soil erosion is a serious problem especially in northern parts of iran. one themost important side effects on soil erosion may be the decline in qualities of soil refers toagricultural productivity. so it is very important to assess the soil erosion risk for thesustainable development of agriculture. this study outlines ways undertaken to provide anew tool to manage water erosion from physical ...

Live shrubs in forest understories pose a challenge for mitigating wildfire risk with prescribed fire. Factors driving shrub consumption fires are variable and difficult to explain. This study investigated spatial patterns drivers of Sierra Nevada mixed-conifer through analysis high-resolution imagery taken before after We applied spatially explicit, generalized additive model assess tree cover...

Road surface irregularity is known to effect vehicle NVH responses. When modeling vehicle NVH, it is desirable to have high-resolution measurements of the road surface to use as road input. For typical NVH modal tire models, the road surface sampling rate will not be an issue because several points on the tire patch (center line) are used to determine the road surface irregularity. The single p...

The parts of Yogyakarta-Bawen Toll Road Indonesia, based on the geological agency’s liquefaction susceptibility map are located moderately susceptible to soil. This can be a preliminary indication as it roughly indicate potential. However, cannot illustrate actual condition in detail its inputs macro parameters (geological and seismicity factors). existence silty sand sand, earthquake sources, ...

Risk factors are generally defined and assigned to road networks, as constant measures in hazmat routing problems. In fact, they may be dynamic variables depending on traffic volume, weather and road condition, and drivers' behavior. In this research work, risk factors are defined as dynamic variables using the concept of chaos theory. The largest Lyapunov exponent is utilized to determine the ...

BACKGROUND Achieving health benefits while reducing greenhouse gas emissions from transport offers a potential policy win-win; the magnitude of potential benefits, however, is likely to vary. This study uses an Integrated Transport and Health Impact Modelling tool (ITHIM) to evaluate the health and environmental impacts of high walking and cycling transport scenarios for English and Welsh urban...

road traffic accidents and the effects they subsequently incur are increasing dramatically, and estimating the cost of road traffic crashes could be a vital step in improving the recognition of this widespread problem. the main objective of this paper is to estimate the cost of road traffic crashes in iran using the human capital (hc) method. results of this study indicate that the cost of road...
