- | == Problemstellung == | ||
- | Stable isotopes of water are one of the most widely used tools to track the pathways of precipitation inputs through soils to streams. In the past, soils have often been treated as black-boxes through which precipitation is routed to streams without much consideration of how, when, and where water is transported along soil water flow paths. In fact, precipitation reaches the forest floor via diffuse (throughfall) and point (stem flow) inputs and throughfall can be highly heterogeneous, | ||

- | The aim of this thesis is to use stable isotopes of water (< | ||
- | |||
- | == Methode == | ||
- | To track the precipitation isotopic input through the canopy, over the soil to the stream, different types of samplers should be setup and several rainfall events should be monitored. Soil samples should be taken by coring and water extraction should be performed. The isotopic composition of lateral and vertical subsurface flow and streamflow should be monitored. The subsequent isotope analysis will be done in our lab. | ||
