Objectif Description:WL | Delft Hydraulics' experimental facilities are among the largest and best equipped in the world. They permit projects ranging from fundamental research on hydrodynamics and morphology in rivers, estuaries, coastal zones and seas to applied research on breakwaters, components of offshore platforms, pipelines and dredging equipment. Access is provided to the following unique experimental facilities: The almost 100 m long Sand flume, which is well suited for the study of river hydromorphological aspects. This facility is unique for its sediment handling system which enables a continuous flow of water with a specified amount of suspended sediment with a specific grain size distribution. The 130 m long Tidal flume, which can be considered as a schematised estuary. Tide, fresh water discharge, salinity, silt and oxygen concentration can be controlled at its boundaries, which is unique in Europe. Both a tidal flow and wind waves can be generated. The Rotating annular flume and complementary facilities are well suited to carry out detailed studies on the various processes which cohesive sediments undergo in fresh and salty waters, including the direct measurement of bottom shear stress. This facility is unique for its hydraulic loads, its instrumentation and the possibility to carry out tests with bio-chemical or polluted sediments in a temperature controlled environment.The Oscillating water tunnel, which can be used to investigate the influence of oscillatory flow on the behaviour of bed material on scale 1:1. Tests can be performed with either random or periodic wave conditions, as well as combined flow and wave action, which is unique for its scale and accuracy of hydraulic conditions. The wave paddle of the 230 m long, 5 m wide and 7 m deep Delta Flume (Wave flume for large-scale testing) can generate regular or irregular waves up to a height of 2.5 m. The flume can be used for large-scale experiments reproducing hydrodynamic loading, interaction with small and large bodies and sediment transport. This facility is unique because of its size in combination with a second-order wave steering system and active re-reflection compensation, for both short waves and long waves. The 32 m wide and 45 m long Multi-directional wave basin is equipped with a 26 m wide wave paddle allowing the generation of swell and short-crested waves propagating at any direction within -/- 45 and at the same time reproducing directional spreading. It has an unique reflection compensation system which also suppresses oblique waves at the wave boards. The 55 m long, 1 m wide and 1.2 m deep Glass-wall wave flume has a unique software controlled wave damping system enabling the suppression of parasitic waves. It is also equipped to study wave-current interaction. The Test rig for non-return valves allows the dynamic testing of check values ranging from 300 mm to 800 mm and for the calibration of flow meters up to a diameter of 2000 mm.The non-stationary, dynamic, testing of two phase flow is unique in Europe. The Dredging flume, with a variable length up to 50 m and width of 9 m can be used for virtually any dredging research project under realistic boundary conditions for various types of soil and rock, which is unique in Europe. By the large scale of the experimental facilities, which avoids scale effects often limiting the applicability in other facilities, the projects significantly contribute to the development of our knowledge of our wet environment and the prediction of changes in our environment, caused by man or nature. State-of-the-art measuring instruments, data-acquisition and processing systems and modern support facilities, such as library, computers and processing & printing is also provided. In addition, the visiting researchers are offered a scientific intellectual environment, with assistance and guidance from WL | Delft Hydraulics' experts covering the wide spectrum of hydraulics and related topics.Application:Researchers groups are invited to submit proposals to gain access to any of the above mentioned facilities. The proposal must give a detailed description of the research project, including work programme; names, nationalities and places work of the user group; reason of why the facility is chosen; an estimation of required access days (including days necessary to construct the test set-up(s) in the facility) and when. The scheme is intended to provide access for short periods, normally not exceeding 3 months. Proposals should not be longer than four pages and have to be send to WL | Delft Hydraulics.Project Manager:Mark Klein Breteler, WL/Delft Hydraulics, Rotterdamseweg 185, Delft 2600MH, P.O.
