11. Transport of Arsenic and Heavy Metals to Lake Poopó - Bolivia Natural Leakage and Anthropogenic Effects
Sammanfattning : Bolivia, a country located in the center of South America, has in the west part an Andean region, where the Poopó Lake is located. The area has many mineral resources, and thus since thousands of years,mining activity has had a large importance; however, mainly since colonial times, the extraction of these resources has been indiscriminate and the region of the Poopó Lake, has suffered the consequences of environmental contamination.

12. Rainfall-Runoff Modelling Using Artificial Neural Networks (ANNs)
Sammanfattning : Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. LÄS MER
13. Environmental impact of peat mining : Development of storm water treatment methods
Sammanfattning : Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. LÄS MER
14. Conceptual Runoff Models for Material Transport Estimations
Sammanfattning : Catchment-scale material transport models are today important tools for water and environmental management. However, modelling of material transport is extremely complex due to the physical, chemical and biological processes involved. LÄS MER
15. Conceptualization of solute transport using time domain reflectometry. A combined laboratory and field study
Sammanfattning : Solute transport in the unsaturated zone is a complex process. The first of the two objectives for this study was to examine how it could be conceptualized under different flow conditions. LÄS MER
