From ''Stone City'' to ''Hidden Water Region'': Visualize and value the invisible water flows in Matera

This thesis explores the traditional water system of Sassi di Matera and finds out that water plays an important role as a sustainable resource, the social center, and the chance for green space. In addition, by exploring the overall history and culture of Matera, different symbolic elements of water (public fountains, grabiglioni, WWTP) are...

A Hidden Water-Harvesting System: The Sassi de Matera

The water-harvesting system of the ancient Sassi di Matera, in the Basilicata region of southern Italy, represents a clever way of living with water in an arid climate. The terrain, with its soft rocks (Calcarenite di Gravina), provided the foundation for the water-harvesting system that shaped the cave dwellings of Sassi physically, socially...

Long-term assessment of wave conditions and wave energy resource in the Arctic Ocean

It was recently shown that the Arctic has been warming much faster than the rest of the globe during the last decades. This warming has reduced the ice extent significantly, which will strongly impact the wave climate in the Arctic regions, thus affecting the design of marine structures, operations, and energy resources. This study focuses on...

A Numerical Investigation of the Effects of Groove Texture on the Dynamics of a Water-Lubricated Bearing–Rotor System

This paper aims to investigate the combined effects of working condition and structural parameters of groove texture on the dynamic characteristics, stability and unbalance response of a water-lubricated hydrodynamic bearing–rotor system to avoid instability and excessive vibration of the rotor. The Navier–Stokes equation, standard K-ε model...

Colored Water: Designing a resilient landscape framework that facilitates water safety and batik development in Pekalongan city

As one of the most important ecosystems on the planet, the coastal zone accommodates a denser population than the hinterland and faces faster urbanization and higher population growth. Meanwhile, the coastal zone is exposed to several climate change disasters in the context of a sensitive environment dominated by water. It is considered with...

Deterioration of cement mortars with different water cement ratio partially immersed in sulfate

Cement-based materials in sulfate rich areas will suffer from serious corrosion after semi-immersion. To study the degradation of cement mortars with different water cement ratio (w/c) partially exposed to sulfate solution, the mass change were employed to reveal damage progress. Moreover, porosity, erosion products and SO2 4 - content were...

Monitoring vegetation dynamics using vegetation optical depth retrieved from L-band single-incidence angle backscatter observations: A field-based study over corn

Vegetation water content (VWC) is an important parameter for sustainable land and water management. In agriculture, VWC can be used to monitor drought and assess crop productivity. Being able to monitor VWC is important to reduce agricultural vulnerability and scientifically manage agricultural water use. Due to the dense in-situ networks are...

Impact of Soil Moisture and Vegetation Water Content on Backscatter Simulated by WCM at Different Radar Parameters in Maize Field

This paper analysis the effects of soil moisture and vegetation water content (VWC) on total backscattering (σ_tot^0) simulated by water cloud model (WCM) throughout a growth cycle of maize at different frequencies, polarization modes, and incidence angles. Firstly, the bare soil backscatter (σ_soil^0) was simulated by Integral Equation Method ...

Reuse of softening pellet for remineralizing desalinated water

Desalinated water produced by reverse osmosis can generally be characterized as aggressive and corrosive water due to its low pH, low bicarbonate concentration and low hardness. Post treatment is required to remineralize desalinated water to comply with the Drinking Water Guidelines. Softening pellets, a “waste” product from the pellet softening...

Study on mechanism for water pricing

Water resources contribute greatly to human well being, both directly and indirectly. Water resources are irreplaceable natural resources, and are limited. However, due to a growing population and related economic development, the water demand from urban, industry and agriculture has increased dramatically. Water shortage has become one of the...

A Numerical Wave Model for the Refraction and Diffraction of Irregular Waves. Part II: Numerical Experiments of the Wave Model CREON

The numerical wave model CREON is developed to predict the propagation and transformation of wave properties in shallow water. In Gao et al. (1993), which is referred to as Part I in the following, a description is given of the theoretical and numerical treatment of the model. In the present report, we present various computational results. The...
