Abstract

In this research, the catchment area of the Karkheh River has been investigated in order to investigate the relationship between the sediment and the effect of climate change on the phenomenon of microstrip. In the first step, to determine the relationship between the grains and sediments, it is necessary to determine the origin of sedimentation and its gradation. Accordingly, some sediment samples were taken from the river bed. Sediment aggregate size measurement is an important tool for studying its origin. Currently, for statistical purposes, many samples are used, but these methods are time-consuming and difficult. The size of the sediment in the study of origin, and its relationship with the micro-organisms, is an important factor. Therefore, the use of modern methods is essential. In the present study, the data of the sediment samples were introduced into the acetate gradient (statistical analysis program) to determine the texture and granulation of the sediment. The results showed that sand gravel texture is. Then sampling and testing on the microscopes showed that they are also of sandy origin, so it can be assumed that abrupt grafting of microspheres after sediment can cause sediment in the river. In addition, in order to investigate the effect of climate change on the micrographs, the relationship between three climatic parameters including rainfall, minima and relative humidity with the number of days with a rigorous refreshment for two years of 2015 and 2016 were analyzed. The results showed that, with increasing temperature and decreasing precipitation and relative humidity, the number of days with the coarse cutter increases, and as a result, it can be caused by sedimentation as part of sedimentation in the river.
研究沙尘与沉积物之间的关系,评估气候变化对沙尘的影响并提供适应措施
本文以喀尔喀河流域为研究对象,探讨了气候变化对微带现象的影响与泥沙的关系。第一步,要确定颗粒与沉积物的关系,必须确定沉积的起源及其级配。因此,从河床上取了一些沉积物样本。泥沙团聚体粒度测量是研究其成因的重要工具。目前,为了统计目的,使用了许多样本,但这些方法既耗时又困难。沉积物的大小及其与微生物的关系是研究沉积物起源的一个重要因素。因此,使用现代方法是必不可少的。在本研究中,将沉积物样品的数据引入醋酸盐梯度(统计分析程序)来确定沉积物的质地和颗粒。结果表明:砂砾的纹理为。然后在显微镜下取样和测试表明它们也是砂质来源,因此可以假设微球在沉积后突然嫁接是导致河流沉积的原因。此外,为了研究气候变化对显微照片的影响,分析了2015年和2016年2年的降雨量、最小值和相对湿度3个气候参数与严格休整天数的关系。结果表明,随着温度的升高,降水和相对湿度的减少,粗刀出现的天数增加,这可能是河流沉积的一部分,是由沉积引起的。
