    Bilinear surface smoothing is an alternative concept which provides flexible means for spatial interpolation. Interpolation is accomplished by means of fitting a bilinear surface into a regression model with known break points and adjustable smoothing terms. Additionally, as an option, the incorporation in an objective manner, of the influence of an explanatory variable available at a considerable denser dataset is possible. The parameters involved in each case (with or without an explanatory variable) are determined by a nonparametric approach based on the generalized cross-validation (GCV) methodology. A convenient search technique of the smoothing parameters was achieved by transforming them in terms of tension parameters, with values restricted in the interval [0, 1). The mathematical framework, the computational implementation and details concerning both versions of the methodology, as well as practical aspects of their application are presented and discussed. In a companion paper, examples using both synthesized and real world (hydrological) data are presented to illustrate the methodology. The proposed mathematical framework constitutes a simple alternative to existing spatial interpolation methodologies.

Fotia, «Evaluation of various sensors for irrigation management in urban landscapes,» in IrriMed 2015 – Modern technologies, strategies and tools for sustainable irrigation management and governance in Mediterranean agriculture, 2015.
    [BibTeX] [Abstract] [Download PDF]

    In many urban areas, landscape irrigation accounts for 50{\%} or more of the total water use. Control technologies are available for reducing over-irrigation and include special features such as multiple programs and start times, rain delay and water budget. A variety of sensors can be connected to modern controllers in order to provide useful data and improve irrigation efficiency: rain sensors can suspend irrigation for a certain period after rain, soil moisture sensors allow irrigation only when soil moisture is bellow a pre-set threshold, pyranometers allow controllers to monitor solar radiation as a measure of evapotranspiration and continuously adjust the frequency of irrigation events, while evapotranspiration based controllers (ET controllers) use a series of meteorological data to calculate the actual ET at the site and use it to adjust irrigation. In this framework a field study was conducted at the Technological Educational Institute of Epirus (Arta, Greece) during the irrigation period (May-September) of 2014. The purpose was to investigate the water conservation potential of various scheduling approaches of controllers with and without the use of special sensors. Five treatments: a) irrigation controller using water budget periods (reference treatment); b) irrigation controller using water budget periods + rain sensor; c) irrigation controller using solar energy (as measured by a pyranometer) integration for continuous calculation of frequency; d) irrigation controller connected to soil moisture sensor and e) irrigation controller connected to Evapotranspiration (ET) + rain sensor were applied to tall fescue, a cool-season turfgrass, which is considered the most commonly used in North and Western Greece. The evaluation was based on applied water quantity measurements; fresh and dry cuttings weight and solar radiation reflectance (PRI and NDVI indices). The results indicated that the ET, Soil moisture and Solar Radiation sensors saved 35-40{\%} of water when compared to a typical theoretically calculated constant irrigation schedule. The considerable savings for ET and Solar Radiation sensor treatments were not accompanied by any decline in growth or quality of the turfgrass. Soil Moisture sensor treatment showed no difference regarding growth and just a small difference regarding leaf area index when compared to the reference treatment. The conclusion is that the use of such sensors is strongly recommended as it is expected to lead to considerable water savings.

    Evapotranspiration is a key hydrometeorological process and its estimation is important in many fields of hydrological and agricultural sciences. Simplified estimation proves very useful in absence of a complete data set. In this respect, a parametric model based on simplification of the Penman–Monteith formulation is presented. The basic idea of the parametric model is the replacement of some of the variables and con- stants that are used in the standard Penman–Monteith model by regionally varying parameters, which are estimated through calibration. The model is implemented in various climates on monthly time step (USA, Germany, Spain) and compared on the same basis with four radiation-based methods (Jensen– Haise, McGuiness and Bordne, Hargreaves and Oudin) and two temperature-based (Thornthwaite and Blaney–Criddle). The methodology yields very good results with high efficiency indexes, outperforming the other models. Finally, a spatial analysis including the correlation of parameters with latitude and ele- vation together with their regionalization through three common spatial interpolation techniques along with a recent approach (Bilinear Surface Smoothing), is performed. Also, the model is validated against Penman–Monteith estimates in eleven stations of the well-known CIMIS network. The total framework which includes the development, the implementation, the comparison and the mapping of parameters illustrates a new parsimonious and high efficiency methodology in the assessment of potential evapo- transpiration field.

    Agriculture plays a key role in the management of water use. Especially in Greece, irrigation is an essential element of agricultural production and agricultural water use has a substantial share in total water use. The presented study illustrates the key features of the IRMA{_}SYSTEM, a regional, user-friendly computer/mobile-based, open and free modular software for estimating site specific crop water requirements and irrigation scheduling at multiple scales, from farm to water basin level. The estimation of irrigation water requirements and irrigation scheduling is based on a modification of the FAO 56 approach. The system takes into account historical and forecast agrometeorological data, along with crop and soil-water data to accomplish its tasks. Also, it is fully customizable, allowing the users to add site and crop specific information taking advantage of additional data. Feedback and evaluation procedures are already applied and expected to contribute to the improvement of the system.

    Abstract Broken line smoothing is a simple technique for smoothing a broken line fit to observational data and provides flexible means for interpolation. Here an extension of this technique is proposed, which can be utilized to perform various interpolation tasks, by incorporating, in an objective manner, an explanatory variable available at a considerably denser dataset than the initial main variable. The technique incorporates smoothing terms with adjustable weights, defined by means of the angles formed by the consecutive segments of two broken lines. The mathematical framework and details of the method as well as practical aspects of its application are presented and discussed. Also, examples using both synthesized and real world (soil water dynamics and hydrological) data are presented to explore and illustrate the methodology.

    Potential evapotranspiration (PET) is key input in water resources, agricultural and environmental modelling. For many decades, several approaches have been proposed for the consistent estimation of PET at several time scales of interest. The most recognized is the Penman-Monteith formula, which is yet difficult to apply, since it requires simultaneous measurements of four meteorological variables (temperature, sunshine duration, humidity, wind velocity). For this reason, simplified approaches prove very useful in absence of a complete data set and are strongly preferred. In the present study, we implement a recent parametric formula to model PET in the Arta plain, located in the Region of Epirus – Greece, which is based on a simplified formulation of the original Penman-Monteith expression and requires only mean hourly, daily or monthly temperature data, depending on the desired time step. The methodology is generic, yet parsimonious in terms of the input data, with its parameters adjusted through calibration, to the available PET data. A spatial analysis concerning the regionalization of the parameters and the comparison of PET estimates between the Penman-Monteith formula and the proposed methodology by implementing interpolation techniques is performed. The results are very satisfactory, illustrating that the proposed framework is efficient and constitutes a reliable alternative in the assessment of potential evapotranspiration field.

    According to EU Water Framework Directive 2000/60/EC, action is needed to protect waters in both qualitative and quantitative terms. In this context a challenge of water-related issues for Mediterranean countries is to integrate water demand management in agriculture and to develop added value tools to optimize efficiency in irrigation. Potential for a -40{\%} to -60 changes in water availability for irrigation in extended Mediterranean areas of EU countries in the near future make the necessity for optimum irrigation water managements a top priority goal especially in countries like Greece where irrigation consists the major water resources consumer (70{\%} according to FAO-AQUASTAT). This study presents the key features of IRMA{_}SYS (http://arta.irrigation-management.eu/), a regional, user-friendly computer / smart phone-based, open and free modular software for estimating site specific crop water requirements and irrigation scheduling. The estimation of irrigation water requirements and irrigation scheduling is based on a modification of the FAO paper 56 approach, combining hourly and daily time steps. The system takes into account both historical and forecasted agrometeorological data, along with crop and soil-water data to accomplish its tasks. Also, it is fully customizable, allowing the users to add site and crop specific information taking advantage of additional data. Feedback and evaluation procedures are already applied and expected to contribute to the improvement of the system.

    The purpose of this study is to describe an application that analyzes all the possible tasks a farmer makes in the field, from ploughing the soil, fertilization and use of herbicides, up to traceability of the agriculture products. Farmers are provided with smart phones and tablets for documenting their tasks and products in real time, so that they can use the Integrated Management System in an optimal way, ensuring practical, financial and environmental benefits. The agricultural products will be documented safely and stored in a central information point for future traceability. These documentations may follow the product till the consumer so that he has all the production information available. To achieve these goals a mobile information system is developed that includes amongst others decision support capabilities for the farmer. The system also offers mobile services so as to support the implementation of a whole network of producing units.
