1. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. LÄS MER
2. Improving stream flow estimation in a montane rainforest stream in Costa Rica : The impact of adding a high flow estimation
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : A key piece of information necessary for water management is accurate streamflow information. However, the available data and resources for gathering information vary around the world. LÄS MER
3. A GIS-Based Method of Deriving Spatially Distributed Unit Hydrographs
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Prior to using hydraulic and spatially distributed modelling softwares, the theory of the unit hydrograph was a commonly used tool for modelling of surface and runoff water. While distributed models often provide detailed results from extensive calculation durations, the unit hydrograph have been questioned for simplifying the physical characteristics of the watershed modelled.

4. Contributions of Event Water to Streamflow in an Agricultural Catchment
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : In agricultural catchments, hydrological processes play an important role in the export of nutrients. Water that enters a catchment during a rain event (event water) can have different flow paths and residence times. LÄS MER
5. Analysis of Hydrometeorological Measurements in Tuy Loan River Basin, Vietnam - A Minor Field Study
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : Bakgrund: De centrala delarna av Vietnam har en årlig nederbörd på 4000 mm/år och det är vanligt med hastigt uppkomna översvämmningar (s.k. flash floods) här. Flash floods är plötsliga översvämmningar med ett högt flöde producerade av kraftiga regn. LÄS MER
