Introduction

• Occasion of the 100th Anniversary of the Croatian G l i l S (H t ki l ški i štit t)Geological Survey (Hrvatski geološki inštitut)

• Congratulations!!!• An opportunity to revise the past cooperation

between neighbouring countries in one field of geology – nowadays societal very visible –

h dgeohazards



Geology and human boundaries

• Humans tend to do strange things…• Defining state boundaries and country borders

regardless of natural conditions• Geology and geological processes disregard

such “artificially made boundaries”• This is not only the opinion of geologists…

Geology and human boundaries – cont.

“Geological sciences and geological structures do not end at national boundaries. Working on the same planet, geologists need

to communicate and share knowledge with each other, and to d h th ’ i ”draw on each other’s experiences.”

Quote from speech by Chinese Premier Wen Jiabao 19 June 2007



OneGeology• A project to make web-accessible the best available

geological map data worldwide at a scale of about 1:1geological map data worldwide at a scale of about 1:1 million, as a Geological Survey contribution to the International Year of Planet Earth (and beyond!!!)

• Make accessible the best geological map data they have available = putting the jigsaw-puzzle together

• Work towards consistent standards for data and access -a consistent data architecture - schematic interoperability

“l li ” dj f d i ll h= “leveling” or adjustment of data, especially at the border areas (long way to go, but specific cases can help to ease the thorny path)

• enhance and increase use and usability of our data = effectivelly solving cross-border problems (usually GH)

Geohazards – GH

• Geohazard = Geologic hazard• Geohazard = A geologic condition (natural or

man-made) that could lead to damage or uncontrolled risk and hence poses a potential danger to life and property

• Geodynamic hazards, general geological h d h d l i l h d i ihazards, hydrogeological hazards, mining related hazards (by EGS definition – 20 types of GH)



The role of GSOs in the GH management cycle

Conceptual model of transboundary aquifer systems(Croatia-Slovenia)

The actual common delineation of transboundary aquifers(Croatia-Slovenia)



Slovenian-Croatian cross-border cooperation in the field of GH (1) – groundwater management• Future conservation and exploitation of these

if i t l h ti itiaquifers require mutual research activities. • Standardized hydrogeological map produced• Tansboundary water divides and aquifer system

delineated. • Water balance was assessed • Water protection areas are extending across

border and are delinated by different criteria which are not directly comparable.

Slovenian-Croatian cross-border cooperation in the field of GH (2) – alluvial sediment pollution• Heavy metals in alluvial sediments of the Drava

RiRiver• Assessment of geochemical background before

industrial revolution; • Evaluation of anthropogenic influence on

sediment and soil pollution in the Drava valley, • Determination of the spatial distribution of heavy

metals in soils on alluvial deposits of the Drava River in Slovenia and Croatia

Slovenian-Croatian cross-border cooperation in the field of GH (2) – alluvial sediment pollution• 134 sampling location • Samples: topsoil (0 5 cm) and subsoil (20 30 cm) + 30• Samples: topsoil (0-5 cm) and subsoil (20-30 cm) + 30

river sediment samples• Analysis for 41 chemical elements was performed• Statistical analysis (basic statictic parameters, R mode

factor analysis)• Geochemical maps – Universal kriging with linear

variogram interpolation methodvariogram interpolation method• Three geogenic and one anthropogenic geochemical

associations were established on the basis of visually indicated similarity of distribution of elemental patterns along the Drava River



Slovenian-Croatian cross-border cooperation in the field of GH (2) – alluvial sediment pollution• A part of the studied area (about 130 km2) is

iti ll ll t d di t th th h ld tcritically polluted according to the thresholds set by legislation.

Conclusions

• Two types of geohazards have been already t kl d b j i d t f Sl i dtackled by joined teams of Slovenian and Coratian geologists – groundwater aquifer management and soil pollution

• Topics to be addressed in the future– Other types of geohazards

Ti ht b d ti– Tighter cross-border cooperation– Capacity & networking–> “Joining forces”– Knowledge transfer –> cost reduction by “Avoiding

duplication”

Conclusions – cont.• And the role of OneGeology? • On-line data accessibility – access to data

not only to geologists, but also decission makers

• Data standardisation before inclusion into 1G data portal = interoperable data1G data portal = interoperable data formats
