This Coastal and Hydraulics Engineering Technical Note (CHETN) describes coupling of the US Army Engineer Research and Development Center (ERDC) Wave Information System (WIS) database to Wavenet, the first module of MetOcnDat (Meteorological and Oceanographic Data or Metocean data) management and analysis system. Part 2 in the WaveNet technical note series provides a step-by-step procedure for users to access, process and analyze wave and wind data from the WIS database. Wilson et al. (2012) provided a detailed description of WaveNet in the Part 1 companion CHETN and demonstrated the utility of WaveNet for National Data Buoy Center (NDBC) wave data. WaveNet is a web-based Graphical-User-Interface (GUI) data management tool that allows users to access, process and analyze wave and wind data from different metocean data sources. TideNet is the next addition to the MetOcnDat system that will provide access and similar functionality for water level and current data. Once the user identifies a data need for a time interval, WaveNet performs data processing on-the-fly to check the availability, quality and consistency of data. It allows users to extract data to download, analyze and prepare input files for numerical wave models, and provides tabular and graphical information for project planning and design reports. WaveNet addresses a basic need of the Corps coastal modeling and planning missions by acquiring metocean data and providing analysis methods to minimize the complexity and uncertainty involved in data processing. This CHETN provides a guide for users to access the WIS database using WaveNet and step-by-step instructions that demonstrate processing and analysis of WIS data for project planning, design and evaluation studies, as well as the generation of input files for numerical wave models.
