Seminar by Dr. Siqiong Luo

Dr. Siqiong Luo, GWF visiting researcher from the Northwest Institute of Eco-Environment and Resources, CAS, China, will present a seminar on Simulation of soil temperature and moisture conditions on the Tibetan Plateau. 

The Tibetan Plateau is a particularly sensitive region to the globe warming. The soil temperature and moisture conditions and their changes on the Tibetan Plateau will have profound effects on surface energy and water exchanges and leading to further climate change. The aim of this presentation is to discuss the soil temperature and moisture conditions which was simulated by land surface model on the Tibetan Plateau from 1961–2010.

The seminar will take place at 12 pm (CST) on May 30, 2018 in NHRC 1261 (seminar room). This event will also be available via WebEx. Details are as follows: │Attend a Meeting │ 928 292 276

Seminar by Dr. Patrick Lloyd-Smith

Please join us for a seminar with Dr. Patrick Lloyd-Smith, Assistant Professor in Agricultural and Resource Economics, University of Saskatchewan. The presentation will be on Assessing Ecological Infrastructure Investments in the Panama Canal Watershed. 

Ecosystems are infrastructure that provide beneficial services to people. Changing ecosystems to enhance services are investments that carry a cost. For ecological infrastructure to play a serious role in society’s infrastructure portfolio, ecological infrastructure investment projects must be assessed beforehand and compared to alternative gray infrastructure investments. We illustrate ecological infrastructure is neither a panacea nor pipe dream by merging natural and social science in an application to the Panama Canal Watershed. Ecological infrastructure can play a targeted role in the Panama Canal Watershed, but is unlikely to be price competitive at the scale required to manage water for the canal. Physical and social constraints limit the ability to acquire ecological infrastructure, which is a barrier to scaling up ecological infrastructure.

The seminar takes place on May 22 at 12 pm CST in 1261 NHRC (seminar room).

CALL FOR ABSTRACTS – GEWEX Session on Hydrology of High-Elevation Areas

CALL FOR ABSTRACTS – Hydrology of High Elevation Areas Session at 7th International GEWEX Conference

Trending Now: Water
7th International Scientific Conference on the Global Energy and Water Cycle
The Hague, The Netherlands, 14-17 July 2014

Abstract Deadline: 14 February 2014

The increasing demand for fresh water and the impacts of climate change on water availability and extreme events highlight why water is a current major global concern and is “Trending Now.” The Conference will celebrate 25 years of GEWEX research and set the stage for the next phase of research addressing the World Climate Research Programme Grand Challenges on water resources, extremes, and climate sensitivity through observations and data sets, their analyses, process studies, model development and exploitation, applications, technology transfer to operational results, and research capacity development and training for the next generation of scientists.

The Conference will include lead speakers in plenary sessions to provide synthesis and perspective, and an extensive set of parallel sessions to support detailed development of specialist themes. Papers are welcome for all parallel sessions, to be given either as oral presentations or posters.

Abstracts are invited for all topics, including: (1) the climate system; (2) land; and (3) atmosphere. For topic details, see

Please consider submitting an abstract to the Hydrology of High Elevation Areas Session:
High mountains often receive relatively high precipitation volumes, which can quickly form runoff from rainfall, or are stored as snow and ice and form melt water when energy inputs are sufficient. This session will focus on advances in high mountain hydrology, including precipitation, process understanding, observational advances, model development and validation, applications, climate change impacts and projections of future snow and ice hydrology under a changing climate.
Conveners: John Pomeroy, Richard Essery, Ma Yaoming

Abstract Submission and Registration
The abstract deadline is 14 February 2014. Links to abstract submission and conference registration are available at: Abstracts will be used to select presentations for poster and oral sessions.

Dr Keith Musselman, Postdoctoral Research Associate at the Centre for Hydrology, will present a seminar entitled
Inter-annual snow accumulation and melt patterns in forested and alpine terrain;
a case study from the Sierra Nevada, California

On Wednesday October 3rd, 2012, at 11:30am, in AGRI 1E85
Results are presented from a study of snowpack dynamics in the southern Sierra Nevada, California. The study area covers 1800 km2 and a 3600 m elevation gradient. The accuracy of a distributed snow model is evaluated against a multi-scale suite of field measurements including a network of snow depth sensors, basin-scale manual surveys, and airborne LiDAR. In general, the model accurately simulated the seasonal maximum snow depth and SWE at lower and middle elevations. The model overestimated SWE at upper elevations where wind effects are pronounced and no precipitation measurements were available. The SWE errors were partially explained (R2 > 0.80, p<0.01) by the distance of the SWE measurement from the nearest precipitation gauge. The results suggest that precipitation uncertainty and wind redistribution are both critical limitations on snow model accuracy, particularly at upper elevations. Analyses of snowmelt patterns highlight distinct differences in melt dynamics at lower, middle, and upper elevations. Specifically, forested middle elevations experienced the most sustained snowmelt at relatively low seasonal average melt rates (~ 5 mm day-1). This unique melt timing and rate may be critical to the local forest ecosystem. Furthermore, the three years evaluated in this study indicate a marked sensitivity of this elevation range to seasonal meteorology, suggesting that it could be highly sensitive to future changes in climate.

Hydrology Seminar – Monday 16 July, 2pm

Dr Taufique Mahmood, of the Global Institute of Water Security and Centre for Hydrology, will present a seminar on
Hydrologic Spatial Patterns in a semiarid Ponderosa Pine hillslopes
on Monday 16 July, 2012, at 2:00pm, in Room 146 Kirk Hall
Ponderosa pine forests are a dominant land cover type in semiarid montane areas. Water supplies in major rivers of the southwestern United States depend on ponderosa pine forests as these ecosystems:
(1) receive a significant amount of rainfall and snowfall,
(2) intercept precipitation and transpire water, and
(3) indirectly influence runoff by impacting the infiltration rate.
However, the hydrologic patterns in these ecosystems with strong seasonality are poorly understood. In this study, we use a distributed hydrologic model to understand hydrologic patterns in a patchy ponderosa pine landscape. Our modeling effort is focused on the hydrologic responses during North American Monsoon (NAM) and winter to summer transitional period.
Our findings indicate that vegetation patterns primarily influence the hillslope hydrologic response during dry summer periods leading to patchiness related to the ponderosa pine stands. The spatial response patterns switch to fine-scale terrain curvature controls during persistently wet NAM periods. Thus, a climatic threshold involving rainfall and weather conditions during the NAM is identified in the hillslope response when sufficient lateral soil moisture fluxes are activated by high rainfall amounts and the lower evapotranspiration induced by cloud cover.
Our findings on the winter to summer transitional period indicate the importance of the relative wetness of each season. For a sequence with a wet winter and a dry summer, a robust snowpack results in abundant soil moisture in the hillslope that persists until the summer season when evapotranspiration consumes it. Under these conditions, the hillslope lateral transport becomes disconnected during the spring transition. We observe an opposite sequence of events when a dry winter is followed by a wet summer period. For each case, the spatial controls on hillslope hydrologic patterns are assessed relative to the terrain and vegetation distributions.
Results from this work have implications on the design of hillslope experiments, the resolution of hillslope scale models, and the prediction of hydrologic conditions in ponderosa pine landscapes. Further, the proposed methodology can be useful for predicting responses to climate and land cover changes that are anticipated for the southwestern United States.
