چکیده

We codify previously published means of calculating exposure ages and erosion rates from 10Be and 26Al concentrations in rock surfaces, and present a single complete, straightforward, and internally consistent method that represents currently accepted practices. It is intended to enable geologists, geomorphologists, and paleoclimatologists, who wish to apply cosmogenic-nuclide exposure age or erosion rate measurements to their work, to: a) calculate exposure ages and erosion rates using a standard method; and b) compare previously published exposure ages or erosion rates on a common basis. The method is available online at http://hess.ess.washington.edu/math.

Modeling Past Episodes of Erosion in the Lake Orūmiye (Urmia) Basin: Analogues for Future Landscape Dynamics

During the Holocene Lake Orūmiye has been subjected to significant changes in climate. These have impacted the surround vegetation and runoff, and erosion rates of the surrounding basin. Shifts in seasonal rainfall from winter to summer dominated patterns have resulted in dramatic changes in the Orūmiye Basin’s vegetation cover from grass to shrub dominated communities. The degree of ground sur...

Investigation of a Cold Model of Internally Circulating Fluidized Bed with Draft Tube to be used as a two-Zone Fluidized Bed Reactor

In this research, a cold model of internally circulating fluidized bed is investigated. The aim is to find the effects of some of the operating parameters on the performance of the reactor. Experiments were carried out in a glass column (30 mm i.d. and 25 cm height) with a centrally located draft tube (11 mm i.d. and 5 or 7 cm height). The bed was loaded with white silica particles (dp = 0.15 -...

Comparison of two MPSIAC and MMF models in soil erosion mapping of Ardebil Agh Gouni watershed

Extended abstract 1- Introduction Soil erosion is the most important cause of land degradation and the cause of water loss, soil loss, sedimentation in water resources, and maximum flood intensification (Liu et al., 2019). Models are the most important tools for estimating and mapping of erosion at the watershed level. As the experimental models are dependent on used coefficients and region c...

Investigating the Effect of Land Use and Soil’s Physio-chemical properties on Wind Erosion Threshold Velocities via Data Mining

Introduction: Wind erosion is a phenomenon that causes severe environmental changes in arid and semi-arid climates. As surface soil texture is very effective in soil erodibility, identifying soil erodibility index is important and efficient. Mismanagement greatly contributes to the development of wind erosion. The velocity that makes the first particles of soil move from the surface is called t...

Measurements of iron concentrate stockpile weight, from laser mapping to investigation of effective parameters on surface density

Determination of stockpile weight and stockpile inventory are critical to any quarry or mining operation, whether it is required by accounting firms or used internally for the quarterly balance of production and sales. Generally, errors and problems originate from two factors. Volume of stockpile that is traditionally worked out from the mapping results has a low accuracy due to irregular shape...
