Abstract

Tidal inlet structures are engineering projects with associated benefits related to flood control, water quality enhancement, and coastal protection. This study analyzes the performance of hydraulic gates on a stabilized inlet in estuarine systems by developing a simplified hydraulic model that considers inlet and outlet water levels. The proposed model was applied to the stabilized tidal inlet structure in Cartagena de Indias, Colombia. This model offers a practical tool for engineers and designers operating estuarine systems. The analysis focuses on the coastal lagoon of Ciénaga de la Virgen. The proposed model was successfully calibrated using two water sensors, with extreme input and outlet flow rates of approximately 260 m3/s and 110 m3/s, respectively. The average daily output volume in the system is 3,361,000 m3, while the average daily input volume is 3,200,000 m3. Consequently, the manipulation of the opening gates results in a decrease in the estuarine water level, potentially by as much as 25 cm, which local authorities can use to make decisions to reduce extreme water levels during flooding events.

水力闸门对稳定潮汐入口结构的影响分析：数学模型和数据测量

潮汐入口结构是一个工程项目，具有防洪、提高水质和海岸保护等相关效益。本研究通过建立一个考虑进水口和出水口水位的简化水力模型，分析了河口系统中稳定进水口水力闸门的性能。提出的模型适用于哥伦比亚卡塔赫纳德印第亚斯的稳定潮汐入口结构。该模型为河口系统的工程师和设计师提供了一个实用工具。分析的重点是 Ciénaga de la Virgen 沿海泻湖。使用两个水传感器成功校准了所提出的模型，输入和输出的极端流量分别约为 260 立方米/秒和 110 立方米/秒。该系统的日平均输出量为 3,361,000 立方米，而日平均输入量为 3,200,000 立方米。因此，控制闸门的开启会导致河口水位下降，降幅可能高达 25 厘米，地方当局可据此做出决策，以降低洪灾期间的极端水位。

期刊介绍： Journal of Hydrology publishes original research papers and comprehensive reviews in all the subfields of the hydrological sciences, including water based management and policy issues that impact on economics and society. These comprise, but are not limited to the physical, chemical, biogeochemical, stochastic and systems aspects of surface and groundwater hydrology, hydrometeorology, hydrogeology and hydrogeophysics. Relevant topics incorporating the insights and methodologies of disciplines such as climatology, water resource systems, ecohydrology, geomorphology, soil science, instrumentation and remote sensing, data and information sciences, civil and environmental engineering are within scope. Social science perspectives on hydrological problems such as resource and ecological economics, sociology, psychology and behavioural science, management and policy analysis are also invited. Multi-and interdisciplinary analyses of hydrological problems are within scope. The science published in the Journal of Hydrology is relevant to catchment scales rather than exclusively to a local scale or site. Studies focused on urban hydrological issues are included.
