博士 / 國立臺灣大學 / 漁業科學研究所 / 99 / In recent years, due to global warming and the rising sea levels associated with it, beach nourishment and groin building have been increasingly employed to protect coastal land from shoreline erosion. These actions may degrade beach habitats, reduce biomass and biotic density, and create new habitats at sites where they are employed. In this study, four approaches were developed to find indicator species from habitats created by coastal structures. These approaches ...

Cette thèse se démarque des études traditionnelles des assemblages céramiques archéologiques conduites au Kenya qui mettent l’accent sur les décorations et les formes. L’approche ici privilégiée est l’approche technologique. Elle a pour objectif d’offrir des informations additionnelles sur une poterie dont la caractérisation ethno-linguistique soulève des débats contradictoires. Cette thèse pose la question de l’origine de la « Tana Ware » (7ème siècle avant JC), où le terme de « ware » décrit u...

Over the last decades, there has been considerable attention in the accurate mathematical modeling and numerical simulations of free surface wave propagation in near-shore environments. A physical correct description of the large scale phenomena, which take place in the shallow water region, must account for strong nonlinear and dispersive effects, along with the interaction with complex topographies. First, a study on the behavior in nonlinear regime of different Boussinesq-type models is propo...

The primary goal of this thesis was to investigate the relationship of canopy photosynthesis (P) to photosynthetically active radiation (PAR) in a 56-year-old coastal Douglas-fir stand (DF49) located on Vancouver Island. Canopy P was calculated as daytime NEP + daytime R[sub e], where NEP and R[sub e] are net ecosystem production of CO[sub 2] and ecosystem respiration, respectively. Half-hourly values of NEP were obtained using an EC (eddy covariance) system consisting of a 3-D sonic anemom...

I studied the dispersion of winter wrens in 100-year-old, second-growth, coastal western hemlock forest at the University of British Columbia Research Forest in southwestern British Columbia from 1978-81. Male winter wrens were territorial on non-overlapping territories at an average density of 60 per km2. An average of 8% were polygamous. Females occupied generally non-overlapping home ranges at least during the breeding period, but were not shown territorial, although this possibility could n...

La recherche a porté sur les contraintes reliées à la modélisation des écoulements des eaux souterraines en aquifère côtier. Dans ces aquifères, la présence concomitante d’eaux douces et d’eaux salées modifient les patrons d’écoulement classiquement représentés par l’équation de Darcy. L’influence de la salinité de l’eau sur ses propriétés (densité) et sur la perméabilité du milieu complexifie la représentation mathématique des équations d’écoulement et la résolution des systèmes d’équations.

L’adaptation côtière est un impératif pour faire face à l’élévation du niveau marin,conséquence directe du réchauffement climatique. Cependant, la mise en place d’actions et de stratégies est souvent entravée par la présence de diverses et importantes incertitudes lors de l’estimation des aléas et risques futurs. Ces incertitudes peuvent être dues à une connaissance limitée (de l’élévation du niveau marin futur par exemple) ou à la variabilité naturelle de certaines variables (les conditions de ...

The Resource Management Act 1991 (RMA) gave councils a mandate and an obligation to promote sustainability. Along with this it also introduced an expectation that the environment will be better managed than previously. Evidence shows that the environment is continuing to be degraded. This is especially evident in the coastal environment where in the early 2000s there has been unprecedented development pressure. The addition of the Local Government Act in 2002 (LGA) has strengthened councils’ sus...

This study focuses on the ecological restoration of a coastal dune ecosystem on the east coast of Vancouver Island that supports bird migration. The area is also a part of the traditional homelands of the Tsawout First Nation. Because environmental degradation has impaired the functioning of both ecological and cultural systems, the restoration of this ecosystem requires a distinctive approach. An “ethnoecological” approach to restoration is presented that seeks collaboration between ecolog...

Climate change and sea level rise will continue to stress the human and natural landscapes over the next century with low-lying deltaic regions characterized by extensive aquifer systems being highly vulnerable to these perturbations. Specifically, groundwater and surface water interactions may be adversely affected by the estimated rise (56-200 cm) in sea level through aquifer salinization. The Bengal Basin is one of the most densely populated of these regions with brackish groundwater already ...

A coastal lagoon is a landform that is influenced by natural processes and human activities. All human activities at the upstream, particularly agriculture and cultivation bring soil, waste, and other materials to the downstream area through the river drains into the lagoon. Even though its position is inland of water bodies, the lagoon is still affected by waves and winds from the sea. Additionally, coastal lagoon will be the depository place for sedimentation from the upland area. Segara Anaka...
