İlk kez 1913 yılında de Martonne tarafından kullanılan Klimatik Jeomorfoloji kavramı 20. yüzyılınbaşlarından itibaren birçok ülkede benimsenmiş ve pek çok kişi konuyla ilgili sayısızçalışmalar yapılmıştır. Yer şekillerinin oluşumunda, gelişiminde dağılışında iklimin öneminevurgu yapan söz konusu yaklaşım, başlangıçta W.M.Davis’in fikirleri çalışmaları etrafında şekillenmiştir.Bu dönemde araştır...

The paper is focused on Digital Elevation Model (DEM) reconstruction from differential interferometry synthetic aperture radar (DInSAR). In doing so, conventional DInSAR procedures are implemented to three repeat passes of RADARSAT-1 SAR fine mode data (F1). Further, the multichannel MAP height estimator is implemented with phase unwrapping technique. Consequently, the multichannel MAP height e...

Figure 11 Average depth of magma lens reflections beneath ridges versus spreading rate. The curved line shows the depth to the 12003C isotherm calculated from the ridge thermal model of Phipps Morgan J and Chen YJ (1993) Journal of Geophysical Research 98: 6283}6297. Data from different ridges are labeled Reykjanes Ridge (RR), Juan de Fuca Ridge (JdF), Costa Rica Rift (CRR), Lau Basin (Lau), no...

Future global warming has a number of implications for fluvial geomorphology because of changes in such phenomena as rates of evapotranspiration, precipitation characteristics, plant distributions, plant stomatal closure, sea levels, glacier and permafrost melting, and human responses. Potential changes in rivers are outlined in this review in the context of changes in the intensity of rainfall...

This paper presents a geomorphological map of the Hérens valley in the Western Swiss Alps. With an area of 270 km and altitudes ranging from 470 to 4357 m a.s.l., this valley is one of the main secondary catchments of the Upper Rhône valley. The high differences in altitudes, combined with a varied geology, create an important geomorphic diversity. The main processes active in mountain areas, t...

Martian terrains are represented as a series of drainage basins, regardless of the historical presence or absence of actual fluid flow. A statistical analysis of each drainage network, computationally extracted from an underlying topography based on the MOLA data, yields a network descriptor, a compact, numerical characterization of a network. These descriptors are used to compare different mar...

Nowadays, desertification is one of the ecological crises of the world. To control Desertification, having a clear understanding of its factors and processes is necessary. KALMAND Protected Area region of Yazd with area of 71269.37 Hectares’ was considered to evaluate current Condition of desertification using ICD. Iranian Classification of Desertification (ICD) was presented by M. Ekhtes...

Normal faulting earthquakes play an important role in the deformation of continents, and pose significant seismic hazard, yet important questions remain about their mechanics. We use InSAR and bodywave seismology to compute dislocation models and centroid moment solutions for four normal-faulting earthquakes (Mw 5.7–6.2) that occurred in the Pumqu-Xainza Rift (PXR), southern Tibet, a region whe...
