Description: State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering, College of Hydrology and Water Resources, Hohai University, No. 1 Xikang Road, Nanjing, 210098, China. River flow regimes in the semi-arid region of northern China show a decreasing trend in terms of quantity. River runoff (i.e. blue water) reduction within the Laohahe catchment, the source area of the Liaohe River basin, manifests the aridity that exists widely in northern China. A...

Effects of Minor Drainage Networks on Flood Hazard Evaluation : Vo...

By: A. Domeneghetti

Description: School of Civil, Chemical, Environmental and Materials Engineering, DICAM, University of Bologna, Bologna, Italy. Scientific literature reports a plethora of numerical tools of different complexity (e.g. 1D, 2D raster-based or full 2D models) for flood hazard and flood risk evaluation. The correct identification of the appropriate model still represents a key aspect in the overall flood hazard process even though the potential of these modelling instruments ...

By: D. A. N. Vieira; M. E. Ursic; E. J. Langendoen; S. M. Dabney; R. R. Wells

Description: US Department of Agriculture, Agricultural Research Service, National Sedimentation Laboratory, PO Box 1157, Oxford, MS 38655, USA. On cropland, ephemeral gully erosion in the USA may contribute up to 40% of the sediment delivered to the edge of the field. Well-tested, physically- and process-based tools for field and watershed scale prediction of gully erosion are lacking due to the fact that the complex nature of migrating headcuts is poorly understood. Un...

Towards Worldwide Height Unification Using Ocean Information : Vol...

By: C. W. Hughes; P. L. Woodworth

Description: National Oceanography Centre, Joseph Proudman Building, 6 Brownlow Street, Liverpool L3 5DA, UK. This paper describes how we are contributing to worldwide height system unification (WHSU) by using ocean models together with sea level (tide gauge and altimeter) information, geodetic (GPS and levelling) data, and new geoid models based on information from the GRACE and GOCE gravity missions, to understand how mean sea level (MSL) varies from place to place alo...

By: L. Zhai; J. Hunter; T. S. James; B. Greenan; G. Han

Description: Bedford Institute of Oceanography, Fisheries and Oceans, Canada. This paper documents the methodology of computing sea-level rise allowances for Atlantic Canada in the 21st century under conditions of uncertain sea-level rise. The sea-level rise allowances are defined as the amount by which an asset needs to be raised in order to maintain the same likelihood of future flooding events as that site has experienced in the recent past. The allowances are determi...

Combining Hydraulic Model, Hydrogeomorphological Observations and ...

By: S. Van-exter; S. Pistre; N. Bourgeois; F. Raynaud; V. Borrell-estupina; A. Dezetter; E. Servat

Description: University of Montpellier/IRD/CNRS – UMR5569, HydroSciences Montpellier, 2 Place Eugène Bataillon, 34095 Montpellier CEDEX 5, France. During a flood event over a karst watershed, the connections between surface and ground waters appear to be complex ones. The karst may attenuate surface floods by absorbing water or contribute to the surface flood by direct contribution of karst waters in the rivers (perennial and overflowing springs) and by diffuse resur...

Reliability of a Conceptual Hydrological Model in a Semi-arid Ande...

By: P. Hublart; D. Ruelland; I. García De Cortázar Atauri; A. Ibacache

Description: UM2, UMR HydroSciences Montpellier, Montpellier, France. This paper explores the reliability of low-flow simulations by conceptual models in a semi-arid, Andean catchment (30° S) facing climate variability and water-use changes. Depending on water availability, a significant part of surface water resources are diverted to meet irrigation requirements. In return, these water withdrawals are likely to influence the hydrological behavior of the catchment. ...

Description: CNRS, HydroSciences Laboratory, Place Eugene Bataillon, 34095 Montpellier, France. This study assesses water stress by 2050 in river basins facing increasing human and climatic pressures, by comparing the impacts of various combinations of possible future socio-economic and climate trends. A modelling framework integrating human and hydro-climatic dynamics and accounting for interactions between resource and demand at a 10-day time step was developed an...

Description: Institute of Geography, Russian Academy of Sciences, Staromonetny lane, 29, 119017 Moscow, Russia. An approach is presented for carrying out a long-term projection of river runoff changes in large Russian river basins in the first three decades of the 21st century. These changes may be caused by climate warming and socio-economic factors. The approach utilizes a method for scenario estimation of runoff changes with a range of possible climate warming effects...

Description: Technische Universität Dresden, Institute of Hydrology and Meteorology, 01069 Dresden, Germany. The conventional methods used to solve multi-criteria multi-stakeholder problems are less strongly formulated, as they normally incorporate only homogeneous information at a time and suggest aggregating objectives of different decision-makers avoiding water–society interactions. In this contribution, Multi-Criteria Group Decision Analysis (MCGDA) using a fuzzy-sto...

By: G. Petrucci; J.-f. Deroubaix; B. Tassin

Description: Vrije Universiteit Brussel (VUB), Earth System Sciences (ESSc), Brussels, Belgium. Stormwater source control is becoming a common strategy for urban stormwater management in many countries. It relies on regulations or other policy instruments compelling or inciting implementation, for each new urban development, of small-scale facilities to locally store and manage stormwater. Local authorities that pioneered source control since the 1980s have already obser...
