Accurate modelling of constructed wetlands is vital for furthering the use of these systems. Constructed wetlands can treat various types of wastewater, including domestic wastewater, agricultural wastewater, industrial and mining wastewater and stormwater runoff. Physical, chemical and biological processes all take place simultaneously to breakdown the contaminants in wastewater, and while the combination of so many processes makes them an effective wastewater treatment system, it can also make the modelling of these systems intricate. The modelling technique used is dependent on the goal of the model, whether it is for design or scientific research. The extent to which contaminants are broken down by these processes is highly dependent on the time the water spends in the system, and this time is dependent on and can be quantified by the understanding of the hydraulic behaviour of the constructed wetland. Tracer studies are the most common way to determine the hydraulic behaviour of the system and the data from these studies can be used in various ways to quantify time in the system. There are three aims of this paper, the first is to give wetland researchers an idea of what hydraulic modelling techniques are available, the second is to indicate the connection between accurate hydraulic modelling and the modelling of kinetic processes, and the third is to guide the researchers in determining which model is best suited for their needs based on research needs and characteristics of the wetland.

人工湿地的精确建模对于进一步使用这些系统至关重要。人工湿地可以处理各种类型的废水，包括生活废水，农业废水，工业和采矿废水以及雨水径流。物理，化学和生物过程都同时发生，以分解废水中的污染物，尽管如此多的过程相结合，使它们成为有效的废水处理系统，但也可以使这些系统的建模变得复杂。所使用的建模技术取决于模型的目标，无论是用于设计还是用于科学研究。这些过程将污染物分解的程度在很大程度上取决于水在系统中所花费的时间，这个时间取决于对人工湿地水力行为的了解，并可以通过对其进行量化。示踪剂研究是确定系统水力行为的最常用方法，这些研究中的数据可以多种方式用于量化系统中的时间。本文有三个目标，第一个是让湿地研究人员了解可用的水力建模技术，第二个是指出精确的水力建模与动力学过程建模之间的联系，第三个是指导水力学建模。研究人员根据研究需求和湿地特征确定哪种模型最适合他们的需求。示踪剂研究是确定系统水力行为的最常用方法，这些研究中的数据可以多种方式用于量化系统中的时间。本文有三个目标，第一个是让湿地研究人员了解可用的水力建模技术，第二个是指出精确的水力建模与动力学过程建模之间的联系，第三个是指导水力学建模。研究人员根据研究需求和湿地特征确定哪种模型最适合他们的需求。示踪剂研究是确定系统水力行为的最常用方法，这些研究中的数据可以多种方式用于量化系统中的时间。本文有三个目标，第一个是让湿地研究人员了解可用的水力建模技术，第二个是指出精确的水力建模与动力学过程建模之间的联系，第三个是指导水力学建模。研究人员根据研究需求和湿地特征确定哪种模型最适合他们的需求。
