Quadratic polynomial regression models were established for 5 pure tree (Pinus massoniana Lamb) plots between vegetation fractional coverage (VFC) and soil/waterconservation effects (SCE/WCE) for 144 erosive rainfall events from 2007 to 2010
in Hetian Town, Changting County, Fujian Province. In general, the effects on soil conservation on the plots were more notable than those on waterconservation. The critical VFCs for soil and waterconservation during rainfall events were 0.4 and 0.5
, respectively, which provided a reference for the evaluation and planning of forest reconstruction in this and similar water-eroded areas.

classification into five phases of water management. The examination then addresses the main aspects of the WFD experience in the Douro, exploring elements of innovation and continuity. Higher concern for environmental conservation and the detailed assessment
The article discusses the challenges and prospects of implementing the Water Framework Directive (WFD), one of the most comprehensive pieces of environmental legislationpassed by the European Union (EU). The translation of the WFD into policy-making
is analysed through a case study – which combined interviews, participant observation and the attendance of public events – in the Portuguese section of the Douro River Basin. The evolution of water regulation is initially considered according to a suggested
of water management problems are significant improvements that followed the introduction of the WFD. However, the same institutional reforms have also served to consolidate techno-bureaucratic approaches centred on the economic values of water. As a result
, the rationality and failures of the new water regulation prompted unexpected opposition from various stakeholder groups, such as farmers, non-governmental organisations (NGOs) and urban water customers. The success of the WFD is directly dependent on the ability
to perceive the politicised complexity of water management and on effective mechanisms of dialogue and social inclusion.

Precipitation, throughfall, stemflow and soil water content were measured, and interception, transpiration, evaporation, runoff, deep percolation and soil water recharge were estimated in the natural Liaotung Oak forestlands in the hill and gully
region of the China Loess Plateau. Four stands (south- and north-facing slopes) of 2 forests were studied between May 27, 2006 and October 31, 2007. Hydrological fluxes were calculated using a coupled water and heat flow model called CoupModel
. Throughfall, stemflow and soil water content were used to calibrate the model. The simulations indicated that, interception, vegetation, transpiration and soil water evaporation were the main components of water consumption in the 4 stands, accounting
for about 90% of the precipitation. The water budget differences among the 4 stands indicate that care is required for properly selecting regrown tree-species.

This paper analyses the effect of water storage and soil moisture conservation by means of micro-water-collecting technique in the dryland field of spring maize. This technique not only has the function of regulating and adjusting the amount
and distribution of field evapotranspiration, but also can raise the water use efficiency, which results in an obvious effect of increasing crop yield, especially in the dry years.

data sets are more effective in assessing the impacts of conservation buffers and grasslands on water quality through hydrologic modeling.
A methodology was developed using the object-based image analysis approach with Landsat-5 TM imagery of the year 2005 and thematic layers of streams to quantify conservation buffers and grasslands (OBIA-2005). The OBIA-2005 land cover data was used
Indiana. The combination with the width of edge-of-field buffer strips module of the SWAT model achieved the largest TP loads reduction. These findings demonstrate that improved representation of vegetative conservation practices in geospatial land cover

The paper explores the tensions and complexities experienced by water companies in England and Wales as they attempt to meet the contradictory legislative requirements. A simple model is used to explore the effect of increasing effluent quality
on power consumption and hence carbon emissions. In addition to complexities within the EU Water Framework Directive and UK Climate Change Act, water companies are restricted by the regulatory framework of the UK water industry and additional policies
