Özet:

 In this study, the applicability of the approach known as sparse identification of nonlinear dynamics SINDy for the simulation of the mechanisms controlling coastal and harbor hydrodynamic processes was examined. The main goal of the SINDy approach is to use ordinary differential equations ODEs with as few sparse components as possible to describe the drift trajectories of particles and objects determined by computational or measurement techniques. Using Lagrangian drift device data obtained using a floating buoy in the Caribbean Sea in the Atlantic Ocean, the possible use of the drift route and time series of the SINDy algorithm with and without trigonometric terms to model hydrodynamic effects in coastal and harbor hydrodynamics is investigated. It has been shown that Lagrangian drifter equations can be reconstructed from data with SINDy. It has been suggested that, for specified types of events and disasters, the SINDy-based algorithmic technique can reliably and quickly estimate the coastal and harbor hydrodynamic equations specific to a region. An evaluation of possible study areas, usage areas, and practical applications of our findings is also included.

 Bu çalışmada, doğrusal olmayan dinamiklerin seyrek tanımlanması veya SINDy sparse identification of nonlinear dynamics olarak bilinen yaklaşımın, kıyı ve liman hidrodinamik süreçlerini kontrol eden mekanizmaların benzeşimi için uygulanabilirliği incelenmiştir. SINDy yaklaşımının temel amacı, hesaplamalı veya ölçüm teknikleriyle belirlenen parçacıkların ve nesnelerin sürüklenme rotalarını açıklamak için mümkün olan en az seyrek bileşenli adi diferansiyel denklemleri ADD kullanmaktır. Atlas Okyanusunda Karayip Denizinde yüzen bir şamandıra kullanılarak elde edilen Lagrange sürüklenme cihazı verilerinden yararlanılarak, sürüklenme rotası ve zaman serilerinin SINDy algoritmasının trigonometrik bileşenlerinin hem olması hem de olmaması durumlarında kıyı ve liman hidrodinamiğindeki hidrodinamik etkileri modellemek için olası kullanımı araştırılmıştır. SINDy ile Lagrange sürüklenicisi denklemlerinin verilerden geriçatılabileceği gösterilmiştir. Belirlenen türden olay ve afetlerde, SINDy tabanlı algoritmik tekniğin, bir bölgeye özgü kıyı ve liman hidrodinamiği denklemlerini güvenilir ve hızlı bir şekilde tahmin edebileceği önerilmiştir. Ayrıca bulgularımızın olası çalışma alanları, kullanım konuları ve pratik uygulamalarına ilişkin bir değerlendirmeye de yer verilmiştir.
