Predicting the ecological consequences of river management for a riverine cyprinid fish.
Current river management seeks to resolve a compromise between stakeholder interests, ecosystem services provision and conservation aims, especially in relation to assessment of ecosystem health. While management decisions should be evidenced-based, current population and habitat models fail to …

Analysis of land-cover change in the Kogmans River (H3) secondary catchment : impact of land degradation and river management on flood severity
… to understand what role the landscape, and the management thereof, played in the March 2003 floods in the Kogmans River catchment. The Kogmans River (H3) secondary catchment is situated in the Klein (Uttle) Karoo region of the Western Cape, approximately 170km east of the city of Cape Town.

Enabling sustainable river futures: Exploring institutional interventions
Increasing concern over deteriorating health of river systems has prompted a shift in river management practices from a technocratic ‘command-and-control’ focus towards notions of river repair. Key elements and principles of this emerging approach are encapsulated in ‘sustainable river management’, …

The Kuils River multiple: versions of an urban river on the edge of Cape Town, South Africa
… diverse ways of knowing and being with the Kuils River, located in Cape Town, South Africa, are shaped and in turn shape the river. The management of water (in pipes and rivers) and the development of water infrastructure are deeply rooted in societal development agendas that, over time, have been …

A framework for river restoration planning : considering conceptual and structural perspectives from case studies of the Liao River in China and the Kalgan River in Australia
… with many of the environmental problems of river systems. It is also recognized that management decisions have a greater chance of being successful if they are based on a thorough understanding of a concept or a plan. A review of current studies on river restoration and river restoration …

A Riverine Ecosystem Service Cascade Model (RESCaM) framework for assessing ecosystem service provision as applied to English geomorphic river types
Riverine ecosystems are considered the lifeblood of the Earth and because of this, have been exploited for centuries for social, agricultural and industrial development, resulting in their environmental degradation and simplification. This has led to a shift in the natural processes and functions …

The Ebb and flow of policy, economics, and science: an analysis of policy drivers in the Missouri River Basin
The Missouri River basin underwent a major transformation when the United States Congress approved the Flood Control Act of 1944 and the Bank Stabilization and Navigation Project of 1945. Generations removed from those national policy decisions, the long-term effects are now quantifiable. The …

Power and Science in Participatory Watershed Planning: A Case Study From Rural Mexico
… characterizes citizen participation in watershed management and examines the validity of explicit and implicit assumptions that participatory watershed planning models are based upon. Contrary to the claims of participatory watershed planning, consensus-based decision-making did not result in …

The Life Cycle of Dams: An Analysis of Policy Change on the Rogue River, Oregon
Every river system contains a unique set of attributes including biophysical characteristics, human created infrastructure, and stakeholder user groups. This thesis utilizes Lowry’s (2003) “Theoretical Framework for Policy Changes” to provide an analysis of fundamental policy change that occurred …

Numerical Modelling of Braiding Processes in Gravel-Bed Rivers
Gravel-bed braided rivers are distinctive natural environments that provid a wide range of key environmental, economic and recreational services. There is, however,a growing concern that over the twentieth century, an increasing number of braided rivers have metamorphosed into wandering or single …
