In this paper, a method of assessing the spatial variation of the soluteloads of different subcatchments is presented, using a catchment in the Tertiary Hills of Bavaria as an example.

Measurements of suspended and dissolved loads in this watershed suggest that deforestation and agricultural activities increase the rates of erosion by a factor of five to ten. - (DWG)
The aim of this paper is to quantify the load of organic carbon, nitrogen and phosphorus from 2 large catchment areas, the River Kitka and the River Oulanka, and the transport of the nutrients into Lake Paanajärvi, a deep oligotrophic lake in NW

Much of the short-term solute process research in the last 20 years has focused on hydrochemical behaviour. This can help with the identification of solute source area type, but not the actual location of the solutional loss. The location
and the spatial distribution of erosion are crucial to the identification of long-term landscape evolution. The way ahead lies in the fact that catchment budgeting and geochemical studies have been able to provide solute uptake rates. If these can be related
to soil type, it may be possible to characterize the location and spatial distribution of solutional erosion through terrain analysis and soil maps in a GIS.

The purpose of this paper is to estimate the influence of the land use and the water balance on the dissolved load budget in drainage basins on silicate rocks. The water balance in the Hohes Venn and the Rureifel areas is mainly influenced
by decreasing rainfall intensity from the Hohes Venn towards NE. Furthermore, different organic and anorganic soil properties influence the water balance in these areas. The investigation of stream load indicates regional differences of water chemistry
Fitting concentration and load rating curves with generalized linear models

Generalized linear models may be used as a systematic and flexible alternative to existing practices in fitting sediment or solute concentration and load rating curves. In particular, they offer a one-step solution to the common and ackward problem
that a bias correction is needed when estimating total loads. As generalized linear models return predictions directly on the original measured scale, there is no need for back-transformation or subsequent correction factors. Example analyses are given
for suspended sediment concentration for an upland stream in the Northern Pennines and for phosphorus load for the Illinois River.

of dissolved and solid load yields. The morphometric analysis of the catchment areas could provide no explanation of the various runoff patterns. In contrast, the type of the substrate as an time-invariantquantitybhas a corresponding significance for the runoff
Thermal perturbation and rainfall runoff have greater impact on seasonal soluteloads than physical disturbance of the active layer

The AA. measured total dissolved solute (TDS) concentrations and normalised seasonal TDS fluxes (kg mm-1) in a series of small headwater catchments in the Canadian High Arctic over 3 consecutive summers (2007–09) to examine the impact of thermal
perturbation (increased soil temperatures) and physical disturbance (active-layer detachment slides) on solute dynamics in permafrost catchments. The results show that the impact of the disturbance area on seasonal solute flux is limited by discharge
and hydrological connectivity of the disturbed areas, and that summer rainfall allows for enhanced export of solutes from catchments subject to physical disturbance. Hence, seasonal solute export in these permafrost catchments was more sensitive to thermal
On the basis of data concerning small catchments not polluted by municipal and industrial sewage the AA. calculated the solute yield from rural areas. Calculations were carried out in a simplified way, taking into consideration the mean solute
concentrations from data for the years 1976-1985, and mean discharges of river waters. For 20 selected larger catchments of the Vistula tributaries the AA. also calculated the total solute yield, i.e. including the sources of municipal and industrial wastewater
. The AA. attempted to analyse the balance of the solute yield. Results were considered in relation to regional differentiation.

This paper is an attempt to estimate the influence of minewater discharge from the hard coal mines of USCB on the shaping of the hydrochemical conditions of river waters, considering mostly salinity and the salt load removed from this area
in soluteload transport has been underestimated. However, the low discharge period is important in the transport of dissolved material and this is in marked contrast to its very minor role in the transport of suspended sediment and bed load.
