Abstract This paper is a presentation of landslide monitoring, early warning and remediation methods recommended for the Polish Carpathians. Instrumentation included standard and automatic on-line measurements with the real-time transfer of data to an Internet web server. The research was funded through EU Innovative Economy Programme and also by the SOPO Landslide Counteraction Project. The landslides investigated were characterized by relatively low rates of the displacements. These ranged from a few millimetres to several centimetres per year. Colluviums of clayey flysch deposits were of a soil-rock type with a very high plasticity and moisture content. The instrumentation consisted of 23 standard inclinometers set to depths of 5-21 m. The starting point of monitoring measurements was in January 2006. These were performed every 1-2 months over the period of 8 years. The measurements taken detected displacements from several millimetres to 40 cm set at a depth of 1-17 m. The modern, on-line monitoring and early warning system was installed in May 2010. The system is the first of its kind in Poland and only one of several such real-time systems in the world. The installation was working with the Local Road Authority in Gorlice. It contained three automatic field stations for investigation of landslide parameters to depths of 12-16 m and weather station. In-place tilt transducers and innovative 3D continuous inclinometer systems with sensors located every 0.5 m were used. It has the possibility of measuring a much greater range of movements compared to standard systems. The conventional and real-time data obtained provided a better recognition of the triggering parameters and the control of geohazard stabilizations. The monitoring methods chosen supplemented by numerical modelling could lead to more reliable forecasting of such landslides and could thus provide better control and landslide remediation possibilities also to stabilization works which prevent landslides.

The ability to predict the imminent arrival of coastal storm risks is a valuable tool for civil protection agencies in order to prepare themselves and, if needs be, execute the appropriate hazard-reduction measures. In this study we present a prototype Early Warning System (EWS) for coastal storm risk on the Emilia-Romagna coastline in Northern Italy. This EWS is run by executing a chain of numerical models (SWAN, ROMS and XBeach) daily, with the final output transformed into a format suitable for decision making by end-users. The storm impact indicator selected for this site is the Safe Corridor Width (SCW), which is a measure of how much dry beach width is available for safe passage by beach users. A three-day time-series of the predicted SCW is generated daily by the prototype EWS. If the minimum SCW exceeds a certain threshold, a warning is issued to end-users via an automated email service. All available prediction information is also updated daily on-line. Over the one year that the EWS has been operating (June 2011 until June 2012), 13 “code red” and 16 “code orange” warnings have been issued, with the remaining 305 predictions indicating low hazard in terms of the SCW. The reliability of the predictions from the perspective of the end-user has meant that the EWS is currently being expanded to include the entire Emilia-Romagna coastline.

The implementation of an Early Warning System for storm impacts in the urban beach of Cadiz is presented. The model train is described in detail together with the downscaling procedure. Emphasis is given on how the morphodynamic model receives the necessary information from the regional operational oceanography system specifically developed for the Gulf of Cadiz. The translation of the morphodynamic model output into useful information for the civil protection and other responsible authorities is provided based on the coastal state indicator approach. All the intermediate and final results are presented in a purpose-based on-line application.

In building a new On-line Multi-factor Monitoring System (OMMS) of Water Accidental Pollution Events (WAPE) based on the behavioral responses (BR) of aquatic organisms, the effects of physi-chemical factors (PF) such as temperature (T), turbidity (TUB) and pH on BR of Daphnia magna and medaka (Oryzias latipes) were discussed with Biological Early Warning System (BEWS). The results suggested that when T was lower than 5°C, BR of D. magna and medaka would be inhibited in 5 hours. If TUB was more than 50NTU, the behavior strength (BS) of D. magna would decrease to about 0.3 after 10h exposure, the effects on medaka would be much weaker in 24h than D. magna. If pH is lower than 5.5 or higher than 9, negative effects on BR of both aquatic organisms would happen in 15h. Therefore, a new OMMS was built for the purpose of environmental management of WAPE, which included BEWS and PF Monitoring System (PFMS).
