Integrated modeling of hydrological processes through openmi and web services
Kokkinos, K.; Loukas, A.; Samaras, N.; Iatrellis, O. (2011)Difficulty in linking data and models across organizations is one of the barriers to be overcome in developing integrated decision-making systems since not all models exist in the same location. OpenMI is a popular standard ... -
Integration of a Hydrological Model within a Geographical Information System: Application to a Forest Watershed
Fotakis, D.; Sidiropoulos, E.; Loukas, A. (2014)Watershed simulation software used for operational purposes must possess both dependability of results and flexibility in parameter selection and testing. The UBC watershed model (UBCWM) contains a wide spectrum of parameters ... -
Inter-comparison of statistical downscaling methods for projection of extreme precipitation in Europe
Sunyer, M. A.; Hundecha, Y.; Lawrence, D.; Madsen, H.; Willems, P.; Martinkova, M.; Vormoor, K.; Bürger, G.; Hanel, M.; Kriaučiuniene, J.; Loukas, A.; Osuch, M.; Yücel, I. (2015)Information on extreme precipitation for future climate is needed to assess the changes in the frequency and intensity of flooding. The primary source of information in climate change impact studies is climate model ... -

Spiliotopoulos, M.; Loukas, A.; Mylopoulos, N.; Toulios, L.; Stancalie, G. (2014)The objective of this work is the investigation of the specific relationships between actual evapotranspiration based crop coefficients and vegetation indices adapted to Karla Watershed, central Greece. Surface Energy ... -
The migration of the UTHBAL hydrologic model into OpenMI
Loukas, A.; Kokkinos, K.; Vasiliades, L.; Liakopoulos, A. (2008)This paper deals with the implementation and the migration into OpenMI of a monthly conceptual hydrological model, called UTHBAL. The model has been developed by Loukas et al. [2003, 2007] and now is implemented under the ... -
A modeling system for the evaluation of water resources management strategies in thessaly, greece
Loukas, A.; Mylopoulos, N.; Vasiliades, L. (2007)A modeling system was developed to evaluate the sustainability of water resources management strategies in the two major basins of Thessaly Region in Greece, namely the Pinios River and the Lake Karla basins. The intense ... -
Multi-Criteria Analysis Framework for Potential Flood Prone Areas Mapping
Papaioannou, G.; Vasiliades, L.; Loukas, A. (2015)A fundamental component of the European natural disaster management policy is the detection of potential flood-prone areas, which is directly connected to the European Directive (2007/60). This study presents a framework ... -
A new remote sensing procedure for the estimation of crop water requirements
Spiliotopoulos, M.; Loukas, A.; Mylopoulos, N. (2015)The objective of this work is the development of a new approach for the estimation of water requirements for the most important crops located at Karla Watershed, central Greece. Satellite-based energy balance for mapping ... -
Nonstationary Frequency Analysis of Annual Maximum Rainfall Using Climate Covariates
Vasiliades, L.; Galiatsatou, P.; Loukas, A. (2015)The perception that hydrometeorological processes are non stationary on timescales that are applicable to extreme value analysis is recently well documented due to natural climate variability or human intervention. In this ... -
Optimal Management of an Overexploited Aquifer under Climate Change: The Lake Karla Case
Sidiropoulos, P.; Mylopoulos, N.; Loukas, A. (2013)This paper presents a study for finding the optimal management plan of an overexploited aquifer under global climate change. The study area is the aquifer of the basin of Lake Karla, located in the eastern part of Thessaly ... -
