作文

Understanding the term mean lower high water is essential for those involved in maritime activities, environmental studies, and coastal management. This phrase refers to a specific measurement used in tidal studies, particularly in the context of navigation and land use planning. The mean lower high water (MLHW) is defined as the average height of the higher of the two high tides observed over a specific period, usually 19 years. This metric is crucial because it helps determine the baseline for various activities along the shoreline, including construction, dredging, and habitat conservation.In coastal regions, accurate knowledge of the mean lower high water level is vital for several reasons. Firstly, it assists in the planning and design of coastal infrastructure. Engineers and architects must consider the MLHW when constructing buildings, roads, or other structures near the shore. If these constructions are built below the MLHW line, they risk damage from flooding during high tides or storm surges.Secondly, the mean lower high water level serves as a reference point for environmental protection efforts. Coastal ecosystems, such as wetlands and estuaries, are sensitive to changes in water levels. By understanding the MLHW, environmentalists can assess the health of these ecosystems and make informed decisions about conservation practices. For instance, if the MLHW level rises due to climate change, it may indicate that certain habitats are at risk and require immediate attention.Moreover, the mean lower high water measurement is also important for navigation. Mariners rely on accurate tidal data to ensure safe passage through coastal waters. Knowing the MLHW helps in determining safe anchorage areas and avoiding shallow spots that could pose a hazard to vessels. Inaccurate tidal information can lead to grounding incidents, which can be costly and dangerous.In addition to its practical applications, the concept of mean lower high water highlights the intricate relationship between human activities and natural processes. As sea levels rise due to climate change, the MLHW may shift, impacting everything from local economies to wildlife habitats. This necessitates ongoing monitoring and adaptation strategies to mitigate potential risks associated with rising tides.In conclusion, grasping the significance of mean lower high water is crucial for various stakeholders, including urban planners, environmentalists, and mariners. It serves as a fundamental reference point that influences coastal development, environmental conservation, and navigation safety. As we face the challenges posed by climate change, understanding and adapting to changes in the MLHW will be essential for sustainable coastal management and protecting our valuable marine ecosystems.

理解术语mean lower high water对于参与海洋活动、环境研究和沿海管理的人士至关重要。这个短语指的是在潮汐研究中使用的特定测量，尤其是在航行和土地使用规划的背景下。mean lower high water（MLHW）被定义为在特定时期内（通常为19年）观察到的两个高潮中的较高者的平均高度。这个指标至关重要，因为它有助于确定沿海岸线进行各种活动的基准，包括建筑、疏浚和栖息地保护。在沿海地区，准确了解mean lower high water水平对多个原因至关重要。首先，它有助于沿海基础设施的规划和设计。工程师和建筑师在靠近海岸建造建筑物、道路或其他结构时，必须考虑MLHW。如果这些建筑在MLHW线以下建造，它们就会面临在高潮或风暴潮期间遭受洪水破坏的风险。其次，mean lower high water水平作为环境保护工作的参考点。沿海生态系统，如湿地和河口，对水位变化非常敏感。通过了解MLHW，环境保护人士可以评估这些生态系统的健康状况，并做出明智的保护决策。例如，如果由于气候变化，MLHW水平上升，这可能意味着某些栖息地处于危险之中，需要立即关注。此外，mean lower high water测量也对航行非常重要。海员依赖准确的潮汐数据来确保安全通过沿海水域。知道MLHW有助于确定安全的锚泊区并避免可能对船只构成危险的浅水区。不准确的潮汐信息可能导致搁浅事件，这可能是昂贵且危险的。除了其实际应用外，mean lower high water的概念突显了人类活动与自然过程之间错综复杂的关系。随着气候变化导致海平面上升，MLHW可能会发生变化，影响从地方经济到野生动物栖息地的方方面面。这需要持续监测和适应策略，以减轻与潮水上升相关的潜在风险。总之，掌握mean lower high water的重要性对于城市规划者、环境保护人士和海员等各种利益相关者至关重要。它作为一个基本参考点，影响沿海开发、环境保护和航行安全。随着我们面临气候变化带来的挑战，理解和适应MLHW的变化将对可持续的沿海管理和保护我们宝贵的海洋生态系统至关重要。
