By: M. Mastrocicco; N. Colombani; E. Salemi; G. Castaldelli; V. G. Aschonitis

Description: University of Ferrara, Department of Life Sciences and Biotechnology, Ferrara, Italy. LOS indices (abbr. of Losses) can be used for the assessment of the intrinsic vulnerability of agricultural land to water and nitrogen losses through percolation and runoff. The indices were applied on the lowland region of Ferrara Province (FP) in Italy and the upland region of Sarigkiol Basin (SB) in Greece. The most vulnerable zones in FP were the coastal areas consistin...

By: L. Prasad Devkota; A. Bhakta Shrestha; T. Raj Adhikari

Description: Central Department of Hydrology and Meteorology, Tribhuvan University, Kathmandu, Nepal. General Circulation Models (GCMs) successfully simulate future climate variability and climate change on a global scale; however, poor spatial resolution constrains their application for impact studies at a regional or a local level. The dynamically downscaled precipitation and temperature data were used for the future climate scenarios prediction for the period 2000–205...

By: E. Schiavo Bernardi; R. Tassi; R. Basso; D. Allasia; P. Freitas Ferreira

Description: University of Santa Maria, Programa de Pós-graduação em Engenharia Ambiental, Santa Maria, Brazil. The lack of rainfall data in Brazil, and, in particular, in Rio Grande do Sul State (RS), hinders the understanding of the spatial and temporal distribution of rainfall, especially in the case of the more complex extreme events. In this context, rainfall's estimation from remote sensors is seen as alternative to the scarcity of rainfall gauges. However, as ...

By: C. O. Galvão; G. N. S. Silva; A. C. S. Silva

Description: Federal University of Campina Grande, Campina Grande, 58429-900, Brazil. Extreme events are part of climate variability. Dealing with variability is still a challenge that might be increased due to climate change. However, impacts of extreme events are not only dependent on their variability, but also on management and governance. In Brazil, its semi-arid region is vulnerable to extreme events, especially droughts, for centuries. Actually, other Brazili...

Description: Department of Biological and Agricultural Engineering, Kansas State University, 129 Seaton Hall, Manhattan, Kansas, USA. Ephemeral gully (EG) erosion can be a major source of sediment in agricultural watersheds and predicting the location and length of EGs is important to assess sediment source areas. Topographic index (TI) models utilize topographic-only factors to locate concentrated flow paths on agricultural fields. In this paper, the TI-model is expande...

Integration of Uncertainties in Water and Flood Risk Management : ...

By: B. Höllermann; M. Evers

Description: Department of Geography, University of Bonn, Bonn, Germany. Water management is challenged by hydrological and socio-economic change and hence often forced to make costly and enduring decisions under uncertainty. Thus, thinking beyond current acknowledged and known limits is important to consider these changes and the dynamic of socio-hydrological interactions. For example, reservoir management aiming at flood reduction and mitigation has to cope with m...

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 Geography, Louisiana State University, Baton Rouge, Louisiana 70803, USA. Lakes within the Colville River delta in northern Alaska, USA, vary in size from small ponds created by ice-wedge growth to thaw lakes that are as much as three kilometres long and ten metres deep. As the river migrates, lake edges are breached and the lakes are drained. Such lake tapping is aided by permafrost thaw and ice wedge melt and, in the case of the larger lakes,...

By: X. L. Jiang; H. Bu; Z. M. Liang; Y. M. Hu

Description: College of Hydrology and Water Resources, Hohai University, Nanjing, China. In this paper, a novel approach for non-stationary hydrological frequency analysis is proposed. The approach is due to the following consideration that, at present the data series used to detect mutation characteristic is very short, which may only reflect the partial characteristic of the population. That is to say, the mutation characteristic of short series may not fully repr...

Description: CSIRO Land and Water Flagship, GP.O. Box 1666, Canberra, ACT 2601, Australia. Most of the forested headwater catchments are an important source of water supply in many parts of the world. A prime example is southeast Australia where forests supply major river systems and towns and cities with water. It is critical for an informed and adaptive water resource management to understand changes in streamflow caused by vegetation changes in these headwater fo...
