Sand flux estimation during a sand-dust storm at Tazhong area of Taklimakan Desert, China

Sand Flux Simulations at a Small Scale over a Heterogeneous Mesquite Area of the Northern Chihuahuan Desert

Within areas of the Chihuahuan Desert dominated by honey mesquite bushes (Prosopis glandulosa), soil erosion causes open eroded patches and the formation of large coppice dunes. The airflow patterns around the dunes and through the open areas are correlated with sand flux and erosion. This study uses wind velocity simulations from the Quick Urban and Industrial Complex (QUIC) model in combinati...

New Method for Estimation of Aeolian Sand Transport Rate Using Ceramic Sand Flux Sensor (UD-101)

In this study, a new method for the estimation of aeolian sand transport rate was developed; the method employs a ceramic sand flux sensor (UD-101). UD-101 detects wind-blown sand impacting on its surface. The method was devised by considering the results of wind tunnel experiments that were performed using a vertical sediment trap and the UD-101. Field measurements to evaluate the estimation a...

Surface observation of sand and dust storm in East Asia and its application in CUACE/Dust

A Study on Dust Storms Using Wind Rose, Storm Rose and Sand Rose (Case Study: Tehran Province)

Sand and dust storms are natural events that occur widely around the world, mostly in dry and bare lands. Over thepast decade a large part of Iran has been affected by this phenomenon, and Tehran has not been excluded from thisevent. Therefore, having knowledge of spatiotemporal frequency variations can aid us in future management andstorm trajectory assessment. In this study the synoptic anemo...

Radioactive analysis and radiological hazards of sand in Weifang, China

Background: The activity concentrations of 226Ra, 232Th and 40K in sand used as building material in Weifang of China were investigated for evaluating the radiation hazard. Materials and Methods: Sand samples were collected from Weifang and their radioactivity levels were measured using gamma-ray spectrometry. The radiation hazard for residents was assessed by radium equivalent activity (Raeq),...
