5th Annual INARCH Workshop

The 5th Annual INARCH Workshop, originally planned for March 31 – April 1, 2020, has been cancelled due to COVID-19. We will look to hold another in-person meeting when the circumstances allow. In the interim, we are exploring options for a virtual gathering.

HBV.IANIGLA: Decoupled Hydrological Model for Research and Education Purposes

The HBV (Hydrologiska Byråns Vattenbalansavdelning) hydrological model is decoupled to allow the user to build his/her own model. This version was developed by the author in IANIGLA-CONICET (Instituto Argentino de Nivologia, Glaciologia y Ciencias Ambientales – Consejo Nacional de Investigaciones Cientificas y Tecnicas) for hydroclimatic studies in the Andes. HBV.IANIGLA incorporates modules for precipitation and temperature interpolation, and also for clean and debris covered ice melt estimations.

You can access the HBV.IANIGLA and its documentation here.

INARCH Statement for October 2018

Following the 4th annual INARCH workshop in Chile (24th – 26th October 2018), the following statement was issued:

  • INARCH has identified the importance of the changing High Mountain Water Cycle to global initiatives such as GEWEX, ANDEX, GWF, TPE and is contributing to a WMO High Mountain Summit and initiative. INARCH supports the idea of an International Year of Snow and Ice and also a year devoted to Mountain Prediction.
  • INARCH has published invaluable mountain catchment hydrometeorological datasets from around the world through a special issue of Earth System Science Data with 19 articles. It has expanded to 28 catchments with contributions from 45 scientists based around the world.
  • INARCH has identified dramatic snowpack decline and glacial retreat in the Andes and Patagonia as issues of global concern with some of the highest rates of glacial ablation in the world, due to both sublimation and melt. Global warming has included mountain mega-droughts in South America, causing hydrological shortages downstream. Complications in glacial modelling due to high sublimation rates, debris cover and the occurrence of penitent surfaces require physically based energy balance techniques for glacier hydrology in the Andes. Mining impacts on some of these glaciers are further accelerating ablation through direct disturbance and dust. An increasing number of glaciers are now debris-covered and so techniques to calculate icemelt under debris are needed in hydrological models. International and national mountain hydrology research programmes should prioritize research in the Andes to address these problems.
  • The advent of large-area, high-resolution atmospheric models at 4 km or less, now permits more confident meteorological drivers for advanced snow and glacier hydrology models in complex mountain terrain. The performance of these high resolution atmospheric models needs to be assessed at point and areal scales and spatial datasets for such assessments and for bias-correction need to be assembled. Global application of these products to mountains is needed. High resolution snow and ice hydrology models, including hillslope hydrology processes need development to take advantage of the more accurate alpine precipitation products that will result.
  • There is tremendous potential to assimilate high resolution remote sensing products such as snow depth from airborne LiDAR, albedo, grain size and impurities from hyperspectral sensors and visible snowcovered area from multiple platforms into advanced snow hydrology prediction models and some examples of this are occurring. Efforts are needed to demonstrate how more mountain ranges around the world can be measured by these products and how the outputs can be used together to improve snow prediction models.
  • INARCH has quantified the sensitivity of mountain snow hydrology regimes around the world using cold regions hydrological models of virtual alpine basins, driven by reanalysis data, and has shown that decoupling of the snow and hydrological regime with warming is most severe for temperate winter climates with winter precipitation maxima as typified by Mediterranean alpine environments. The results show the controls of both temperature and vapour pressure in determining the sensitivity of mountain snow hydrology to warming. This approach should be extended to examine the sensitivity of mountain glacier hydrology to global warming.
  • INARCH continues to examine the performance of alpine snow models in simple alpine environments by comparison of model outputs to diagnostic measurements in INARCH catchments. The next step should be to examine model performance in extreme alpine environments that are more typical of alpine landscapes.

Details of 3rd annual meeting available online

Summary details of the 3rd Annual INARCH workshop, held on the 8th and 9th February 2018 at the Schneefernerhaus, on the upper slopes of the Zugspitze on the Bavaria / Austria border near Garmisch-Partenkirchen, Germany, are available here. We hope to publish presentations shortly.

We are tentatively planning for the 4th annual meeting to be held on or about 20th – 21st October 2018 in Chile, ahead of the Joint GHP/ANDEX meeting in Santiago (22nd – 26th  October).

8th GEWEX Science Conference in Canmore

Submissions for oral and poster presentations are invited for the 8th GEWEX Science Conference, titled Extremes and Water on the Edge, which will take place from 6th to 11th May 2018 in Canmore, Alberta, Canada. Abstracts are due by 18th December 2017.

The 2018 GEWEX Science Conference will be structured around the topic of challenges confronting our ability to understand and predict changes in climate extremes and the availability of freshwater under the complex factors of natural variability, forced climate change due to human activities, and human management practices.

The conference will reflect research activities that advance the main themes of the GEWEX project and of the two WCRP Grand Challenges on Weather and Climate Extremes and Water for the Food Baskets of the World.


  • Nexus of water, energy, and food
  • Climate extremes
  • Extreme weather
  • Atmospheric modeling and observations
  • Land modeling and observations
  • Mountain and high latitude hydrology
  • Global energy and water cycles

Abstracts for sessions falling under the seven conference themes are welcome. Sessions are listed here. Poster submissions are encouraged.

From 3-5 May 2018, the Young Earth System Scientists (YESS) and Young Hydrological Society (YHS) will hold a Joint YESS-YHS Early Career Researcher (ECR) workshop, Towards Regional Information to Improve our Understanding on Weather and Climate Extreme Events. Information about the workshop and how to apply is available here.

Full week registration: 500 CAD
Full week early bird registration: 450 CAD
Full week for students: 400 CAD
Abstract submission fee (non-refundable): 80 CAD

The conference will be held at the Coast Canmore Hotel and Conference Centre, located in the resort town of Canmore in Alberta, Canada, in the Canadian Rockies.

18 December 2017: Abstracts due
15 January 2018: Abstract acceptance notification
22 January 2018: Travel support notification
