A new setup to study the influence of plant growth on the consolidation of dredged cohesive sediment

Dredged cohesive sediment is progressively being used for wetland construction. However, little is known about the effect of plant growth during the self-weight consolidation of this sediment. In order to check the feasibility of such a study, a new experimental setup has been constructed. As an example, the effect of Phragmites australis on the...

Convex modeling of pumps in order to optimize their energy use

This study presents convex modeling of drainage pumps so that real-time control systems can be implemented to minimize their energy use. A convex model is built based on pump curves and then used in mixed-integer optimization to allow pumps to be turned on or off. It is implemented as an extension to the open source software package RTC-Tools...

The Political Morphology of Drainage—How Gully Formation Links to State Formation in the Choke Mountains of Ethiopia

To understand why soil erosion is persistent despite three decades of massive investments in soil conservation, this paper explores how drainage and soil conservation change a hill slope in the Choke Mountains. By paying close attention to the practices that reshape the hill, we account for the active roles of people and material flows in...

Water Management on the Island of IJsselmonde 1000 to 1953: Polycentric Governance, Adaptation, and Petrification

One of the central tenets of adaptive management is polycentric governance. Yet, despite the popularity of the concept, few detailed case studies of polycentric governance systems exist. In this paper, we aim to partly fill this gap. We describe water management between the years 1000 and 1953 on the Dutch island of IJsselmonde in the...

Water Law and Organization (Dutch version)

Lecture notes in DUTCH for course CIE5500, providing a detailed overview of Dutch and European water law concerning surface and groundwater, the North Sea and the Wadden Sea, water services, flood protection, spatial planning, nature protection, water management organizations (e.g. the water boards), financing and legal protection....

Integrating GIS, remote sensing and mathematical modelling for surface water quality management in irrigated watersheds

The intensive uses of limited water resources, the growing population rates and the various increasing human activities put high and continuous stresses on these resources. Major problems affecting the water quality of rivers, streams and lakes may arise from inadequately treated sewage, poor land use practices, inadequate controls on the...

3D Geological Object Recognition in High-Resolution Seismic Data: A Case Study from a Palaeocene Fluvio-Estuarine Reservoir in Suriname

The objective of this study is to develop methods for extracting and quantifying sedimentary bodies in 3D high-resolution seismic data. A case study was used with an exceptionally high-resolution seismic and a large number of wells: the Palaeocene Tambaredjo field in Suriname. A large-scale interactive 3D visualization system was used to permit...

Model predictive control on open water systems

Human life depends on water daily, especially for drinking and food production. Also, human life needs to be protected against excess of water caused by heavy precipitation and floods. People have formed water management organizations to guarantee these necessities of life for communities. These organizations manage a water system within the...

Spankrachtstudie, deelrapport 6: Nadere analyses en verdiepingsslagen in het Benedenrivierengebied

Ontwerpopties Spuimiddel Afsluitdijk

In het licht van het WIN-project en op grond van de notitie "Aanpak Wateroverlast" gaat het in dit project erom de spuimiddelen in de Afsluitdijk uiterlijk in 2007 zodanig vorm te geven dat deze in ieder geval tot halverwege de volgende eeuw (2050) voldoen aan de eisen die daar naar het huidige inzicht aan gesteld moeten worden. Belangrijkste...

Toepassing van de kansberekening op den regenval met het oog op polderbemaling

This study aims at aiming an insight into the rainfall in the Netherlands with regard to the determination of the desirable capacity of draining-mills. With this end in view a statistical investigation has been made of the data of the daily quantities of rain during the years 1890 up to 1939 inclusive, at Boskoop, Leeghwater and Hoorn. First of...
