Development of an uncertainty framework for contaminant and nutrient loads in rivers
Suspended sediments typically carry bound contaminants and nutrients and, therefore, affect the rivers’ water quality and ecosystem functioning. Concentrations of suspended solids and sediment-bound pollutants are monitored in many river systems worldwide. However, these monitoring programmes differ considerably in terms of monitoring techniques, measuring intervals and sampling locations within the river. This leads to uncertainties in load estimations around the globe. This thesis investigates the influence of sampling intervals on uncertainties in contaminant and nutrient loads, and derives how these uncertainties differ on a global scale.
