Ex-5: Japan Society of Engineering Geology (JSEG) Special Excursion

Post-conference excursions

Ex-5: Japan Society of Engineering Geology (JSEG) Special Excursion (three days) - Gorkha and Pokhara Area including Kathmandu-Pokhara roadside slope mitigation 

Japan Society of Engineering Geology (JSEG) is organizing a special excursion and it is excursion five (Ex-5).  This excursion is planned as per the special arrangement of JSEG and the organizing committee of ARC-11 is very happy to support JSEG to manage the excursion.

This excursion will be operated both English and Japanese and all participants are welcomed to participate. This excursion includes merged few programs of Ex-3 and Ex-4.

Tentative Schedule of Ex-5 for ARC-11

Purpose of excursion

1) To observe geomorphologicai and engineering geological characteristics of the Midland in the Himalayan Range.

2) To observe the damages in the Midland due to the 2015 Gorkha Earthquake and to consider reasons of very few occurrence of earthquake-triggered landslides in the Midland.

3) To consider the effect of the 2015 Gorkha Earthquake to building on the Kathmandu valley.

4) To observe geomorphologicai and engineering geological characteristics of the Pokhara Valley in front of the Annapurna Range.

5) To observe the geo-disasters in the Pokhara Valley and to consider relation between geo-disasters and beautiful landscapes

 6) To consider the origin of Midland and effect on not only land use and disasters, but also an evolution of the Himalayas.

7) To consider the sustainable development of Nepal based on the concept of geo-park.
