water Flashcards
what are the role of players in managing land use
-planners have become important in managing the impacts of urbanisation on flood risk because:
-many towns and citys are naturally prone to flooding because of their locations
-many people live in urban places and need protection
-large sums of money are invested in urban property
flood risk management involves actions such as:
-strengthening embankments of streams and rivers
-putting in place flood emergency procedures
-steering urban development away from high risk areas such as flood plains
what are the futures and uncertainties for future drought and flood risk
-the impact of oscillations (e.g. ENSO) is leading to increasingly unreliable patterns of rainfall.
-more frequent cyclone and monsoon events threaten water supplies intermittently
-loss of snow and glaciers threaten many communities in mountainous areas (Himalayas)
-uncertainty arises because modern scientific research is unable to make confident forecasts about the future availability of water. In the future there may also be advances in water technology and factors related to the demand side such as population growth and global developement
