Unlike previous investigations, which often limited the factors considered when applying ML methodologies to predict wave runup, this approach takes a holistic perspective. The analysis takes into account a comprehensive range of crucial coastal parameters, including the 2% exceedance value for runup, setup, total swash excursion, incident swash, infragravity swash, significant wave height, peak wave period, foreshore beach slope, and median sediment size. Model performance, interpretability, and practicality were assessed. The findings from this study showes that linear models, while valuable in many applications, proved insufficient in grasping the complexity of this dataset. On the other hand, we found that non-linear models are essential for achieving accurate wave runup predictions, underscoring their significance in the context of the research. Within the framework of this examination, it was found that wave runup is affected by median sediment size, significant wave height, and foreshore beach slope. Coastal engineers and managers can utilize these findings to design more resilient coastal structures and evaluate the risks posed by coastal hazards. To improve forecast accuracy, the research stressed feature selection and model complexity management. This research proves machine learning algorithms can predict wave runup, aiding coastal engineering and management. These models help build coastal infrastructure and predict coastal hazards.

İnşaat Mühendisliği alanının hata payının sıfıra yakın olma beklentisi ve insan yaşamına doğrudan etkisi sebebiyle bu bilgilerin bir inşaat mühendisi için kıymeti tartışılmazdır. Yapılacak çalışmada elde edilecek uzman bilgileri, işlenebilir bir ortamda biriktirilecek ve bilgisayar bilimleri alt alanı olan veri madenciliği teknikleri kullanılarak bulunulan koşullar altında inşaat mühendisine karar vermede yol gösterici olacaktır. En uygun malzeme ve yöntem tercihinde ışık tutması hedeflenen bu uzman sistemin aynı zamanda geri beslemeli olarak kendi kendini eğitebilmesi de hedeflenerek yeni laboratuar deneyleriyle elde edilen bilgilerle de gelişmesi hedeflenmektedir.

Both forms of failure have comparable ultimate circumstances, but the progression and sand movement mechanisms of breaching failure diverge from those of liquefaction. The first type, breaching, occurs in densely packed sand and is characterized by slow sand grain discharge throughout the dilation of the failing soil particles and negative excess pore pressures. The latter form, known as liquefaction, is the process by which a mass of soil abruptly begins to behave like a flowing liquid, and as a result, it can flow out across overly mild slopes. The process begins in compacted sand and is linked to positive surplus pore water pressures that are caused by the compaction of the sand. Despite the available literature on flow slide failures, our understanding of the mechanisms involved remains limited. Since flow slides often begin below the water surface, they can go undetected until the collapse reaches the...

Modelleme çalışmasında, deniz tabanı topoğrafyasının, hidrodinamik yüklerin, boru-zemin etkileşiminin, dalgaların ve akıntının borular üzerindeki etkileri ve risk değerlendirmesi örnek uygulamalar üzerinde yapılmıştır. Boruların darbelere karşı risk seviyeleri için, uygulamada kullanılan Det Norske Veritas (DNV) standartlarına göre yeni seviye önerileri sunulmuştur. Bu çalışmadaki amaç, literatürdeki diğer çalışmalardan farklı olarak deniz tabanındaki boruların hem düşeyde hem de yataydaki yer değiştirme risklerini değerlendirerek, boruların taşıdığı farklı hammaddelerin boru dengesi üzerine olan etkisini ortaya koymaktır. Ayrıca bu çalışmada, boru et kalınlıklarının güvenirlik üzerine etkisi hassasiyet analizi ile irdelenmiştir. Bu çalışmada endüstriyel boyutlu boruların tasarımına yönelik olup güvenilirliğe dayalı tasarımını içermektedir....

In coastal engineering, the most valuable data is wave behaviors. The amount of this data becomes very big because of observations that take place for periods of hours, days and months. In this study, some statistical methods such as the wave spectrum analysis methods and the standard statistical methods have been used. The goal of this study is the discovery profiles of the different coast areas by using these statistical methods, and thus, obtaining an instance based data set from the big data to analysis by using data mining algorithms. In the experimental studies, the six sample data sets about the wave behaviors obtained by 20 minutes of observations from Mersin Bay in Turkey and converted to an instance based form, while different clustering techniques in data mining algorithms were used to discover similar coastal places. Moreover, this study discusses that this sum...
