ICDC 10 ExSat7: Grimsel – Aletsch: Alpine hydrology, water resources and adaptation under climate change Saturday 26 August 2017, 08.30 – 19.30 h. Guides: Prof. Dr. Rolf Weingartner and Dr. Ole Rössler, University of Bern We start this excursion with a tour of the Grimsel and Alesch areas, a high alpine world of glaciers and water and home of the Jungfrau‐Aletsch‐Bietschhorn UNESCO World heritage site. We continue through the Valais, a dry inner alpine valley, and return through the historic Lötschberg tunnel. Topics of the excursion include different aspects of alpine hydrology under climate change, natural and managed discharge, the importance of snow and ice, water reservoirs and hydropower production. Impacts of climate change on the cryosphere and water resources will be discussed, as will possible adaptation strategies. Itinerary We depart from Interlaken in small buses and ride through the beautiful U‐shaped Hasli valley up to Grimsel Pass, over to Obergoms and then to Mörel. In Mörel, we take the cable car to Bettmeralp‐Moosfluh to enjoy a spectacular view of the Great Aletsch Glacier, the largest glacier in the Alps. From Mörel, we continue the bus ride to Brig, Visp and the Lötschen Valley. We return to Interlaken via the Lötschberg tunnel and Spiez. Equipment, food and drinks Bring warm clothes, rain gear, sunglasses and sun protection. Grimsel Pass is at 2180 masl, so it might be fresh and windy outside. Short walks during the bus stops. Lunch: a lunch bag (sandwich, chocolate and fruit, 1 L water) will be provided. Maximum number of Participants 45; minimum 30 Costs The registration fee covers transportation (bus and cable car) and a lunch bag. Price: 100 CHF Disclaimer Health insurance and insurance against accidents is fully within the responsibility of the participants. The program may be subject to small changes. .

Visitor Information Sheet with Map of the Grimsel Test Site
Grimsel Test Site (GTS) Information sheet Visitor season is from the end of May to the middle of October, Monday to Saturday The Grimsel Test Site (GTS) is located at an altitude of 1730 m a.s.l. above Meiringen in Canton Bern. It is constructed in the granite formations of the Aar Massif, some 450 m beneath the Juchlistock mountain. The tunnel system is around 1 kilometre long and offers ideal conditions for performing a range of research projects. Today, more than 20 partner organisations are involved in the work at the GTS. How do I register a visitor group? • Visits are possible only if the date is arranged in advance (see contact address). You will then receive the registration documents by post. The form "Visitor Application" should be sent to Nagra at least 6 weeks before the visit. Around 4 weeks before the date, you will receive written confirmation from us. The visitor list should then be returned to Nagra at least 2 weeks before the visit. Contact address • Nagra ● National Cooperative for the Disposal of Radioactive Waste ● Hardstrasse 73 ● CH-5430 Wettingen ● Tel. +41 56 437 11 11 ● [email protected] ● www.nagra.ch Arrival and departure • Visitors are responsible themselves for organising transport to and from the agreed meeting-point, which is usually Gerstenegg. • Groups of more than 10 persons should attempt, where possible, to arrive by bus (coach).

High Quality Modelling of Hydro Power Plants for Restoration Studies
HIGH QUALITY MODELLING OF HYDRO POWER PLANTS FOR RESTORATION STUDIES H. W. Weber a, M. Hladky a, T. Haase a, S. Spreng b, C. N. Moser c a Institute of Power Electrical Engineering, University of Rostock, Albert-Einstein- Str. 2, 18051 Rostock, Germany b Aare-Tessin AG für Elektrizität ,Bahnhofquai 12, 4601 Olten, Switzerland c Bernische Kraftwerke FMB Energie AG, Victoriaplatz 2, 3000 Bern 25, Switzerland Abstract: The verification of existing plans for network restoration after blackouts in European electrical energy systems becomes more and more important with the ongoing deregulation process. For this verification high quality computer models of the electrical system are necessary which are able to generate exact results for all possible restoration scenarios. The most important elements of these models are the power plants, which have to be developed with high accuracy. Therefore in this contribution the possible quality of power plant modelling will be shown exemplarily for a francis type and a pelton type hydro power plant, both located in the Swiss Alps. Copyright © 2002 IFAC Keywords: power plant modelling, simulation of electrical network restoration 1. INTRODUCTION presented, one a francis type and one a pelton type plant.

Jungfrau Region – Program Inspiration Spring
JUNGFRAU REGION – PROGRAM INSPIRATION SPRING DAY 1 MEIRINGEN Right at the back of the Bernese Oberland, at the foot of lake Brienz and surrounded by countless mountain peaks there's a village called Meiringen. Together with four other communities Meiringen builds the Haslital. Tourists all around the world visits this popular place with about 5000 inhabitants. Meiringen is the perfect point of departure for many adventures around the Haslital. ~2h AARE GORGE The Haslital, one of the large valleys in the central alps, stretches from the Grimsel Pass to the Lake of Brienz. The flat valley floor of the lower Haslital is separated from the upper valley by a transverse rock formation. Over thousands of years, the Aare River eroded a path through this rock formation resulting in a gorge which is 1’400 metres long and up to 200 metres deep. This gorge has been accessible for over 100 years by a system of safe paths and tunnels. The walk through the gorge is a very special way to experience nature ~3h ALPEN TOWER In summer the Alpen tower is a perfect point of departure for many hikes and for paragliding. And don't miss the display of Muggestutz' winter world at the Alpen tower. 1 MERINGUES TASTING In the Museum of culinary art in Frankfurt the source of the development of the «Meringue» was discovered before the Second World War from these papers (unfortunately destroyed during the war) it becomes clear that the «Meringue» was first made by a patissier called Casparini around 1600 in Meiringen. He named his creation after the place where the idea was born and that was Meiringen.

Melting Glaciers Key to Greater Reliance on Hydroelectric Power? 14 September 2012, by Sandy Evangelista
Melting glaciers key to greater reliance on hydroelectric power? 14 September 2012, by Sandy Evangelista Credit: 2012 EPFL (Phys.org)—The great glaciers of the Alps are melting. Several climate change scenarios, some of which are based on an average temperature increase of +4°C, predict their complete disappearance by the end of this century. As they retreat, the glaciers uncover cavities; these fill with meltwater, becoming lakes. The Swiss National Science Foundation (SNSF) is funding a research project on the risks and possibilities of these new mountain lakes. Anton Schleiss, director of EPFL's Hydraulic Constructions Laboratory, is participating in the project. "Glaciers store water and transfer winter precipitation into summer runoff. Once they have disappeared, we will need to manage these new reservoirs, which will take over this water storage In the first scenario, the lake water would go role." through turbines on site, as part of the construction of a future Gletsch-Oberwald hydroelectric power For his Master's thesis project, EPFL Civil plant.

The second scenario would use the existing hydroelectric structures in place in Oberhasli, on the other side of the Grimsel Pass, at the drainage 1 / 2 divide between the Rhine and Rhone watersheds. Because the water can pass through existing turbines several times on its journey downstream, this solution is much cheaper and could generate more electricity.
