“…The excess sediment affects the water chemistry, aquatic organisms, and the water clarity in our streams and reservoirs. Excess sediment is aesthetically displeasing, increases the cost of treating drinking water, decreases water clarity, and has an overall negative impact on the aquatic ecosystem [4][5][6][7][8]. The increased turbidity not only affects the water aesthetics but also reduces photosynthesis and organisms' visibility.…”

Excessive sediment is a major pollutant to surface waters worldwide. In some watersheds, streambanks are a significant source of this sediment, leading to the expenditure of billions of dollars in stabilization projects. Although costly streambank stabilization projects have been implemented worldwide, long-term monitoring to quantify their success is lacking. There is a critical need to document the long-term success of streambank restoration projects. The objectives of this research were to (1) quantify streambank retreat before and after the stabilization of 18 streambanks on the Cedar River in North Central Nebraska, USA; (2) assess the impact of a large flood event; and (3) determine the most cost-efficient stabilization practice. The stabilized streambanks included jetties (10), rock-toe protection (1), slope reduction/gravel bank (1), a retaining wall (1), rock vanes (2), and tree revetments (3). Streambank retreat and accumulation were quantified using aerial images from 1993 to 2016. Though streambank retreat has been significant throughout the study period, a breached dam in 2010 caused major flooding and streambank erosion on the Cedar River. This large-scale flood enabled us to quantify the effect of one extreme event and evaluate the effectiveness of the stabilized streambanks. With a 70% success rate, jetties were the most cost-efficient practice and yielded the most deposition. If minimal risk is unacceptable, a more costly yet immobile practice such as a gravel bank or retaining wall is recommended.

“…Factors such as water quality, clarity, and color influence viewers' assessments of the amenity or aesthetic value of these water landscapes [7]- [18]. Furthermore, Ryan [18], Pfluger et al [19], and Vesterinen et al [20] have shown that water clarity is an important determinant of public perception of water quality. A water surface with a good visual quality can attract more tourists [1] [21] and the visual satisfaction of people observing a water body is thus very important.…”

“…Water quality is one of the main factors that affect users' perceptions of the coastline environment [7] [15]; it is influenced by several parameters, including water temperature, chlorophyll content, turbidity, color, total phosphorus (TP), nitrogen, Escherichia coli (E. coli), and oil content [7] [15] [19] [22]. Given that several of these physico-chemical water parameter variables are independent, there is a need for a comprehensive water quality index that incorporates multiple measures of water quality.…”

Visual satisfaction of the tourists with a water body is strongly influenced by water clarity, which is in turn influenced by a number of water quality parameters. Visual satisfaction thus stands to benefit from having a water quality management tool that results in better water clarity. A Clarity Suitability Index of Water Quality (CSIWQ), derived from clarity suitability curves of selected water quality parameters, can allow estimation of optimal values for these parameters, while ensuring high visual satisfaction among tourists. The present study used sampling and survey methodologies to investigate water clarity and quality at five tourism fishing ports; simultaneously, tourists' visual satisfaction with a water body was assessed through a questionnaire based on their perceptions. The relationship between tourists' visual satisfaction and water clarity was found to be positive and strong, with water clarity having predictive power of 74.2%. The study showed that DO, BOD, TP, and SS were the most critical parameters for water clarity. A continued product approach of CSIWQ was found to be most appropriate for describing the relationship between water clarity and these four parameters. This enabled a CSIWQ Index value to be calculated. With a CSIWQ value of 0.6, water clarity would be more than 2.08 m, and tourists would experience very high satisfaction. CSI curves showed that DO would preferably be 9.0 mg/L, and BOD, TP, and SS less than 0.5 mg/L, 0.12 mg/L, and 45.0 mg/L, respectively. The model thus produced valuable insights for assessing and improving water quality and ensuring high levels of visual satisfaction among tourists in tourism fishing ports. This model identified only four parameters but could be improved by ensuring that other water quality parameters were included, to encourage an increase in the number of tourists and to include monitoring of more pollutant sources.

“…Aesthetic quality of surface waters is mainly related to public visual perception based on the clearness of water. Pflüger et al (2010) demonstrated that the public had the lowest preference for rivers where turbidity and SSC are high. Similarly, the relationship between degraded aesthetic quality of surface waters and suspended sediment or turbidity has been reported in the literature (Effler et al 1992;Smith et al 1995;Bernal et al 1999;Bilotta and Brazier 2008).…”

Surface water bodies can be impaired by turbidity and excessive sediment loading due to urban development, construction activities, and agricultural practices. Turbidity has been considered as a proxy for evaluating water quality, aquatic habitat, and aesthetic impairments in surface waters. The US Environment Protection Agency (USEPA) has listed turbidity and sediment as major pollutants for construction site effluent. Recently proposed USEPA regulations for construction site runoff led to increased interest in methods to predict turbidity in runoff based on parameters that are more commonly predicted in runoff-erosion models. In this study, a turbidity prediction methodology that can be easily incorporated into existing runoff-erosion models has been developed using fractions of sand, silt, and clay plus suspended sediment concentration of eight parent soils from locations in Oklahoma and South Carolina, USA.
