Most structural and some nonstructural water projects require significant sunk costs and lead to uncertain economic and ecological outcomes. For instance, building irrigation or flood control dam requires sizable sunk cost, an investment that is difficult to recover later. The dam faces uncertainties in terms of future rainfall, the performance of the dam’s structures and downstream levees, the...

Pollution levels have been increasing in water ecosystems worldwide. A water quality index (WQI) is an available tool to approximate the quality of water and facilitate the work of decision-makers by grouping and analyzing numerous parameters with a single numerical classification system. The objective of this study was to develop a WQI for a dam used for irrigation of about 5000 ha of agricult...

This paper investigates the impact of dams on infant mortality using 32 waves of DHS data that have GPS locations of households. This allows us to estimate the impact of dams on households that reside upstream, downstream, and within its immediate vicinity. We use a sample of over 400,000 children in 17 countries in Africa. In contrast to earlier research on the impact of dams on agricultural p...

When I was elected governor in 1974, the West had a well-established water system. . . . Bureau [of Reclamation] officials and local irrigation districts selected reservoir sites and determined water availability. With members of the western congressional delegation, they obtained project authorization and funding. Governors supported proposals, appearing before congressional committees to requ...

a diverse range of foods has been shown to increase energy and micronutrients intake in the developing countries. it is widely asserted in the literature and development circles that farm household access to irrigation dam can provide a significant improvement of household’s dietary diversity. this study set out to assess the role of kampe irrigation dam on farm household dietary diversity in k...

Rubber dams are inflatable and deflatable hydraulic structures. Thousands of rubber dams have been installed worldwide for various purposes: irrigation, water supply, power generation, tidal barrier, flood control, environmental improvement, and recreation. Furthermore, rubber dams have been used in cold areas where the temperature is as low as –40°C. The simplicity and flexibility of the rubbe...

Four aquatic ecosystems (two rivers and two dams) situated in the western part of Bulgaria were investigated over a three years' period. The River Egulya and Petrohan dam are situated in mountainous regions at about 1000 m altitude, and are not influenced by any anthropogenic sources. Petrohan dam is a site for long-term ecosystem research as a part of Bulgarian long-term ecological research ne...

With a population of more than six billion people, food production from agriculture must be raised to meet increasing demand. While irrigated agriculture provides 40% of the total food production, it represents 80% of the freshwater consumption worldwide. In summer and drought conditions, efficient management of scarce water resources becomes crucial. The majority of irrigation canals are manag...
