This paper describes a two stage sediment budgeting technique to estimate the total volume of metal contaminated sediment stored within the River Swale, UK. This operates by dividing the catchment, and likely sediment stores, into two physically
and geomorphologically distinct areas (tributaries and the trunk channel). The AA. use a combination of techniques to establish the volumes of metal contaminated sediment remaining within the River Swale. Firstly, using detailed field sampling and a geographical
information system (GIS), they estimate the volumes of sediment remaining within one formerly mined tributary (Gunnerside Beck) which is then extrapolated to represent the contaminant volumes on other tributaries of the River Swale. Secondly, combining fresh
field data with a range of existing data, volumes of contaminated sediment on the main stream of the River Swale are established. This two tier approach shows that significant volumes of contaminated sediment remain within the River Swale and it may take

This paper introduces the use of GPS drifters (termed GRiFTers) to measure surface flow velocities in a 400 m reach of the River Swale, UK. The technique shows great promise to provide new insights into flow patterns over long reaches of rivers

. Simulations for 4 U.K. basins (the Rivers Swale, Ure, Nidd and Wharfe) shows that catchment response, driven by climate and conditioned by land cover changes, is synchronous but varies in magnitude.

and the partial area-weighted average slope. The AS2 index is similar to the AS1 but uses the swale slope as the weighting factor. From studies made using different ephemeral gully erosion databases, it is shown that a high correlation consistently exists between

The neoclassical economic base multiplier

The spatial variability of swale soils results in part from the significant hydrologic variability of low-lying landscape positions. Depth profiles of chloride concentrations suggest that hydrologic variability systematically correlates

During the past 2 years (1982-1984) a new investigation program has been directed by Dr. G. De Moor (De Moor, 1985) in which sampling was restricted to the sand ridges and swales of the Flemish Banks area (Kwinte Bank, Buiten Ratel Bank, Oost Dyck
