Roadmap for Sustainable Water Resources in Southwestern North America

by IWA Publishing  (Jul. 8, 2014)

The management of water resources in arid and semiarid areas has long been a challenge, from ancient Mesopotamia to the modern southwestern United States. As our understanding of the hydrological and climatological cycles has improved, and our ability to manipulate the hydrologic cycle has increased, so too have the challenges associated with ...

Linking the management of urban watersheds with the impacts on the receiving water bodies: the use of flow duration curves

by IWA Publishing  (Jul. 16, 2014)

There is growing evidence that changes in the current hydrological behaviour of urbanising catchments are a major source of impacts on the downstream water bodies. However, current flow-rates are rarely considered in studies on urban stormwater management, usually focused on extreme flow-rates. We argue that taking into account receiving water ...

Asian Facility Project - Case Study

by Eijkelkamp Agrisearch Equipment  (Jul. 22, 2014)

Clients Three universities from China: the Xi’an Centre of Geological Survey, China University of Geosciences in Beijing and the Hohai University in Nanjing have set up the Asian Facility Project in cooperation with the UNESCO-IHE Institute for Water Education in Delft and Eijkelkamp Agrisearch Equipment. Project name Asian Facility Project ...

Assessment of relative impact of reservoir location

by IWA Publishing  (Jun. 25, 2014)

Reallocation of reservoir storage capacity for different water use purposes is regarded as one of the representative strategies for supplying water for human and environmental needs under the difficult situation of new reservoir construction. However, there are impacts of reservoir storage reallocation on river/reservoir systems because each ...

Long-term changes in hydrological regime of the lakes in Latvia

by IWA Publishing  (Jun. 18, 2014)

Changes in the hydrological regime of the lakes of Latvia depend on natural and anthropogenic causes. This publication summarises the results of the research on the long-term changes in the water level, thermal and ice regimes in the seven largest lakes of Latvia: Liepājas, Usma, Ķīšezers, Burtnieks, Rāzna, ...

Nationwide hydrological statistics for Sweden with high resolution using the hydrological model S-HYPE

by IWA Publishing  (Jun. 18, 2014)

A first version of nationally covering hydrological statistics for Sweden based on the S-HYPE hydrological model for the period 1961–2010 is described. A key feature of the proposed method is that observed data are used as input wherever such data are available, and the model is used for interpolation in between stations. Short observation ...

Simulation of aquifer-peatland-river interactions under climate change

by IWA Publishing  (Jun. 18, 2014)

Wetlands play an important role in preventing extreme low flows in rivers and groundwater level drawdowns during drought periods. This hydrological function could become increasingly important under a warmer climate. Links between peatlands, aquifers, and rivers remain inadequately understood. The objective of this study was to evaluate the ...

Implementation of a two-way coupled atmospheric-hydrological system for environmental modeling at regional scale

by IWA Publishing  (Jun. 18, 2014)

This work describes the two-way coupling performed between the regional atmospheric model Brazilian Regional Atmospheric Modeling System (BRAMS) and the hydrological model MGB-IPH. As a first step of the atmosphere-hydrology coupling, only the water balance variables were coupled. Differences in temporal and spatial scales between MGH-IPH and ...

Optimal sampling network for monitoring the representative water quality of an entire reservoir on the basis of information theory

by IWA Publishing  (Jun. 5, 2014)

This study presents a method for optimal selection of sampling stations for representative and effective water quality monitoring of a reservoir on the basis of information theory. We adopt an objective function used for the design of other hydrological monitoring networks such as rain gauge networks. Unlike rain gauges, in which only a single ...

Assessing water demands and coverage sensitivity to climate change in the urban and rural sectors in central Chile

by IWA Publishing  (Jun. 5, 2014)

Snow dominated basins in the subtropics are susceptible to climate change, since evaporation and streamflows are affected, impacting key water sectors and increasing the risk of water shortages. This paper shows an integrated assessment of the impacts of climate change on the major water users in the Maipo Basin of Chile, allowing a direct ...
