Lecture by Birdsdall-Dreiss Award winner: Ed Harvey

Friday June 30th, Ed Harvey will give a lecture at UNESCO-IHE, Delft (start 16:00h). Ed Harvey is the 2017 Birdsdall-Dreiss Award winner. Further information about Ed Harvey and the award can be found here.

When – Friday 30 June 
16:00 – Birdsall-Dreiss Distinguished Lecture
17:00 – Reception

Where – IHE Delft Institute for Water Education, Westvest 7, 2611 AX Delft The Netherlands (Google Map)

The Birdsall-Dreiss Lectureship began in 1978, as part of a bequest left to the Geological Society of America – Hydrogeology Division.  The bequest is used to provide travel funds for outstanding scientists working in the field of hydrogeology to visit other institutions and give talks on their research.

About the Lecture – On August 25, 1916, President Woodrow Wilson signed the act creating the National Park Service, a new bureau in the Department of the Interior. This “Organic Act” directed the Park Service “to conserve the scenery and the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.” This conservation, enjoyment and protection mandate also applies to water resources within parks.

 Unlike most park resources, that are located largely within park boundaries, or are completely under the management control of the National Park Service, park water resource issues and management often involve greater challenges. These challenges arise from the fact that surface water and aquifer boundaries often extend beyond park boundaries and because the legal authority to allocate and manage water resources typically resides with the states. Thus, parks often need to consider resource issues at a larger landscape, or seascape scale, and manage collaboratively with neighbors and partners to protect, manage and restore water resources. In addition, water resource expertise is not always available within a park, resulting in the need to partner with other agencies, universities, friends groups, or regional and national offices. Lastly, many park water resource issues have broader legal, political, socioeconomic, and cultural implications requiring park managers to consider more than just the science alone when making a water resource management decision. 

The lecture, using a series of examples from various parks across the United States, will explore the process of how parks identify water resource needs, issues and concerns, and how they develop and apply the necessary scientific information needed to make water resource management decisions. Specific challenges to decision making and park water resource management will be presented and explored including trans-boundary issues, partnership building, scientific uncertainty, funding and personnel/expertise, and making science-based decisions that also appropriately consider the legal, political, socioeconomic, and cultural impacts of the decision. As part of the visit, the lecturer will also present future water resource research and management needs in parks and across the nation, present information about engaging in water resources research within parks, and advise students on programs for seasonal and permanent employment as a water resource professional within the National Park Service.


Darcy Lecture 2016 by Prof. Dr. Ty Ferré

“Seeing Things Differently: Rethinking the Relationship Between Data, Models, and Decision-Making”

Wageningen University, May 24 10:00 in Orion building, Room C3033, Adress Bronland 1, 6708 WH, Wageningen

Practicing hydrogeologists construct detailed numerical models to predict the responses of hydrologic systems to natural and applied stresses. These predictions form the basis for decisions that must balance optimal use of resources and ecosystem support. These decisions typically involve multiple interested parties with strongly differing priorities for water allocation. Despite the importance that stakeholders place on water resources, budgets for hydrogeologic studies are often limited. As a result, the hydrologic models used for decision support are severely data limited. This requires improved methods to identify the optimal set of observations to collect and to use model-predictions to support robust decision-making under considerable uncertainty.

International Workshop on Catchment Hydrological Modeling and Data Assimilation

Date: 8-13 July, 2012
Location: Faculty of Geo-Information Sciences and Earth Observation of the University of Twente, Enschede

The 5th International Workshop on Catchment Hydrological Modeling and Data Assimilation (CAHMDA-V) is a follow-up to the successful CAHMDA-I workshop held in Wageningen (2001), CAHMDA-II workshop held in Princeton (2004), CAHMDA-III workshop held in Melbourne (2008), and the CAHMDA-IV workshop held in Lhasa (2010). The objective of the workshop is to assess recent advances in modeling, observing, and data assimilation approaches to improve understanding, observing and predicting hydrological processes and catchment evolutions. Particular attention will be given to the quantification and attribution of climate change impacts, vulnerability and adaptations in river basins. New observing systems and new theories and the use of data assimilation are probed in setting the research agenda in hydrological researches for the coming decade. Invited key notes, short poster presentations and extensive discussions will be main forms of the workshop. Pre-workshop data assimilation training course and post-workshop excursions will be organized.

Darcy Lecture: “Development of Reliable Hydrologic Data Sets in Difficult Environments: Case Studies from Benin, West Africa”

Stephen E. Silliman, Ph.D.

16 September 2011, 10:00-11:00h

Princetonlaan 6

Reliable hydrologic data are critical for sound hydrogeologic analyses and for the subsequent policy decisions based on those analyses. Obtaining such data sets in the face of limited budgets and limited access to field sites can be a daunting challenge, particularly in rural regions in developing countries. Experience in Benin demonstrates that such challenges are best met through close collaboration with a number of in‐country entities (universities, local populations, government agencies, and NGOs) and integration of hydrologic expertise with political political, social, and cultural considerations.

This presentation focuses on a series of case studies from Benin directed at developing data sets involving: (1) regional water quality, (2) temporal variation in nitrate contamination in rural groundwater wells and (3) temporal variation in hydraulics and wells, water quality related to saltwater intrusion as well as anthropogenic contamination in coastal areas. This presentation demonstrates both the value of statistical analysis in the design and implementation of sampling plans in these difficult environments, as well as the power of close collaboration with in‐country colleagues and local populations
