We compute rates of sediment removal from the Columbia River, USA plume near field using a control volume technique. By using data from repeated transect passes along the plume axis, we account for variations in plume width, depth, and velocity, and we construct a framework for determining the dominant terms in the complete sediment balance. The contribution due to turbulent sediment flux is es...

Previous work on sample design has been focused on constructing designs for samples taken at point locations. Significantly less work has been done on sample design for data collected along transects. A review of approaches to point and transect sampling design shows that transects can be considered as a sequential set of point samples. Any two sampling designs can be compared through using eac...

Rapid urbanization has made the inner city change quickly with the urban sprawl of the whole city. In China, a mass of urban renewal projects have been carried out for meeting the new need of people’s life. However, the traditional means of total renewal has destroyed the urban heritage seriously, which especially led to the diminishing of historical district space. It is urgent to protect and ...

Purpose Urban consolidation centres (UCCs) are often conceived to improve services in retail stores and potentially reduce costs. However, few studies have examined how retail stores perceive the services a UCC could provide. The purpose of this article is to explore retail stores’ potential demands for different services that a UCC could provide in order to foster the development and implement...

Social workers delivering services in health care settings face unique challenges and opportunities. The purpose of this study was to solicit input from social workers employed in urban hospitals about their perceptions of the roles, contribution, and professional functioning of social work in a rapidly changing health care environment. Using qualitative methods, the university and hospital-bas...

Urban density must be considered a key concept in the description of a city’s urban spatial structure. Countless studies have provided evidence of a close relationship between built density and activity densities, on the one hand, and urban environmental conditions or social practices, on the other hand. However, despite the concept’s common use in urban research, urban density is a rather fuzz...

Urban residents are at risk of health-related illness during extreme heat events but the dangers are not equal in all parts of a city. Previous studies have found a relationship between physical characteristics of neighborhoods and the number of emergency medical response (EMR) calls. We used a human energy budget model to test the effects of landscape modifications that are designed to cool th...
