The purpose of this paper is to develop a multiple linear regression model that describes the pavement’s friction behaviour using a degradation evolution law that also considers the effects of weather, vertical alignment and traffic factors. This study is based on real data obtained from two different highways with an approximate total length of 43 km. These sections present different alignment...

Rainstorm weather systems and storm flood characteristics were studied to explore the relationship between the rainstorm weather system, the type of rainstorm, the cause of the flood and the time of occurrence, and some basic characteristics law of storm floods are summarized in the Second Songhua River Basin (Northeastern China). Then, the periodicity of catastrophic years was identified using...

Using a climate version of a regional atmospheric model, we show that the seasonal evolution of weather is dependent on the initial soil moisture and landscape specification. Coupling this model to a land-surface model, the soil moisture distribution and landscape are shown to cause a significant nonlinear interaction between vegetation growth and precipitation. These results demonstrate that s...

Evapotranspiration (ET) is an important component of the hydrologic budget because it expresses the exchange of mass and energy between the soil-water-vegetation system and the atmosphere. Prevailing weather conditions influence potential or reference ET through variables such as radiation, temperature, wind, and relativity humidity. In addition to these weather variables, actual ET (ETa) is al...

response to soil compaction associated with soil and crop type, and soil wetness at the time of load application and weather in Central and Eastern Europe are reviewed. The effects of soil compaction on the morphological and anatomical modifications of the roots were shown. The influence of soil compaction on plasticity in root growth and functioning in relation to structural discontinuity is d...

performance of chamomile (matricaria chamomilla l.) was evaluated on twelve transplanting dates that were arranged at 30 days interval; during 2013-2014 on experimental field of wondo genet agricultural research center; using rcbd design with three replications. transplanting time exerted a very highly significant (p<0.0001) influence on plant height, flower yield and essential oil yield; essen...
