Suitability Test for Groundwater Monitoring Points ++ PDF file ++
This standard W 129 applies to the testing of the correct operation and suitability, hereinafter referred to as ”suitability test“, of existing groundwater monitoring points.
Design and Construction of Groundwater Monitoring Points ++ PDF file ++
This Code of Practice W 121 applies to the design and construction of groundwater monitoring points for monitoring the quality and quantity of groundwater in solid rocks and granular soil.
Guidance for the Application of Numerical
This Code of Practice W 107 shall apply to the establishment and application of numerical groundwater flow and transport models in water catchment areas.
Forest Management and Water Resources Protection ++ PDF file ++
This guideline W 105 describes the facts and measures of water-protecting forest management. This guideline is aimed at forest owners, dam operators and water utilities as well as water management and forestry authorities.
Determination of gravel-pack diameter and hydrogeological analysis of grain size distribution for purposes of well construction ++ PDF file ++
The Technical Standard W 113 shall apply to the determination of the required gravel-pack diameter for the filter section during the construction of wells in granular soils.
Planning, Execution and Analysis of Pumping Tests in Groundwater Development ++ PDF file ++
Since the publication of the 1997 edition of W 111, more experience has been gained, more findings have been made and new methods have been developed for executing and analysing pumping tests as well as for the electronic capture of data at optional intervals. The measurement behaviour of groundwater data loggers can now be programmed much more extensively; moreover, they can now transmit the collected data via radio-based systems like GSM or GRPS either immediately or according to a predefined schedule. This Code of Practice discusses the resultant opportunities for quality assurance and the analysis of the frequently very elaborate tests.
