Abstract:

This thesis imagines an ecological future for the post-industrial landscape of Govan Graving Docks, situated on the banks of the River Clyde in inner city Glasgow. The research is framed by a context of urban renewal and at times violent change in early 21st century Glasgow which has seen the city’s riverside transformed, with centres for culture, tourism and entertainment built on its infilled docks and sites of dereliction. Prompted by the development priorities of this change, and the nostalgia for an industrial past that has become a ‘way of seeing’ the river, this research seeks to better

Thesis (MEng)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: Sedimentation and the effects it has on turbine blades was the primary problem identified in run-of-river (RoR) hydropower schemes. Sedimentation in RoR hydropower schemes also increases trash rack blockage and reduces energy output in the long-term. Damage occurs to all underwater parts that come into contact with sediment. The main concern is sediment passing through the hydropower intake and causing turbine damage. The reason for the abrasion and cavitation of turbine blades is increased sediment loads in river channels. T

Abstractions from rivers are however not without problems. Firstly, river ow is variable and to deliver a constant yield is difficult. Secondly, rivers transport sediment which will be included in the diverted ow. Sediment control at diversion works have been studied for many years and this study attempts to gain further knowledge on certain sediment control features of diversion works.

Abstract:

Water management that alters riverine ecosystem processes has strongly influenced deltas and the people who depend on them, but a full accounting of the trade-offs is still emerging. Using palaeoecological data, we document a surprising biogeochemical consequence of water management in the Colorado River basin. Complete allocation and consumptive use of the river's flow has altered the downstream estuarine ecosystem, including the abundance and composition of the mollusc community, an important component in estuarine carbon cycling. In particular, population declines in the endemic Colorado de

The extreme flooding event that occurred in 2013 in Alberta, Canada was at time the most costly natural hazard event in the nation’s history with damages exceeding $5 billion.

In order to validate the design of the flow diversion structures, a large (1:16) scale physical model was constructed.

In this work bubble curtains are evaluated through an experimental parametric study, mainly regarding two quantities, defined here as the overall bubble coverage of the background, as well as the occurrence of large tears in the curt
