“…The model's consistency depends on whether or not model matches reality of things then the theoretical model would be appropriate (Roy et al, 2020a). The ROC is the most accurate tool used for estimating the precision of the expected circumstance in different fields (Roy et al, 2020c). This method is used to determine the precision in different predicated models; frequency ratio, GWR, support vector machine, entropy model, advanced decision tree, analytical hierarchy process etc.…”

The large-scale water-induced erosion is one of the most determining elements on land degradation in subtropical monsoon-dominated region. From this large-scale erosion, the fertility of the agricultural land has been decline consequently. So, estimation of the amount of erosion and its accurate prediction is necessary for escaping from this hazardous situation. In this study, the application of evidential belief function (EBF), spatial logistic regression (SLR) and ensemble of EBF and SLR to estimate the erosion potentiality with the help of ArcGIS and Soil and water assessment tool (SWAT). The average annual soil erosion has been estimated with the help of revised universal soil loss equation (RUSLE) and geographical information system (GIS). Apart from this to evaluate the importance of morphotectonic parameters on soil erosion, the correlation between erosion potentiality and average annual soil erosion has been quantified. In large-scale erosion, there is a direct impact of storm rainfall event in monsoon period in the entire subtropical region. Here, in erosion potentiality assessment, the optimal capacity of ensemble EBF-SLR is higher than the single alone methods, i.e., EBF and SLR. So, the mentioned approaches can be applied in soil erosion research in subtropical environment with considering the erosion causal parameters. This type of information can be helpful to the decision-maker and stakeholders to take proper initiative to reducing the rate of erosion. The main task of the future researcher is to implement this method more accurate ways with considering more reliable variables and slight modifications of the approaches in keeping in the view of regional environment.

“…The occurrence and distribution of flash floods are controlled by rainfall, which is the main trigger factor, and associated with short, high-intensity rain (Borga et al, 2010). The heavy rainfall over a short period causes quick-rising flash floods, which is very common (Roy et al, 2020). The contribution of convective precipitation was about 50% for 75% of the flash floods, and it increases to 70% for 50% of them (Llasat et al, 2016).…”

“…Land-use and climate change are often referred to as 'global change' (Lopez-Tarazon et al, 2019), are two of the most critical drivers of hydrological variations (Kim et al, 2013;Kundu et al, 2017), affecting the formation and development of flash floods due to a complex interaction of the water-vegetation-soil system (Swain et al, 2021;Wang et al, 2020;Zhang et al, 2018). The weather system is becoming more and more unstable under climate change, increasing extreme weather events (Roy et al, 2020;Yu et al, 2018a). One of the main impacts appears to increase the frequency and magnitude of extreme rainfall events (Allan and Soden, 2008;Barredo, 2006;Debortoli et al, 2017;Li et al, 2021;Llasat et al, 2021).…”

Understanding the spatiotemporal characteristic of flash floods is significant for the reasonable and accurate identification of high-risk regions of disasters as well as future prediction of hydrological regimes. Therefore, this study collected time-series datasets (1979-2015) of historical flash flood events, rainfall, and land-use in the Hengduan Mountains region, China to characterize the spatiotemporal variation in flash floods affected by the change in rainfall and land-use. Using linear trend, a significant increase with 12 times/10a for flash flood events was found while 82% of events occurred in the flood season (June–August). They were closely related to the increase in frequency (3.5 d/10a) and magnitude (215.55 mm/10a) of heavy rainfall as well as the amplified artificial (999 km2). Affected by heavy rainfall due to climate change and human activity, significant periodic variations on the scales of 3-7a, 8-15a, and 21-31a were derived based on the Morlet wavelet analysis. Meanwhile, utilizing the standard elliptical difference, we identified the moving route of the gravity center of flash floods, with the direction from northwest to southeast. More recorded disasters generally were found in the south of the Hengduan Mountain region, where was mainly controlled by frequent rainstorms and the formation of more cropland and artificial with higher runoff potential. These findings can be an appropriate supplement for lack of understanding of the spatiotemporal dynamics of flash floods in the Hengduan Mountains region and could provide policymakers with evidence to identify high-risk areas which is difficult to cope with in the mountainous watershed.

“…Due to the excessive consumption of natural resources and the increase of carbon emissions, global climate change is becoming more and more obvious. Extreme severe weather conditions such as high temperature and flood frequently occur [4][5][6]. At the same time, the urban surface is covered by a dense concrete structure, which blocks the flow of water and gas between underground and ground, causing many urban problems, such as urban waterlogging, groundwater recession, noise pollution, and urban heat island phenomenon [7][8][9][10].…”

The waste crumb rubber (WCR) and silica fume (SF), as industrial waste and byproduct, are widely used as additives in road construction materials, which can not only realize waste utilization and protect the environment but also reduce the consumption of building material resources. At present, most of the research has focused on the properties of concrete modified only by WCR or SF; there are few studies concentrated on composite modified concrete by the two, especially the study on pervious concrete (PC). This article aims to study the mechanical strength, deformability, and freeze-thaw (F-T) resistance of waste crumb rubber/silica fume composite modified pervious concrete (RSFPC). The RSFPC and control specimens were manufactured in the lab. The experiments of compressive strength, flexural strength, flexural failure strain, flexural elastic modulus, and F-T cycles were conducted. In addition, the properties of RSFPC were compared with WCR and SF single modification PC. The results indicate that the composite modification of WCR and SF can give full play to the advantages of the two materials so that the strength property and elastic modulus of PC will not be decreased and the F-T resistance and deformability can be greatly improved. Compared to a single modification group by WCR or SF, RSFPC has a more balanced and comprehensive performance, which will greatly expand the application of PC.
