Integrated Approach for Innovative Monitoring Strategies of Reservoirs and Lakes

Abstract

An innovative strategy significantly increasing data density by introducing a flexible, problem-orientated, and cost-effective water quality monitoring approach is presented. Most current monitoring strategies produce water quality data based on fixed stations conducted on fixed dates throughout a defined period of time and, thus, often give a biased and insufficient picture of the water quality. Establishing a refined picture of water quality while not increasing monitoring costs clearly needs a change in monitoring strategy. The complexity of social-economic needs, environmental aspects and evolving legislative guideline values makes the design of a suitable innovative strategy challenging. The combination of investigative and risk-based monitoring with real-time monitoring of proxies (e. g., electrical conductivity (EC)) is a vital asset within this here proposed innovative strategy. For the former, organic micropollutants (e. g., pesticides, pharmaceuticals) are suggested in this article to be a powerful tool for source apportionment as they allow to determine and quantify the cause and impact of water quality impairments. This strategy was tested in a field campaign in which an area of elevated EC was investigated at Lake Garda, Italy. A radio-controlled boat was used for EC mapping and sampling. As no chemical indicators for significant anthropogenic sources could be detected, the elevated EC could be assigned to natural sources.

From the Perspective of Jurisprudence View the Application of Urban Image Monitoring Technology and the Application and Improvement of the Information Collection System in This Field

“…Urban image surveillance implemented under a standardized system can effectively improve social management capabilities and help establish a standardized and orderly social order. e installation of monitoring equipment in public places may cause conflicts between the security interests of the monitor or the public interests of the society and the privacy interests of the monitored person [28,29]. In general, video surveillance in public places and other public areas can effectively establish social order, which is beneficial to the overall progress of society and the interests of the vast majority of people.…”

Combined sewer overflows: A critical review on best practice and innovative solutions to mitigate impacts on environment and human health

“…It used an innovative and smart series of gates that automatically adjusted themselves in order to optimize the storage capacity of a sewer system during rainfall events. Moreover, in the INTCATCH project, as an innovative approach to monitor water quality, autonomous and radio controlled boats are developed and demonstrated in key catchments such as Lake Garda, Lake Yliki (Warner, Nödler, Farinelli, Blum, & Licha, 2018). The results revealed that monitoring the routine parameters can give an overview of the current status of the water body, as well as contribute to reducing the monitoring cost.…”

“…The results revealed that monitoring the routine parameters can give an overview of the current status of the water body, as well as contribute to reducing the monitoring cost. Moreover, real-time monitoring of site-specific indicator allows determining the pollutant source which helps to derive proper catchment management strategy (Warner et al, 2018). The applications of smart data infrastructure systems can be optimized by two different methods.…”

Occurrence and Fate of Emerging Pollutants in Water Environment and Options for Their Removal

“…Pharmaceutical compounds (entailing different classes: hormones, anti-inflammatory, anti-epileptic, statins, antidepressants, beta-blockers, antibiotics, contrast agents, etc. ), after administration are largely excreted in the original form or as metabolites and can be found in urban wastewater, hospital sewers and surface waters [2,[30][31][32]. They can also reach groundwater or even drinking water, as well as the soil from irrigation water.…”
