DSS Architecture for Water Uses Management

AbstractManagement of water uses requests to harmonize demands and needs which are getting more and more complex and sophisticated. During the past 3 decades, modelling systems for hydrology, hydraulics and water quality have been used as stand alone products and were used in order to produce an analysis of a current situation and to generate forecast according to different horizons. The current situation, characterized by the fast increase of monitoring devices mainly in the urban environments, requests an integration of the modelling tools in global information systems that are now dedicated to the global management of urban environments and related services. Energy distribution, water distribution, solid wastes collection, traffic optimization are today major issues for cities that are looking for functional Decisions Supports Systems that may integrated the various components and operate in a sustainable perspective. The modelling systems used for hydrology, hydraulic and water quality have to integrate a common framework allowing modular approach and interoperability. The paper presents a generic operational approach that could be implemented in order to address the management of water uses in a complex urban environment: water supply security issues from groundwater resources, inundation risk and water resources management under the perspective of climate change. The architecture is based on the interoperability of the various models and is integrated in a platform allowing to organize the workflows of data and the production of real time information's used by the decision makers. The current approached is implemented within the AquaVar project on the Var catchment located in the French Riviera

Flood Resilience Index - Methodology And Application

In recent years the number of people affected by flooding processes increases up to the point where the organisational structure of urban communities threatens to experience the significant direct and indirect damages. The vulnerability to flooding processes due to sophisticated assets is high and the assessment of flood resilience becomes the main direction to follow within integrated flood risk management. This paper takes a first step in bringing resilience in integrated flood risk management through a framework that is employing five dimensions in order to evaluate the level of disturbance and ability to preserve and functioning during and after the flooding processes on one side and connected with the flood risk management cycle on the other side. The method recognises different scales and functions within the urban system. The application is done on city of Nice taking into account existing flooding processes, economic, social and institutional characteristics

Assessment Of Climate Change On Flood Dynamic With Deterministic Hydrological Model. Application To The Vugia-Thubon Catchment - Viet Nam

In recent years, Climate Change is commonly known as global warming and associated with sea level rise. Such processes are some one of the most serious challenges facing the human beings in the 21st century. Under the impact of this phenomena, extreme climatic phenomena are supposed to more frequent and serious, leading to natural disasters especially related to water. Flood risk represent a major issue especially for developing countries where the economy as well as the adapted capacity against disaster are still poor. As shown in World Bank studies, with more than 70% of the population works in the agriculture, inhabitants essentially concentrate at the coastal plain, Vietnam is among the countries most heavily affected by the consequences of climate change. To get more understanding the impact of this natural phenomena to Vietnamese people, a methodology has been elaborated in order to asses different climate scenarios over a large catchment and flood dynamic. The simulatiosn are based on a validated deterministic hydrological model which is integrating geology, soil, topography, river systems and climate variables. The validation of the model is obtained through measurements and observationsmade at different stations within the catchement. The actual climate (30 years) is properly reproduced by the model and provide a clear view about the flood processes. Future climate is obtained from downscaled GCM data that provide 30 years of hydrological variables to the 2050 and 2100 horizons. The new simulation allows to analyze the changes in the flood dynamic and to perform the frequency and the return period anlaysis. The approach allows to provide an operational approach for integrating the climate change within the engineering design activitiesdedicated to flood protection measures and resilience strategies
