LOTTA ANDERSSON

My main research interest is towards catchment modelling of spatial and temporal variability of water flow and nutrients due to natural variability and human impact, with emphasis on the use of models as facilitators in stakeholder dialogues (ranging from the super-local level, to the transboundary level. In 1989, I defended my PhD thesis "Ecohydrological Water Flow Analysis of a Swedish Landscape in a 100 Year Perspective", and in 2001 I was appointed as "docent" at Tema the Department of Water and Environmental Studies, Linköping University (Tema V). Recently, I have been responsible for the development of the phosphorus routine of the HBV-NP model. This work is part of the VASTRA programme. At the moment I am involved in the DEMO-project, initiated by local stakeholders, where we are using catchment nutrient models to facilitate the dialogue about how to reduce nutrient loads on the local level. At tema-V I have recently been coordinating the work package "water resources in the river" in a EU-sponsored project about sharing of water resources in the Okavango river basin. I am the secretary of the Swedish IHP (International Hydrological Programme), and engaged UNESCO's HELP-programme (Hydrology for the Environment, Life and Policy).

I am living together with Björn, and our daughter Matilda in a house in Linköping, built in 1917. When we not work or renovating the house, we enjoy life in our cottage at the Baltic coast. I also enjoy food (sometimes dream about opening a restaurant), and travelling.

JOHAN ANDRÉASSON

I came to SMHI in the summer of 2000 to do my master thesis on modelling organic nitrogen leaching from forested catchments. After I had finished my thesis I was employed in the hydrology research group. My first year was divided between several research areas such as developing a new model for grassland fire predictions, using impulse radar snow measurements in an attempt to improve the spring flow volume forecasts and also climate change effects on the water resources in the Lake Vänern region. The latter of these projects was done within the SWECLIM programme and since then I have more and more focused on the impact of climate change on the water resources, although I am still involved also in other research fields.

SARA-SOFIA HELLSTRÖM

I have been working at SMHI, and the research department, since January 2006. So far I have mainly been involved in projects concerning climate change impact on hydrological systems, e.g. in the Pungwe region in Africa, and dam safety issues in Sweden. Since it's a very interesting and exciting field, I enjoy working with such matters. Apart from climate change issues, I am (as the rest of the department) involved in the project of developing a new hydrological model.

My education in hydrology was obtained at Uppsala University where I also took courses in limnology and biology. In the future I hope to be able to benefit by my knowledge in limnology.

In my spare time I like, among other things, to spend time with our dog (a black labrador named Gimli), doing outdoor activities and go horse back riding.

GÖRAN LINDSTRÖM

I started at the SMHI in 1984, after studying hydrology at the Uppsala University. Most of my work at the SMHI has, in one way or another, been related to the HBV model. In the 1980s we worked with the PULSE model, a water quality version of the HBV. I then became interested in the modelling of water pathways and transit times in natural basins, an interest that I still have. Following a rainy fall in 1983 in the upper River Indalsälven, the Swedish Committee for determination of spillway design floods was established in 1985 with the task of developing new guidelines for spillway design flood estimation, and I became involved in the background work of the Committee. The questions of dam safety and the occurrence of floods have been a focus for me ever since. I have also been involved in international projects that the SMHI has carried out in Latin America. In the 1990s I was responsible for the development of the HBV-96 model version, which is pretty much the model version that we still use. In fact, much of the model has been unchanged since Sten Bergström originally made the model in the early 1970s. Over the years, we have experienced that it is difficult to improve a model that was already good to start with. I continue to work with similar questions as before: water quality modelling, climate studies model calibration and uncertainty analysis. Recently I have also begun working part-time with operational hydrological forecasting.

JONAS OLSSON

I have worked at SMHI since late 2001. Much of my work concerns how to improve hydrological (runoff) modelling by using new sources of precipitation input, i.e. data from weather radars and meteorological ensemble forecasts. I am also involved in the development and testing of HBV-NP, a catchment-scale model for phosphorus transport, and MoST, a software for quality assurance in water-related modelling studies. A genereral interest concerns the issue of scale in hydrological processes.

Before coming to SMHI I made a 4-year Postdoc-stay at Institute of Environmental Systems, Kyushu University, Fukuoka, Japan, after having graduated in 1996 at Department of Water Resources Engineering, Lund University. The title of my thesis was "Scaling and fractal properties of rainfall", and the work comprised statistical analysis and modelling of rainfall based on scale-invariant concepts. Later, I have been involved in work applying a similar approach to other processes, e.g. solute transport.

CHARLOTTA PERS

I have worked at SMHI since 2000, and among other tasks a part of my work has been within the Swedish research program VASTRA, which concerns the identification of effective measures against eutrophication of lakes and coastal areas. Within VASTRA we have developed a lake eutrophication model, BIOLA, and a catchment model for nitrogen and phosphorus continues to be developed, HBV-NP. Both models are used in scenario analyses.

During my doctoral studies at Linköping University, Department of Water and Environmental Studies, I worked on organic carbon dynamics modelling in lakes including mechanistic, empirical, stochastic, and Lagrangian modelling, MonteCarlo simulations, and statistical methods for uncertainty and sensitivity analysis.

JÖRGEN ROSBERG

In 1998 I had a time limited employment at the department for Observations at SMHI. This obviously did not deter me since I am now back at SMHI since the spring of 2002, this time at the department of Research and Development. Here I spend most of my time developing and programming the HBV-NP model where the goal is to simulate the transport and retention of nutrients in natural water channel networks. Also GIS processing and database handling for the VASTRA project occupies some of my time.

My studies at the universities of Uppsala (Sweden), Agricultural science (Sweden) and Svalbard (Norway), led me through a wide range of scientific fields mostly connected to geophysics. Although my main subject remained hydrology this included for example geology, oceanography and glaciology.

Days when I am not at work are usually spent outdoors cycling, trekking, skiing, skating etc. or planning and preparing for any such activity.

FREDRIK WETTERHALL

I have worked at SMHI since April 2006, and before that I finished my Ph D thesis entitled Statistical Downscaling of Precipitation from Large-Scale Atmospheric Circulation at the Department of Earth Sciences, Uppsala University. At SMHI my work is focusing on the development of a new hydrological model, uncertainties in hydrological processes and hydrology in climate scenarios. I also have an interest in the problem with different scales in hydrology, and energy balance in boreal forest wintertime.

JULIE WILK

I received my PhD from the Department of Water and Environmental Studies (Tema Vatten) at Linköping University in December 2000 on the topic "Do forests have an impact on water availability? Assessing the effects of heterogeneous land use on streamflow in two monsoonal river basins." I currently share my time between SMHI and Linköping University.

My main research area is catchment hydrology in developing countries which I have approached from a natural science perspective but supplemented with research questions requiring both qualitative and quantitative methods. I have an interest in studying and combining knowledge gained from different sources and methods (e.g. from statistics, hydrological models and local inhabitants) to gain a more holistic view of hydrological issues. When working in a project on the Okavango River Basin (Angola, Namibia and Botswana), I was involved in ascertaining the effects of hydrological related upstream changes on downstream water availability and defining different risk profiles and adaptation strategies to current and future hazards for the local communities in the Okavango Delta.

My current projects on assessing water poverty in a village in India and ascertaining hydrological effects of climate change in chosen South African sub-catchments share the central theme of participatory modelling with the aim of encouraging the participation of local stakeholders throughout the research process in order to increase relevance and applicability of scientific results.

I like travelling and I adore cats.
