“…PCA has been used extensively for various applications related to water quality. As examples, Wunderlin et al (2001) used PCA for the evaluation of spatial and temporal variations in river water quality and Marengo et al (1995) to characterise water collected from a lagoon as a function of seasonality and sampling site and for the identification of significant discriminatory factors. Hamers et al (2003) employed PCA to study pesticide composition and toxic potency of the mix of pollutants in rainwater and Librando et al (1995), for the analysis of micropollutants in marine waters.…”

Urbanisation significantly impacts on water environments with increased runoff and the degradation of water quality. The management of quantity impacts are straight forward, but quality impacts are far more complex. Current approaches to safeguard water quality are largely ineffective and guided by entrenched misconceptions with a primary focus on 'end-of-pipe' solutions. The outcomes of a research study presented in the paper, which investigated relationships between water quality and six different land uses offer practical guidance in the planning of future urban developments. In terms of safeguarding water quality, high density residential development which results in a relatively smaller footprint would be the preferred option. The research study outcomes bring into question a number of fundamental concepts and misconceptions routinely accepted in stormwater quality management. The research findings confirmed the need to move beyond customary structural measures and identified the key role that urban planning can play in safeguarding urban water environments.Keywords: multivariate analysis, stormwater quality management, urban water quality, water quality impacts 3

“…4), 1-r Pearson distance was used. All data were initially standardized through z-score transformation (Marengo et al 1995), and then statistical and mathematical calculations were performed using version 8.0 of the Statistica software (StatSoft Inc., Cracow, Poland) and Microsoft Office Excel 2003 spreadsheet (Microsoft Corporation, Warsaw, Poland). For dendrograms shown in Fig.…”

“…Samples collected from one watercourse can be grouped into two-clean and polluted, or three-clean, highly and medium polluted clusters representing similar water properties (Brogueira and Cabeçadas 2006;Chang 2005;Kannel et al 2007;Reghunath et al 2002). Marengo et al (1995) mentions application of CA for samples from Lagoon of Venice collected from various sites and at different seasons of the year. In this instance, it was concluded that location of sampling point rather than a season of sample collection determines clustering of the results.…”

The paper presents water-quality evaluation based on an 8-year monitoring programme in the Gdansk Municipality region, on the Southern coast of the Baltic Sea. The studies were carried out from 2000 to 2007 by surface water analysis at 15 various sites within eight watercourses. Sampling sites included rather urbanized or developed lands, farming fields and nonpolluted city recreational areas such as parks and forests. Most of the watercourses were sampled monthly at two locations, one within the upper course of the watercourse and the other near its mouth. In all samples, eight parameters of water quality were determined: total suspended solids, dissolved oxygen, water temperature, oxygen saturation, 5-day biochemical oxygen demand, chemical oxygen demand, total phosphorus and total nitrogen concentration. Interpretation of the obtained results revealed that examination of those basic physicochemical parameters permits to discriminate initially watercourses with respect to level of water contamination. During the research, a large dataset was obtained and it was described by both basic statistical parameters and chemometric method of cluster analysis. The paper presents relations between analysed parameters and influence of land exploitation mode on water quality and describes variation of the results both in space and time.

“…La dependencia estacional de la composición de aniones inorgánicos del agua de la laguna de Venecia fue investigada por Marengo et al (1995) a lo largo del periodo junio-noviembre de 1993. Desafortunadamente en este periodo el clima se comportó de forma atípica en lo que concierne tanto en lluvias como en temperatura y los datos obtenidos para las variables consideradas no permitieron correlacionarlas directamente con la temporada.…”

“…El PCA se usa como un procedimiento matemático que transforma un conjunto de variables correlacionadas en un nuevo conjunto de variables no correlacionadas (las componentes principales) (Johnson, 1992). Esta técnica está siendo cada vez más popular en la modelación ecológica y ambiental (Marengo et al, 1995;Vega et al, 1998;Wunderlin et al, 2000;Petersen et al, 2001;Brodnjak-Vončina et al, 2002;Simeonov et al, 2002;Montes-Botella et al, 2003;Mendiguchía et al, 2004;Singh et al, 2004;De Carlo et al, 2004;Parinet et al, 2004;Çamdevýren et al, 2005;Singh et al, 2005;Giussani et al, 2006;Kowalkowski et al, 2006;Terrado et al, 2006;Castañé et al, 2006;Felipe-Sotelo, 2007;Terrado et al, 2007;Shrestha et al, 2007;Kannel et al, 2007).…”
