Description: DICAM Dipartimento di Ingegneria Civile, Chimica, Ambientale e dei Materiali ALMA MATER STUDIORUM Università di Bologna, Bologna, Italy. In the northern Apennines of Italy, springs are quite widespread over the slopes. Due to the outcropping of low-permeability geologic units, they are generally characterized by low-yield capacities and high discharge variability during the hydrologic year. In addition, low-flow periods (discharge lower than 1 Ls-1

By: R. Tassi; D. G. Allasia; F. Lorenzini

Description: Federal University of Santa Maria, Santa Maria, Brazil. In the last decades, new approaches were adopted to manage stormwater as close to its source as possible through technologies and devices that preserve and recreate natural landscape features. Green Roofs (GR) are examples of these devices that are also incentivized by city's stormwater management plans. Several studies show that GR decreases on-site runoff from impervious surfaces, however, the an...

Description: College of Hydrology and Water Resources, Hohai University, Nanjing 210098, China. Accurate and reliable drought monitoring is of primary importance for drought mitigation and reduction of social-ecological vulnerability. The aim of the paper was to propose a short-term/long-term composited drought index (CDI) which could be widely used for drought monitoring and early warning in China. In the study, the upper Huaihe River basin above the Xixian gauge s...

By: M. Arif; J. Husain; I. Husain

Description: Public Health Engineering Department, Rajasthan, Bhilwara, 311001 India. Rajasthan is well known for its Great Thar desert. Central Rajasthan has an arid to semi-arid environment. The area faces either scarcity of water or poor quality of drinking water. In some areas water is transported 2 km or more, which uses time, energy and money. Rich people have their own sources, which is restricted for use by others. Such conditions are affecting socially-deprived ...

Description: Himalayan Cryosphere, Climate and Disaster Research Center, Kathmandu University, Dhulikhel, Nepal. Glaciers in the Himalayan region are often covered by extensive debris cover in ablation areas, hence it is essential to assess the effect of debris on glacier ice melt. Seasonal melting of ice beneath different thicknesses of debris on Lirung Glacier in Langtang Valley, Nepal, was studied during three seasons of 2013–14. The melting rates of ice under 5 cm de...

Description: Department of Hydraulics and Sanitary Engineering, University of São Paulo, 400 Trabalhador são carlense av., São Carlos, Brazil. Groundwater is an important part of the hydrological cycle, accounting for more than 25% of human needs on the global scale. As a result of aquifer overexploitation associated with climate change, even in the most conservative future climate scenarios, mean water-table levels can experience drastic drops. Although there are effort...

By: G. Lindström; B. Arheimer

Description: Swedish Meteorological and Hydrological Institute (SMHI), 60176 Norrköping, Sweden. The most radical anthropogenic impact on water systems in Sweden originates from the years 1900–1970, when the electricity network was developed in the country and almost all rivers were regulated. The construction of dams and changes in water flow caused problems for ecosystems. Therefore, when implementing the EU Water Framework Directive (WFD) hydro-morphological indicator...

Description: China Institute of Water Resources and Hydropower Research, Beijing, 100038, China. Many factors influence irrigation water requirement on the basin scale, which make it difficult to obtain comprehensive data. Despite the advantage of less needing historical data, the prediction precision of traditional trend prediction methods is hard to guarantee. For water scarce basins, the artificial influence on irrigation requirement should be thought of as important ...
