Conceptual and numerical models of the evolution of pedogenic carbonates in soils of arid and semi-arid regions: A review
Introduction Calcareous soils are widely distributed in arid and semi-arid regions of the world and the presence of carbonates in the soils affects both physicochemical properties and the pedogenic evolution. In addition, soil carbon plays a critical role in the global carbon cycle, and pedogenic carbonates are an important sink for atmospheric carbon. Pedogenic carbonates are also the proxy o...
متن کاملInvestigating the interaction between rivers and sand dunes in arid and semi-arid regions of Iran
Extended abstract 1- Introduction Fluvial and aeolian processes are important factors in changing the surface of morphology in the Earth. When rivers and sand dunes meet, the transportation of sediment between them can lead to one of the systems or both of them change. With their connection between river sediment and wind systems there would be lots of reactions, but very little has been st...
متن کاملTrend analysis and detection of precipitation fluctuations in arid and semi-arid regions
The most important impacts of climate change relate to temperature and precipitation. Precipitation is particularly important, because changes in precipitation patterns may lead to floods or droughts in different areas. Also, precipitation is a major factor in agriculture and in recent years interest has increased in learning about precipitation variability for periods of months to annual and s...
متن کاملThe Landscape as a Unit for Rangeland Inventory in Arid and Semi-arid Regions of Iran
Severe range degradation was critically extended in many region of Iran and caused many rangelands were restricted and interwoven with croplands in a complex system. Therefore, rangeland planning and inventory as an isolated activity has become almost impossible. Current landscape planning involves contributions of different social organizations often with different interests and with different...
متن کاملWind and Water Erosion in Semi-arid Ecosystems
Soil erosion is an important process in dryland ecosystems, yet measurements and comparisons of wind and water erosion within and among such ecosystems are lacking. Here we compare wind erosion and transport field measurements with water erosion and transport from rainfall-simulation for three different semi-arid ecosystems: a shrubland near Carlsbad, New Mexico; a grassland near Denver, Colora...
