Addressing Key Questions
• Are potential increases in groundwater recharge from
changing rainfall distributions offset by increased ET?
• Can we define sustainable groundwater abstraction under
non-stationary hydrological conditions?
• What are the key constraints to the representation of
groundwater flow and storage in climate models?
• What aspects of groundwater flow and storage are most
important to hydrological simulations and where?
• On the basis of currently available information, what
methodologies can be used to improve the next generation
of climate models?

Sedimentation problems are matter of global
concern
• the annual erosion of surface soil from
global river basins amounts to 60
billion tons
• 5 to 7 million ha of farmland are
annually ruined
• about 1% of the precious storage
capacity of the world's reservoirs is
annually lost to deposition
• Economic Loss over USD 6
billion/year
International Sediment
Initiative (ISI)
Objectives:


promote the elaboration and monitoring of sediment data
develop appropriate methods and procedures in sediment
management
Recent Activities:




Global evaluation of sediment transport
Case studies for river basins, review of erosion and
sediment related research
Global erosion and sediment information system
(UNESCO IRTCES center, Peking)
Networking, education and training
Are the sediment loads of the world’s rivers
currently changing in response to these
components of global change?
