Water Resources Research, Volume 62, Issue 10, October 2026.Abstract Physics‐informed neural networks (PINNs) provide a promising framework for river hydrodynamic simulation and parameter inversion under sparse observations. However, spatial heterogeneity in channel geometry and roughness causes strong variations in flood‐wave propagation and parameter sensitivity, challenging local conservation and joint state‐

SAINT-VENANT TYPE ESTIMATE FOR THE WAVE EQUATION
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2002 Bu çalışmada hızı azalan bir dalga denklemi için Uzaysal Azalım Kestirimi elde edilmiştir. Yük bölgesinden uzaklaşıldıkça son etkilerin, en azından kısa zaman aralıkları için çok hızlı bir şekilde azaldığı görülmüştür.
