We estimated the changes in the losses of particulate and dissolved phosphorus (P) after treating 93 ha of agricultural fields with gypsum (4 t ha–1) in a 245 ha catchment in southern Finland. Runoff was monitored using online sensors and manual sa

Wetlands play an important role in reducing nutrient loads to receiving waters. The efficiency of a wetland in nutrient removal is commonly evaluated from discrete water samples taken at the inflow and at the outflow of the target wetland. In order t

A low altitude aerial infrared (AIR) survey was conducted to identify hydraulic connections between aquifers and rivers, and to map spatial surface temperature patterns along boreal rivers. In addition, the stable isotopic compositions (δ18O, δD),

Urbanization changes water balance, degrades water quality and disrupts habitats. Wetlands offer storm water volume and flow control, water pollution mitigation, and rich land–water interphase habitats. In the present case study, urban wetlands wer

Perinteinen syyskynnetty viljely jättää pellot osaksi vuotta ilman kasvipeitettä, jolloin ne ovat alttiina sateen ja sulamisvesien aiheuttamalle maa-aineksen huuhtoutumiselle. Pääosa vuoden kiintoaine- ja ravinnekuormituksesta kulkeutuu vesist
