The Maltese authority Transport Malta requested a mathematical wave disturbance study for the whole Saint Julian\u2019s Bay (including Spinola and Balluta) comparing the present situation with different alternatives of the land reclamation to determine the effects on the wave climate in Saint Julian\u2019s Bay. In an interactive process the design of the land reclamation is optimised to fulfil the criteria of evaluation.\r\n\r\nThe basis for the wave penetration study is the wave climate just outside Saint Julian\u2019s Bay. This \u2018offshore\u2019 wave climate is established with a SWAN<\/a> numerical wave model of the Mediterranean Sea. In this model a 20-year time series of hindcast wind fields (CFRS) is used to determine the \u2018offshore\u2019 wave climate.\r\n\r\nThen the 20-year time series of the wave climate outside Saint Julian\u2019s Bay is transferred into the bay using the numerical wave model HARES<\/a>. For this purpose, a 3D transfer matrix has been set up for many conditions of wave heights, wave periods and wave directions (for various output locations). These HARES calculations include both direction and frequency spreading. The calculations are performed for the present situation and several alternatives of the proposed land reclamation.\r\nWith the 3D-matrices the wave time series outside Saint Julian\u2019s Bay are transferred by interpolation or extrapolation to various output locations inside the bay area. The results are used to establish the local wave climate and to analyse the influence of the proposed land reclamation alternatives on the wave conditions inside the bay.\r\n\r\nTransport Malta required that the wave conditions in the bay shall not worsen due to the construction of the land reclamation. The shoreline of this reclamation will consist of vertical quay walls to accommodate mooring yachts. The main instruments to optimise the layout are the orientation of the quay wall and its reflective properties.\r\n\r\nIn the final design the quay wall is equipped with wave chambers to dissipate wave energy to reduce the reflection coefficient. This results in a more tranquil wave climate in front of the quay wall. The effectiveness of several wave chamber layouts is modelled with the numerical wave model SWASH<\/a>.\r\n\r\nAt Balluta bay the proposed land reclamation has a small positive effect on the beach stability, for the rest of Saint Julian\u2019s Bay the effect of the reclamation on the wave climate is negligible.\r\n\r\n\u00a9 Artist impression San Giljan Aquatic sports club<\/em><\/span>"},"slider":[{"image":1795,"video":""},{"image":1789,"video":""},{"image":1791,"video":""},{"image":1797,"video":""},{"image":1793,"video":""},{"image":1799,"video":""},{"image":1801,"video":""}],"expert_guy":{"left":{"title":"More information?","content":"Please contact Bernard Eikema","linkedin_link":"https:\/\/www.linkedin.com\/in\/bernard-eikema\/","email":"eikema@svasek.nl"},"right":{"title":"Bernard Eikema","designation":"Project leader","photo":874}},"cta":{"title":"MORE INFORMATION ABOUT SVA\u0160EK OR OUR EXPERTISES?","text":"Please contact us or make an appointment.","link":{"title":"CONTACT US","url":"https:\/\/www.svasek.nl\/en\/contact\/","target":""}},"custom_links":{"linked_url":""},"hide":""},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project\/1806","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project"}],"about":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/types\/project"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/media\/1793"}],"wp:attachment":[{"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/media?parent=1806"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/tags?post=1806"},{"taxonomy":"project_category","embeddable":true,"href":"https:\/\/www.svasek.nl\/en\/wp-json\/wp\/v2\/project_category?post=1806"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
