Water management and policy-making typically require development of
complex models and integrated methods of model analysis.
The staff of the IME Project has a long history of diverse water-related
activities. We summarize here only the two current activities that develop and
apply novel methodology to two water-related extremes: scarcity and
floods. The first deals with supporting water management in the Mexico
City basin.
The second concerns integrated management of catastrophic flood risks.
The aquifer system of the Basin of Mexico is the main source of water supply to the Mexico City Metropolitan Zone (MCMZ) and its nearly 20 million inhabitants. The management of the Basin's water resources requires improved understanding of regional groundwater flow patterns, for which large amounts of data are required. Groundwater management policies can be implemented through an optimization/simulation approach for which a regional groundwater flow model is required. Additionally, the effect that land cover change (e.g. urban growth) has on aquifer recharge needs to be considered, for which a daily soil water balance was developed using the first regional database in the study area.

Integrated modeling for management of catastrophic flood risks
The aim of this project is to conduct conceptual and model-based analysis
of structural and financial measures for reducing regional impacts from extreme
floods.
The projects builds on the integrated catastrophic risks management model developed
at IIASA for a number
of catastrophic risks, e.g., floods, earthquakes, windstorms.
The methodological challenges relate to selection of risk-adjusted criteria for
robust decisions; issues of joint scaling of data, models and decisions; the
GIS-based catastrophe models (generators); simulation of
location-specific risk exposures and losses; fast Adaptive Monte Carlo optimization;
the choice of appropriate discounting rates to justify long-term investments;
evaluation of multipillar risk-management programs for the
analysis of recent catastrophic floods on Tisza river in Hungary and Ukraine.

This is a joint activity of the IME and LUC programs. For more information, please contact Tatiana Ermolieva.
