. The earthquakes of 1894, 1944, 1952 and 1977 occurred in the province San Juan central-wesern Argentina caused numerous processes soils sediment liquefaction, including those Ullum-Zonda valley. Historical records showed cracks, sand volcanoes, craters differential settlements, which significant damage to housing agro-industrial sector region. In this work, we carried out a study susceptibili...

introduction interaction between internal and external processes of the earth during time plays an important role in formation and landforms transformation. we can identify course of their process changes with landform survey. in the middle parts of iran, there are several geomorphologic evidence of arid and rainy climate changes. playaes and lakes or generally internal holes had an important r...

Yalvaç and Ilgın basins surrounding the Sultandağları opened due to orogenic collapse in early Miocene. The NW-SE trending Çakırçal Akşehir Faults, forming boundaries with these basins, caused both opening of uplifting Sultandağları. During Miocene-Pliocene period, alluvial fans fed from developed on basin margins, while lacustrine carbonate clastic depositions occurred basin's interior. Alluvi...

Depth dependence of permeability can appear in any geologic setting; however, vertical trends in alluvial gravel deposits are poorly understood because of the high variability of hydraulic conductivity K in monotonic sequences. This paper examines the sensitivity of depth-decaying permeability through heat transport simulation around a river's losing reach in the Toyohira River alluvial fan, Ja...

[1] Several dozen distinct alluvial fans, 10 to 40 km long downslope, have been observed in highlands craters. Within a search region between 0 and 30 S, alluvial fan-containing craters were found only between 18 and 29 S, and they all occur at around ±1 km of the MOLA-defined Martian datum. Within the study area they are not randomly distributed but instead form three distinct clusters. Fans t...

Gently sloping surfaces for settlement are scarce in high mountains ranges and they are commonly related to distal parts of alluvial fans where floods hazards can be expected. To understanding the influence of external factors, such as climatic variability and land uses, on the alluvial fan accretion and flooding processes, sedimentology and pollen analysis from local site provide valuable data...

Francesco Comiti) had the following objectives included in the Workpackage WP1 "Development of functional relationships for debris flow behaviour" and WP3 " Development of a small basin debris flow impact model": • Organisation of the research team and scientific coordination of activities • Acquisition of existing data on debris flow characteristics in small basins located in the Veneto Region...

introduction: playa is one of the most important landscapes in arid regions which covers about 1% of the world's total land area. study of playas is important from different points of view especially pedology, sedimentology, mineralogy, environmental geology, groundwater and surface water chemistry. more than 60 playas have been identified in iran. considering the fact that playas and surroundi...
