Global warming has impacted the sea-level rise. Then it caused the Rob flooding in coastal areas. The research location is in Rob floods area in Tegalsari Hamlet, Jabon Subdistrict, Sidoarjo that have damaged seaweed cultivation, and estimated losses reached 5 billion rupiahs in early 2018. Therefore, it needs to do research numerical hydrodynamic models to prevent this flood. However, the devices for measurement data are too expensive. This research aims to utilise economical devices measurement based on the industrial revolution 4.0 with numerical hydrodynamic methods models in the field of civil engineering. This model is an approach to estimate the hydrodynamics of coastal waters such as tides, currents and water levels. To simulate the hydrodynamic model, for nearshore bathymetry data are gained from sonar and offshore bathymetry data from GEBCO. The simulations utilise open-source Delft3D software using the Navier-Stock formula. The outcomes prove that hydrodynamic simulation models can be used to estimate sea-level rise for the next few years in coastal areas. Thus, the determination of the type of construction of civil engineering buildings that are strong and environmentally friendly so that publics do not cause huge losses and make coastal communities resilient to disasters.

全球变暖影响了海平面上升。然后它在沿海地区引起了Rob洪水。研究地点位于 Sidoarjo Jabon 街道 Tegalsari Hamlet 的 Rob 洪水区，海藻种植受到破坏，估计 2018 年初损失达到 50 亿印尼盾。因此，需要研究数值水动力模型来防止这次洪水。然而，用于测量数据的设备过于昂贵。本研究旨在利用基于工业革命 4.0 的经济设备测量与土木工程领域的数值水动力方法模型。该模型是一种估计沿海水域流体动力学的方法，例如潮汐、洋流和水位。为了模拟水动力模型，近岸测深数据来自 GEBCO 的声纳和近海测深数据。模拟利用开源Delft3D软件使用 Navier-Stock 公式。结果证明，水动力模拟模型可用于估计沿海地区未来几年的海平面上升。因此，确定坚固且环保的土木工程建筑的建筑类型，以使公众不会造成巨大损失，并使沿海社区具有抗灾能力。
