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.

More information about the STW Open Mind award and the about the idea of Ruud can be found on the website of STW.

Boussinesq Summer Event 2016: Amsterdam

On Friday July 8 the Boussinesq Spring/Summer event was held at the Vrije Universiteit Amsterdam. During the morning session exciting talks by Hugo de Boer (carbon and water fluxes by plants), Josh Dean (carbon in rivers) and Monique Heijmans (carbon in peat soils) set the stage for an inspiring day on the theme Water and Carbon with 29 participants.

After lunch we departed to the Ilperveld. Here we boarded for a 2 hour boat trip through this amazing peatland complex. Michel Hensens guided us through the history of the region. Surprisingly, the now scenic wetlands appeared to have a long history as waste dumpsite of the city of Amsterdam, including being a dump site for hospitals up to the late 1950s. Michel explained how this pollution, which is still in the ground, is being managed and how this improved the botanical and water quality of the area during the last decades.

Halfway the tour, we met up with Ko van Huissteden. Ko explained what equipment he and his research group use in the Ilperveld to measure carbon fluxes coming from peat in order to establish if this site is a net source or sink of green house gases. At 5 o’clock we were back at the Vrije Universiteit, nicely in time to finish the day with well-deserved drinks and snacks.

50th anniversary symposium “State of the art measurements of catchment-scale hydrological processes”

On the occasion of the 50th anniversary of the Hydrology and Quantitative Water Management Group at Wageningen University and the 50th anniversary of the Hupsel Brook experimental Catchment, we organize a scientific symposium with the theme “State of the art measurements of catchment-scale hydrological processes” on Thursday 10 September. The symposium is organized within the framework of the Euromediterranean Network of Experimental and Representative Basins (ERB), the Netherlands Hydrological Association (NHV) and the Boussinesq Center for Hydrology.

The symposium will consist of five sessions, covering five main themes: precipitation, evaporation, soil moisture, groundwater and discharge, with special focus on closing water budgets. Each session will contain an international keynote and two invited speakers from (near) the Netherlands.

In addition, there will be a (Dutch) symposium and reunion on Friday 11 September, highlighting 50 years of research and education in the Hupsel Brook catchment and at the Hydrology and Quantitative Water Management Group.

When: Thursday 10 September 2015 (English symposium) and/or Friday 11 September 2015 (Dutch symposium + reunion)
Where: Campus Wageningen University
Cost: None
Registration: Email before 15 August to tamara.schalkx@wur.nl

Boussinesq Summer Event 2015

On Wednesday August 26th the second Boussinesq Spring event was held in Delft. Twenty three participants enjoyed the lectures of Nick van de Giesen, Pieter Stuyfzand, and Ype van de Velde on the theme “Towards long-term hydrological sites?”. After lunch, we made a walk, via the Boussinesqweg, to the laboratories of Deltares. After some coffee we got a tour through the immense hydraulic lab, the geotechnical lab, and a glimpse on the brand new ‘Delta-goot’. The BBQ was canceled due to the hydrological weather, so the day was ended with drinks and indoor pizzas.

1st Boussinesq Spring meeting 2014

(by Lieke Melsen)

10154328_10154037373890424_1361078170972517731_n

On Monday the 7th of April the first Boussinesq Spring meeting took place. Especially organised for young and early-career scientist, but of course everyone with a scientific background in hydrology was welcome. The meeting, held at Wageningen University, started off with an interesting presentation from Bob Sue (ITC) on land surface fluxes. After the key note the first pitch round started, with only 2 minutes per presentation. The pitch round was a perfect opportunity for all participants to present their current research, ask for advice, shameless advertise the EGU poster or talk, or just to drop an idea. There was a large variety in the talks and the response of the public on the pitch-concept was exclusively positive. There were just some people that had difficulties with sticking to the two-minutes limit…

After a long break with coffee, tea, and chocolate-eggs for the spring feeling, the morning continued with a presentation from Miriam Coenders on a novel method to estimate surface fluxes and a presentation from Bram te Brake on the use of satellite data to identify clay swelling and shrinkage. Again, this part of the day was closed with a 2-minutes-pitch round.

After three presentations and sixteen pitches, it was definitely time for a good lunch. On long tables we enjoyedthe soup, the muffins, the sandwiches and the fresh fruit, to gain some energy again for the afternoon excursion.

For the excursion, a visit to the Speulderbos-site was planned. After a bus trip and a nice walk through one of the oldest forests of the Netherlands, we reached the measurement site and the flux tower. It was a pity that RIVM had just decided two months earlier to remove most of the measurement equipment, but with some fantasy we could imagine the equipment on the tower ourselves. And of course, there was still the possibility to go to the top of the tower! Some sportive people chose to go up in the tower with the stairs, but also the comfortable option (the elevator) was used to enjoy the view on top of the tower. We were lucky with the nice weather and the views were stunning! The whole program of the day was in the end slightly delayed and therefore we had to skip the afternoon discussions, but of course there was plenty of time for an informal drink to have a chat with all the attendees. The goal of this day, to meet some colleague-scientists and to exchange ideas, was definitely achieved!
