Airborne LIDAR Technology for Sustainable Watershed Management: Ecological Health of Riparian Zones

Problem Description / Relevance to Water Security: 

Airborne LIDAR measurements principally lead to the highly accurate 3D reconstruction of the landscape and its features. By mounting LIDAR measurement units on an aircraft large areas can be measured relatively quickly and cost effectively. Airborne LIDAR measurements can then be used to reconstruct a bare earth landscape as well as featured landscape which includes vegetation, buildings and other. These landscape reconstructions can then be used for a number of applications such as archeology, water and coastline management, farming, forestry, geology and conservation.

ICT Application / Outcome: 

Michez et al. (2013) examine the application of LIDAR data to monitor the ecological riparian zones, which are of concern in most parts of Europe due to the European Water Framework Directive. As a transition zone between dry and wet environments riparian areas are typically high in ecosystem productivity and biodiversity. The authors use LIDAR point cloud data to derive a Digital Terrain Model (DTM) and canopy height model which allows for establishing general riparian zone attributes and ecological integrity.

GIS Based Tool for the Landscape Retention Planning

Problem Description / Relevance to Water Security: 

The proposed analysis was relevant to mitigation of droughts and floods. The other aim was to preserve the biodiversity of habitats that are strongly related to water resources, including habitats and species of a great natural value. Measures categorised as small retention aims to cause a slowdown of surface water runoff, rainwater outflow, and subsurface flow. While planning for undertaking such measures, measures aiming at retention of water within the catchment by increasing soil retention, use of aquatic ecosystems, old meanders and ponds should be prioritised.

ICT Application / Outcome: 

The valorisation procedure was done (Figure 1) in following steps:

GIS Based Communication Platform for the Sustainable Management of Transboundary Water Resources in Lithuania, Poland, Belarus and Kaliningrad Region (Russia)

Problem Description / Relevance to Water Security: 

Pregolya and the Neman rivers are heavily affected by anthropogenic pressures in all four countries. The lack of basin wide information on pressures and current ecological and chemical status of water bodies is an important issue for the sustainable management in the region. Due to the political situation in the region the sustainable transboundary management of river basins was limited. So far the planning of water resources was usually based only on national data.

ICT Application / Outcome: 

A GIS database consisting of 12 transboundary GIS layers (Table 1) and more than 100 attribute fields was created. The database content is based on national information. The information for different countries was obtained from various sources: official GIS maps, official statistical data, digitized paper maps, reports, literature, etc. The long list of sources meant that the detail level of the map was diverse. The data harmonization was necessary to provide the unified basin wide information layers.

Remote Sensing Based Agricultural Drought Monitoring and Yield Loss Prediction Method

Problem Description / Relevance to Water Security: 

The World Meteorological Organization (WMO) and Global Water Partnership (GWP) have launched a joint Integrated Drought Management Programme (IDMP) in March 2013, to improve monitoring and prevention of one of the world’s greatest natural hazards. GWP is responding to the climate change challenge through a portfolio of programmes and projects aimed at building climate resilience through better water management (Kindler and Thalmeinerova 2012).

ICT Application / Outcome: 

The case study has three important steps, which correspond and relate to each other in hierarchical way.

Application of Multi-Sensor Remote Sensing for Flood Protection Planning Over the Sajó Valley

Problem Description / Relevance to Water Security: 

The project was set up following the flooding of 2010, when Hungary experienced a record rainfall in May and June and consequently a nation-wide flood came about on smaller and larger rivers. The most affected areas and settlements were in the Sajó valley. An approximately 100 year return period flood wave arrived to the Hungarian border in June 2010 that increased to a once-in-200 year flood on the lower parts of the river.

ICT Application / Outcome: 

The Sajó valley airborne laser scanning and aerial digital imagery have been made on 121 km2 area in Hungary (17th June 2013), and on 190 km2 area in Slovakia (17-18th July 2013).

Airborne Laser Scanning and Aerial Hyperspectral Imaging Technologies in Disaster Management: Hungary, Kolontár Red-Mud Spill

Problem Description / Relevance to Water Security: 

On October 4, 2010 the embankment of the red mud reservoir failed and released a mixture of 600-700 thousand cubic meters of red mud and water. The mud, a byproduct of refining aluminium from bauxite ore, was dangerously alkaline, extremely salty and contained potentially toxic metals like chromium and vanadium. Lower parts of the settlements of Kolontár, Devecser and Somlóvásárhely villages were flooded. Ten people died, and another 120 people were injured. The red mud flooded 800 hectares of surrounding areas.

ICT Application / Outcome: 

Survey and analysis of the effects of red mud disaster-prone area and information service for authorities:

ArcSWAT Application in Basin-Scale Water Security Assessments: Azov Sea Case Study

Problem Description / Relevance to Water Security: 

The current study investigates the change of water supply in the Azov Basin, in particular in the Tsimlyansk reservoir under different land use and climate change scenarios by 2050.

ICT Application / Outcome: 

Spatially-explicit scenarios of climate and land cover changes using datasets of the EnviroGRIDs project were used for assessing water security threats using the SWAT model.

Scenarios were built based on outputs of the Metronamica model, which allows assessing spatial development in the land use depending on external factors and policy measures (RIKS 2005).  The scenarios were based on the storylines proposed by IPCC-SRES (Nakicenovic et al. 2000) corresponding to the different ways of global socio-economic development.
