India Ganga River Project
Summary: CPB gave approval for OSE II and requested a proposal for the scope of work as well as cost. Trip to Varanasi was very helpful to determine who to handle solids, as well as where to take samples for baseline information as well as where to dose OSE II. The trip revealed there will need to be a mechanism to mix OSE II with the large volume of water, and to inject aeration as well. O2 ...

Integrated river basin project evaluation: a comparative study
Projects carried out in river basin areas often impose changes in spatial functions that are situated in these areas. For decades, project evaluation was carried out by measuring tangible streams of cost and benefits summarised in a cost-benefit analysis. Recently, environmental and social aspects gradually have got more attention in the public decision making process by means of, for example, ...

4. The Contextual Interaction Theory Chloe Parker
River renaturalization projects are complex implementation processes related to multiple policies. Often they require many years to develop and thus work under a dynamic set of circumstances. In this chapter we will explain Contextual Interaction Theory as our conceptual lens for studying these implementation processes. First we will describe the nature of policy ...

For the water sector, adapting to the effects of climate change is a highly complex issue. Due to its geographical position, The Netherlands is vulnerable to sea level rise, increasing river discharges and increasing salt intrusion. This paper deals with the question of to what extent the historically developed Dutch water safety institutions have the capacity to cope with the ‘new’ challenges of ...

Analysis and projection of runoff variation in three Chinese rivers
Runoff variability is investigated separately for the Wei, the Bei, and the Qing Rivers in China with a focus on their respective differences in monthly flow patterns and flow duration curves (FDCs) between years with and without annual runoff deficit. The number of deficit runoff years increased in the Wei River and changed slightly in the Bei and Qing Rivers, respectively. Monthly flow ...

A case study of regional risk assessment of river restoration projects: Nakdong River Basin, South Korea
An integrated approach to risk assessment that can pose significant challenges to mitigation and adaptation at the local or regional levels in the context of climate change was developed. First, a conceptual framework for flood risk analysis was developed based on the hydrologic hazard and the socioeconomic vulnerability of a region. Second, weighting factors for each indicator were estimated ...

Reconstructing the polder: negotiating property rights and 'blue' functions for land
Dikes were the core of Dutch river flood protection. Near-floods in 1993 and 1995 and debates about climate change, however, led to a rethinking of existing approaches. In the policy directive 'Room for the River' the focus has shifted from infrastructure (dikes) to spatial measures (bypasses, dike relocations, 'green' rivers). While people and land used to be separated from water by dikes, this ...

Why Eastern Himalayan countries should cooperate in transboundary water resource management
Bangladesh, Bhutan, India, and Nepal in the Eastern Himalayas are interconnected by the common river systems of the Ganges, Brahmaputra, and Meghna (GBM). The GBM basin is home to approximately 700 million people, comprising over 10% of the world's population. The economy and environment of the region depend on water, but while the need for water is increasing, poor management and ...

A longitudinal analysis on the perspectives of major world newspapers on the Three Gorges Dam project during 1982–2015
Media communications are least studied in river basin development projects. This paper aims to develop a longitudinal study on how a water resources development megaproject was reported by the world newspapers during its whole life cycle. The development of the Three Gorges Dam project in China (1982–2015) was taken as an example. Newspaper perspectives on eight evaluation themes: time, cost, ...

9. Reflections and Lessons: Contextual Water Management
Being a delta country, the Netherlands has understandable concerns regarding the increasing frequency of high and low water situations as a result of climate change. This has warranted a drastic change of approach to water, land and nature management through a strategy that uses nature‘s resilience to provide for both human and natural environmental needs. The subject of our study ...

A river environment index for Korean national rivers: rationale, methods and application
A methodology for indexing river environmental condition was developed and applied to 269 subsections of national rivers located in the Republic of Korea, based on a river management perspective. The resulting index has been called the River Environment Index (REI). To develop the methodology, a total of 32 factors related to a river's environment were initially investigated, from which ...

The best way to restore environments in the face of climate change
Florida’s Kissimmee River once flowed freely. Fish, birds and other wildlife dwelled in the wetlands it fed. But in the 1960s, spurred by public outrage over flooding, the U.S. Army Corps of Engineers straightened the winding waterway and turned it into a drainage canal. Flip forward a few decades and the river is returning — at least in part. The U.S. Army Corps of Engineers has ...
