Numerous studies have investigated future changes in extreme precipitation by employing climate models. However, trends short-duration (20–180 min) rainfall intensities, that is, design storm intensities used for stormwater infrastructure design, received considerably less attention despite their importance. This study quantified the effect of change on intensity based observations. Trends were diverse short-term durations, ranging from 20 to 180 min, at 11 meteorological stations Northern...
Biomass is defined as organic matter from living organisms represented in all kingdoms. It recognized to be an excellent source of proteins, polysaccharides and lipids and, such, embodies a tailored feedstock for new products processes apply green industries. The industrial focused on the valorization terrestrial biomass are well established, but marine sources still represent untapped resource. Oceans seas occupy over 70% Earth’s surface used intensively worldwide economies through fishery...
Implementation of construction works on weak (e.g., compressible, collapsible, expansive) soils such as peatlands often is limited by logistics equipment and shortage available applicable materials. If preloading or floating roads geogrid reinforcement piled embankments cannot be implemented, then soil stabilization needed. Sustainable in an environmentally friendly way recommended instead applying known conventional methods pure cementing excavation a single replacement soils. Substitution...
Abstract. Time series of monthly, seasonal and annual mean air temperature, precipitation, snow cover duration specific runoff rivers in Estonia are analysed for detecting trends regime shifts during 1951–2015. Trend analysis is realised using the Mann–Kendall test detected with Rodionov (sequential t-test shifts). The results from related to time indices large-scale atmospheric circulation. Annual temperature has significantly increased at all 12 stations by 0.3–0.4 K decade−1. warming...
The main components of landfill gas are methane and carbon dioxide. Emissions methane, a strong greenhouse gas, can be minimized by in situ oxidation the bioactive cover layer. Typically, organic-rich porous materials such as compost used for this process. In study, material biocover was obtained from same mining. objective to study spatial distribution gases efficiency degradation biocover. dioxide emissions were measured at 29 measuring points six times on surface once depth 0.5 m. highest...
Industrial and strategic significance of platinum group elements (PGEs)—Os, Ir, Ru, Rh, Pd, Pt—makes them irreplaceable; furthermore, some PGEs are used by investors as “safe heaven” assets traded in the commodity markets. This review analyzes from various aspects: their place geosphere, destiny anthroposphere, opportunity economy considering interactions among exploration, recycling urban ores, trade markets, speculative rhetoric, changes required for successful technological progress...
The urbanization and increasing growth of planet's population accumulates significant volume disposed waste as well increases risks on human health environmental safety.Landfill systems are the dynamic, living in space time, potentially harmful entities that must be managed careful smart way possible.There many studies related to landfill emissions such leachates methane.However, there is a need for advanced understanding hydrological regime climate change associated changes cycle.The...
Climate change in recent decades has been identified as a significant threat to natural environments and human wellbeing. This is because some of the contemporary changes climate are abrupt result persistent state systems; so called regime shifts (RS). study aimed detect analyse timing strength RS Estonian at half-century scale (1966−2013). We demonstrate that extensive winter warming Northern Hemisphere late 1980s was represented atmospheric, terrestrial, freshwater marine systems an extent...
Climate change is altering temperature, precipitation, and other climatic parameters, affecting sectors dependent on water resources, e.g. energy production. The purpose of this study to analyze the possible influences climate hydropower potential in North Estonia. In Estonian run-of-river plants, comes mainly from volume. Thus, changes production are related river runoff. Soil Water Assessment Tool (SWAT) model used runoff responses Kunda, Keila Valgejõe basins. A sequential uncertainty...
Phosphorus (P) is one of the nutrients causing eutrophication in many our waterways. In present study, we investigated Sachtofer PR Ca-Fe oxide granules as a potential P sorption material (PSM) for constructed wetlands. We found with various experiments follows: 24 h batch experiment highest initial concentration 50 mgP L−1 yielded 0.48 g−1 removal per mass unit, kinetic 600 duration 1.25 g−1, maximum phosphorus adsorption capacity estimated from Langmuir equation 23.78 and long term...
Due to the harmful effect on environment, landfill gas has be collected and processed. One possible solution would covering with a bioactive layer, where methane is oxidized.
 The aim of this research study possibilities extracting material for degradation layer from itself by means Landfill Mining (LFM). Chemical biological properties as well hydrophysical like hydraulic conductivity saturated volumetric water content fine fraction were measured verify whether meets requirements.

Abstract Global change-type droughts will become more frequent in the future and threaten forest ecosystems around globe. A large proportion of Estonian sector is currently subject to artificial drainage, which could probably lead negative feedbacks when water supply falls short because high temperatures low precipitation during drought periods. In this article, we propose a novel research perspective that make use already gathered data resources, such as remote sensing, climate data,...
Summary Emissions of greenhouse gasses (GHG) and particularly methane have strong negative effects on global atmospheric carbon balance climate change. The emissions from the waste sector are about 18 % global, however large unexplored pools unwanted might come industrial brownfields as former coal oil shale quarries,, hydraulic fracturing potential fluid leakage zones, acid tar ponds more. After landfill or industry site is closed, gas still active in landfills has to be collected until...
