1. Relationships between Atmospheric Circulation and Wind Erosion in Southern Sweden and Australia
Sammanfattning : Wind erosion is a serious threat to soil resources as it causes depletion of the fine fractions that may result in a less fertile soil. Wind erosion encompasses several processes of which many are related to climate variables. To date, there is little work performed on how wind erosion relates to climate and climate change. LÄS MER
2. Swash Processes and Dune Erosion: Emphasis on Vessel-Generated Waves
Sammanfattning : In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastline changes as a result of exposure to vessel-generated waves has become a topic of increased research.

3. Resistance of Clay Brick Masonry Façades to Wind-Driven Rain : Repointing of Eroded Mortar Joints
Sammanfattning : Clay brick masonry façades are commonly used due to their high-performance durability. However, exposure to climate agents such as wind-driven rain (WDR), freeze-thaw cycles, and wind abrasion cause deterioration of masonry façades over time. LÄS MER
4. Dust from mining area and proposal of dust emission factors
Sammanfattning : Mining generates great deal of particulate matter, especially for surface mining. The principle of dust generation is based on the theory of soil wind erosion. This thesis theoretically and experimentally dealt with mining dust. In chapter 1 the development of study on soil erosion by wind and mining dust were introduced. LÄS MER
5. Estimation of industrial dust using exposure-profiling method
Sammanfattning : Dust is a primary cause for air quality deterioration, as well as a potential health hazard. Mining and construction sites, in particular, are the most profound in dust generation. The possible source activities are drilling, loading, transporting, dumping, crushing, stockpiles, waste rock and unprotected open surfaces, etc. LÄS MER
