- Phytotechnology and Ecohydrology -
C. Questions veryfying the
utility of ecohydrological and phytotechnological approaches in projects
- Does the project cover the
effect of hydrological processes on the structure and dynamics of the biota
(e.g., the effect of flood peaks on the inhibition of toxic algal blooms, the
effect of reservoir water level on fish reproduction and zooplankton dynamics,
algal density, and water quality, etc.)?

- Does project
cover the effect of biotic structure and temporal variability at catchment
and/or aquatic ecosystem scales on water resource quality, quantity, and
dynamics (e.g., the effect of forest cover and ecotones on the timing and
hydropeaking of flood flows)?
- Do the above
relationships indicate a potential for the improvement of water quality and
hydrological security at the basin scale (i.e., does the project conform to the
first principle of ecohydrology)?
- Does the
understanding these ecohydrological relationships improve the absorption
capacity of the river basin against of human impacts (i.e., does the project
conform to the second principle of ecohydrology)?
- Does the
understanding of these ecohydrological relationships provide a basis for their
application to the sustainable use of the water resources of the basin (e.g.,
does the project conform to the principles of ecological engineering and the
third principle ecohydrology, including its socio-economic aspect)?
- Does the
implementation of the project enhance biodiversity at basin scale?
- Does the
implementation of the proposed project reduce the costs of improving water
resource quality at the basin scale (i.e., low cost vs. high technology)?
- Does the implementation of
the project stimulate (sustainable) economic growth in the basin?
