Prevention of Wind Erosion in Salty Lands of Urmia Lake with Butadiene Carboxylic Latex and Cement Grout

Abstract

Known as one of the serious environmental problems, wind erosion can affect infrastructures, agricultural lands, human health and may create political problems between nations. By changing the climate in recent years and due to wind blowing in the area, the salt storms are generated in nearby salt lands. In this experimental study, the effectiveness of butadiene carboxylic latex emulsion and cement grout in preventing wind erosion in Urmia Lake region was investigated. The stabilized samples' resistance to wind erosion in an open-loop low-speed wind tunnel have been modeled based on the specific critical situation of study area (wind velocity of 30 m.s(-1)). The erosion rate decreased with the increment in the amount of cement grout sprayed on salt samples. Wind erosion rate decreased with increasing Butadiene carboxylic latex content in salt samples stabilized with butadiene carboxylic latex. It was observed that Butadiene carboxylic latex is more effective than cement grout in stabilizing salty lands against wind erosion. Wind erosion rate decreased by an average of 95% in stabilization with cement grout and 99% in stabilization with butadiene carboxylic latex. Experimental studies showed that both butadiene carboxylic latex and cement grout can be used to prevent wind erosion in Urmia Lake Salts.
