En fallstudie om skyfallsskador på riksväg 90 i Kramfors kommun
… society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to …
Jämförelse mellan fällning (FeCl<sub>3</sub> och Al<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>), membranfiltrering och jonbyte med MIEX<sup>®</sup>
Halten löst organiskt material (DOC) har under de senaste 20 åren ökat i våra sjöar. Det har också skett förändringar i karaktären. DOC ställer till problem för vattenverk som använder ytvatten som dricksvattenkälla genom att det kan ge lukt, smak och färg till vattnet. Det ger …
Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium …
… The correlations reported seasonal climate in terms of average temperature and precipitation versus trap catches. The study will not examine the biotic factors affecting bark beetle reproductive success.
hot mot grundvattnets kvalitet och kvantitet?
… to the inflow from Gavleån there is also a natural groundwater recharge from precipitation surplus and artificial infiltration of surface water from Gavleån pumped up to a infiltration pond where the water then is infiltrated into the ground. The groundwater from the esker …
En studie kring hotet mot Åre kommuns vinterturism och dess anpassning till framtida klimatförändringar
… around A’re will increase gradually during this time interval. The precipitation is also expected to increase which could lead to more snow in the area. In a short term A’re may favour the climate changes while ski resorts in the Alps and southern Sweden may be affected more by …
Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar
… %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come. The conclusions from this …
Nederbördsmätning är viktigt inom många områden och en relativt ny teknik är enoptisk distrometer som med hjälp av laserteknik mäter nederbördspartiklarnasdroppstorlek och fallhastighet. Syftet med detta arbete var att undersöka hur välThies distrometer stämmer överens med …
This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The …
… concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new …
Chemical stabilization of mine waste with sewage sludge and calcium carbonate residues
… minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically …
