  1. 1. Modeling rating curves from close-range remote sensing data : Application of laser and acoustic ranging instruments for capturing stream channel topography

    Författare :Norris Lam; Steve W. Lyon; Jason W. Kean; Ida Westerberg; Helle Skånes; James Brasington; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; laser scanning; acoustic Doppler current profiler; hydraulic modeling; rating curves; Sweden; Physical Geography; naturgeografi;

    Sammanfattning : A rating curve provides a functional relationship between water height (i.e. stage) and discharge at a specified cross-section in a river. Used in combination with a time series of stage, rating curves become one of the central components for generating continuous records of streamflow. LÄS MER

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

    Författare :Ida Westerberg; Sven Halldin; Jan Seibert; Lars-Christer Lundin; Chong-Yu Xu; Deliang Chen; Alberto Montanari; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. Towards better practices in detection of wastewater pollution in stormwater sewers and volume estimation of SSO discharges

    Författare :Oleksandr Panasiuk; Sveinung Sægrov; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Separate sewerage systems are designed so that the wastewater and stormwater are carried separately. However, in practice, untreated wastewater discharges to receiving waters are not that rare, impairing the quality of the receiving waters and increasing the risks to public health and aquatic organisms.

  5. 5. The assisting hand assessment : continued development, psychometrics and longitudinal use

    Författare :Marie Holmefur; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Assisting Hand Assessment; measurement; hand function; children; unilateral cerebral palsy; hemiplegia; longitudinal; psychometrics; Rasch analysis;

    Sammanfattning : For most people, using both hands together is a natural part of everyday activities. But for children with a unilateral disability in the arm and hand, activities requiring two hands are often a challenge. In order to evaluate interventions that optimize the use of the affected or assisting hand, valid and reliable measures are needed. LÄS MER
