A hybrid partial and general equilibrium modeling approach to assess the hydro-economic impacts of large dams: The case of the Grand Ethiopian Renaissance Dam in the Eastern Nile River basin

A novel integrated hydro-economic modeling framework that links a bottom-up partial equilibrium (engineering) model with a top-down (economic) general equilibrium model is developed for assessing the regional economic impacts of water resources management and infrastructure development decisions in a transboundary river basin. The engineering...

The Transboundary Impacts of Trade Liberalization and Climate Change on the Nile Basin Economies and Water Resource Availability

A multi-country, multi-sector computable general equilibrium (CGE) model is used for the first time to evaluate the economic and water resource availability effects of trade liberalization (removal of import tariffs) and facilitation (reducing non-tariff barriers) under climate change in the Nile Basin. The analysis uses the GTAP 9 Database...

The economy-wide impacts of climate change and irrigation development in the Nile Basin: A computable general equilibrium approach

A multi-country, multi-sector computable general equilibrium (CGE) model is employed to evaluate the economy-wide impacts of climate change under the IPCC's A2 and B1 scenarios and existing irrigation development plans in the Nile basin. The study reveals that climate change adversely affects mainly downstream Egypt and to a lesser extent...

Day-to-day origin-destination tuple estimation and prediction with hierarchical bayesian networks using multiple data sources

Prediction of traffic demand is essential, either for an understanding of the future traffic state or so necessary measures can be taken to alleviate congestion. Usually, an origin-destination (O-D) matrix is used to represent traffic demand between two zones in transportation planning. Vehicles are assumed to be homogeneous; the trips of each...

An experimental study of transitional pulsatile pipe flow

The transitional regime of a sinusoidal pulsatile flow in a straight, rigid pipe is investigated using particle image velocimetry. The main aim is to investigate how the critical Reynolds number is affected by different pulsatile conditions, expressed as the Womersley number and the oscillatory Reynolds number. The transition occurs in the...

Localized turbulence in pipe flow

In this thesis the transition to turbulence in pipe flow is investigated. At low Reynolds numbers, the flow returns to the laminar state spontaneously. At high Reynolds number a small perturbation causes the flow to suddenly become turbulent. In the intermediate regime localized turbulence is observed. This regime is investigated using...

Quantitative measurement of the lifetime of localized turbulence in pipe flow

Transition to turbulence in a pipe is characterized by the increase of the characteristic lifetimes of localized turbulent spots (‘puffs’) with increasing Reynolds number (Re). Previous experiments are based on visualization or indirect measurements of the lifetime probability. Here we report quantitative direct measurements of the lifetimes...

Repeller or Attractor? Selecting the Dynamical Model for the Onset of Turbulence in Pipe Flow

The collapse of turbulence, observable in shear flows at low Reynolds numbers, raises the question if turbulence is generically of a transient nature or becomes sustained at some critical point. Recent data have led to conflicting views with the majority of studies supporting the model of turbulence turning into an attracting state. Here we...

Kustverdediging na 1990 (Kustnota 1990): Technisch rapport 18: Berekeningsresultaten beleidsalternatieven

Vanuit een beschrijving van beleidsanalyse in algemene zin en de gebruikelijke terminologie en definiering ervan, wordt toegewerkt naar een specificatie van de voor de discussienota 'Kustverdediging na 1990' gehanteerde beleidsanalytische aanpak. Hierin wordt de doelstelling van de studie uitgewerkt, wordt de uitgangssituatie gespecificeerd en...

Kustverdediging na 1990 (Kustnota 1990): Technisch rapport 17: Systeemanalytisch model

Het doel van de discussienota 'Kustverdediging na 1990' is het voorbereiden van beleidskeuzen met betrekking tot de landelijke aanpak van de kustverdediging. Een groot aantal afwegingen en keuzen speelt hierbij een rol. Het is noodzakelijk het gehele scala aan mogelijkheden te vertalen in een aantal goed gedefinieerde beleidsalternatieven. Deze...
