Tsunamis in shallow water zones lead to sea water level rise and fall, strong currents, forces (drag, impact, uplift, etc.), morphological changes (erosion, deposition), dynamic water pressure, as well as resonant oscillations. As a result, ground materials under the tsunami motion move and scour/erosion/deposition patterns can be observed in the region. Ports and harbours as enclosed basins are the main examples of coastal structures that usually encounter natural hazards with small or huge damaging scales. Morphological changes are one of the important phenomena in the basins under short and long wave attack. Tsunamis as long waves lead to sedimentation in the basins, and therefore, in this study, the relation to the current pattern is noticed to determine sedimentation modes. Accordingly, we present a methodology based on the computation of the instantaneous Rouse number to investigate the tsunami motion and to calculate the respective sedimentation. This study aims to investigate the effects of the incident wave period on Antalya Belek region is selected as a case study sedimentation, NAMI DANCE, which solves non-linear shallow water equations. The results showed that the corner points on the bending part of the basin are always the critical points where water surface elevation and current velocity amplify in the exterior and interior corners, respectively.

Effects of Harbor Shape on the Induced Sedimentation; L-Type Basin Kian, Rozita; Velioglu, Deniz; Yalçıner, Ahmet Cevdet; Zaytsev, Andrey (2016-09-01) Tsunamis in shallow water zones lead to sea water level rise and fall, strong currents, forces (drag, impact, uplift, etc.), morphological changes (erosion, deposition), dynamic water pressure, as well as resonant oscillations. As a result, ground materials under the tsunami motion move, and scour/erosion/deposition patterns can be observed in the region.

Impacts of atmospheric nutrient deposition on marine productivity: Roles of nitrogen, phosphorus, and iron Okin, Gregory S.; Baker, Alex R.; Tegen, Ina; Mahowald, Natalie M.; Dentener, Frank J.; Duce, Robert A.; Galloway, James N.; Hunter, Keith; Kanakidou, Maria; Kubilay, Nilgun; Prospero, Joseph M.; Sarin, Manmohan; Surapipith, Vanisa; Uematsu, Mitsuo; Zhu, Tong (American Geophysical Union (AGU), 2011-06-23) Nutrients are supplied to the mixed layer of the open ocean by either atmospheric deposition or mixing from deeper waters, and these nutrients drive nitrogen and carbon fixation. To evaluate the importance of atmospheric deposition, we estimate marine nitrogen and carbon fixation from present-day simulations of atmospheric deposition of nitrogen, phosphorus, and iron. These are compared with observed rates of marine nitrogen and carbon fixation. We find that Fe deposition is more important than P deposition...
Diagnosing Neglected Soil Moisture Source-Sink Processes via a Thermal Infrared-Based Two-Source Energy Balance Model Hain, Christopher R.; Crow, Wade T.; Anderson, Martha C.; Yılmaz, Mustafa Tuğrul (American Meteorological Society, 2015-06-01) In recent years, increased attention has been paid to the role of previously neglected water source (e.g., irrigation, direct groundwater extraction, and inland water bodies) and sink (e.g., tile drainage) processes on the surface energy balance. However, efforts to parameterize these processes within land surface models (LSMs) have generally been hampered by a lack of appropriate observational tools for directly observing the impact(s) of such processes on surface energy fluxes. One potential strategy for ...
Effect of axial stresses on reservoir rocks Kök, Mustafa Verşan; Buket Ulker, E. (2002-10-01) The effect of axial stresses on rock is known to affect porosity, permeability, and rock compressibility and will be important in some reservoir rock types that are buried deep and at high temperatures. The aim of this project is to determine reservoir rock properties under in situ stress conditions and to observe the effects of axial stresses on reservoir rocks. For this purpose, a uniaxial stress device, which is capable of applying axial stress to the core samples, was used. The core samples chosen were ...
Effects of implementing MODIS land cover and albedo in MM5 at two contrasting US regions Yücel, İsmail (American Meteorological Society, 2006-10-01) This study implements a new land-cover classification and surface albedo from the Moderate Resolution Imaging Spectroradiometer (MODIS) in the fifth-generation Pennsylvania State University-National Center for Atmospheric Research (PSU-NCAR) Mesoscale Model (MM5) and investigates its effects on regional near-surface atmospheric state variables as well as the planetary boundary layer evolution for two dissimilar U.S. regions. Surface parameter datasets are determined by translating the 17-category MODIS clas...
