High-resolution monitoring of nutrients in groundwater and surface waters: process understanding, quantification of loads and concentrations, and management applications

| Summary: | Four sessions on "Monitoring Strategies: temporal trends in groundwater and
surface water quality and quantity" at the EGU conferences in 2012, 2013,
2014, and 2015 and a special issue of <i>HESS</i> form the background for this
overview of the current state of high-resolution monitoring of nutrients. The
overview includes a summary of technologies applied in high-frequency
monitoring of nutrients in the special issue. Moreover, we present a new
assessment of the objectives behind high-frequency monitoring as classified
into three main groups: (i) improved understanding of the underlying
hydrological, chemical, and biological processes (PU); (ii) quantification of
true nutrient concentrations and loads (Q); and (iii) operational management,
including evaluation of the effects of mitigation measures (M). The
contributions in the special issue focus on the implementation of high-frequency monitoring within the broader context of policy making and
management of water in Europe for support of EU directives such as the Water
Framework Directive, the Groundwater Directive, and the Nitrates Directive.
The overview presented enabled us to highlight the typical objectives
encountered in the application of high-frequency monitoring and to reflect on
future developments and research needs in this growing field of expertise. |
