Automated water sampling in ephemeral hydrological systems

This paper presents two approaches to using a data logger to interface between a flow recorder and a sampler, and provides a framework for the collection of high quality data from the field. Two hydrological systems were monitored; both

A digital surface roughness meter

by a single operator and can be used in the laboratory or field.

Ring permeametry : design, operation and error analysis

This paper describes an alternative ex situ core permeametry technique that is field based. The potential sources of precision and bias error within the method are quantified and their effect on the uncertainty of permeability estimates

Seabed stress determinations using the inertial dissipation method and the turbulent kinetic energy method

Direct measurements of seabed stress are difficult, especially in field conditions. Several methods for estimating these stresses using current meter data are available. Two of these methods, the Inertial Dissipation Method and the Turbulent Kinetic

CDW photogrammetry of low relief fluvial features : accuracy and implications for reach-scale sediment budgeting

). Guidelines are provided on field technique designed to minimize errors in the mapping of a terrain surface and to determine the necessary minimum target density for a given level of accuracy. The technique may then be incorporated into a revised methodology

Global positioning system: an effective way to map a small area or catchment

an existing control network, and the gathering of topographic data from a difficult field site. Two examples are given, one in East Texas, demonstrating the speed and accuracy of different techniques, and the other in the Quantock Hills in Somerset.

Problems associated with quantitative magnetic sourcing of sediments of the Scarborough to Mablethorpe coast, northeast England, U.K.

of northeast England, using rapid field and laboratory magnetic techniques. The methodology employed involves classification and modelling of sediment sources and mixtures based on their magnetic properties. This paper represents results obtained during a short
