Phytoplankton are sensitive to changes in river ecosystems. However, the spatial impacts of dams on phytoplankton communities have not been well documented, and the relationships between environmental drivers and phytoplankton communities in different types of river reaches need to be further...

The study was done on the White Volta River that flows from Burkina Faso through Ghana into the Atlantic Ocean to analyze the frequency of flooding so as to provide a basis for flood prediction to protect life and property. Analysis of floods is important in management of peak discharges in...

Place-based investments can have unintended general equilibrium effects and face challenges of time inconsistency. This paper simulates the granular impact of alternative spatial and temporal designs of such investments, using Quantitative Spatial Models where the strategy of the policymaker is...

We investigate how reforestation contributed to stabilization of riverine water levels in South Korea. For the purpose, we estimate an equation capturing dynamic relationships among rainfall, upstream-area tree stock, and downstream water levels in three river systems of Hongcheon, Mangyeong,...

The construction of large dams is one of the most costly and controversial forms of public infrastructure investment in developing countries, but little is known about their impact. This paper studies the productivity and distributional effects of large dams in India. To account for endogenous...

The Klamath River, draining some 12,000 square miles in southern Oregon and northern California, was once the third largest salmon stream on the West Coast, the life force of Native Americans. The river runs 263 miles from headwaters in Oregon and flows through the Cascades to the Pacific Ocean...

Floods are amongst the greatest natural hazards in the world. In the last decade, many flood events have been observed and recorded in Greece, which have had a direct effect on river ecosystem consistency. Flood hazard assessment is a critical parameter for flood hazard areas identification and...

During the lockdown imposed due to the first wave of the coronavirus disease (COVID-19) pandemic, there were several media reports of citizens flouting the lockdown rules in the United States. Upon closer investigation it was found that the rules were flouted mostly so that people could spend...

This learning note is the second of a 4-note-series developed by the Water Global Practice (GP) Climate Change Team to highlight successful examples of water operations that support climate change-related activities andprovide useful lessons and recommendations for project design

[enter Abstract BodGovernment plays an important role as a well-being capital provider through policies, strategies, or even direct provision to local residents to improve their livelihoods. Pak Mun Dam is one of the most controversial dams in Thailand, and government intervention is needed to...

Small dams play an important role in the provision of many kinds of benefits, such as drinking and irrigation water supply, flood control, small/mini hydropower generation, fishing, and so on. They are particularly important in rural and agricultural areas. Agriculture remains an engine of rural...

Fonte de la banquise, disparition des glaciers, recul de l'enneigement, montée des eaux, salinisation des nappes, assèchements des sols, le réchauffement climatique bouleverse le vivant et le non-vivant. Même le bon vieux cycle de l'eau qui paraissait totalement indolore lorsqu'on le...

"Electricity was key to Hong Kong's success. Hong Kong had one of the world's highest economic growth rates from the 1940s through the 1980s, due in large part to an ample supply of electricity at a time when most of Asia struggled to power factories, let alone light homes, giving it a ten-year...

To ensure the water availability from small dams in the Pothwar Plateau of Punjab, two dams namely Khasala and Jawa were investigated. Pothwar Plateau has erratic rainfall pattern and depends on rainfall for agriculture production. The construction of small dams in this region provides a...

The flooding problem in San Jorge Samar may be solved through an effective implementation of flood control program. As such, the primary purpose of this study is to estimate the potential parameters of flood occurrence of the Gandara River along San Jorge channel through its topography,...

Since 1980 river floods in Europe have resulted in over 4,700 fatalities and caused direct economic losses of more than €150 billion (2013 values), and future risk is likely to increase due to the combination of climatic and socio-economic drivers. As such, reliable research works are needed...

Objective – Dams in Selangor before, is located far from the urban area without any interference from human activity. But over the time, the dam now approached by municipal area with the threat. The objective of this study is to look at the influence of human activities at the seven major dams...

More than a hundred hydropower dams have already been built in the Amazon basin and numerous proposals for further dam constructions are under consideration. The accumulated negative environmental effects of existing dams and proposed dams, if constructed, will trigger massive hydrophysical and...

Global sea level rise (SLR) variations have undeniably begun to make an impact on highly vulnerable economies. These impacts of SLR are a key component of the projected economic damage of climate change, an important input to climate change policies and adaptive measures. This paper considers...

Chinese engagement in Southeast Asian dam projects is usually conceptualized by scholars as engagement directly driven by China's political leadership as part of a larger package whose terms would only be favourable to the Chinese party. This paper argues against this notion, conceptualizing...

This study estimates and compares the effects of small and large irrigation dams on cropland productivity in South Africa. To this end, a panel data set of South African river basins is constructed. The econometric analysis reveals that although large dams increase cropland productivity...

This paper uses a dynamic macro-micro framework to evaluate the potential distributional effects of the expansion of the Panama Canal. The results show that large macroeconomic effects are only likely during the operations phase (2014 and onward), and income gains are likely to be concentrated...

Effective sharing mechanisms of joint costs among beneficiaries of a project are a fundamental requirement for the sustainability of the project. Projects that are heterogeneous both in terms of the landscape of the area under development or the participants (users) lead to a more complicated...

Dams are essential for water storage and hydropower generation, but change river flow patterns and endanger local environments. Dam projects may further exacerbate already existing problems in trans-boundary rivers. We consider three scenarios of institutional factors: (1) each country pursues...

A review of models for river basin development, operations, management, water quantity and quality, recreational demand, countrywide planning, and multiple objective planning.Piecemeal approaches to river basin development and management may not fully recognize the interactions and...

While decentralization holds out the promise of increased flexibility and efficiency, the preconditions for realizing it are daunting. To draw lessons for productive decentralization in integrated river basin management, this paper surveys the decentralization experience in education, health...
