Abstract
Many streams in Scania have been regulated to increase the agricultural potential. Erosion of suspended particles and leakage of nutrients have increased, which gives a higher turbidity in streams. Water samples have been taken in Stream Segeå which has very turbid water. Samples have been taken both in the stream and inflowing ditches, to investigate where particles come from. The stream is very turbid from the beginning, directly after Lake Börringesjön, and has a high concentration of suspended particles. Ditches have lower turbidity and lower concentration of suspended particles. The concentration of nutrients and chlorophyll-a are also lower in the ditches than in the stream. The results show that Lake Börringesjön have a higher... (More)

The stream is very turbid from the beginning, directly after Lake Börringesjön, and has a high concentration of suspended particles. Ditches have lower turbidity and lower concentration of suspended particles. The concentration of nutrients and chlorophyll-a are also lower in the ditches than in the stream. The results show that Lake Börringesjön have a higher impact on the stream than ditches have, however more ditches have to be investigated. It is also important to take samples during other periods in the year, not only for some weeks in the spring. (Less)
