  1. 11. Seasonal Variations of Manning’s Coefficient Depending on Vegetation Conditions in Tärnsjö, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Rūta Plakane; [2017]
    Keywords : Manning’s roughness coefficient; vegetation; HEC-RAS; Tärnsjö; uncertainty; rating curve; Manning råhetskoefficient; vegetation; HEC-RAS; Tärnsjö; osäkerhet; ratingkurva;

    Abstract : Hydrological models are used widely and they demand for multiple input variables and observations. One of those variables is Manning’s roughness coefficient. In the current literature the variability of the coefficient poses an unknown uncertainty. READ MORE

  3. 12. A Hydrological Model of the Mundaú River Basin, Recalibration of a MGB-IPH rainfall-runoff model using updated land-use data

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Michael Cockrell; [2016]
    Keywords : Rainfall runoff modeling; MGB-IPH; Mundaú; Brazil; Water allocation grants; ANA; Technology and Engineering;

    Abstract : Avrinningsområdet Mundaú har sitt ursprung i den Brasilianska delstaten Pernambuco och rinner i sydöstlig riktning mot Mundaúlagunen längs Atlantkusten tillhörande delstaten Alagoas. Området faller under nationell jurisdiktion, är relativt oreglerat och erfar både översvämningar och torrperioder. READ MORE

  4. 13. Modelling Hydrological Impacts of Forest Clearcutting through Parameter Regionalization

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Benjamin Selling; [2015]
    Keywords : Rainfall-runoff modeling; Forest clear cut; HBV model; Parameter regionalization; Impact assessment; Hydrologisk modellering; Skogsavverkning; HBV modellen; Parameterregionalisering; konsekvensanalys;

    Abstract : The aim of this thesis was to test and evaluate whether parameter regionalization of a hydrological model can be used to model the impact of forest clearcutting on streamflow in Sweden. This is an important task to be able to perform water management and impact assessments adequately. READ MORE

  5. 14. Regional Quantification of Climatic and Anthropogenic Impacts on Streamflows in Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sofia Hedberg; [2015]
    Keywords : Rainfall-runoff modeling; Change point and trend detection; time- series analysis; attribution of changes; climatic and anthropogenic impact; HBV- model; Hydrologisk modellering; detektion av trender och abrupta förändringar; tidsserieanalys; orsakskoppling till förändringar; klimat och antropogen påverkan; HBV modellen;

    Abstract : The anthropogenic impact on earth’s systems has rapidly increased since the middle of the last century and today it is hard to find a stream that is not influenced by human activities. The understanding of causes to changes is an important knowledge for future water management and planning and of that reason climatic and anthropogenic impact on streamflow changes in Sweden were explored and quantified.

  6. 15. Hydrological Modelling of Al Auja Earth Dam in the Lower Jordan Valley.

    University essay from KTH/Mark- och vattenteknik

    Author : Otto Rimfors; Vadim Velichkin; [2015]
    Keywords : Hydrological modelling; arid areas; Jordan Valley; water scarcity; Al Auja; HEC-HMS; SMA; CN;

    Abstract : In a populated region with very high potential evapotranspiration, where the rainwater falls only during the winter and mostly in the mountains, the need for sustainable water management and fair distribution is crucial. In the West Bank, Palestine, the main potable water source is a karst mountain aquifer system. READ MORE
