Since 2009, Swedish municipalities have the possibility of limiting the coastal protection in rural areas with the LIS-tool in order to promote countryside development there. In 2013, Ronneby Kommun pointed out 28 such areas. The goal of this thesis is to describe the development in the coastal areas in Ronneby Kommun between 1960 and 2018, with a special focus on the recent development in the designated LIS areas since 2013. A proposal for the future application of the LIS-tool in the municipal...

Les activités anthropiques ont apporté des changements majeurs à notre système global. Par ailleurs, la matière organique dissoute(MOD) du littoral a une grande influence sur le cycle global du carbone et donc sur le changement climatique. L'apport côtier enMOD représente la matière organique terrestre. Les rivières urbanisées sont fortement impactées par la MOD anthropiqueprovenant des usines de traitement des eaux usées. La MOD chromophorique est un sous-groupe de la MOD qui peut absorber lalu...

Les surcotes de tempête sont souvent sous-estimées dans les modèles hydrodynamiques, ainsi que les grandes vagues dans les modèles de vagues. Les causes possibles sont une sous-estimation des vents dans les modèles atmosphériques et/ou une formulation incorrecte de la tension de vent. Les objectifs de cette thèse sont (1) d’estimer les biais par vents forts dans les modèles atmosphériques (2) de développer une nouvelle paramétrisation du coefficient de traı̂née permettant de réduire ce biais (3)...

Coastal inundation initiated via storm surge by hurricanes and nor'easters along the U.S. East Coast is a substantial threat to residential properties, community infrastructure, and human life. During and after the storm, compounding with heavy precipitation and upland drainage, inundation can be caused by the combination of storm surge and river-induced inland flooding in various locations throughout the coastal plain. Thus, coastal inundation can be expanded from the open coast upstream into t...

The shallow water region is an important portion of the estuarine and coastal waters, since it encompasses the entire land-water margin as the buffer zone and supports one of the most productive ecosystems. When light can penetrate to the sediment, it triggers the benthic microalgae community to perform photosynthesis, resulting in a benthic-pelagic exchange flux different from that of the deeper water. This study utilized the laboratory-measured benthic flux, and a suite of well-calibrated nume...

The occurrence of potential larval habitat, the use of mosquito control, and reported malaria were studied in relation to community and household level ecological variables. Malindi, Kenya was mapped using global positioning systems (GPS), and a geographic information system (GIS) was used to overlay a measured grid, which served as a sampling frame for this research. Grid cells were stratified and randomly selected according to levels of drainage. A stratified cross-sectional survey was conduct...

A sea-level database following a new protocol of quality evaluation standards has been constructed and is used for a comparative analysis to reconcile conflicting hypotheses about Holocene relative sea-level change in the Gulf of Mexico. Sea-level data are assessed quantitatively by assigning errors to both sample elevation and radiocarbon age. Sources of elevation uncertainty include sample thickness, indicative range, sampling errors, and surveying errors. Radiocarbon ages are corrected for bu...

Submarine groundwater discharge (SGD) is a major pathway for nutrient transport in coastal marine systems. There are indications that SGD may also release large amounts of dissolved organic matter (DOM) to the coastal ocean and thus impact coastal ecosystem functioning. DOM is usually quantified as dissolved organic carbon (DOC), which requires discrete sampling. Therefore, detailed time series on tidally-driven SGD cannot easily be obtained for DOC. The chromophoric component of DOM (CDOM) can ...

In this study, four and a half months of ceilometer data from Östergarnsholm are used to analyze cloud related to processes in the boundary layer. Measurements are divided into two categories, which are defined by wind direction: a continental and a marine sector. The results show that there are significant differences in the height of the lowest cloud bases detected for the two sectors, where cloud base heights are lower for the marine wind sector during unstable and neutral conditions. The cei...

Les zones côtières à travers le monde sont soumises à de fortes pressions dues aux changements climatiques globaux, à la destruction d'habitats ou encore à la surexploitation des ressources marines. Ces différentes pressions peuvent induire des changements rapides d'état des écosystèmes caractérisés par de fortes modifications de la biodiversité, avec des écosystèmes entiers cessant de fonctionner dans leur forme courante. En conséquence, la pérennité des biens et des services écosystémiques pro...

L'océan côtier subit la convergence de nombreuses perturbations anthropiques, avec le changement climatique en première ligne. Le réchauffement, l'acidification de l'océan, l'eutrophisation et la désoxygénation se combinent en menaçant les écosystèmes côtiers et les activités humaines associées. Malheureusement, la très forte hétérogénéité spatiale et temporelle de l'océan côtier limite la compréhension des processus biogéochimiques impliqués et leurs réponses face aux perturbations anthropiques...

The production and the usage of plastic material increases since the decade of 1950. Nowadays, the elevated production rate, the misusing and the waste turned plastic material in an urgent environmental and economic problem. One of the major environmental problems related to this issue is the contamination of marine environments by microplastics. These constitute plastic particles of size between 1 and 5 mm. Microplastics might occur by breaking of larger plastic pieces or as a manufactured prod...

Les blocs supratidaux de tempête que l’on trouve au sommet des falaises vont à l’encontre du schéma classique qui décrit l’érosion des falaises. Généralement, le recul des escarpements rocheux se fait au rythme des écroulements gravitaires dont les éléments s’accumulent en pied de falaise, la mer intervenant surtout dans le déblaiement des matériaux accumulés à la base des versants. Dans le cadre de cette thèse, nous étudions les processus d’érosion qui se traduisent par l’accumulation de dépôts...

Anthropogenic climate change has triggered widespread shifts in the global hydrological cycle. In south coastal British Columbia, these changes have led to more winter precipitation falling as rain rather than snow, more rain on snow events, and generally reduced snowpacks. Since snowmelt is a primary source of summer surface runoff and groundwater, snowpack declines have caused severe seasonal streamflow droughts in recent decades. For accurate water supply forecasting under future climate chan...

<p> For decades, traditional remote sensing retrieval methods that rely solely on the spectral intensity of the water-leaving light have provided indicators of aquatic ecosystem health. With the increasing demand for new water quality indicators and improved accuracy of existing ones, the limits of traditional remote sensing approaches are becoming apparent. Use of the additional information intrinsic to the polarization state of light is therefore receiving more attention. One of the major chal...

Climate and longleaf pine (Pinus palustris P. Mill.) radial growth relationships have been documented within its southern and western distribution. However, knowledge of this relationship is lacking along its northern latitudinal range margin (NLRM). Based on the principles of ecological amplitude, limiting factors, and studies of coniferous species in eastern temperate forests of the U.S., we hypothesized that the radial growth of longleaf pine in mixed pine-hardwood forests is responding to w...

Antarctic mass balance is mainly controlled by surface mass balance (SMB, i.e. the net effect of precipitations at the surface of the ice sheet) and ice discharge at its margins, mostly through ice shelves. These floating ice bodies made from ice flowing from the continent to the ocean are buttressed by ice rises (elevation of the sea floor on which ice shelf re-grounds) such as the Derwael Ice Rise (DIR) in Dronning Maud Land (DML). In addition to this role important to consider in the future c...

Eldana saccharina, an indigenous lepidopteran stemborer, is considered the most damaging pest of sugarcane in South Africa. Researchers have advocated the use of an area-wide integrated pest management (AW-IPM) programme as a means of improving the control of this pest. A push-pull strategy was developed as a component of this AW-IPM approach. The push-pull strategy in sugarcane is a habitat management method of pest control that uses plants that are both repellent (Melinis Minutiflora) and attr...

Northwest Coast cultures are commonly designated as "complex hunter-gatherers" (Matson and Coupland 1995:2; Ames and Maschner 1999:13). This means that although food procurement was from foraging, societies had socially hierarchical characteristics generally associated with late-stage sedentary agricultural societies. Tracing the development of social complexity in Northwest Coast prehistory has been a major endeavour in archaeological research but it has often been a progressive theoretical fra...
