Abstract : This manual outlines a Wetland Evaluation Technique (WET) for the assessment of wetland functions and values. WET is a revision of the method developed for the Federal Highway administration (FHWA) that has often been referred to as the Federal Highway Method or the Adamus Method . Wetland functions are the physical, chemical, and biological characteristics of a wetland. Wetland evaluates the following functions and values: ground water stabilization, sediment/toxicant retention, nutrient removal/transformation, production export, wildlife diversity/abundance, aquatic diversity/abundance, uniqueness/heritage, and recreation. WET evaluates functions and values in terms of social significance, effectiveness, and opportunity. Social significance assesses the value of a wetland to society in terms of its special designations, potential economic value, and strategic location. Effectiveness assesses the capability of a wetland to perform a function because of its physical, chemical or biological characteristics. Opportunity assesses the opportunity of a wetland to perform a function to its level of capability. WET was designed primarily for conducting an initial, rapid assessment of wetland functions and values.
