Groundwater overexploitation in the North China Plain : A path to sustainability
Over-pumping of aquifers is a worldwide problem, mainly caused by agricultural water use. Among its consequences are the falling dry of streams and wetlands, soil subsidence, die-off of phreatophytic vegetation, saline water intrusion, increased pumping cost and loss of storage needed for drought relief.
Groundwater Management in Asian Cities : Technology and Policy for Sustainability
The number of city dwellers who do not have access to piped water and rely on groundwater is also increasing. In many Asian cities, groundwater is not only the source of domestic water but also an important resource for industrial development, making better management of groundwater resources essential for sustainable development. Because groundwater is easier to access and costs less than water from piped systems, groundwater abstraction cannot be easily regulated. Policies for groundwater management adopted in Japan and other Asian countries are compared, and technologies for efficient use of groundwater are elucidated. Groundwater contamination is also a serious problem that exacerbates water scarcity in Asian cities. Case studies illustrate the cause and consequences of naturally occurring contaminants such as arsenic and fluoride, and groundwater contamination due to anthropogenic contaminants is described. Also discussed are technologies for treating contaminated groundwater to reduce the health risks of drinking contaminated groundwater.
Groundwater Geophysics : A Tool for Hydrogeology
Geophysical techniques can map the underground conditions apart from boreholes. The use of these methods for hydrogeological applications is demonstrated for mapping of porous and structural aquifers, determination of groundwater quality (mineralization), assessment of hydraulic properties, determination of aquifer vulnerability and mapping of contaminated sites. Additionally, a description of geophysical techniques used for groundwater studies is given including seismics, resistivity methods, magnetics, ground penetrating radar and NMR (nuclear magnetic resonance).
Groundwater Geochemistry : A Practical Guide to Modeling of Natural and Contaminated Aquatic Systems
Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility-products, are often provided as databases within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration.

Groundwater Dynamics in Hard Rock Aquifers : Sustainable Management and Optimal Monitoring Network Design
Groundwater is of utmost importance in the arid and semi-arid environment. The areas in such regions are forced to face a variety of problems regarding groundwater as it is the main source of water no matter for any use viz., drinking, domestic, irrigation or industrial particularly for the rural population. The main challenges in hard rock areas in the semi-arid region are the water conservation, management and planning of the water resources. This is further complicated with several complexities of the geological formation. With the semi-arid environment, complex geological settings and over shooting stresses, the aquifer system becomes extremely fragile and sensitive. In spite of a good amount of research in this field, it is still needed to understand the behaviour of such complex system precisely and also apply the result in reasonably larger scales.
Groundwater and Ecosystems
Groundwater Dependent Ecosystems (GDEs) frequently exhibit rich biological diversity and can provide enormous economic wealth. In recent years, GDEs in many industrialized countries have shown signs of serious degradation, primarily the result of groundwater abstraction and pollution. Many such systems, including a number of well documented cases in Eastern Europe, are no longer sustainable. As a consequence, the conservation and sustainable management of GDEs has emerged as one of the most urgent environmental research priorities of our time. A large percentage of the world’s population lives in cities and either depends on, or is affected in some way, by groundwater. Moreover, groundwater has become a very important and complex issue that attracts the interest of many diverse stakeholders. Many problems related to groundwater and ecosystems are shared by countries throughout the world and there is growing recognition that much can be gained by co-operation on an international scale.
Groundwater : Resource evaluation, augmentation, contamination, restoration, modeling and management
The demand for water resources is increasing day by day due to ever increasing population, mostly from developing countries. This has resulted in abstracting more water from the subsurface stratum and forcing the water managers to manage the limited groundwater resources in a more scientific way, which in turn needs a more sophisticated way of assessing the underground resource and manage it optimally.

Ground bearing concrete slabs : Specification, design, construction and behaviour
Ground bearing concrete floors, industrial concrete hardstandings and concrete highway pavements have not, in the past, been perceived as a single type of structural element and their construction has taken place independently of each other. This is in spite of their obvious commonality in the areas of design, materials, geotechnical appreciation and construction.
Grippers in Motion : The Fascination of Automated Handling Tasks
