Monolithic waste materials (e.g. Portland cement treated wastes) in many field scenarios do not remain continuously saturated, but experience intermittent wetting interspersed with periods of storage in an unsaturated environment. During storage, the matrix may loss moisture to the environment, promoting precipitation or redistribution of species. In addition, the matrix may react with the surr...

A hot and acid crater lake is located in the Nakadake crater, Aso volcano, Japan. The volume of water in the lake decreases with increasing activity, drying out prior to the magmatic eruptions. Salt-rich materials of various shapes were observed, falling from the volcanic plume during the active periods. In May 2011, salt flakes fell from the gas plume emitted from an intense fumarole when the ...

Climate change is altering the water cycle globally, increasing frequency and magnitude of floods droughts. An outstanding question whether biodiversity responses to hydrological disturbance depend on background climatic context – if so, which contexts increase vulnerability disturbance. Answering this requires comparison organismal across environmental gradients. However, opportunities track d...

Numerical simulations were carried out for moist, porous media, intermittent microwave convective drying (IMCD) using a multiphase flow model in media subdomains coupled with forced-convection heat-transfer an external hot air subdomain. The models solved by COMSOL Multiphysics was applied at the pulse ratio (PR) of 3. Based on characteristics and distribution evaporation interface, IMCD compar...

Key questions dominating contemporary ecological research and management concern interactions between biodiversity, ecosystem processes, and ecosystem services provision in the face of global change. This is particularly salient for freshwater biodiversity and in the context of river drying and flow-regime change. Rivers that stop flowing and dry, herein intermittent rivers, are globally preval...

Red spruce (Picea rubens Sarg.) seedlings were exposed repeatedly at a field site or in a greenhouse~to acidic mist containing the major sulfur and nitrogen pollutants of wet deposition in the eastern U.S.: sulfate alone, nitrate alone or with ammonium ion, and a combination of these ions. Acidities and ion concentrations ranged from below the mean to above the maximum concentration for cloudwa...

Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Climate change induced drying and flooding may alter the redox conditions of organic matter decomposition in peat soils. The seasonal and intermittent changes in pore water solutes (NO − 3 , Fe 2+ , SO 2− 4 , H ...

Abstract Because of global change and increasing anthropogenic pressures, non‐perennial rivers streams are predicted to drastically increase in the European‐Mediterranean region. Some river basins already subject reduced levels available superficial flow may present a further reduction, with significant intermittence phenomena complete drought former perennial rivers. In this context, sound kno...

Intermittent rivers and ephemeral streams (IRES) compose the majority of draining networks on Earth, supporting a unique fraction biodiversity. Despite their high ecological value, IRES are increasingly threatened by global change require appropriate biomonitoring restoration tools. However, indices indicators used in routine programs often confounded drying effects. This occurs because most po...
