Ridged plains are a major geologic unit on Mars and are a predominant unit on the Tharsis Plateau, a region that has undergone uplift, extension, and extensive shield and flood volcanism. These units, probably flood volcanic in origin, are characterized by landforms classed as wrinkle ridges. Wrinkle ridges are interpreted to be folds, resulting from buckling followed by reverse to thrust fault...

the aim of the study is the classification of landform based on elevation, slope, relief and curvature inputs (old method) and topographic position index (tpi) (new method) in the south of bojnoord. the input data for the two methods is a digital elevation model (dem). the results of topographic position index (tpi) model showed that most area of landform were covered by class 5 (plains small) ...

  In northern Kazakhstan and neighbouring parts of the West Siberian Plain of Russia is one of the world’s biggest concentrations of pans. The area has thousands of them. Landsat imagery and Google Earth images indicate their distribution within this semi-arid area and their forms and associated lunette dunes. Many of the pans, most of which are small, wet and shallow, show a characteristic sha...

Abstract Timber harvests with inadequate forestry best management practices (BMPs) can accelerate soil erosion, which has been associated reductions in water quality and site productivity. Previous studies affirm positive effects accrued by harvesting BMPs. However, few document erosion rates masses harvest access network features (e.g., decks, roads, skid trails, stream crossings) across diffe...

The surface of Mercury has been heavily modified by impact cratering and volcanic plains since the initial formation of its lithosphere and crust. As in the case of the Moon, the origin of early plains deposits has been difficult to determine because ponded impact basin ejecta and impact melt deposits can mimic the topography and texture of extrusive volcanic plains. In order to understand bett...

The statistical downscaling tool of a model (SDSM) to generate the future climate piedmont plain area in Hebei Province for 30-year period. Xinji city was selected as typical example this area. crop growth decision support system agrotechnology transfer (DSSAT) adopted estimate changing trends water footprint winter wheat production under conditions, and obtain optimal irrigation scheme an ‘acc...
