  1. 1. Observational Uncertainties in Water-Resources Modelling in Central America : Methods for Uncertainty Estimation and Model Evaluation

    Author : Ida Westerberg; Sven Halldin; Jan Seibert; Lars-Christer Lundin; Chong-Yu Xu; Deliang Chen; Alberto Montanari; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; Hydrology; Hydrologi; Hydrology; Hydrologi;

    Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE

  2. 2. Hydrological modeling as a tool for sustainable water resources management: a case study of the Awash River Basin

    Author : Selome M. Tessema; Berit Balfors; Ulla Mörtberg; Shimelis Gebriye Setegn; Steve W. Lyon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrological characteristics; Distributed hydrological modeling; Rainfall-runoff correlation; Streamflow prediction; Sustainable water management; Awash River Basin; Hydrology; Hydrologi;

    Abstract : The growing pressure on the world‘s fresh water resources is enforced by population growth that leads to conflicts between demands for different purposes. A main concern on water use is the conflict between the environment and other purposes like hydropower, irrigation for agriculture and domestic and industry water supply, where total flows are diverted without releasing water for ecological conservation.

  3. 3. Macroalgal community dynamics on coral reefs : Implications for management

    Author : Erik Mörk; Nils Kautsky; Magnus Nyström; Tim R. McClanahan; Stein Fredriksen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral Reefs; Herbivory; Nutrients; Ecosystem change; Fish; Sea Urchins; East Africa; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Although rather inconspicuous on healthy coral reefs, macroalgae form the basis of coral food webs. Today, macroalgae are generally increasing and many reefs undergo transitions from coral to macroalgal dominance resulting from e.g. enhanced nutrient loading or increased fishing. READ MORE

  4. 4. Energy Auditing and Efficiency in a Chain Hotel : the Case of Scandic, Järva Krog

    Author : Branko Simanic; Björn Palm; Folke Björk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial engineering and economy; Industriell teknik och ekonomi;

    Abstract :   Energy efficiency and conservation measures in hotels is an area of research at the Department of Energy Technology, Royal Institute of Technology in Stockholm (KTH), Sweden. As a continuation of the research work, this project was focused on a hotel's resource-use performance, considering both internal and external factors that influence their consumption. READ MORE

  5. 5. Utility Disturbance Management in the Process Industry

    Author : Anna Lindholm; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; utilities; process control; plant-wide disturbances; availability; buffer tanks;

    Abstract : Use of utilities, such as steam and cooling water, is very common at industrial sites. Utilities are often shared between several production areas, and a disturbance in the supply of a utility is therefore likely to affect a large part of the production site, and cause great loss of revenue.
