Q

What is social hydrology

A
  • a new science that is aimed at understanding the dynamics and co-evolution of coupled human-water systems
  • Understanding, interpretation and scenario development of the flows and stocks in the human‐modified water cycle at multiple scales including two‐way feedbacks between human and water systems
  • Understanding the dynamic cross-scale interactions and feedbacks between the natural and human processes that may give rise to the water sustainability challenges that we face in the Anthropocene

Q

What are the ecological functions of floods

A

20

23
Q

  • combined sequences of different sizes and types
24
Q

What is the role of hydropower in development strategies

A
  • Energy Production
  • Reducing Maximum flows (Flood control)
  • Ensuring Minimum flows (irrigation & drought control)
  • Political influence
25
Q

What is the role of hydropower in ENERGY development strategy?

A
  • Driven by increasing energy demands (pop. increase & energy intense economic growth & lifestyle)
  • Large additional potential
  • Low carbon emission energy
  • Large storage capacity/flexibility (compliment intermittent renewable sources like solar & wind)
  • Grid stability (load can vary based on grid requirements)
  • Low O&M costs
  • high energy payback ratio (high funding req. tho)
26
Q

What is the role of hydropower in FLOW CONTROL development strategy?

A
  • Flood control
  • irrigation
  • Drought control & env. flows
  • potential to managed incr. variability due to CC
27
Q

What is the role of hydropower in POLITICAL INFLUENCE development strategy?

A
  • Infrastructure investment as driver of economic growth
  • Flow control between countries
  • Visibility & public support for political leadership
  • National pride (Energy self-sufficiency & Technological development)
28
Q

What are some env. impacts of hydropower reservoir?

A
  • reservoir inundation (deforestation & forced relocation)
  • Reservoir sedimentation (reduced velocity, reduced sedimentation downstream causes erosion)
  • GHG emissions from biomass in inundated area (decomp at bottom of reservoirs)
  • Evaporation
  • Water Quality (low DO, impact ecosystem)
29
Q

What are some downstream impact of hydropower

A
  • In theory ->more flexibility in flow control (tied to competing economic interests & adverse downstream ecological impacts due to altered flow
  • Environmental flows -> Ensuring downstream water functions, but Restrictions on reservoir levels reduces benefits of hydropower’s grid regulating capacity
  • Flood protection (Conflicts with sustaining high reservoir level for energy production & Dam emergency release can cause flash floods)
  • Aquatic habitats (fish passages)
30
Q

Reuse of water acceptance 10 factors

A

1) degree of human contact is minimal;
2) protection of public health is clear;
3) protection of the environment is a clear benefit of the reuse;
4) promotion of water conservation is a clear benefit of the reuse;
5) cost of treatment and distribution technologies and systems is reasonable;
6) perception of wastewater as the source of reclaimed water is minimal;
7) awareness of water supply problems in the community is high;
8) the role of reclaimed water in overall water supply scheme is clear;
9) perception of the quality of reclaimed water is high; and
10) confidence in local management of public utilities and technologies is high.

31

-Imagery
(slide 16)

32
Q

what 4 principals came out of the 1992 Dublin Conference

A
  1. Freshwater is a finite and vulnerable resource, essential to sustain life, development and the environment
  2. Water development and management should be based on a participatory approach, involving users, planners and policy makers at all levels
  3. Women play a central part in the provision, management and safeguarding of water.
  4. Water has an economic value in all its competing uses and should be recognized as an economic good….
