Abstract
Understanding and taking account of dynamics in water quality is
essential for adequate water quality policy and management. In
conventional regional surface water and upper groundwater quality
monitoring, measurement frequencies are too low to capture the
short-term dynamic behavior of solute concentrations. In this
presentation, we demonstrate that neglecting the dynamics in water
quality leads to inefficient water quality monitoring and inadequate
water resources management. In a multi-scale catchment monitoring study,
we demonstrated the value of in-situ analyzers for continuous
concentration measurements. Our on-site equipment performed
semi-continuous (15 min interval) NO3 and P concentration measurements
and recorded the concentration responses to rainfall events with a wide
range in antecedent conditions and rainfall durations and intensities.
We used these measurements to (1) unravel nutrient transport processes,
(2) evaluate and optimize a new passive sampling technique for measuring
average concentrations, and (3) to develop and evaluate options to
exploit the explanatory strength of commonly available continuous
measurements of quantitative hydrological parameters like precipitation,
discharge, and groundwater levels.
