USGS Techniques and Methods Reports (TM)
USGS Techniques and Methods (TM) reports describe procedures and standard methods for planning and executing studies and laboratory analyses. They are written for scientists. To find TM reports you can:
USGS Techniques of Water-Resources Investigations (TWRI)
USGS Techniques of Water-Resources Investigations (TWRI) reports are written for scientists and describe approved water-resources scientific and data-collection procedures and standard methods. This report series is no longer published; new water-resources techniques publications are published as part of the Techniques and Methods series (above).
Groundwater Technical Memoranda
Groundwater Technical Memoranda address USGS policy related to technical aspects of USGS groundwater studies and data collection.
Computer Modeling & Software
Building on decades of experience, the USGS continues to lead in the development and application of computer software to simulate groundwater flow and transport and to address scientific and management questions of increasing complexity. (For more information, see USGS Fact Sheet 2009-3105)
USGS groundwater software and supporting materials are in the public domain and can be downloaded from the USGS groundwater software page.
