- Geostatistics - A branch of statistics focusing on spatial or spatiotemporal datasets
- Kriging - A group of geostatistical techniques to interpolate the value of a random field
- Top kriging - The method conceptualizes catchments as space-time filters and exploits the space-time correlations of runoff along the stream network topology.
Water Quality in a Spanish River (GLOBAQUA)
The River Ebro is the largest Mediterranean river in Spain and also one of the largest catchments in Europe. The river suffers from multiple stressors due to various land uses, such as farming, industry and urbanistation. These are impacting on the biota and ecological status of the river and the catchment. Real time water quality data taken from gauges along the river (shown on the cover picture from ArcGIS) will help to predict the status of the river in ungauged sections, and therefore improve management techniques.This 4 month project working with GLOBAQUA is the final part of my MSc at the University of Manchester (Applications in Environmental Science), and I will be spending this time at the Helmholtz Institute in Halle, Germany, where I will receive help and support from academics.
- To use R to interpolate water quality at ungauged sections of the River Ebro
- Specifically to use the rtop package based upon the top-kriging approach, to provide geostatistical interpolation
- To use ArcGIS to map the river catchment and data
- To improve management techniques in the Ebro in relation to water quality
- To improve the biota and ecological status of the river
