NAME

The r.green.hydro - Toolset for computing the hydropower potential.

The r.green.hydro suite computes the hydropower potential.
It is composed of several programs considering different limits (e.g. theoretical, recommended, legal, technical, ecological and economic constraints).
The r.green.hydro suite consists of the following six different parts:

- r.green.hydro.theoretical
calculates for each basin the theoretical maximum hydropower energy potential
input raster maps: - discharge along river network - elevation of the considered region
input vector map:    existing plant position
output vector maps: - available river segments         - optimal plant position

- r.green.hydro.recommended
detects the potential plant position considering legal and ecological constraints and the user's recommendations
input raster maps: - discharge along river network - elevation of the considered region - minimum flow discharge
input vector maps:    - existing plant position    - areas excluded from calculation
output vector maps: - available river segments         - optimal plant position

- r.green.hydro.technical
calculates the hydropower potential considering technical constrains (head losses, efficiency of turbine)
input vector map:    intakes and restitutions of the potential plants
output vector map: - structure (derivation channel and penstock) on both sides of the river for each potential plant

- r.green.hydro.financial
computes the economic costs and values of the plants
input raster maps: - landuse - slope
input vector maps:   - segments of the potential plants   - plant structure     - electric grid
output vector map:    structure of the potential plants with a re-organized table with e.g. power, gross head, total cost

- r.green.hydro.structure
computes the derivation channel and the penstock for each potential plant on both sides of the river
input raster map: elevation of the considered region
input vector map:    segments of the potential plants
output vector map:    structure for each plant on both sides of the river

- r.green.hydro.optimal
detects the position of the potential hydropower plants that can produce the highest possible power
input raster maps: - discharge along river network - elevation of the considered region
input vector map:    considered rivers
output vector maps: - potential river segments         - intake and restitution of each potential plant
