Long-term records of nitrogen in deposition and streamwater were analysed at 30 sites covering major acid sensitive regions in Europe. Large regions of Europe have received high inputs of inorganic nitrogen for the past 20-30 years, with an approximate 20% decline in central and northern Europe during the late 1990s. Nitrate concentrations in streamwaters are related to the amount of N depositi...

abstract pedotransfer functions (ptfs) are useful means of prediction many properties of the soil, and especially the hydraulic characteristics of this porous media. the main advantages of this functions, as compare to conventional methods used to directly estimate soil hydraulic properties, is that they are not time-cost consuming. different approaches such as classic linear and non linear reg...

In this conference contribution, we present and discuss the results for capillary cohesion of different granular materials determined through approaches. First, consider macroscopic uniaxial compression tests with varying degrees saturation. Second, derive theoretical from water retention curve (WRC) measured in experiments. Finally, is calculated air-water interfacial areas solid-water extract...

in this research, a 2d laterally averaged model of hydrodynamics and water quality, ce-qual-w2, was applied to simulate water quality parameters in the ilam reservoir. the water quality of ilam reservoir was obtained between mesotrophic and eutrophic based on the measured data including chlorophyll a, total phosphorus and subsurface oxygen saturation. the ce-qual-w2 model was calibrated and ver...

Salt marshes are among the most productive ecosystems in the world, performing important ecosystem functions, particularly nutrient recycling. In this study, a comparison is made between Mondego and Tagus estuaries in relation to the role of Spartina maritima in nitrogen retention capacity and cycling. Two mono-specific S. maritima stands per estuary were studied during 1yr (biomass, nitrogen (...

Whether you're experiencing abdominal bloating, excess gas, or the burping blues, there are many possible causes of your discomfort. Water retention, also known as edema, is an accumulation of extra fluid that?s commonly caused by a temporary imbalance in your electrolyte [2] and fluid levels. While you're right that a diet high in sodium may lead to bloating, it's not the only cause. It could ...

Besides nutrient composition, the hydraulic performance of horticultural substrates is a main issue for evaluating their quality for horticultural purposes. Their water and air capacity and their suitability for transporting water are important hydraulic quality indicators. Shrinkage and water repellency could have a negative impact on storing and transporting water and solutes. The commonly us...
