    Beach-Profile Measurement, Theory and Analysis: Practical Guidance and Applied Case Studies (2000)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 14 (2000), S. 0 
    Details

    Notes: Whilst beach-profile surveying is a relatively long-established and widely utilised shoreline monitoring technique, a considerable gap exists between theoretical and practical requirements from, and uses of, beach-profile data. The paper bridges this gap by providing a summary of the key elements of beach-profile measurement, theory and analysis. The benefits of applying these elements to practical coastal management are given in three case studies. The first case study presents results from beach-profile analysis on a regional scale in East Anglia. The second case study applies both analytical and theoretical techniques to investigate erosional problems along a coastal bay in Jersey. The third case study assesses the performance of two major sand-replenishment schemes in Poole Bay (on the south coast of England) based upon beach-profile volumetric analyses. Most importantly, the paper demonstrates that beach-profile measurement, theory and analysis can provide information of practical use in coastal management.

    Habitat Creation Opportunities for Landward Coastal Re-alignment: Essex Case Studies (1998)

    Notes: Relative sea-level fluctuations during the Holocene period have combined with medieval to present saline floodplain embanking to reduce the inter-tidal saltmarsh area in Essex from 40 000 ha to 4400 ha. The present loss by erosion is estimated at 2%/annum for the country, and the reduction in these areas is not only detrimental to related habitats but has caused an increasing requirement for flood-defence financial investment.Recent initiatives by the Ministry of Agriculture, Fisheries and Food, the Environment Agency and English Nature have created mechanisms and opportunities to develop sustainable flood-control structures where coastal re-alignment has been the preferred option.The Orplands frontage covers 2 km of sea wall which have been deliberately breached to allow 40 ha of rare saltmarsh to re-establish. At Abbotts Hall, an arable field of 20 ha has been converted to its former saltmarsh by creek re-establishment and tidal inundation by reversal of existing sluices. These two schemes have (a) regenerated habitats for halophytic and semi-halophytic plants, marine and brackish invertebrates, and (b) provided roost, feed and breeding areas for birds and nursery areas for marine fish fry. Apart from flood control and habitat creation, particular features were incorporated to provide niche locations for targeted types of wildlife.

    The Sea-Defence Value of Salt Marshes: Field Evidence From North Norfolk (2001)

    Notes: Approaches to coastal management have focused increasingly on ‘soft’engineering methods such as beach/foreshore recharge or the managed realignment of coastal defences. In this context, the creation/maintenance of salt marshes is often seen as being of ecological and flood-defence importance. However, until recently, no field data of wave attenuation over Northern European salt marshes had been available; therefore the debate on the sea-defence value of salt marshes has remained highly speculative. This paper (a) reviews results from a field and numerical modelling study at Stiffkey, north Norfolk, (b) presents a scientifically based argument for the evaluation of salt marshes as part of sea-defence schemes, and (c) discusses the relationship between hydrodynamic parameters, salt-marsh surface characteristics, and possible management implications and engineering guidelines.

    Description / Table of Contents: Summary Flow-injection determination of chloramine-T, dichloramine-T, dibromamine-T, bromamine-T, chloramine-B, dichloramine-B, dibromamine-B, bromamine-B and dichloramine-N in solution, through a spectrophotometric procedure is described. A simplified flow-injection apparatus with a two-channel system is employed. The carrier streams are starch-KI mixture (0.5∶5.0%) and 1 M H2SO4 and are merged before injection of haloamine. A sampling frequency of 280h−1 has been achieved. The effect of reagent concentrations, flow parameters and interferents on the analysis has been investigated. Concentrations of haloamines were in the range of 1–60 ppm.
    Notes: Zusammenfassung Die spektralphotometrische FIA-Analyse folgender Verbindungen wird beschrieben: Chloramin-T, Dichloramin-T, Dibromamin-T, Bromamin-T, Chloramin-B, Dichloramin-B, Dibroamin-B, Bromamin-B und Dichloramin-N. Ein vereinfachtes 2-Kanal-FIA-Gerät wird benutzt. Trägerlösungen sind KI-Stärke (5.0∶0.5%) und 1 M Schwefelsäure, die vor der Injektion gemischt werden. Ein Probendurchsatz von 280h−1 wurde erreicht. Einflüsse von Reagenskonzentrationen, Fließparametern und Störsubstanzen wurden untersucht. Die untersuchten Konzentrationen lagen im Bereich von 1–60 ppm.

    A flow injection method for analysis of residual chlorine by the DPD procedure (1983)

    Description / Table of Contents: Summary A flow injection method for automating the DPD reaction with free Cl in water samples has been described. The carrier stream consists of a 1∶1 (v/v) mixture of N,N-diethyl-p-phenylene diamine (DPD) indicator and phosphate buffer. A sampling rate of 252 per hour has been obtained and the detection limit is 0.3 ppm. Substitution of DPD with N,N-p-dimethylaniline sulphate also appears to be satisfactory for Cl analysis. The effects of reagent concentrations, flow parameters and additions of anions, cations and organic haloamines on the peak height have been investigated. The ammonium-Cl reaction has been studied and potentialities of the flow technique for the analyses of chloramines have been explored.
    Notes: Zusammenfassung Ein automatisches Verfahren wird beschrieben, das auf der Reaktion von N,N-Diethyl-p-phenylendiamin (DPD) mit freiem Chlor in Wasserproben beruht. Der Trägerstrom besteht aus einem 1∶1-Gemisch von DPD-Reagens und Phosphatpuffer. Je Stunde können 252 Proben verarbeitet werden. Die Nachweisgrenze liegt bei 0,3 ppm. Ein Ersatz von DPD durch N,N-p-Dimethylanilinsulfat ist auch möglich. Der Einfluß der Reagenskonzentration, der Durchflußparameter sowie von zugesetzten Anionen, Kationen und organischen Halogenaminen wurde untersucht. Die Ammonium-Cl-Reaktion wurde ebenfalls untersucht und eine mögliche Anwendung auf die Bestimmung von Chloraminen erprobt.
