Session 21 - Hydrology and water resources management

[CEST2019_00459] Flood Risk Management: past and future
by Venables J.

Based on her long involvement in water and sustainability – flood risk management, water and wastewater engineering, and water resources – Jean Venables will initially review how engineers and society have tried to deal with water in the environment. She will address recent developments in approaches such as catchment management, and integration of approaches for dealing with potable water supply, droughts and flooding. It is also important to consider how to both mitigate and adapt to climate change and its predicted effects.

[CEST2019_00327] Innovative sensors for crowdsourced river measurements collection
by Krommyda M., Tsiakos V., Rigos A., Tsertou A., Amditis A., Georgiou H., Jonoski A., Popescu I., Assumpcao T.

Flood risk prediction requires consistent and accurate sensor measurements, usually provided from traditional in-situ environmental monitoring systems. Crowd-sourced data can complement these official data sources, allowing authorities to improve and fill gaps in the hazard assessment process. However, collecting this information from volunteers, with no technical knowledge and while using low-cost equipment such their smartphones and tablets, raises the question of quality and consistency.

[CEST2019_00298] Trends in hydrologic prediction for the design of hydraulic projects
by Daniil E.I., Michas S.N.

Determination of runoff and related design discharges under past and future conditions are key elements for the design of flood defense, watercourse demarcation, urban stormwater, road drainage systems. Prediction is difficult and involves high uncertainty, especially for ungaged water¬sheds. Advanced computer capabilities provided by GIS and hydrologic modeling software facilitate computations and allow for the comparison of results by different approaches. Still many empirical relations are included, based on limited field data developed decades ago.

[CEST2019_00237] Climate change impact on river assimilative capacity: a case study application of water related climatic indicators
by Romas E., Ziogas A., Pechlivanidis I., Tzimas A.

In this investigation, we use climatic, water-related indicators to evaluate the impact of climate change on the assimilative capacity of the Asopos River, Central Greece. Indicators were developed and organised under the SWICCA climate service (http://swicca.eu), which aims to develop and showcase a Water Management Information Service for the Copernicus Climate Change Service based, among others, on real case studies and end-users.

[CEST2019_00188] Comparative Study of Flow through Vegetation Stems With and Without Foliage
by Mavrommatis A.,Christodoulou G.C.

The presence of vegetation in rivers, streams and riparian zones affects significantly the flow field and consequently the resistance, pollutant dispersion, sediment transport and ecological habitat. In this paper, a comparative study is undertaken to investigate the effect of an array of simple rigid or compound semi-flexible elements, resembling submerged small plants, on key features of the flow field. Measurements were taken by means of a 3-D ADV instrument at selected locations within the vegetation array and downstream of it.
