This study is a first in a Saharan region. Following a collaboration between soil scientists and geomorphologists a geomorphological mapping was realized. This work aims to understand the evolution of Saharan soils .The result we obtained demonstrated the presence of five geomorphological soil level. Each level and defined as soil with special chemical, physical and genetic characteristic.

Due to the blending, we don't speak of "terroir" in Champagne vineyard. But, in fact, oenologists of each "Maison de Champagne" make their wines with different grapes varieties harvested in different plots. This work is founded only on traditional knowledge and wine tasting.Choice during works of winegrowing and wine tasting can be improved with scientific studies of the "micro-terroirs". That's why, some years ago, a reflection begun on the concept of "terroir" in Champagne. This article presents a case study of Sezanne, a vineyard area of 22.8 km2, unknown and not classified among the best vineyards. It carries out the relation between physics and historic parameters, and how the wine growers modify plantations to adapt themselves to the requests of the consumers, while respecting the traditions and the natural conditions.

A new residential district is under construction on the southern slope of Oradea Hills located in the eastern part of the town of Oradea and on right bank of the Cris Repede. The new houses are distributed according to two alignments: one on the top of the interfluve and the other, denser, at the bottom of the slope. Gardens and terrace cultivation can be found between these two developments. Therefore, this green slope in the vicinity of the urban center constitutes a place favourable for urban extension. Nevertheless, numerous landslides can be found on these slopes composed of late Tertiary detrital formations (sands, marls and sandstones) deposited by the Pannonic Sea. Several types of landslides were observed: rotational, muddy castings and side extensions locally known as "glimées". These landslides can be explained by the conjunction of favourable factors which can be permanent (topography, geology, hydrology) or occasional (precipitations). Chronological study made it possible to identify four generations of landslides. Signs such as cracks affecting walls or warped trees show that these movements are still active.
