“…In previous work (Smith et al 1991) colour appeared to be having little influence on user perception mainly because, for most waters, colour was not readily discernible by respondents (i.e., the studied waters were shallow, of low brightness, or colours were of low saturation such that hue was indistinct). Many of the waters selected for the current study were optically deep (i.e., the bottom was not visible and therefore did not interfere with people's perception of the water itself), or bright, or colours were highly saturated.…”

“…It could be construed as a somewhat pointless exercise to manage a visual property of water which is poorly perceived by the general public. Smith et al (1991) showed that perception of the colour of natural waters was difficult for water users. This was because the waters were shallow near the banks where observations took place, and the substrate was visible and had a confounding effect on judgments.…”

“…Smith et al (1991) suggested that the concept of colour has little general meaning in clear, shallow waters which are low in colour saturation. However, we found that hue was reasonably well described for waters with a considerable concentration of suspended particles imparting a high brightness, where saturation was high (the humic-stained water of the Inangahua River), where there was a bright, spectrally neutral substrate, and when the water depth was sufficient to provide a suitable optical path length (i.e., where the bottom was not visible).…”

“…An examination of the reasons for the "No" responses to Questions 1 and 2 shows that at Hamilton Lake there were two main detractors to bathing, the presence of many ducks and their obvious faeces (see also Smith et al 1991) and the belief that the water was in some way polluted or unclean. (Hamilton Lake is believed by some respondents to be in some way artificial-it is not, although the outlet is now controlled-and perhaps this, too, has a bearing on its negative perception.)…”

In a study of human perception of the appearance (clarity and colour) of rivers and lakes for bathing and aesthetic water use, we have shown that: bankside observers can reasonably accurately assess colour (hue) in some circumstances; and that the phenomenon of perceptual set (seeing what is expected to be seen) may influence the visual perception of some waters. Further, perceived naturalness of a water seems to provide for a more positive response towards a water body than might otherwise be expected.

“…Además, no hay recipientes para tirar la basura, lo que significa un incumplimiento de la normatividad (SEMARNAT 2016). Estudios previos han mostrado que los usuarios consideran que la limpieza o contaminación en las playas está determinada por factores visuales (Dinius 1981, Smith et al 1991, Anfuso et al 2014 y en la playa El Cochórit, un rasgo físico destacable como es la arena (Pranzini y Vitale 2011), fue valorada con mala limpieza. Lo anterior sugiere una falta de interés por el cuidado ambiental de la playa, así como un desconocimiento de riesgos sanitarios a la salud pública, tanto por usuarios como por prestadores de servicios y autoridades municipales de Empalme.…”

Palabras clave: playas recreativas, manejo de playas, indicadores ambientales, percepción pública RESUMEN La evaluación de la aptitud recreativa de playas es un asunto clave para diseñar estrategias de manejo. El objetivo de este estudio fue evaluar la aptitud recreativa y proponer una estrategia de manejo en la playa El Cochórit, municipio de Empalme, Sonora. La aptitud recreativa de la playa se evaluó con base en la percepción de los usuarios y en indicadores biofísicos. El valor estimado de la aptitud recreativa de la playa, según la percepción de los usuarios fue de 0.71 (medio) y con base en los indicadores biofísicos fue de 0.47 (medio). La aptitud recreativa de la playa requiere ser mejorada con atención prioritaria en: (1) inversión en infraestructura y servicios, (2) mantenimiento de limpieza, (3) implementación de programas de educación ambiental y (4) monitoreo anual de la calidad sanitaria del agua y de la arena. La estrategia de gestión ambiental debe considerar incluir a la playa El Cochórit en el Programa Playas Limpias de la Comisión Nacional del Agua con el propósito de orientar esfuerzos hacia su certificación como "playa limpia".Key words: recreational beaches, management of beaches, environmental indicators, public perception ABSTRACTThe assessment of recreational beaches fitness is a key issue to design management strategies. The aim of this work was to evaluate the recreational fitness and propose a management strategy for the Beach El Cochórit, municipality of Empalme, Sonora. The recreational beach fitness was evaluated based on the perception of users, as well as biophysical indicators. The estimated value of recreational suitability of the beach perceived by users was 0.71 (average) and based on the biophysical indicators was Rev. Int. Contam. Ambie. 33

Rivers are revered worldwide for their ecologic, scenic, and recreational value. The capacity to communicate effectively among human groups with vested interest in rivers hinges on understanding the nature of human perceptions of water quality and the extent to which they vary intraculturally. Recognizing the intersection between measured water quality and the characteristics of rivers that influence human perceptions facilitates potential for better communication across disciplines and among stakeholders. We conducted interviews and a pile‐sort task with water quality experts and nonexperts. Our analysis suggested human evaluation of water quality is guided by culturally constructed criteria, regardless of respondent expertise, experience, or demographics. Cluster analysis results implied that measured physical and chemical parameters of rivers were directly related to the visible attributes used in human judgments. We suggest that, regardless of variability among individual stakeholders, observable characteristics may be the foundation for a common understanding of water quality in rivers.
