is considered to be responsible for the observed increasing trends of water discharge in the dry-season and decreasing trends of sediment load after 1986, and for the latter, reforestation program in the catchment is another contributing factor. The distinct
groundwater sensors were installed for the corporation project between China and Japan. Combined with the monitoring results from 2004 to 2006 with the major factors affecting the dynamic patterns of groundwater, such as topography and landform, depth
of groundwater level, exploitation or discharge extent, rivers and lakes, the dynamic regions of NCP groundwater were gotten. According to the dynamic features of groundwater in NCP, 6 dynamic patterns of groundwater level were identified, including discharge
along the Yellow River and infiltration-discharge-evaporation pattern in the littoral plain. Based on this, the groundwater fluctuation features of various dynamic patterns were interpreted and the influencing factors of different dynamic patterns were

A field study was conducted to analyze root throw and associated sediment transport in Haw Creek Watershed, Canadian Rockies. A large crown fire in 2003 allowed the opportunity to study pre-fire and post-fire root throw. A tree population dynamics
model is integrated with a root throw transport model calibrated for the Canadian Rockies to examine the temporal dynamics of sediment transport. Fire is incorporated as a disturbance that initiates development of a new forest, with the model cycling
through generations of forest. Using this integrated model, the AA. strive for improved understanding of how tree population dynamics driven by wildfire disturbance influences the temporal dynamics of sediment transport due to root throw in the Canadian
The paper seeks to renegociate the role of visuals and visual practice within the tourist experience. The A. explores the ways in which visuals (photography) enliven tourists' becoming through a multiplicity of fluid and dynamic performances
, practices and processes. The emerging dynamics of visual practice renegociate new understandings between tourists and place to establish a series of conceptual moments.
The complex nonlinear systems with fractal as well as chaotic dynamics of annual runoff processes in the three headwaters of the Tarim River
. The main findings are : 1) the annual runoff processes of the 3 headwaters of the Tarim River are complex nonlinear systems with fractal as well as chaotic dynamics; 2) the correlation dimensions of attractor derived from the time series of the annual
runoff for the Hotan, Yarkand and Aksu rivers imply that all 3 rivers are chaotic dynamical systems that are sensitive to initial conditions, and the dynamic modeling of their annual runoff processes requires at least 4 independent variables; 3) the time
Human impact on sediment dynamics - quantification and timing
Sediment dynamics. Special issue
This special issue provides a selection of papers (7/24) that were presented at the European Geosciences Union (EGU) General Assembly in Vienna (April 2007) in session GM19 on Quantifying and modelling human and climate controlled sediment dynamics
on the human impact on sediment dynamics, the methodologies used and the spatial and temporal scales considered.

New detailed data about the morphology of the submerged slopes of Lake Albano have been collected by a sonar multibeam survey. These data allow for investigation of the subaqueous slope dynamics of the lake, which partially fills a volcanic

, which in turn acts as a control on the dynamics of tidewater glaciers. Despite these numerous recent scientific advances, there remains a need to critically evaluate the importance of supercooling for the various aspects of sediment entrainment and flux
