2. Specific problems that road owner

have to prepare for.

3. Biggest Challenges induced by climate

4. Measures taken

• Create a Method

• Swedish Road Administration

Long Term Plan

1. Introduction

1. Introduction

1. Introduction

• In the Southwest the country consist of silt or clay

• Risk of flooding in the Southwest and Northern

• Vulnerabilities

• Stemming at low bridges and culverts

• Culverts and bridges over small water courses

• Erosion damages on Bridge support

2. Specific problems that road owner have to prepare for.

The effect of a cloudburst in winter could be

more damaging depending on the fact that the

ground is frozen and culverts could be stemmed

by ice and snow.

2. Specific problems that road owner have to prepare for.

The sea level rise is another

problem where the rise is larger

than the elevation of the land. The

exposed objects to this vulnerability

are low-lying road stretches and

tunnels.

2. Specific problems that road owner have to prepare for.

Lead water away from the road

structures.

Ditches and culverts must be given much

higher priority and resources given.

3. Biggest Challenges induced by climate change

• In 2005, the instructions for method ‘Risk analysis chosen

road strech’ was publised

• Primarly handles the analysis of risks of varying character

and concerns road and bridges

• The emphasis has been place on risk of landslide and

collapse, damage on road and bridges with high water

flow or flooding

4. Measures Taken

An example of making road cut slope more stable.

• Allotments have been addressed to measures to prevent

negative effects caused by climate change

• Most is related to preventive measures but also the

following subjets:

� One responsible specialist on the subject

should be appointed in the SRA

� Research and development ought to be

done together with other countries

� When constructing new roads, the effects

of climate change should be a part of the

dimensioning

� Areas with higher risk due to climate

change shoul be specifically noticed at risk

analysis

� Studies of vulnerable areas should be

pointed out
