  • Officiers topographes et topographes-alpinistes dans les Alpes françaises, 1890-1940
  • militaires français développèrent les mesures tachéométriques (et plus barométriques). Vers 1900 la professionnalisation des topographes alpinistes, la création d'une commission de topographie qui se rapprocha du Club alpin français développa cette

  • Simulating meander evolution of the Geul River (the Netherlands) using a topographic steering model
  • The AA. examine the meandering character of the Geul River using a numerical river meandering model. The main aim is to test and calibrate a topographic steering meander model. In this case study, special attention is paid to the incorporation

  • Evolution of the lowest amazon basin modeled from the integration of geological and SRTM topographic data
  • Morphologic features obtained from Shuttle Radar Topographic Mission (SRTM) data, integrated with geologic information, are emphasized in this paper in order to provide the basis for understanding the development of the lowest Amazon drainage basin

  • Topographic controls on the invasion of Pteronia incana (Blue bush) onto hillslopes in Ngqushwa (formerly Peddie) district, Eastern Cape, South Africa
  • The study combined field observations with image analysis based on high-resolution infrared imagery. A Digital Elevation Model (DEM) of 20 m spatial resolution was used to derive terrain parameters. The Topographic Wetness Index (WI), a component

  • Vegetation response to a topographical-soil gradient

  • topographical wetness index (TWI) had been used. Topographical wetness index shows water accumulation in a given location and is a function of slope and upslope specific catchment area. - (IKR)

  • This paper predicts the geographic distribution and size of gullies across central Lebanon using a geographic information system (GIS) and terrain analysis. Eleven primary and three secondary topographic variables were generated and used along
  • topographic wetness and sediment transport capacity indices and explained 80% of the variability in field gully measurements.

  • using the Cs 137 technique. The AA. determined that the patterns of water and tillage erosion across the landscapes are mainly dependent on topographic features and they are fundamentally different within topographically complex landscapes. Most soil

  • Rock temperature data are presented for a variety of topographic localities at a high Drakensberg site. The aim is to investigate the spatio-temporal variations of surface rock temperatures in high Drakensberg basalt. The temperature results

  • explorers have reported of their expeditions to silk road and made an evaluation. The paper describes three phases of exploration : a period of topographical and geographical enquire, an archaeological period and since 1911 a period of political interest

  • The survey of geographical names for the Italian topographical maps of Libya produced a huge debate that interested colonialist, geographic and cartographic societies. Some Arabic language students (Nallino, Griffini) entrusted

  • The aim of this paper is to refine previous conceptual models of muddy flood triggering by determining rainfall and topographic thresholds for the Belgian loess belt as well as to quantify off-site impacts of muddy floods. Twenty municipalities

  • The aim of this study is to investigate spatial variability of rock fragment (RF) cover and size with respect to topographic position, slope and aspect in 3 dolines in Sierra de Gádor. The results indicate that cover percentage of small RFs
