  • Mitigation of Channel Shoaling at a Sheltered Inlet Subject to Flood Gate Operations
    Journal of Marine Science and Engineering Article Mitigation of Channel Shoaling at a Sheltered Inlet Subject to Flood Gate Operations Laura Lemke * , Matthew S. Janssen and Jon K. Miller Coastal Engineering Research Group, Davidson Laboratory, Stevens Institute of Technology, Hoboken, NJ 07030, USA; [email protected] (M.S.J.); [email protected] (J.K.M.) * Correspondence: [email protected] Received: 30 September 2020; Accepted: 29 October 2020; Published: 31 October 2020 Abstract: A comprehensive case study of Keansburg Inlet (New Jersey, USA) is presented with the objective of evaluating inlet management alternatives and assessing the influence of an operational flood gate on channel shoaling. The goal of the research is determining the most effective strategy for minimizing the frequency of maintenance dredging. This study compares the effectiveness of (1) traditional structural solutions; (2) modified dredging templates; and (3) assesses the influence of the flood gate operations during conditions representative of a typical year. Alternative analysis is completed using a coupled hydrodynamic–wave model (Delft3D-Flexible Mesh (FM)) with Real Time Control to simulate morphological changes. The model was calibrated and evaluated using collected field data. Water levels are reproduced within 6% of the spring tide range with lag times less than 20 min. The model results and observations suggest sediment transport is dominated by wave action with pronounced variations in dominant wave direction. The results indicate that changes to the operational dredging, or what the authors have termed broadly as “adaptive dredging techniques”, appear to deliver the most promising improvement. Model results suggest that the current operational procedures of the flood gate do not significantly alter the channel infilling rates and patterns during typical (i.e., non-extreme event) conditions.

  • Impacts of Long Jetties Construction on Shoreline Change at the Western Coast of the Gulf of Thailand
    Article Impacts of Long Jetties Construction on Shoreline Change at the Western Coast of the Gulf of Thailand Nathamon Phanomphongphaisarn.1,2,a, Chaipant Rukvichai1,b, and Butsawan Bidorn1,2,c,* 1 Department of Water Resource Engineering, Chulalongkorn University, Bangkok, Thailand 2 WISE Research Unit, Chulalongkorn University, Bangkok, Thailand E-mail: [email protected], [email protected], cbutsawan.p @chula.ac.th (Corresponding author) Abstract. Pranburi Jetties, a pair of long jetties with a length of 800 m and 860 m, have been constructed at the Pranburi River inlet, located on the western coast of the Gulf of Thailand since 1999 to stabilize the river mouth. The purposes of this study were to evaluate the responses of shoreline due to the construction of Pranburi Jetties, and the accuracy of the One-Line model (OLM) on predicting the shoreline change due to construction. Based on the shoreline positions retrieving from aerial photographs and satellite imagery during 1967- 2018, the difference in shoreline evolution before and after the construction of the jetties was evaluated using ArcGIS and Digital Shoreline Analysis System. The predicted shorelines using the One-Line model were compared with the image-analyzed shorelines for evaluating the accuracy of the model. The results indicated that the construction of Pranburi Jetties had caused the shoreline accretion at the vicinity of the jetties with the maximum accretion of up to 300 m in 2018. The land growth of 16.2 and 9 ha took place at the northern and southern coasts, respectively. The percentage of errors between the predicted and the image- analyzed shoreline varied from 2 to 13,000 percent with an average of 250 percent.

  • Large Scale Impacts of Jetties and Training Walls - Experience on the Australian East Coast
    LARGE SCALE IMPACTS OF JETTIES AND TRAINING WALLS - EXPERIENCE ON THE AUSTRALIAN EAST COAST Angus Gordon, Coastal Zone Management and Planning, [email protected] Alexander Nielsen, Advisian Worley Group, [email protected] INTRODUCTION The erosion has continued due to both the realignment of Entrance jetties and training walls have instigated the beach and the net loss of sand blown into the dunes fundamental perturbations to coastal and estuary of Newcastle Bight (Gordon & Roy, 1977). This has processes at several locations on the Australian eastern resulted in the requirement to construct a rock revetment seaboard inducing long term changes to foreshore to protect Mitchell Street and the village (Figure 2). More alignments, tidal current velocities, tidal plane elevations recently it has been necessary to undertake beach and marine ecologies with significant consequences, nourishment to offset the on-going coastal recession. some having been realised only recently. This paper presents examples of long-term impacts of entrance jetties and training walls on coastal and estuary processes, gleaned from experience on the NSW coast. COASTALPROCESSES On coastlines with high transport rates of littoral drift, jetties have trapped sand inducing erosion on down-drift beaches at the Tweed River (Delft 1970) and Coffs Harbour (Lord & van Kerkvoort 1981). Another less-appreciated impact of jetties on coastal alignments has been the changes they can induce in near-shore wave patterns that, in turn, will re-align ocean Figure 1 - Left: Entrance to Newcastle Harbour (circa foreshores significantly (Miller & Nielsen 1995, Klein et al. 1850).

  • Impacts of Jetty Construction on the Wave Heights Off the Kiashahr Lagoon S
    Impacts of jetty construction on the wave heights off the Kiashahr lagoon S. A. Azarmsa,1∗ M. Esmaeili,2 and A. Karami Khaniki3 1Faculty of Marine Sciences, Tarbiat Modares University, Gisha, Tehran, Iran 2Faculty of Marine Sciences, Chabahar Maritime University, Chabahar, Iran 3Soil Conservation and Watershed Management Research Center, Tehran, Iran ∗Corresponding author: [email protected] Coastal managers and ecologists are confronted with tasks to estimate wave heights in the Kiashahr sea area, since hydrodynamic factors can profoundly impact this environment. In this study, wind data and an empirical wind wave predicting model were used to estimate deepwater wave characteristics in the Kiashahr sea area; while a numerical model was used to determine wave characteristics in shallow waters. Wave heights were also determined and compared at different stations before and after construction of 2 jetties at the lagoon mouth to evaluate their efficiency in wave height reduction. Results revealed that wave height is in the range of 0.8 to 1.2 m at Sefid Rud river mouth. Significant wave height reduction in the range of 0.15 to 1.2 m occurred at the entrance of the lagoon due to construction of the jetties. This attenuation of wave energy may result in some impacts on the ecosystem health of Kiashahr lagoon such as increased sedimentation, reduction in flushing rates, dumping of garbage and consequently, more pollution. Keywords: wind, Caspian Sea, Iran Introduction into a bay with broad entrance to the sea and exposed it to more energetic waves, similar to the situation Sustainable management of aquatic ecosystems in the 1950s.

  • Deconstructing a Jetty to Rectify the Downdrift Erosion
    Journal of Sustainability Science and Management eISSN: 2672-7226 Volume 15 Number 2, February 2020: 79-88 © Penerbit UMT DECONSTRUCTING A JETTY TO RECTIFY THE DOWNDRIFT EROSION CHERDVONG SAENGSUPAVANICH Faculty of International Maritime Studies, Kasetsart University, Sri Racha Campus, 199 Moo 6 Sukhumvit Rd., Tungsukla, Sri Racha, Chonburi, 20230, Thailand. *Corresponding author: [email protected] Abstract: A jetty is a coastal structure constructed across the surf zone to prevent sediment deposition at a river mouth. It creates updrift accumulation and downdrift erosion. Deconstructing the jetty may restore the situation but create another problem. This study used the Cha-am beach in Thailand to simulate future shoreline positions under different scenarios. The main tool used in the study was the software package LITPACK. The calibrated simulations showed that, if no action was taken, the updrift part of the beach would be widened by as much as 130 m in 25 years but the downdrift side of the jetty would experience severe coastal erosion. Deconstructing the jetty would alternate the outcome. The area where the erosion was foreseen along the downdrift shoreline would not occur anymore. The sediment once intercepted by the jetty would move to pass the inlet. However, the updrift shoreline would adjust its alignment, eroding existing houses and other buildings. While jetty deconstruction would restore the downdrift part of the beach, it would at the same time destroy some properties along the updrift section. Removing the jetty may experience great social resistance. Decision- makers should be equipped with adequate information and coastal engineering can provide some necessary inputs.
