| Zusammenfassung |
| Measurements of pH, alkalinity and electrical conductivity
are used to examine the extent of the spatial and temporal variation in stream and ground water chemistry
for the Upper Severn catchment, Plynlimon. Wide temporal variations in stream waters broadly
reflect flow conditions and complex soil and ground water interactions but not soil type, land
usage or geology. The results have major implications for the use of critical load analysis
and the development and application of models in upland catchments. They point to the value
of field measurements for assessing the environmental management of upland catchments, rather
than the present use of over simplistic or inappropriate models. |
