network and catchment geometry. They show that the width to length ratio of the catchment has a significant influence on the shape of the hypsometric curve, though little on the hypsometric integral. Experimental results for simulated landforms from
This paper uses the SIBERIA catchment evolution model to explore linkages between catchment process and hypsometry. The AA. show that not only does the hypsometry reflect landscape runoff and erosion process, but it is strongly dependent on channel

Transport of dissolved silica in Kawakami forested headwater catchment : implication for tracing flow pathway
The aim of this study is to gain a simply approach in tracing flowpath and chemical pathway in a forested headwater catchment, the Kawakami Experimental Basin (KEB) situated in Nagano Prefecture, central Japan.
Within this paper a standardized method to quantify sediment transport and runoff in natural rills is described. In order to achieve this, several rill experiments (RE) were accomplished in March 2007 in the Arnás catchment in the Spanish Pyrenees

Hydrological structure and erosion damage caused by concentrated flow in cultivated catchments
Experimental geomorphology and landscape ecosystem changes (proceedings memorial symposium Prof. Jan De Ploey)
This study analyses the between-catchment variability of rill volumes produced by concentrated flow erosion during winter in the northern part of the Paris Basin. The working hypotheses were that 1) runoff concentrates along channels determined
by topography or by agricultural practices; 2) rill length is a major component of rill volume variability on a catchment scale; 3) rill cross-sectional areas are controlled by the size of upslope runoff-contributing areas connected to the corresponding channels
. Catchment erosion rates were estimated by adding together the predicted rill volumes for each segment within the catchment.

of 2.0 mm over an experimentalcatchment relief of approximately 200 mm; this resolution is considerably better than that achievable by conventional manual photogrammetry.
Automated digital photogrammetry was used to produce digital elevation models of experimental model landscapes under controlled laboratory conditions as part of a series of rainfall erosion experiments looking at the evolution of landforms
in response to erosion. The method allowed the elevations of the experimental landscapes to be studied in great detail on a regular grid digital terrain map. Digital photogrammetry produced elevation data at a resolution of 6 mm with a standard deviation

A physics-based Integrated Hydrology Model (InHM) was employed to conduct both three- and two-dimensional (3D and 2D) hydrologic-response simulations for the small upland catchment known as C3, located within the H.J. Andrews Experimental Forest

The hydrological and geomorphological effects of an exceptional rainstorm event that occurred in the central Spanish Pyrenees during 19-21 October 2012 were studied in 5 experimentalcatchments under various land covers : 1) subhumid badlands; 2
rainstorms, at least at the spatial scale at which the phenomenon was studied (catchment sizes : 0.3-2.8 km2) and under dry catchment conditions. Five pulses of most intense rainfall were recorded. The forested catchment did not react to the 2 most intense
rainfall pulses. The abandoned farmland catchment had 2 small peak discharges at the beginning of the event. The badland catchment reacted immediately from the beginning of the rainstorm, yielding very high discharges accompanied by high suspended sediment
concentrations. The subalpine catchment showed a hydrograph mirroring the hyetograph, with brief but intense hydrological responses to increased precipitation, because of the marked gradients and the presence of bare rock in the headwaters. A high volume
