“…The average sediment yield recorded per hydrological year for the present study amounted to 1.8 Mg ha -1 -higher than the rates of 0.5-0.7 Mg ha -1 year -1 reported by Casalí et al (2010), similar to those reported by García et al (2008b) of 1.2 and 3-6 Mg ha -1 year -1 for two small experimental Mediterranean watersheds, but lower than the 6.0 Mg ha -1 year -1 reported by Regüés et al (2000). This variability in soil loss could be attributed to diverse factors (e.g.…”

“…In addition, the N-NO 3 yield in the present experiment (4.2 kg ha -1 year -1 ) was similar to values given in Campbell et al (2004), who reported output values for the stream water of 24 forest watersheds ranging from 0.1 to 5.7 kg ha -1 year -1 (with mean and median of 6.4 and 7.0 kg N ha -1 year -1 , respectively). In contrast, the average yield of dissolved H 2 PO 4 was lower (0.01 kg ha -1 year -1 ) than rates (0.35 and 0.76 kg ha -1 year -1 ) recorded by Casalí et al (2010) for two Mediterranean watersheds.…”

sediment yield from a small watershed in southeastern Spain (Lanjarón): implications for water quality. Hydrological Sciences Journal, 57 (8), 1610-1625. Abstract This study presents an analysis of three hydrological years (2007/08, 2008/09 and 2009/10) of precipitation, runoff and sediment yield collected from a small (669.7 ha) semi-arid watershed in southeastern Spain (Lanjarón). At the watershed outlet the runoff, suspended sediment concentration, total solute concentrations and dissolved nutrients (N-NO 3 , N-NH 4 , H 2 PO 4 and K) in streamflow were continuously monitored. The runoff was highly variable, ranging between 53.4 and 154.7 mm year -1 , with an average of 97.6 mm year -1 . In contrast, sediment yields were more regular, averaging 1.8 Mg ha -1 year -1 . The hydrological response of the watershed depended mainly on rainfall intensity. Formerly, 32% of the watershed was forested and runoff was more regular, despite the typical Mediterranean rainfall cycle; however, due to forest area reduction to 17% and the increase in abandoned farmland area (18%) in recent decades, the runoff variability has increased. Greater amounts of solutes (32.7 Mg ha -1 year -1 ) were exported, so that this water is considered as poor for irrigation use. The temporal nutrient export was related to seasonal discharge fluctuations as well as daily concentrations. In addition, the nutrient concentrations of the water discharged were lower than threshold limits cited in water-quality standards for agricultural use and for potable water, with the exception of K (65.9 mg L -1 ), which may degrade surface waters as well as irrigated soils. Thus, hydrological and erosive processes depended on the watershed features, but also on prior conditions in combination with the characteristics of rainfall episodes. Runoff and sediment yield from a small watershed in southeastern Spain 1611 qualité de l'eau pour un usage agricole ainsi que pour l'eau potable, à l'exception de K (65,9 mg L -1 ), ce qui peut dégrader les eaux de surface ainsi que les sols irrigués. Ainsi, les processus hydrologiques et érosifs dépendent des caractéristiques du bassin, mais aussi des conditions antérieures, combinées aux caractéristiques des épisodes pluvieux.

“…As for rural settlements and rural land for affiliated facilities, the land uses of breeding livestock and poultry and residential activities would also cause heavy non-point pollution if not treated properly (Casali et al, 2010;Seeboonruang, 2012), so the layout and construction of the disposal facilities for living garbage and livestock and poultry manure are of great importance in Huang-Huai-Hai Plain. The location of village garbage and sewage collection, storage and disposal places must be distributed properly in order to connect with the garbage and sewage treatment facilities of the town and the city.…”

Land use transitions and their effects on water environment in Huang-Huai-Hai Plain, China

a b s t r a c tThis paper analyzes the spatio-temporal dynamic patterns of land use in Huang-Huai-Hai Plain, one of the China's most important grain production bases experiencing rapid urban-rural transformation development, using high-resolution Landsat TM (Thematic Mapper) data and series data of water environmental quality monitoring in 2000 and 2010, and related socio-economic data from government departments. After assessing the change of water environmental quality of Huang-Huai-Hai Plain during 2000-2010, three spatial econometric regression models including Spatial Lag Model (SLM), Spatial Error Model (SEM) and ordinary least squares (OLS) are used to explore the correlationships between land use transitions and water environmental changes. The outcomes indicated that, during the research period, land use pattern changes in the study area were characterized by the loss of large quantities of farmland and the increase of construction land and water body. On the whole, the water environment in the study area was obviously improved, but there also existed partial deterioration as evidenced by the increase of monitoring sections with water environmental quality below Class V. In general, the increases of grassland, forested land and water body have positive effects on water environmental quality while farmland and construction land have negative effects on that. The authors argue that construction land use and farmland use have almost equal negative effects on water environmental quality, and managing agricultural non-point source pollution is pivotal to improve local water environmental quality. Finally, some of the major implications for managing the land and water resources in the plain areas of China as well as other developing countries undergoing rapid urban-rural transformation development are discussed in the aspects of ecological farming practices, rural construction land management, land use planning and urban planning.

“…Así, a nivel de cuenca, la relación entre la descarga y la producción de sedimentos cambiará según las características climáticas (Vega et al, 1998;Singh et al, 2004); pudiendo presentar, incluso, importantes variaciones estacionales (p.ej., Gregory y Walling, 1973;Van Dijk y Kwaad, 1996;Casalí et al, 2008Casalí et al, , 2010. Más aún, la salida de sedimentos en una cuenca estará también ampliamente determinada por las características de los diferentes eventos de lluvia y escorrentía, por las condiciones superficiales (Steegen et al, 2000) y contenido de humedad antecedente (Seeger et al, 2004) de los principales suelos, por el tipo de proceso erosivo dominante (ej., erosión laminar o por cárcava) (Regües et al, 2000), etc.…”

“…Igualmente, los pastos e incluso una cubierta densa de matorral pueden ser tan eficaces en reducir la tasa de erosión como lo sería el bosque. Aún así, un inadecuado manejo forestal puede dar lugar a pérdidas de suelo elevadas; aún superiores, incluso, a las registradas en terrenos cultivados con cereales (Casalí et al, 2010).…”
