[CEST2019_00923] Monitoring and treatment of cyanobacterial contaminated surface waters in France and Cyprus
by Antoniou M.G., Brient L., Tsiarta N., Keliri E., Christofi M., Hadjiouraniou G., Sukenik A.

Over the past few decades eutrophication of surface water has increased worldwide because of different anthropological activities including land fertilization and sewage run-offs; in combination with climate change. Excessive amount of nutrients (phosphorus and nitrogen), is now detected in freshwater lakes, artificially made reservoirs, and streams. Cyanobacterial nuisance in surface waters is among the most current environmental issues as it causes socio-economical problems.

[CEST2019_00884] An Assessment of Soil Erosion Using Rusle Model: A Case Study from the Marmara Region
by Ezer A., Guven B.

The aim of the study is applying the Revised Universal Soil Loss Equation (RUSLE) with the help of remote sensing and geographic information system techniques to calculate soil loss and to map soil erosion of the Marmara Region of Turkey in the changing climate conditions between 1989 and 2017, and also to make future projection of soil erosion for the years between 2020 and 2049.

[CEST2019_00846] Fuzzy Relation Between The RDIst Index And The Water Table Of A Coastal Aquifer of Nestos Delta, Greece
by Papadopoulos Ch., Gkiougkıs I., Spiliotis M., Pliakas F., Papadopoulos B.

Drought is a complicated natural extreme event associated with the decline of water availability below the normal conditions of a hydrological system, both from a temporal and from a spatial point of view. This work aims to assess the drought impacts on groundwater fluctuation in a shallow coastal unconfined aquifer via fuzzy approach. Meteorological drought intensity is estimated by the Standardized Reconnaissance Drought Index (RDIst) based on precipitation (P) and potential evapotranspiration (PET).

[CEST2019_00827] Revision of the Scarcity State Indicator in the Spanish Drought Management Plans
by Palop-Donat C., Paredes-Arquiola J., Andreu J.

Droughts are one of the gravest natural threats currently existing in the world and their occurrence and intensity might be exacerbated due to Climate Change. Scarcity is defined as the period when demand does not accomplish the normal reliability levels due to poor water management. Water and drought management plans (DMP) prevent scarcity periods by anticipating to drought and adapting to limited water resources. DMP in Spain were updated in December 2018. Two types of indicators were included: The Prolonged Drought Indicator and the Scarcity State Indicator (SSI).

[CEST2019_00808] Water Salinization in Iran: Spatial Variation of Salinity in Groundwater Resources of North West (Urmia Lake)
by Mosaferi M., Shakerkhatibi M., Jahanimoghaddam H., Esmat Saatloo M.

This study presents the quality of drinking water in terms of salinity in the western margin of Urmia Saline Lake (USL), Iran. During the study a total of 121 samples from 116 wells and 5 springs were collected which constitute drinking water resources of 301 villages in the study area. Approximately more than 30% of the water resources were brackish or saline. The maximum EC is recorded at 3060 µs/cm, which is more than 2500 µs/cm recommended by the European Union. The minimum EC is 410 µs/cm with an average of 980± 495µs/cm.

[CEST2019_00729] Simulating nutrient loads in an intensively cultivated Mediterranean watershed under current and projected climate conditions
by Pisinaras V., Kamidis N., Koutrakis E.T., Hatzigiannnakis E.,Panagopoulos A.

On the global scale, agriculture constitutes the most significant non-point pollution source for surface water bodies, especially in terms of nitrogen and phosphorus. Located in northeastern Greece, Vistonis basin, in which agricultural activities are widely developed, constitutes the area that discharges into Vistonis estuarine system, which is very significant both from the environmental and economic perspective. SWAT model was used in order to quantify discharge, nitrogen and phosphorus loads for the period 2003-2014, after calibration and validation.

[CEST2019_00707] Investigation of Shoreline Morphometry of Kızılırmak Delta’s Lagoons Using Fractal Dimension and Shoreline Development Index
by Uyar A., Ozturk D.

In this study, shoreline morphometry of the Karaboğaz, Balık, Uzun, Cernek, Liman, Gıcı and Tatlı lagoons which are located in the Kızılırmak Delta, was investigated by using fractal dimension and shoreline development index.

[CEST2019_00525] Hydrological and hydraulic modelling for a severe flood event in Sperchios River Basin
by Bournas A., Feloni E., Bertsioy M., Baltas E.

A combined hydrological and hydraulic analysis is presented for an extreme flood event occurred on February 6, 2012 in Sperchios River Basin, located in Central Greece. This event caused the river’s overflow and, consequently, several damages to infrastructure and agricultural land. Sperchios River Basin is a case of ungauged basin and only rainfall measurements of fine temporal scale are available.

[CEST2019_00453] How to identify a representative subset of hydro-climatic simulations for impact modelling studies?
by Pechlivanidis I.G., Gupta H., Bosshard T.

Uncertainties in hydro-climatic projections are (in part) related to different components of the modeling chain. Although a combination of numerous projections (ensemble) would be needed to characterize the overall uncertainty, in practice a small set of scenario combinations are constructed to provide users with a subset that is manageable for decision-making. The approach is based on a framework, rooted in the information theoretic Maximum Information Minimum Redundancy (MIMR) concept, for identifying a representative subset from an available large ensemble of hydro-climatic projections.

[CEST2019_00380] Reliable in-Situ Sensing of Water Quality Parameters Using Low Cost Autonomous Analysers
by Donohoe A., Hazel C., McCluskey P., McCaul M., Diamond D.

A sensing platform for the in situ, real-time analysis of phosphate in natural waters has been realised using a combination of microfluidics, colorimetric reagent chemistries, low-cost LED-based optical detection and wireless communications. Prior to field deployment, the platform was tested in the laboratory where a total of 459 autonomous measurements were performed (153 each of low calibration standard, high calibration standard and sample).

[CEST2019_00073] From system concept to serious game: the SIM4NEXUS approach to policy-relevant nexus research
by Sušnik J., Masia S., Khoury M., Vamvakeridou-Lyroudia L., Brouwer F., Riegels N., Domingo X., Echeverria L., Evans B., Savić D.

There is growing interest in using serious games for a wide range of applications and in the water-energy-food/land-climate nexus, where interactions in one sector lead to impacts in other sectors. Much practice revolves around sectoral silos, with little consideration of wider impacts. Serious games could help erode these silos, fostering efforts towards holistic policy making, where impacts can be explored and assessed without real consequences.
