Alluvial fans in southern Monglia occur along a group of narrow discontinuous mountain ranges which formed as transpressional uplifts along a series of strike-slip faults. They provide information on the nature of neotectonic activity in the eastern Gobi Altai range and on palaeoclimate change. Alluvial fan formation was dominated by various geomorphological processes largely controlled by clim...

abstract geomorphology and soil genesis and its development are closely related. besides, soil-landscape studies provide a better understanding of soil forming processes. the objectives of the present research include soil genesis studies, micromorphology and clay mineralogy of soils related to geomorphic surfaces in jiroft area. soil temperature and moisture regimes of the area are hyperthermi...

seismic waves are filtered as they pass through soil layers, from bedrock to surface. frequencies and amplitudes of the response wave are affected due to this filtration effect and this will result in different ground motion characteristics. therefore, it is important to consider the impact of the soil properties on the evaluation of earthquake ground motions for the design of structures. soil ...

Mars' transition from an early "warm and wet" to the "cold dry" environment left fingerprints on geological record of fluvial activity Mars. The morphological mineralogical observations aqueous provided varying constraints condition duration liquid water martian surface. In this study, we surveyed mineralogy alluvial fans deltas investigated hydrated silica-bearing deposits associated with thes...

The Quchan fault is located in Quchan - Shirvan area which is a part of Chenaran- Bojnourd plain in Kopeh-Dagh zone, NE Iran. The Quchan active fault with northwest – southeast trending is one of the most important strike-slip faults in the area which its activity led to the numerous historical and instrumental earthquakes. The Neo-tectonic activities of this fault are investigated by the drain...

Abstract Given the substantial groundwater level declines in Central Valley of California, there is an urgent need to supplement recharge systems by implementing managed aquifer recharge. With approximately 170 km 3 (140 million acre-feet) available storage space, water deemed be excess during wet years could spread on ground surface at selected locations allowing it move downward underlying sy...
