A new model is derived to predict the peak ground acceleration (PGA) utilizing a hybrid method coupling artificial neural network (ANN) and simulated annealing (SA), called SA-ANN. The proposed relates PGA earthquake source site distance, magnitude, average shear-wave velocity, faulting mechanisms, focal depth. database of strong ground-motion recordings 36 earthquakes, which happened in Iran's tectonic regions, used establish model. For more validity verification, SA-ANN employed part...
The projected changes in precipitation and air temperature over the Caspian Sea (CS) are studied using 13 Global Climate Models (GCMs) from Coupled Model Intercomparison Project Phase 6 (CMIP6) under four Shared Socioeconomic Pathways (SSPs) scenarios. Multi-Model Ensemble (MME) downscaling/bias-correction techniques applied to reduce uncertainties correct biases CMIP6 outputs. Future projections indicate a warmer climate (0.4–3°C) CS 21st century, with up 2.3% decrease or 20% increase based...
Sedimentation in ports and waterways covered with fine deposits is a significant challenge harbor management. The top layer of the bed such areas typically consists fluid mud, for which dredging complicated less efficient. goal this paper to investigate physical rheological characteristics sediment nautical depth assessment Bushehr Port its access channel. In study mud was detected by hydrographic surveys dual-frequency echo sounder. Moreover, properties various parts channel port were...
Abstract This study investigates some of the uncertainties sources associated with pseudo global warming (PGW) approach which was employed to project future patterns tropical cyclones (TCs) over Arabian Sea (AS). First, climate variables controlling were extracted from reanalysis datasets ERA5, ERAI, CFSR, and NCEP/NCAR. Then, each dataset evaluated against long‐term measurements identify best‐performing dataset. ERA5 showed best performance for most variables. Outputs 20 CMIP5 models (GCMs)...
Mashhadi, L.; Zaker, N.H.; Soltanpour, M., and Moghimi, S., 2015. Study of the Gonu tropical cyclone in Arabian Sea.The waves created Sea by have been simulated this paper employing Simulating Waves Nearshore (SWAN) third-generation spectral wave model. The model was established a nonstationary mode. linear exponential growth from wind input, wave–wave nonlinear interaction, whitecapping, bottom friction were considered simulation. results are compared with data measured at three stations on...
The combined effects of climate change and anthropogenic activities induce significant sea-level alterations, changing beach morphologies. While the water level rise on coastal regions have been extensively studied, consequences caused by fall, particularly in enclosed basins, received limited attention. Bruun rule is an empirical approach for estimating erosion sandy beaches response to sea rise. This study evaluates efficacy associated methods under water-level fall conditions. An...
Using several series of field measurements data along Iranian coastline the Persian Gulf and Oman, eight different tide models have been evaluated in this study. By comparing results frequency domain, it was found that model discrepancies arise shallow waters, having maximum error shallowest part Gulf, where Pohl station is located. On other hand, limited to 10 cm deeper indicating result close outcome waters. Considering time FES model, which includes more water constituents, better tidal...
The present study aims to simulate the various features of wave-mud interaction on finegrained shore profiles including wave height attenuation, wave-induced mud mass transport, gravity-driven flow fluid and reconfiguration profile shape. A two-dimensional beach deformation model is presented considering transport under continued action downward gravity force. transformation computed from energy flux conservation law combining effects bed, shoaling breaking. rheological constitutive...
