Abstract:
Most of the economic production for the majority of countries is concentrated in the urban areas. The future development is bound to the capacity of the urban area to adapt to climate change and social and economic pressures and urban climatic resilience represents a critical aspect. There is no magical recipe addressing the urban subsurface management and planning, all the involved actors, specialists, and researchers are in many cases limited by their own experience and know-how and tend to exaggerate and to point out certain aspects (geothermal potential, groundwater infrastructure interaction, water and ground pollution, geotechnical zoning, etc) and this represents the major limitation and drawback. The main objective is represented by the development of a new holistic method to map the underground Space for a future Urban climatic Resilience. Reaching this objective is translated by the Urban Subsurface Atlas. The Urban Subsurface Atlas it is a new and innovative concept. The innovative aspect of this new atlas comes from the fact that will create a better understanding of the engineering and planning issues under the city. It will be a bridge between the policymakers and the specialists, as it will use the power tools of mapping and 3D visualization. Horus project aims to have an impact upon the scientific community, the technical and specialist community and the involved stakeholders and the general public. For the validation of the new mapping method, 3 city case studies were chosen: Bucuresti, Brasov, and Rm. Valcea. The general workflow of the project follows a step by step procedure, from the conceptual data framework of the urban underground space to data acquisition of supplementary data, to methodology development and case study examples with direct calibration and validation. During the project lifetime, management and dissemination activities are continuous.

Abstract:
By 2050 it is estimated that two-thirds of the world's population will live in urban areas. Europe's population is already substantially urbanised and as populations grow, sustainable development - a pattern of growth in which resource use aims to meet human needs while preserving the environment for present and future generations - is increasingly threatened.
In contrast to the attention given to the visible (above ground) expressions of cities, there is a marked lack of appreciation of the importance of the subsurface amongst those who plan, develop and manage cities. For underground space to remain a societal asset, we need to plan and manage its use. In cities such as Helsinki and St Petersburg subsurface urban development has been integrated into the land-use planning system. If this is not done, the greatest benefits of underground space will prove to be short-lived. For example, unanticipated disruption of groundwater flows can cause wells to dry up, cause ingress of pollutants, damage to sites of historical interest or cause flooding of existing subsurface developments.
In 2012, the British Geological Survey together with other geological surveys in northern Europe, put forward a proposal to the Transport and Urban theme of COST for greater interaction and networking between experts who develop urban subsurface knowledge and those who can benefit most from it - urban decision-makers, planners and practitioners (private consultants and contractors).

Abstract:
Maps of vulnerability to pollution represent powerful instruments given the possibility to take preventive or corrective measures with respect to land use to protect groundwater. Even if in the last 15 years an effort in groundwater vulnerability assessment has been seen, it is necessary to advance the combination of intrinsic vulnerability mapping with modeling approach.
The application of a dynamic concept of vulnerability intrinsic to groundwater modeling requires a new methodology. The current project proposes the development of a new method for intrinsic vulnerability of groundwater resources assessment considering the properties controlling the contaminant transfer from the land surface to the groundwater surface. The method will be consistent with physics of flow and contaminant transport by allowing the estimation of contaminant transfer time, duration, and concentration level of the contamination at groundwater surface.
In order to test and validate the developed method, two test sites will be used, one in Romania and the second in Spain, following an already existing framework protocol concerning scientific collaboration in the research area of protecting groundwater used as water supply.
The research effort will offer a reliable instrument in the hands of water authorities facilitating the implementation of the EU water relevant directives. The team will comply with water legislation and provide knowledge and methodology for a strategy of implementing the WFD.

Abstract:
We propose a project to improve the monitoring and impact assessment of snow in Romania under present climate and future scenarios. The current status is that the network of weather stations is too sparse in regions with seasonal snow cover to provide reliable snow monitoring and impact applications. To mitigate this, we will develop new methods for monitoring and impact assessment of snow that will use the upcoming Sentinel-1 and Sentinel-3 satellites in combination with existing weather stations and snow pack modelling from weather to climate timescales.
Low spatial and temporal resolution of available in-situ snow data prevents a more accurate and timely monitoring of seasonal snow and related impact and adaptation applications. Snow monitoring is essential for prediction of flooding due to rapid snow melt, to provide snow avalanche risk forecasts, and for water resource management, including hydropower production, agriculture, groundwater and drinking water.
One solution could be to increase the number of in-situ observations, by adding more permanent measuring points to the existing network of manual and automatic weather stations. However, this would result in a substantial investment in new equipment, and increased operational and maintenance costs. In addition, even with a much denser network of weather stations, there will still be local variations in snow depth, temperature, etc., in areas not covered by the weather stations that will not be captured, not even with modern modelling techniques. This calls for the use of satellite data.
For climate change implications, a new generation of climate models (from Coupled Model Intercomparison Project 5 CMIP5) and new climate scenarios for future (Representative Concentration Pathways - RCPs) make necessary updating and extending the knowledge on local and regional snow-related hazards and resources for impact and adaptation applications.
We propose a more cost-effective approach, by including daily satellite observations from the upcoming Sentinel-1 and Sentinel-3. The Norwegian project partner, Norsk Regnesentral (Norwegian Computing Center), has already developed methods for an operational snow monitoring service in Norway, providing daily, 1 km resolution maps of snow parameters from the sensor Terra/MODIS sensor, optionally combined with the data from the radar satellite Radarsat-2. By adjusting the methods to Sentinel data, and calibrating and validating it on Romanian ground observations, we will integrate the snow parameter maps from satellite observations with weather station data and snow pack modelling in an advanced snow monitoring algorithm.
The project will deliver a prototype snow monitoring system that combines daily satellite data from Sentinel-1 and Sentinel-3 with in-situ weather station observations and state-of-the-art snowpack and climate modelling. Three important applications of snow monitoring will be demonstrated: hydrological modelling, snow-melt induced flash flood warning and snow avalanche warning. The project will also assess the impact of snow under present and future climate conditions on: flash flood statistics due to snow melt contributions, avalanche statistics and groundwater.
We expect that the project will produce the following results:
• A prototype near-real-time snow monitoring system, combining automatic processing of Sentinel-1/-3 data, in-situ weather station data and snowpack modelling.
• A convincing demonstration of the value of Sentinel-based snow data in snow avalanche and snowmelt forecast and in water resources management.
• The necessary expertise for successfully approaching implementations in the GEOSS Societal Benefit Areas, thus paving the way for a large-scale utilisation of satellite derived snow products in Romania.
• Updating and extending the climate knowledge on local and regional snow-related hazards and resources in Romania.
• A number of peer-reviewed journal publications and conference presentations.
