The Role of Decision Support Systems and Models in Integrated River Basin Management

Global Water Partnership | 2013

The world's water issues are increasing in number, coverage and intensity and leading to a lack of water security. The availability of water in acceptable quality and quantity for human needs and for natural systems is paramount for sustaining life. Availability is under a constantly increasing threat from demands created by, amongst other factors, increasing populations, economic sector activities and requirements for environmental sustainability. Allocation issues at local, national and transboundary levels will become more and more contentious and flood and drought risks will be exacerbated by climate change. The IWRM approach has been developed to meet such challenges and to resolve such issues. IWRM assumes a governance system that is based on policy and legislation, institutional roles and a set of management instruments. Model codes and DSSs are among the management instruments which can assist at the management level of water agencies and other water-related institutional units to reach sound, evidence-based...

Basin Water Allocation Planning. Principles, Procedures and Approaches for Basin Allocation Planning

Robert Speed, Li Yuanyuan, Tom Le Quesne, Guy Pegram and Zhou Zhiwei | 2013

This document consists of two parts. Part A introduces the philosophy and key elements of the water allocation process, and describes a framework for the allocation of water at a basin scale. Part B provides a more detailed description of some of the key steps involved in implementing the allocation framework. It includes chapters on approaches o determining the water available for allocation; assessing environmental water requirements, and approaches to implementing these through allocation plans; and the use of economic modelling and assessments to support water allocation planning.

Ecohealth and Watersheds: Watersheds as Settings for Health and Well-being in Canada.

Morrison, K. E., Parkes, M. W., Hallstrom, L. H., Neudoerffer, R. C., Bunch, M. J., & Venema, H. D. | 2012

Human health and well-being are largely determined by upstream environmental and social factors. These factors can be usefully viewed within the physical construct of watersheds (catchments) at various scales. In part, this is due to (i) the hydrological imperative that defines watersheds and determines the movement of water through the landscape and the quantity and quality of water available for human uses, (ii) the importance of water to our economic, social and physical well-being, and (iii) human activity on the landscape that influences the ability of watershed ecosystems to provide the ecosystem goods and services that underlie our health (e.g., attenuation of drinking water contamination, contaminant transport, recreational resources). It follows that health is impacted by governance and management of watersheds. In fact, good watershed governance and management can lead to a double dividend?improved environmental health and improved human health.

Yet many provinces and territories in Canada do not have clear...

Canada's Great Basin: Presumed Abundance and Revealed Neglect in the Mackenzie Watershed

The Walter and Duncan Gordon Foundation | 2011

If water is spilled on a map of Canada, the water flows down, flows south. Yet most of Canada's freshwater runs north into the Arctic Ocean, and most of this is via one grand river - the Mackenzie. The Mackenzie River Basin is a global treasure, and provides enormous life-sustaining, cultural and spiritual value for both the Aboriginal and non-Aboriginal communities that live there. Yet the Mackenzie now faces many threats to its natural state, including the effects of the Alberta oil sands on downstream water quality and quantity and a mega-dam proposed in British Columbia known as "Site C."

Learn about the importance of the Mackenzie River Basin, and what governments, foundations and NGOs, and individual Canadians can do to ensure its survivial by reading Canada's Great Basin.

Integrated Water Resources Management

Global Water Partnership (GWP) | 2000

The paper is divided into two main parts. The first part puts forward a strong case for applying IWRM globally and defines the IWRM concept and process. The second part provides additional advice and guidance on how IWRM could be implemented in different conditions.
