The contribution to sea level rise from Patagonian icefields is one of the largest mass losses outside the large ice sheets of Antarctica and Greenland. However, only a few studies have provided large-scale assessments in a spatially detailed way to address the reaction of individual glaciers in Patagonia and hence to better understand and explain the underlying processes. In this work, we use ...

The relationship between topography, land use, and topsoil moisture storage is investigated for a small catchment with undulating deep loess hilslopes in the south of the Netherlands. For a period of 10 months, soil moisture profiles have been measured weekly at 15 locations throughout the catchment. A Generalized Additive Model was employed to find relationships between the various factors inf...

determination of the thickness of a mountains glacier like alamkooh is very difficult due to its extremely cold climate conditions and high elevation, risk of falling large snow segments or balls and coarse topography of the glacier. in this research, due to the transparency of ice for electromagnetic (em) waves, and also, that ground penetrating radar (gpr) method is non-destructive, fast and ...

In this study, the interaction between atmosphere and earth surface and its effect on the simulation of Sistan wind structure in the East of Iranian plateau is investigated. For this purpose, four experiments have been carried out with RegCM4, with horizontal resolution of 20 km. In non-topography experiments, the model was implemented in three different conditions. The results indicated that t...

low cereal and legumes yields and their rwp index are mainly due to poor distribution of rainfall and poor agronomic management practices. rainfed barley yield and rain water productivity (rwp, defined as rainfed grain yield divided by the total crop season annual rainfall water) in the dry farming are considerable by topography and latitude. yield data, rainfall, altitude and latitude of 182 p...

Community Health Status Indicators Project " (1) is a fascinating article that describes how county-level poverty data were created into maps. Although appropriate for review by my students, the article raises the issue of how to explain such maps to elected officials. I have a hard enough time understanding the math, and I doubt whether one in a thousand elected officials could understand the ...

The Mediterranean area is one of the most significantly altered hotspots on Earth, since it has been intensively affected by human activity for millennia. As a result, only 4.7% of its primary vegetation remained unaltered and the landscape has been repeatedly transformed. In this paper, we aimed at detecting both the direction and the rate of landscape change focusing on the effects of human a...
