III - URBAN OPPORTUNITIES
A Blue green network
1 understanding the current network, in particular the stream valleys and dry valleys;
here peak storage of water
2 entire stream valleys shall be transformed into parks with peak storage in ponds
3 green areas allow water to flow along a hydraulic gradient towards the stream

differentiation: dry (infiltration) and wet (storage)
fluctuation: heavy duty facilities and double (multiple) use of space
discharging water from neighborhoods via visible gutters towards the stream

City centre: see guidingmodel of the City
water and shade in downtown areas to minimize the effects of heat stress
stream valleys also function as a wind corridor
extra water storage at the lower end of streams and hollow roads

energy yield from running water and from sewage
utilizing areas with historical water-related activities for water and green
linking the removal of contaminants to heat cold storage and geothermal energy
II - REGIONAL OPPORTUNITIES
A Blue green network
1 understanding the current network of stream valleys, forested hills and terrace edges
2 connecting to an international wetland corridor, existing nature reserves and
seepage areas
3 extra water storage in low spots of stream valleys
4 encroachment of tall herbs and scrub, partly water storage

promote soil vitality and link it to a differentiation in land use
erosion control by planting terrace edges, also infiltration
properly maintained hillside forests on terrace edges
disclose special points such as quarries and sinkholes (dolines)
