C. den Heijer, Coastal Engineering (TU Delft) In collaboration with Deltares U.S. Geological Survey Short summary Hurricane Sandy (2012), which made landfall in New Jersey on October 29th, made devastating impact on the East Coast of the USA and struck major parts of New York City, including the economic centre of Manhattan. The total damage (in the USA and Caribbean) is in excess of 100 billion US$ with estimates ranging between 78 and 97 billion US$ for direct damage and over 10 to 16 billion US$ for indirect damage due to business interruption (M. Kunz et al., 2013). Modelling impact (e.g. damage, fatalities) in the coastal zone due to hazardous storm events is a hardly explored practice. It is difficult to predict damage correctly where damage observations are scarce and the physical processes causing the damage are complex, diverse and can differ from site to site and event to event.

  • Het Eindadvies Van De Adviescommissie Toekomst Afsluitdijk
    Adviescommissie Toekomst Afsluitdijk Eindadvies juni 2011 Adviescommissie Toekomst Afsluitdijk Eindadvies juni 2011 Den Haag, 1 juni 2011 Aan: De Staatssecretaris van Infrastructuur en Milieu Betreft: Eindadvies Adviescommissie Toekomst Afsluitdijk Geachte heer Atsma, Hierbij bied ik u het eindadvies aan van de Adviescommissie Toekomst Afsluitdijk. De commissie beoordeelt in dit advies zes toekomstvisies op de Afsluitdijk. Daarbij gaat de primaire aandacht uit naar waterveiligheid, maar de commissie spreekt zich ook uit over voorstellen voor duurzame energie, natuurontwikkeling, mobiliteit, recreatie en zilte teelt. In november 2010 vroeg de commissie reeds uw aandacht voor de zorgelijke staat van het veiligheidsniveau van de Afsluitdijk en de sluizen. Met name het veiligheidsniveau van de schuitsluizen ligt ver onder de wettelijke norm. Spoedig herstel van het veiligheidsniveau is daarom vereist. Ik maak graag van de gelegenheid gebruik om het directoraat-generaal Water en Rijkswaterstaat te complimenteren met de openheid van het proces dat de afgelopen jaren voor dit project is doorlopen. Door de markt ruimte te bieden voor innovaties en ideeën voor extra maatschappelijke functies kan op termijn meer mogelijk worden gemaakt op en rond de Afsluitdijk. De ervaring met dit proces biedt een uitnodigend perspectief voor toekomstige projecten. Ook voor de vervolgfase van dit project kan nauwe samenwerking met de markt meerwaarde bieden. De commissie adviseert om de mogelijkheden te onderzoeken van een integrale aanbesteding van het ontwerp, de aanleg de financiering en het onderhoud van dijklichaam, sluizen en waar mogelijk de kansrijke voorstellen. De commissie sluit daarmee aan bij de ambities van het kabinet op het gebied van publiek-private samenwerking, zoals verwoord in het regeerakkoord.

  • Kopeopeo Canal Remediation Project Flood Management Plan Condition 7.1 Resource Consent 67173
    Kopeopeo Canal Remediation Project Flood Management Plan Condition 7.1 Resource Consent 67173 BOPRC ID: A2708898 MEMORANDUM To: Brendon Love Project Manager - Kopeopeo Canal Remediation From: Peter West B.E. (Hons), CPEng, MIPENZ Date: 28 September 2017 Contract Engineer File Ref: Objective Id: Subject: Kopeopeo East Canal Remediation Project; Flood Management Plan 1 Executive Summary Bay of Plenty Regional Council has received resource consent to remove and treat contaminated sediment from within the Kopeopeo East Canal (the Canal) by a wet-dredging method. This report primarily addresses the detailed conceptual flood-management and drainage aspects of the project specific to the proposed dredging method. It is intended that this report should provide a complete treatment of the relevant material, but in places to improve readability, reference has been made to our previous and/or supporting memoranda (references at the end). This report is in two parts: Part 1 discusses relevant aspects of flood management that form necessary background material, or that have not been previously addressed – either from changes in the proposed method; or from developments in supporting information as the project has unfolded. Part 2 forms the Flood Management Plan proper, with the necessary matrix of preparation, monitoring and response procedures and actions. This flood management plan and its supporting documents (see references below) fulfil the requirements of consent condition 7.1 including all items from 7.1a through 7.1g (Resource Consent 67173; 28 September 2016). This flood management plan is consistent with the Site Management Principles and the Flood Management Principles (reproduced below) that were identified in our January 2016 memo that now form the basis of the resource consent conditions relating to flood management.

    NOVEMBER 2017 B Ü ELER AND PFAHL 3567 Potential Vorticity Diagnostics to Quantify Effects of Latent Heating in Extratropical Cyclones. Part I: Methodology DOMINIK BÜELER AND STEPHAN PFAHL Institute for Atmospheric and Climate Science, ETH Zurich,€ Zurich, Switzerland (Manuscript received 9 February 2017, in final form 31 July 2017) ABSTRACT Extratropical cyclones develop because of baroclinic instability, but their intensification is often sub- stantially amplified by diabatic processes, most importantly, latent heating (LH) through cloud formation. Although this amplification is well understood for individual cyclones, there is still need for a systematic and quantitative investigation of how LH affects cyclone intensification in different, particularly warmer and moister, climates. For this purpose, the authors introduce a simple diagnostic to quantify the contribution of LH to cyclone intensification within the potential vorticity (PV) framework. The two leading terms in the PV tendency equation, diabatic PV modification and vertical advection, are used to derive a diagnostic equation to explicitly calculate the fraction of a cyclone’s positive lower-tropospheric PV anomaly caused by LH. The strength of this anomaly is strongly coupled to cyclone intensity and the associated impacts in terms of surface weather. To evaluate the performance of the diagnostic, sensitivity simulations of 12 Northern Hemisphere cyclones with artificially modified LH are carried out with a numerical weather prediction model. Based on these simulations, it is demonstrated that the PV diagnostic captures the mean sensitivity of the cyclones’ PV structure to LH as well as parts of the strong case-to-case variability. The simple and versatile PV diagnostic will be the basis for future climatological studies of LH effects on cyclone intensification.

  • Stop Log Flood Barriers
    PRODUCT STOP LOG FLOOD BARRIERS Flood Control International Incorporated offers removable stop log barriers that are engineered to provide similar levels of protection to permanent flood defenses, but with the distinct advantage of being fully removable when not required. They comprise aluminum panels that are inserted into steel channels. Custom made clamps compress specialist gaskets to create a reliable barrier against flood water. These stop log barriers can be supplied for virtually any configuration including arcs, closed rectangles or circles and straight runs of any length. The system can be used on slopes up to 20° and can be stepped for steeper gradients. USES Each system is load calculated based on application and the prevailing flood • Single building openings. conditions and can be configured for flood depths up to 13 feet.
