2. 6. Spatially Distributed Hydrological Modelling : Wetness Derived from Digital Elevation Models to Estimate Peatland Carbon

   Author : Abdulghani Hasan; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; modelling hydrology; Digital elevation models; LiDAR data; topographic wetness index; GIS; permafrost; Stordalen; peatland;

   Abstract : To study the hydrology of peatlands and explore wetness distribution is difficultmainly due to the complexity of the surface of peatlands, and also due to the presence of permafrost underlain peatlands in the arctic regions. I have chosen the area called Stordalen mire in the arctic region in northern Sweden for my study. READ MORE

4. 7. Modelling Hydrological and Hydrodynamic Processes in Lake Tana Basin, Ethiopia

   Author : Shimelis Gebriye Setegn; Bijan Dargahi; Nicola Fohrer; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Tana; Climate Change; SWAT; Hydrological Modeling; Hydrodynamic; GEMSS; MCE; Streamflow; Sediment yield; Hydrology; Hydrologi; Water engineering; Vattenteknik;

   Abstract : Lake Tana Basin is of significant importance to Ethiopia concerning water resources aspects and the ecological balance of the area. The growing high demands in utilizing the high potentials of water resource of the Lake to its maximal limit, pictures a disturbing future for the Lake. READ MORE

5. 8. Robust Water Balance Modeling with Uncertain Discharge and Precipitation Data : Computational Geometry as a New Tool

   Author : José-Luis Guerrero; Sven Halldin; Stefan Uhlenbrook; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alpha shape; Convex hull; Depth function; Discharge; Hydrological models; Honduras; Model calibration; Parameter-value estimation; Precipitation; Rating curve; Robust; Robustness; Uncertainty estimation; Water resources.; Alfaform; avbördningskurva; djupfunktion; Honduras; hydrologiska modeller; konvext hölje; modellkalibrering; nederbörd; osäkerhetsskattning; parametervärdesskattning; robust; robusthet; vattenföring; vattenresurser; Hydrology; Hydrologi;

   Abstract : Models are important tools for understanding the hydrological processes that govern water transport in the landscape and for prediction at times and places where no observations are available. The degree of trust placed on models, however, should not exceed the quality of the data they are fed with. READ MORE

6. 9. Environmental Modelling : Learning from Uncertainty

   Author : John M. Juston; Per-Erik Jansson; Jens Christian Refsgaard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

   Abstract : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. READ MORE

7. 10. The interplay between atmosphere, hydrology and land use by environmental modelling

   Author : Fabio Pereira; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Land use changes; expansion of sugarcane; hydrological cycle; coupled models;

   Abstract : Interactions between land surface and atmosphere induced by human activities and natural environmental dynamics act on a time scale that varies from seconds to millions of years. It is by exchanging heat, water, energy and carbon that land surface and atmospheric processes are closely interrelated and influence each other in reciprocal ways. READ MORE
