Effects of multi-layering in a classical pumping test

To demonstrate several techniques for the analysis of pumping tests in confined aquifers Vedat Batu (1998) presents Example 4-6 on page 160–161 of his book «Aquifer Hydraulics». The pumping well (Q = 540 m3/d) and the two observation wells (r = 25 m and r = 75 m) are fully penetrating. Resulting transmissivities and storativities of the various methods are found between T = 174 and 260 m2/d, and between S = 0.000135 and S = 0.000666. All methods show a rather poor fit, mainly because the measured drawdown rate during the first 30 minutes is clearly higher than in the later period of the test. A much better fit can be obtained when the data of both observation wells are analyzed with the MLU software and a two-aquifer (analytical) model is used.

 
Towards a Method of Participatory Planning in an Emerging Metropolitan Delta in the Context of Climate Change – new PhD thesis

Urbanizing deltas are subjected to pressures related to urban growth and climate change, within a context of uncertainty and unpredictability. Those pressures interact at multiple scales and temporalities, affecting the components of the systems, as well as the relations between them and with the environment. This complexity reveals the need for the society (including governments, institutions, civil organizations, academia, etc.) to enhance the adaptability of the system of the delta, in order to cope with changes without losing their substantial characteristics. The PhD thesis of Verónica Zagare is focused on the study of the complexity of self-organizing processes that emerge in metropolitan areas located in (or near) delta territories, in order to link climate adaptation with urban development from an actor-oriented perspective.

 
Bridging the floods − The role of social learning for resilience building in urban water services

The development of cities is increasingly threatened by a worldwide water crisis. Urban water services (including drinking water, sanitation and drainage) are facing complex and multiple pressures, which are becoming increasingly frequent and severe. These pressures include floods, and the depletion, pollution and degradation of water resources and their associated ecosystems. These diverse pressures fall mainly within the domains of flood risk and water resources management: two working fields that are divided by different institutional structures, approaches and practices. Social learning is becoming increasingly popular as an approach that has the potential to “bridge” these silos, and ultimately, contribute to building resilience in urban water services. However, empirical analyses on this issue are rare and fragmented. In her PhD thesis, Åse Johannessen fills this gap. Her results identify challenges to the integration of the identified silos, what resilience means for urban water services, and the key elements of social learning that can support or inhibit urban water resilience.

 
Angela Renata Cordeiro Ortigara: make better use of water data

With less and less people on the ground, and less and less ground truth and real data on water – be it quality, levels or discharges – more and more policy and statements are being made that are unsupported by reality. Researchers and UN organizations such as WMO keep stressing the need for better (use of) data by decision-makers in order to prevent that ‘measures’ that have lost a connection with reality. Data, implementation of SDG 6 (clean water and sanitation for all), and linking with everyday needs of the communities are key issues, according to Dr Angela Renata Cordeiro Ortigara.

 
Water Resources of Jordan • new book

One of the major challenges facing Jordan is its severe shortage of water resources: water scarcity is the norm. The consequences of water scarcity in Jordan are made more harsh by several developments related to strategy, policy and society, the most significant being the rapid rise in population. The population of Jordan has increased tenfold since the 1950s. In addition to the high rate of population growth, Jordan has seen a series of massive refugee influxes since 1948, most importantly the influx of Palestinian refugees over the past decades and currently over a million Syrian refugees. A new book, «Water Resources of Jordan», sheds light on the problems Jordan faces and aims to bring suggestions for possible solutions. 

 
Groundwater as a Buffer to Climatic Change: Dynamic Subsurface Storage of Glaciated Landscapes

29 June 2018 • The northeastern United States is experiencing rapid changes in its hydrology due to intense land-use change, urbanization, and climate change. It also possesses some of the highest density, longest term observations of hydrologic variables (streamflow, groundwater levels) in the US and the world. The focus of this presentation is how small unconfined aquifer systems, and the streams to which they are connected, respond to hydroclimatic and land use changes. 2018 Birdsall-Dreiss Lecture: Groundwater as a Buffer to Climatic Change: Dynamic Subsurface Storage of Glaciated Landscapes

 
Groundwater around the world – free download

The book »Groundwater around the world« presents a unique and up-to-date summary of what is known about groundwater on our planet, from a global perspective and in terms of area-specific factual information. Unlike most textbooks on groundwater, it does not deal with theoretical principles, but rather with the overall picture that emerges as a result of countless observations, studies and other activities related to groundwater in all parts of the world. The focus is on showing the role and geographical diversity of groundwater—a natural resource of great importance in daily life, but poorly understood by the general public and even by many water sector professionals. As a result of a cooperation between author Jac van der Gun and Michael van der Valk | Hydrology.nl the book is now available as a free PDF file!

 
Життя без сміття і з чистою водою. Чим дивує приїжджих Чехія

Питна вода з-під крана, всі на велосипедах і відсутність поняття «сміття». Про те, що для українця – дивина, а для жителя невеличкого чеського міста – буденність, розповіла кореспонденту «СК» харківська науковиця Юлія Виставна.
