[CEST2019_00641] Evaluation of a new millifluidic device for the consistent determination of oil droplet biodegradation kinetics
by Kapellos G.E., Nagarajan M.B., Kalogerakis N., Doyle P.S.

Natural seeps and accidental releases of crude oil in the sea result in swarms of droplets that are carried away by underwater sea currents. The droplets may be created either at the sea surface during the breakup of an oil slick by sea waves, or at the seafloor during the extrusion of crude oil from natural cracks or broken wellheads. A high concentration of oil droplets in seawater disturbs the established ecosystem dynamics and poses a significant risk of toxic effects to fish and other marine animals.

[CEST2019_00544] Overrated Credence to the Outdated Sand Mining Legislations : A Hydrologically Challenged Measure
by Sasi V.

The recent floods in the 'God's own Paradise'(Kerala) reminds the Indian Sub-Continent as well as the Global spectators of not just heavy rainfall but also the 'hungry water effect' from deranged desiltation. Laws from the first decade of independence decide the commercial desiltation permits and procedures in most parts of the country with renewed guidelines.

[CEST2019_00510] An Agent Based Modelling tool exploring decision-making processes for flood risk management
by Koutiva I., Makropoulos C.

Cities at risk of extreme hydro-meteorological events need to be prepared to decrease the extent of the impacts. However, the majority usually reacts to the catastrophe, having failed to proactively prepare against extremes. This can be a result of both absent structural protection measures and problematic governance. While for the first, models exist that can simulate the effect, the effect of the latter is difficult to quantify.

[CEST2019_00491] The Intensity – Duration (I-D) curves towards to a spatially distributed flood early warning tool (F-EWT)
by Feloni E., Baltas E.

Attica region suffers from rainfall events of high intensity, inducing flash-floods and significant damages in the urbanized areas. This analysis concerns the determination of the maximum intensity-duration thresholds regarding flooding (F) or non-flooding (NF) regime, using the available precipitation records and the dataset of Fire Service operations in flooded properties for the period 2005-2016. Each event is classified as ‘F’ or ‘NF’ in case of flooded properties or not, respectively. As expected, ‘F’ events prevail for the higher rainfall intensities.

[CEST2019_00398] Water Sustainability: Evaluation of Alternative Water Supply Methods in Greek and European Islands
by Tsesmetzis G., Kondili E.M., Kaldellis J.K.

Water is a very valuable natural resource absolutely necessary for life. Lately water resources are facing high pressure from continuously increasing demand. Besides, various areas face water shortage due to decrease of precipitation, irrational use, losses and mainly very high rates of tourism, especially in areas with water shortage and/or very limited water availability. Various water supply methods are applied in different cases in order to satisfy water demand, such as dams, desalination units, reuse of wastewater treatment plants effluents and water transport.

[CEST2019_00362] Water security of rural water supply systems in super typhoon Haiyan affected areas
by Gomba F.

The rural water supply systems in the countryside necessitate sustainability and security assessment to ensure long-term and safe water supply to target beneficiaries. The study aimed to analyse the hidden threatening factors in water supply system along technical requirements. It also predicts the probability of incidents and security degree of the system. The rural water supply system in typhoon Haiyan affected areas was rehabilitated and constructed through national and international funds.

[CEST2019_00299] Dam break analysis using HEC-RAS techniques. Case study: Cal Alb dam (NE Romania)
by Urzică A., Huțanu E., Mihu-Pintilie A. ,Stoleriu C.C.

Along with the understanding of the importance of a water resource in the vicinity of a human settlement, human societies have begun to build weirs, dams or hydraulic structures to use more efficiently the natural resource. One of the most important works that can be done in the course of a river is the construction of dams for the formation of storage areas. The importance of storage areas is given by their extensive use, whether used for flood defense, pisciculture, water supply or recreation.

[CEST2019_00308] Exceptional flood events in the summer of 2018 in the Trebes-Negel Representative Basin (Romania)
by Paveluc L.E., Grozavu A., Cojoc G.M. , Hutanu E.

In the summer of 2018, the general unstable weather throughout the central and eastern parts of Romania has led to significant rainfall, sometimes exceeding 60 mm/day, and therefore to a massive runoff on the slopes that rapidly increased the flow on tributaries and the main course of the river Trebes from the Moldavian Subcarpathians. The majority of the hydrometric basin stations recorded exceedances of the caution levels, and the hydrometric station Bacau registered the maximum historical level (H= 348 cm).

[CEST2019_00293] The role of hydro-technical works in diminishing flooded areas. Case study: the June 1985 flood on the Miletin River
by Huțanu E., Urzică A., Paveluc L.E., Stoleriu C.C., Grozavu A.

Hydro-technical constructions are very important in diminishing flooded areas and associated damage in the event of a flood. The case study for the Miletin River in the Moldavian Plateau (Eastern Romania) focusses on the historical floods of June 1985. The floods recorded at the Miletin River hydrometric stations are: 106 m3/s for Nicolae Balcescu station and 204 m3/s for Şipote station. Our analysis involves a series of simulations of a flood flow constant using the hydrological data associated with the 1985 flood.

[CEST2019_00105] The role of catchment properties on the importance of initial hydrologic conditions for seasonal hydrological forecasting in alpine areas
by Stergiadi M., Avesani D., Righetti M., Borga M., Zaramella M.

A well-known approach to seasonal hydrological forecasting involves the use of ensembles as forcing to a hydrological model, based either on historical meteorological data (Ensemble Streamflow Prediction, ESP) or on forecasts produced by one or more dynamic climate models (multi-model approach). This work aims at investigating the role of initial hydrologic conditions (ICs) and seasonal climate forecast skill on the accuracy of seasonal hydrologic predictions in alpine regions, as a function of catchment properties.
