Urbanisation in the world
Urbanization process is a domain of developing countries.
One of the results of the extremely high densities of fast-growing populations
is "wild development", leading to such negative social and ecological effects as:
[...]
+ more Combined effects of urbanization, industrialization, and population growth greatly modify
landscapes and thus the continuous circulation of water within catchments and the Earth's
hydrosphere - the hydrological cycle [...]
+ moreAquatic habitats are water bodies supporting aquatic life. Increased temperatures of effluents, greater discharges of water, pollutants and waste, and changes in water bodies morphology impact all the basic habitats characteristics.
[...]
+ more A balanced approach addressing the pressing issues in urban environment is not common in the water service sector
[...] + more From the point of view of environmental science, urban environment can be considered as a highly condensed anthropogenic system, which is organised for efficient flow of water, matter, energy and information

Name of activity: |
Towards sustainable urban groundwater management |
Objective: |
Enhanced understanding of the role and the interactions of groundwater in the urban environment for sustainable integrated strategies |
|
Description: |
Evaluation and further development, including analysis of case studies, of approaches for the assessment of groundwater quantity (spatial and temporal distribution), quality (including pollution and contamination), susceptibility to over-exploitation and control of pollution sources
Specific issues which will be addressed are:
- Changes in water balance due to urbanisation: storm water recharge,
leakage from drain water, sewer and wastewater infiltration and exfiltration
- Groundwater interaction with soil water zone (including urban agriculture and forestry)
- Groundwater/surface water (including marine water) interaction
- Management-of groundwater table dynamics (raising and lowering)
|
|
Implementation strategy: |
- Identification of key issues of urban groundwater
- Designing analytic framework to get the specific models in implementation
- Capacity building/awareness raising
|
|
Implementation mechanism: |
Workshops, development of analytic tools and case studies; regional studies (including cooperation RCUWM-Tehran); training and awareness-raising activities. |
|
Expected results: |
- New modelling, planning and management tools
- Guideline on urban groundwater management including use of analytic tools,
- Training and awareness rising material for urban planners and managers, water managers and public at large on urban groundwater
|
|
Beneficiary groups: |
Urban water research and professional community in the areas facing groundwater problems; public at large. |
|
Expected executing and supporting partners: |
IAH,IOC, IAHR, BAC, JIIHP, IGCP |
|
Duration/schedule: |
-- |
|
Proposed
co-ordinator/focal point: |
D. Pokrajac (co-ordinator), Kinzelbach (member), Ken Howard (IAH – Commission on Groundwater in Urban Areas) |
