Numerical modelling of erosion and sedimentation around offshore pipelines

In this paper a numerical model is presented for the description of the erosion and sedimentation near pipelines on the sea bottom. The model is based on the Navier-Stokes equations and the equation of motion and continuity of sediment.\ud \ud The results of the simulations have been compared with the results of tests in a large-scale facility. The agreement between the results of the simulations and the experimental results is good.\ud \ud The applicability of the method is twofold: firstly, the processes of erosion and sedimentation around bodies on the sea bottom can be simulated; secondly, the method can be used for the design of pipelines, including erosion stimulating elements, such as spoilers

Kennisbasis WOT Fisheries 2011 - what is in the Programme?

The KBWOT Fisheries programme is core to the maintenance and development of the expertise that underpins the statutory obligations of fisheries monitoring and advice for the Netherlands. The structure of the KBWOT Fisheries programme for 2011 changed to reflect the recent discussions on the research direction between IMARES, CVO and EL&I. One of the strengths of the structure of the KBWOT Fisheries programme was the bottom up approach to calls for projects to fulfil the research priorities. This however was seen as giving the programme the potential to miss strategic needs of both the science development within IMARES and the research questions of EL&I, thus the programme now also contains a specific project request on an research subject relevant to IMARES and EL&I needs. The KBWOT Fisheries programme will fund 12 projects in 2011. The projects will investigate competition in exploited fish communities, long term changes in eel populations, the spawning habitat of mackerel, sub-stock structure in fish, trawling impact on benthic communities, quality assurance in fish aging, surveys of shellfish, maturity staging of fish and acoustic methods. Plus a targeted project specifically designed to research needs of IMARES and EL&I will be carried out into the trade-offs in FMSY targets for North Sea flatfish fisheries

The Kennisbasis WOt Fisheries Programme carried out in 2010: Final Report

The KBWOT Fisheries programme is core to the maintenance and development of the expertise that underpins the statutory obligations of fisheries monitoring and advice for the Netherlands. As the WOT obligations of the Netherlands change over time, the KBWOT programme remains flexible and responsive to developments and innovations in methods and policy needs. The core principles of the programme are maintaining expertise whilst being forward looking, ensuring value for money and strong collaboration with client ministries. The programme operates through long term projects (multiannual) and annual projects in response to scientific and societal needs. The KBWOT fisheries programme must operate within the context of the reform of the common fisheries policy (CFP), the development of the EU marine strategy framework directive (MSFD) and the EU Maritime Policy

KB - WOT Fisheries Research; programme for 2010

LNV programme WOT 5 covers the execution of statutory tasks (WOT) in fisheries carried out by DLO. Part of the KB programme, presented in this report, contains resources earmarked to maintain and develop the expertise needed to carry out the WOT programme. As well as maintaining expertise, innovation is an important part of the programme. The programme is also part of the Wageningen UR Kennisbasis and comes under the theme KB01: “Groene en blauwe ruimte”. This report describes the allocation and utilisation of the Kennisbasis budget in 2010. The available budget in 2010 is €621 000. The structure of the KBWOT programme is similar to that in 2009. The money is spent through projects, each of which is described in this report. The projects are split up into four priority research areas: A) Influence of changes in the environment on marine ecosystems, B) impact of fisheries on ecosystems, C) changing fishery management, D) maintenance and international exchange of key WOT expertise. These priority research areas have been developed with the agreement of LNV. All of these areas fall under the wider WUR kennisbasis themes

KB-WOT Fisheries Research; programme for 2008

LNV programme 406 covers the execution of statutory tasks (WOT) in fisheries carried out by DLO. Part of the KB programme, presented in this report, contains resources earmarked to maintain and develop the expertise needed to carry out the WOT programme. As well as maintaining expertise, innovation is an important part of the programme. The programme is also part of the Wageningen UR Kennisbasis and comes under the theme KB01: “Groene en blauwe ruimte”. This report describes the allocation and utilisation of the Kennisbasis budget in 2008. The available budget in 2008 is €621 000. The money is spent through projects, each of which is described here. The projects are split up into 4 research priority areas: A) Influence of changes in the environment on marine ecosystems, B) impact of fisheries on ecosystems, C) changing fishery management, D) maintenance and international exchange of key WOT expertise. All of these areas fall under the wider WUR "kennisbasis" theme

Wettelijke Onderzoek Taken WOT-05 Visserijonderzoek

Dit rapport beschrijft het werkplan voor 2011 van cluster WOT-05 Visserijonderzoek van Wageningen UR. In dit programma worden Wettelijke Onderzoek Taken uitgevoerd die betrekking hebben op het beheer van de visserij op zee, in Nederlandse kust- en binnenwateren en de aquacultuur. Het werkplan is een uitwerking van de nieuwe Uitvoeringsovereenkomst tussen LNV en DLO voor diensten vanwege wettelijke taken op het terrein van visserijonderzoek voor de periode 2011-2015. Bij deze uitvoeringsovereenkomst zijn voor deze periode werkafspraken gemaakt welke de basis vormen voor het werkplan voor 2011
