Main Description

  • The rural Kielstau catchment (50 km²) is located in northern Germany in a lowland area.
  • The Kielstau river’s water quality is strongly influenced by agriculture. Land use is dominated by grain, corn, rape and pasture; 38% of agricultural land is artificially drained (Fig.1).
  • The Kielstau river is part of the flora fauna habitat directive (92/43/CEE), and nature conservation areas are used for moderate grazing.

This table presents the different categories of ecosystem services that ecosystem can provide, divided in:

Provisioning Services are ecosystem services that describe the material or energy outputs from ecosystems. They include food, water and other resources.

Food: Ecosystems provide the conditions for growing food. Food comes principally from managed agro-ecosystems but marine and freshwater systems or forests also provide food for human consumption. Wild foods from forests are often underestimated.


Raw materials: Ecosystems provide a great diversity of materials for construction and fuel including wood, biofuels and plant oils that are directly derived from wild and cultivated plant species.

Regulating Services are the services that ecosystems provide by acting as regulators eg. regulating the quality of air and soil or by providing flood and disease control.

Erosion prevention and maintenance of soil fertility: Soil erosion is a key factor in the process of land degradation and desertification. Vegetation cover provides a vital regulating service by preventing soil erosion. Soil fertility is essential for plant growth and agriculture and well functioning ecosystems supply the soil with nutrients required to support plant growth.

Ecosystem services "that are necessary for the production of all other ecosystem services". These include services such as nutrient recycling, primary production and soil formation.

Habitats for species: Habitats provide everything that an individual plant or animal needs to survive: food; water; and shelter. Each ecosystem provides different habitats that can be essential for a species’ lifecycle. Migratory species including birds, fish, mammals and insects all depend upon different ecosystems during their movements.

Cultural Services corresponds nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experiences.

EH Principles

Quantification of the hydrological processes at catchment scale and mapping the impacts

Distribution of ecosystems and their relevant processes (ex: metabolism=water and nutrient uptake and retention; biomass production)

Ecological engineering (integration, dual regulation and biotechnologies in catchment scale for enhancement of ecological potential)

ECOHYDROLOGY ENGINEERING SOLUTIONS

Renaturalisation of river sections and riparian wetlands

Phytotechnology

Building and testing of reactive ditches (Fig.2) and retention ponds

Ecohydrological Infrastructure

River basin model; Hydraulic models; Species distribution model (SWAT; HEC-RAS; ADH; BIOMOD)

Hydrological Flow

Major Issues

  • Ecological status of the stream needs to be improved
  • Nutrient (nitrogen and phosphorus) and pesticide loads due to agricultural activities

    Latest Results

    • There is a strong impact of shallow groundwater with intensive interactions between groundwater and surface water. Due to artificial drainage systems, the area is influenced by fast water transport (Schmalz et al., 2008, Kiesel et al., 2010, Pfannerstill et al., 2014).

    • Integrated ecohydrological modelling by using hydrologic, hydraulic and biological data helps assessing aquatic habitats and ecosystems (Kiesel et al., 2009, 2013, 2015). A moderate ecological status was calculated by using biological indicators (Wu et al., 2012).
