Bio-Physical Closure Criteria Without Reference Sites: Realistic Targets In Modified Rivers, Melanie L. Blanchette, Mark Lund, Robyn Stoney, Digby Short, Colm Harkin
Research outputs 2014 to 2021
The use of reference sites for establishing closure criteria in areas disturbed by mining activities is common practice. ‘Reference’ sites are those considered to be largely unimpacted by anthropogenic activity (retaining desirable natural characteristics), and occurring near disturbed sites. Sites are considered rehabilitated when their biophysical condition approximates that of the reference site. However, this approach often creates impossible or unrealistic targets for miners seeking to close rehabilitated lands. For example, reference sites are often limited in availability (or non-existent) due to impacts by other land uses. Further, any available reference sites might not be realistic matches for the rehabilitated …
Analysis Of Right-Turn Lane Length In Left-Hand Traffic Countries At Signalised Intersections Of Urban Roads, Noura Thomas
Analysis Of Right-Turn Lane Length In Left-Hand Traffic Countries At Signalised Intersections Of Urban Roads, Noura Thomas
Theses: Doctorates and Masters
Analysis of the right turn lane length of urban roads in left-hand traffic countries, such as Australia, UK and India (left-turn lane length in right-hand traffic countries such as USA), at signalised intersections encounters two main geometric features namely, deceleration length and storage length. The literature shows that in routine practice, the deceleration length is generally estimated by using constant deceleration rate. Many researchers consider this assumption for all design speeds unrealistic as it does not reflect the influence of the pavement condition. Hence, it may be desirable to consider the pavement’s condition in terms of its longitudinal coefficient of …
