Assessment of NDVI and agrometeorological indices for major crops in central Greece
Dalezios, N. R.; Loukas, A.; Bampzelis, D. (2002)Major agricultural crops such as vineyards and apples can be monitored by comparing normalized difference vegetation index (NDVI) with several agrometeorological indices. The agrometeorological indices used in this study ... -
Basin-wide actual evapotranspiration estimation using NOAA/AVHRR satellite data
Loukas, A.; Vasiliades, L.; Domenikiotis, C.; Dalezios, N. R. (2005)The present study elaborates on the estimation of actual evapotranspiration at watershed scale using mathematical models and remote sensing techniques. A water balance model was updated and used to simulate runoff from a ... -
Climate change effects on drought severity
Loukas, A.; Vasiliades, L.; Tzabiras, J. (2008)This paper evaluates climate change effects on drought severity in the region of Thessaly, Greece. The Standardized Precipitation Index (SPI) has been used for estimation of drought severity. A geographical information ... -
Climate change implications on flood response of a mountainous watershed
Loukas, A.; Vasiliades, L.; Dalezios, N. R. (2004)The modification of the flood response due to future climate change is presented for the Illecillewaet watershed of British Columbia, Canada. The Canadian Centre for Climate Modeling Analysis General Circulation Model ... -
Climatic impacts on the runoff generation processes in British Columbia, Canada
Loukas, A.; Vasiliades, L.; Dalezios, N. R. (2002)The potential impact of future climate change on runoff generation processes in two southern British Columbia catchments was explored using the Canadian Centre for Climate Modelling Analysis General Circulation Model ... -
A collaborative approach to enviromental modeling
Kokkinos, K.; Samaras, N.; Loukas, A.; Mylopoulos, N. (2014)Integrated Environmental Modeling Systems, (IEMS) are multidisciplinary systems which focus on complex environmental problems, decisions and policies. They are characterized by formulating dynamic and interdependent ... -
Cotton yield estimation based on NOAA/AVHRR produced NDVI
Dalezios, N. R.; Domenikiotis, C.; Loukas, A.; Tzortzios, S. T.; Kalaitzidis, C. (2001)The high temporal resolution of the NOAA/AVHRR satellite data can provide an efficient and consistent way for biomass and yield monitoring and assessment. The reflected radiation provides an indication of the type and ... -
Development of a district information system for water management planning and strategic decision making
Loukas, A.; Tzabiras, J.; Spiliotopoulos, M.; Kokkinos, K.; Fafoutis, C.; Mylopoulos, N. (2015)The overall objective of this work is the development of a District Information System (DIS) which could be used by stakeholders for the purposes of a district day-to-day water management as well as for planning and strategic ... -
Ecosystem simulation modeling of nitrogen dynamics in the restored lake Karla in Greece
Laspidou, C.; Kakoulidis, I.; Loukas, A. (2011)Restored lakes are complex dynamic ecosystems. Ecosystem-level modeling of the processes that take place in a lake is a useful tool for understanding lake function and structure and for making predictions. A nitrogen ... -
The effect of climate change on floods in British Columbia
Loukas, A.; Quick, M. C. (1999)A hydrological modelling of the flood response of two watersheds to climate change are presented. The two study watersheds are the Upper Campbell and the Illecillewaet watersheds located in British Columbia. The first ... -
