Remotely sensed estimation of annual cotton production under different environmental conditions in Central Greece
Domenikiotis, C.; Spiliotopoulos, M.; Tsiros, E.; Dalezios, N. R. (2005)This study proposes an innovative approach for investigating the accumulated meteorological effects on cotton during the growing season. The quantification of the weather effects is based on the application of the Bhalme ... -
Remotely-Sensed innovative approach for the cumulative meteorological effects on cotton production
Domenikiotis, C.; Spiliotopoulos, M.; Tsiros, E.; Dalezios, N. R. (2004)In this study an innovative approach for investigating the accumulated meteorological effects on cotton production during the growing season is presented. The quantification of the meteorological effects is based on the ... -
Response time of forested mountainous watersheds in humid regions
Loukas, A.; Dalezios, N. R. (2000)This study proposes an analytical method for the estimation of time lag for forested mountainous watersheds. The water flow in a watershed is separated and analyzed in two phases, the land or hillslope phase and the stream ... -
Risk identification of agricultural drought for sustainable Agroecosystems
Dalezios, N. R.; Blanta, A.; Spyropoulos, N. V.; Tarquis, A. M. (2014)Drought is considered as one of the major natural hazards with a significant impact on agriculture, environment, society and economy. Droughts affect sustainability of agriculture and may result in environmental degradation ... -
The role of agrometeorological and agrohydrological indices in the phenology of wheat in central Greece
Dalezios, N. R.; Loukas, A.; Bampzelis, D. (2002)In this study the relationship between several agrometeorological and agrohydrological indices related to temperature, humidity, precipitation and solar radiation as well as yield is examined. The agrometeorological and ... -
Severity-duration-frequency analysis of droughts and wet periods in Greece
Dalezios, N. R.; Loukas, A.; Vasiliades, L.; Liakopoulos, E. (2000)There is an escalation in the frequency and severity of extreme events due to a number of environmental and/or anthropogenic factors. Droughts and exceptionally wet periods are regional phenomena, which are considered as ... -
Spatial variability of reference evapotranspiration in Greece
Dalezios, N. R.; Loukas, A.; Bampzelis, D. (2002)Optimal interpolation using geostatistical techniques, such as kriging, can be used for contouring and mapping of regionalized variables. In this study spatial variability of reference evapotranspiration over Greece is ... -
Spatio-temporal precipitation modelling in rural watersheds
Dalezios, N. R.; Adamowski, K. (1995)The paper develops a three-stage iterative procedure for building a Space-Time Autoregressive Moving Average (STARMA) model of multiple precipitation series. The identified model is STMA (13). The emphasis is placed on the ... -
SPATIOTEMPORAL PRECIPITATION MODELING IN RURAL WATERSHEDS
Dalezios, N. R.; Adamowski, K. (1995)The natural variability of precipitation in agricultural regions both in time and space is modelled using extensions of Box & Jenkins (1976) methodology based on the ARMA procedure. This broad class of aggregate regional ... -
Sustainable production zoning for agroclimatic classification using GIS and remote sensing
Tsiros, E.; Domenikiotis, C.; Dalezios, N. R. (2009)Agriculture is a primary productivity sector which is highly dependent on environmental conditions. The agroclimatic potential of agricultural areas has to be assessed in order to achieve sustainable and efficient use of ... -
Universal kriging of hail impact energy in Greece
Dalezios, N. R.; Loukas, A.; Bampzelis, D. (2002)In this study the spatial variability of hail impact energy was examined using universal kriging. The hailstorm of June 26th, 1988 in northern Greece was used for the development of methodology and the hailstorm of June ... -
The use of NOAA/AVHRR satellite data for monitoring and assessment of forest fires and floods
Domenikiotis, C.; Loukas, A.; Dalezios, N. R. (2003)The increasing number of extreme natural phenomena, which are related to the climate variability and are mainly caused by anthropogenic factors, escalate the frequency and severity of natural disasters. Operational monitoring ... -
Water Balance of Forested Mountainous Watersheds using Satellite Derived Actual Evapotranspiration
Loukas, A.; Vasiliades, L.; Domenikiotis, C.; Dalezios, N. R. (2004)The use of actual evapotranspiration derived by satellite data at watershed scale in water balance modelling of forested mountainous watersheds is studied. Mean monthly maximum composites of the Normalized Difference ... -
"Weather-related hazards and risks in agriculture" Preface
Gobin, A.; Tarquis, A. M.; Dalezios, N. R. (2013)In many parts of the world, weather represents one of the major uncertainties affecting the performance and management of agricultural systems. Due to global climate change, the climatic variability and the occurrence of ...
