Wave attenuation is a key process that impacts activities at the coastal land margin and is an ecosystem service provided by many natural landscapes. Traditional modeling tools for wind wave attenuation require advanced expertise to apply. We present an alternative, GIS-based option for estimating wave attenuation, the Wave Attenuation Toolbox (WATTE). The outputs are a map of wave height transmission as a percentage of the original wave height and a line demarking the extent of wave exposure onshore. WATTE supports a variety of inputs, ranging from outputs of ecological and landscape evolution models to remote sensing data, and past, present, and future conditions can be analyzed. The present version of WATTE models wave attenuation as an exponential decay process, and a recommendation table for exponential decay constants is derived from previous studies. Three examples of applying WATTE to marsh environments are described.

波浪衰减是影响沿海陆地边缘活动的关键过程，并且是许多自然景观提供的生态系统服务。传统的风波衰减建模工具需要高级专业知识才能应用。我们提出了一种基于GIS的替代方法，用于估计波衰减，即波衰减工具箱（WATTE）。输出是波高传输率（占原始波高的百分比）的图，以及表示在岸上波暴露程度的线。WATTE支持各种输入，从生态和景观演化模型的输出到遥感数据，可以分析过去，现在和将来的状况。当前版本的WATTE将波衰减建模为指数衰减过程，从以前的研究中得出了指数衰减常数的推荐表。描述了将WATTE应用于沼泽环境的三个示例。
