2015-17 Project COST Connectivity ES1306 2015-17

Impact of landscape disturbance on stream and basin connectivity
COST Action ES1306, Czech Ministry of Youth and Education LD 15130
1. Project aims
To assess the influence of landscape disturbance, mainly the changes in land use and land cover structure, forest disturbance, stream modifications on runoff response, flow dynamics, dynamics of fluvial processes and morphological changes in catchments, floodplains and streams. 

The research is be focused on two types of environment sensible to the disturbance or long-term changes in basin and stream connectivity: .(i) the headwater areas of streams in montane regions and .(ii) the catchments in rural areas. 

In headwater regions in montane regions the research will be focused on the changes in the dynamics of runoff response and fluvial processes in catchments and streams. 

In rural catchments, the research will be focused to the changes in the dynamics of erosion-sedimentation processes in river basins, to development of a floodplain and to lake basin siltation. 

2. Research questions

The research in headwater regions will provide answers to the following research questions:
i) What are the key forces that affect the changes of catchment and stream connectivity in montane regions?
ii) How significant is the role of landscape and stream disturbance to the changes in dynamics of runoff response and fluvial processes and to the changes in their retention potential?
iii) What is the contribution of new monitoring, detection and survey techniques to the shift of knowledge on hydrological and fluvial processes
iv) How much the information regarding the processes detected during the detailed monitoring of relatively homogenous experimental catchments can be applied to larger complex basins?

The research in rural catchments will provide answers to the following research questions:
v) How are the changes in the landscape reflected in the observable characteristics of the fluvial and lake systems?
vi) What are the key forces that drive changes to soil erosion, fluvial and lake systems? 
vii) How to define present and future states of fluvial and lake systems considering own monitoring of processes and obtained knowledge?       

3. Research methods
There are applied, tested and developed following techniques for data monitoring and acquisition:
- Automated sensor networks for monitoring of rainall-runoff processes, 
- UAS photogrammetry for acquiring of accurate DEMs and for analysis of spatiotemporal changes of fluvial morphology of streams, 
- Terrestrial LiDAR scanning for analysis of spatial and volumetric changes of riverbeds and floodplains 
- Optical granulometry for qualitative analysis of fluvial deposits
- Automated sampling of suspended solid and water quality parameters, 
- Application of hydrological, hydrodynamic and geostatistical models for the detection, analysis, and simulation of processes.
