As scouring around foundations is the most common cause of bridge failures, one of the most pressing questions of this research is to determine whether or not it is possible to predict the critical shear stress of different soil types using only soil property information. This report shows that it is possible to predict critical shear stress and determines the soil properties that are required to predict the critical shear stress based on soils from Georgia. Multiple methods to predict soil erodibility categories are developed based on the amount of soil information available to the researcher. The report shows how the methods to predict soil erodibility can be integrated with HYRISK, a scour risk assessment tool. In particular, the probabilities of bridge failures and expected economic losses are calculated for approximately 40 bridges in Georgia; soil erodibility characteristics for these bridges are calculated using the methods developed in this thesis. The goal of this thesis is to provide a faster and more cost-effective approach to calculate critical shear stress ranges likely to be encountered at a bridge foundation. Implementation of theses methodologies will help balance funding for new and existing bridges while simultaneously ensuring safe bridge foundation and minimizing economic consequences associated with overbuilding a bridge and/or having to retrofit or replace a bridge that has scour damage due to underbuilding it to withstand a major storm event.

The Coast Salish subsistence economy has been characterized by local fishing adaptations to regional ecological variability (Mitchell 1971a.) This dissertation explores the temporal depth of these adaptations in the traditional territory of the Coast Salish, the Gulf of Georgia. Many researchers have used this, Donald Mitchell’s (1971a), model to develop theories of regional cultural development. Many of these interpretations present social complexity or social inequality – a hallmark of Northwest Coast social complexity – as having developed more or less in lock-step with the specialized fishing adaptation described among the Central Coast Salish, around the Fraser River. The temporal depth of this adaptation and the “Diversified” fishing adaptations described among the Northern and Southern Coast Salish, as well as their developmental relationship, are not well understood. In exploring this problem, this study evaluates whether or not the ecological ethnographic model is representative of the archaeology of these cultural subareas. A gap in the regional dataset which corresponds with a large portion of Mitchell’s (1971a) “Northern Diversified” fishing subarea has largely presented a previous study of this type. Recently excavated sites in traditional shíshálh territory provide artifact and archaeofaunal data that fill in this gap. These data are analyzed along with existing data from the Northern subarea and from the Central Gulf of Georgia (River and Straits Fishing subareas). The results of this study significantly broaden our understanding of prehistoric Coast Salish socioeconomic diversity, and test the assumed salmon specialization on the Fraser River and its primacy the development of regional ethnographic characteristics, especially pronounced social inequality. The results also shed light on the prehistoric importance of herring, a decreasingly overlooked resource in Northwest Coast archaeological studies, and advocate for the use of fine mesh recovery for quantifying the relative importance of fish species.
