This research aims at throwing light on applications of biological rapid assessment tools in the monitoring of environmental quality in Runde River catchment with intensive commercial sugarcane production. Burdened with drudgery in wet laboratory techniques, biological sensors (biosensors) and sensors can integrate catchment data from rapid assessment techniques to networks or Internet of Things (IoT). This research examines the techniques presented by biosensors and sensors and provides the checkboxes for sustained catchment monitoring. With available recent evidence from surveys it turns out the Runde River may not be polluted but this may reflect the time the survey was undertaken and suggestions made for routine checks

Abstract Smith, C. J., Banks, A. C., and Papadopoulou, K.-N. 2007. Improving the quantitative estimation of trawling impacts from sidescan-sonar and underwater-video imagery. – ICES Journal of Marine Science, 64: 1692–1701. The techniques of sidescan sonar and towed, underwater-video sled were assessed as rapid-assessment methodologies for investigating trawl impacts on the substratum. Sidescan sonar is able to image a swathe of ∼200 m with a resolution of ∼20 cm at a speed of 2–3 knots, and marks of trawl doors could be observed. The towed video system imaged a swathe of 1–2 m with a resolution of 1–2 cm at a speed of ∼1 knot, and trawl-door marks, scrape marks, local bioturbation features, and fauna could be observed. Multiple tows using both methodologies were carried out in two areas in Heraklion Bay, Crete. One area, experimentally trawled, was 80–90 m deep and characterized by mixed, maerly sediments; the other was a commercial trawl lane ∼200 m deep characterized by silty-clay sediment. Descriptions of the types of trawling feature and impacts caused by trawling were made for both areas. Images were analysed from the commercial deeper trawling ground for area assessment. For sidescan-sonar records, direction of trawling and trawl-mark density by category were estimated at periodic intervals along the track. For video, categories for trawl-mark density and level of bioturbation were estimated, along with the density of the crinoid Leptometra phalangium. Using geo-referenced positioning for each data point, area maps were constructed for each of the parameters, and correlations were tested between the different datasets. The use of the assessment techniques (characteristics, data usage, mapping, complementarity) in relation to trawling-impact studies is discussed, as well as possibilities for the use of the resulting data for management.

Ecologically Sustainable

Many of Australia's river systems have been seriously degraded by inappropriate management of regulated flows. Other systems are facing threats from future water resources developments. There is a lack of information available to aid in allocation of environmental flows to rivers in order that they are managed in an ecologically sustainable manner. The Environmental Flows Initiative (EFI) is a major Australia-wide R&D program into environmental flows, funded through the Natural Heritage Trust (NHT), and administered by Environment Australia (EA). The program aims to identify environmental values, undertake targeted research to identify risks to river systems and flow requirements to sustain environmental values, to trial flow management options, and to evaluate these trials. The NHT relies on matching funding provided by the State and Territory authorities, and supports integrative approaches with emphasis on works on-the-ground where possible. While the EFI will close significant knowledge gaps, other gaps remain. Some of these relate to development and validation of rapid assessment techniques, understanding the importance of flow variability and how to define it, manipulation of flows to control alien species, developing a system of prioritising rivers for environmental flows, and enhancing flows with other catchment, channel and floodplain rehabilitation measures.

Two strong earthquakes hit the region of Van (Turkey) in 2012, generating major losses. A large part of the building stock was damaged causing the evacuation of the residents. A post-earthquake investigation team dispatched by the UNESCO through the IPRED platform, six month after the earthquakes, observed the damage state in some still standing buildings. Ten buildings having different structural characteristics were observed. Slight structural damage and severe non-structural damage were observed in three multi-storey apartment buildings, being evacuated at the time of the investigation. Despite the slight structural damage, two multi-storey reinforced concrete shear wall buildings were listed for demolition based on the results of the post-earthquake rapid assessment. These two buildings were recently built based on modern seismic design regulations. The design blueprints were available to the investigation team with the support of the local community of Van. Various rapid post-earthquake investigation techniques applied by the investigation team generated contradictory results. A comprehensive seismic assessment was carried out to retrodict the observed seismic damage. Various methods were applied starting from simple rapid assessment techniques to more elaborated structural analysis based on nonlinear dynamic procedure. In the latter case, strength and stiffness degrading hysteretic models were applied and the non-structural masonry walls were considered in the analytical model. This paper presents the results of these structural analyses in comparison with the observed damage on site. Conclusions regarding the suitability of the applied seismic assessment techniques to retrodict the damage level of the investigated structures are drawn. Some findings of the post-earthquake investigation team are presented as well.
