between topographical properties derived from DEM and soil distribution and to discuss their applicability in Digital Soil Mapping (DSM). The study was carried out in the Borujen area of central
relationships. The results obtained show that there was a relatively strong correspondence between soils' series distribution and topographical properties.
topographic profiles of parts of the Kali River Basin bring out preferred stream migration in response to Quaternary ground tilting of southeast and northwest directions across the North Almora Thrust. An oblique-slip type of movement along the fault has been
In this paper the spatial and temporal responses of the Someşu Mic River to natural and anthropogenic controls over the past 150 years are analysed, based on a series of morphometric parameters extracted from 5 successive sets of topographic maps
The Karakoram terrane in Northern Pakistan is geologically equivalent to the Qiangtang terrane of central Tibet but unlike Tibet shows extreme topographic relief, high uplift-exhumation and erosion rates and exposes deep crustal metamorphic
In this study, the AA. present a pilot study focusing on the evaluation of topographical factors (elementary landforms, slope profile, clast size) that predispose the formation of different microclimatic regimes at screes that have similar physico

This study characterizes the distribution and thickness of historical overbank sedimentation along the upper James River through topographic surveys, subsurface floodplain sediment sampling, and historical aerial photo analysis. Stratigraphic
The Pambar River Basin (PRB) lies on the rain shadow region of the southern Western Ghats, India, where climate showed marked intra-basin variation. A morphometric analysis was done to evaluate the drainage characteristics of PRB using topographical
