“…The source, as well as the volume of runoff, has also been shown to affect water temperature behaviour (e.g. Kobayashi et al, 1999;Langan et al, 2001;Brown and Hannah, 2007), and rivers affected by seasonal snow-and ice-melt runoff commonly exhibit hysteresis in the water-air temperature relationship (Webb and Nobilis, 1994;Mohseni et al, 1998.…”

“…For example, water temperature is sometimes used as an easily to measure tracer for water movement in the topsoil (e.g. Katsuyama et al 2005;Kobayashi et al 1999;Sidle et al 2000). This is based on the large heat capacity of water of about 4.18 J/ kg/K.…”

The rapid increase of catchment runoff after the onset of rainstorms and the associated short‐term changes of stream‐water solute concentration are still poorly understood. These factors are dependent on the flowpaths that the water follows to the stream, and the length of time from rainwater infiltration to discharge. To study these processes, different approaches are used. Hydrometric data on, for example, discharge, groundwater level, soil matrix potential and soil moisture data, have a high spatial and temporal resolution. In contrast, hydrochemical data for solutes, isotopes and temperature, are spatial and temporal integrals. This article provides an overview of the different approaches that are used to investigate stormflow runoff, and critically examines apparent and actual tautologies and inconsistencies in them. Some of the inconsistencies can be traced back to a failure of the basic assumptions, whereas others remain to challenge our understanding of the runoff generation process. Finally, suggestions for future avenues of research in this field are made.

“…If the relationship between geochemical tracers and EC is close during different stages of runoff, EC may be used as a tracer itself. Separation of runoff components by use of EC has been presented, e.g., by Nakamura (1971), Pilgrim et al (1979), Kobayashi (1986), Caine (1989), McDonnell et al (1991) and Kobayashi et al (1999).…”

“…Mean content of main cations of different sources of runoff and streamflow in two creeks of the Pleistocene moraine sediments of the Lainbach area (IV) For the application of EC as a tracer it is crucial to have knowledge of the chemical composition of runoff during low flow and storm flow. Duysings et al (1983), McDonnell et al (1991) and Kobayashi et al (1999) have emphasized the risk of obscure results using EC for runoff separation if concentration courses of dissolved ions are not clear. Therefore, the relationship of EC and dissolved ions of the different sources of runoff has been studied carefully (cf.…”

Runoff production processes in small alpine catchments within the unconsolidated Pleistocene sediments of the Lainbach area (Upper Bavaria)

Abstract:In the Lainbach catchment, unconsolidated Pleistocene moraine sediments are widely distributed. Because of the great natural risk of floods, together with extreme loads of sediments, investigations of runoff production processes have been conducted in this area. At hillslope scale three test sites with different states of soil development and vegetation cover were instrumented with V-shaped weirs, precipitation gauges and measurement devices for electrical conductivity (EC) of discharge water. The EC has been used as a geochemical tracer for hydrograph separation, since the statistical relationship between content of dissolved Ca 2C , Mg 2C cations and EC is highly significant for different stages of runoff. This method allows hydrograph separation at high temporal resolution for both the rising and falling limb of the hydrograph. The following results of the investigations can be resumed. If relief conditions are similar, the effectiveness of runoff production decreases with an increasing density of vegetation cover. The runoff delivery ratio decreases as well as the peaks of runoff. In contrast, concentration times of hillslope catchments are equal, even if vegetation cover is of great density and soils are well developed. As a reason for the short reaction times, different runoff production processes have been detected. On bare ground, infiltration excess overland flow intensified by surface sealing processes is the main source for quick runoff. On hillslopes well covered by vegetation, translatory flow processes indicated by soil water with high solute contents force a rapid runoff reaction only a few minutes after rainfall has begun. It is to be assumed that translatory flow is a runoff production process typical for hillslopes covered by vegetation in a steep alpine relief. By means of the areal distribution of the topographic index, concentration of runoff production on a small part of the catchment has been demonstrated for hillslopes densely covered by vegetation. The investigations have shown that there is a lack of studies on runoff production processes in steep alpine relief, as well as a deficit of methods to quantify hydraulic properties of coarse-grained soils with a wide grain size distribution.
