This paper presents the sensitivity analysis results of feed forward multilayer perceptron based Artificial Neural Network model for water level prediction in a data constraint transnational Surma River of Bangladesh. Catchment characteristics, hydro-geomorphological, meteorological and headwater...

Extreme floods often demonstrate unanticipated characteristics that pose problems for management and response. The flood in the Stratoni region in February 2010 provided an example of such unexpected response. The aim of this paper is the quantification of the hydrologic response of the torrents...

In this paper soil conventional tillage (CT) in two adiacent on-farm sites, hilly and plain fields, was carried out in comparison with direct-seeding + fertilizing at very low water content. The quality and quantity of work were evaluated through machine performance, fossil-fuel energy requirements...

Crop irrigation, especially in irrigation networks, often consumes larger quantities of irrigation water than necessary since most of the times irrigation is carried out empirically and not based on actual crop requirements. The aim of this work is the management of irrigation water though the use...

In this paper, the application of a continuous rainfall-runoff model to the basin of Kosynthos River (district of Xanthi, Thrace, northeastern Greece), as well as the comparison of the computational runoff results with field discharge measurements are presented. The rainfall losses are estimated by...

Since a spectrum of hydrological and geomorphological conditions produce flood pulse environment in a riverine or a deltaic system, it is essential to have the knowledge on spatial and temporal distributions of river flow and dependent processes for environmental flow requirements, ecosystem...

Deep groundwater data reflects hydrological processes, climate change and variability, as well as any anthropogenic influence. Decomposition of deep groundwater signal examines the history of the groundwater region. Detrending is a vital step in decomposition of groundwater time series because it is...

The Alfeios River is the greatest in length and flow-rate river in Peloponnisos and constitutes an important water resource and ecosystem of Western Greece. A number of infrastructure works and human activities have been constructed and are operating in Alfeios River Basin, while in the past...

Irrigation water use is the major pressure limiting the availability of fresh water resources in the Mediterranean. Efficient irrigation scheduling programs (IRSPs) are able to reduce water consumption; however, their selection and placement in large agricultural landscapes depend on location...

This effort discusses and evaluates alternative water management options to alleviate water stress and meet water needs in insular entities of the Aegean Archipelago, within the framework set by the principles of Integrated Water Resources Management (IWRM) and of the Water Framework Directive 2000...

The estimation of evapotranspiration is essential in water resources management. Among a group of methods, the Penman–Monteith has been commonly applied to calculate reference evapotranspiration as this method has been also recommended by the Food and Agriculture Organization of the U.N. (FAO)...

In this paper the results of a preliminary study that investigates water footprint (WF) concept, as a useful tool to address water management problems in cultivated areas are presented. The two basic methodologies reported in the literature, their applicability, benefits and challenges were...

Commonly used analytical methods for assessing the effects of recharge and withdrawal on the groundwater flow system are based on an idealistic assumption that the aquifer’s base is fully impervious. In reality, the hydrostratigraphic conditions are often complex and involve leakage induced flow...

In Tunisian semi-arid regions, where water is a rare commodity and the large dams cannot be justified considering the very limited water contributions and the very high evapotranspiration, innovative techniques of harvesting water have been adopted. Tunisia has initiated a policy of small dam...

The coastal plain of Corinth, known also as Vocha plain is one of the fast-growing rural areas due to its relatively short distance from Athens. In conjunction with the fast development, water use has also increased. On a large part of the Plain area, irrigated agriculture is practiced and...

It is difficult for decision-makers to evaluate the impact of their territorial policies. Aspects to be considered in this evaluation include those relating to humans, environment protection and industry development. Two reasons explain the difficulty: decision-makers cannot specialise in all...

The political dimension of water becomes highly important not only because of its scarcity, but also as a result of its sharing across national boundaries. Approximately 40% of the global population lives in tranboundary water basins, emphasizing the need for cooperation and harmonization of...

The importance of the development and application of groundwater simulation mathematical models in the protection of aquifer systems is nowadays recognised as an undisputable fact. In this paper a mathematical model that was developed in order to simulate the operation of the Upper Anthemountas...

An environmental database has been created, recording water bodies at a national level and assembling relevant data collected by various public services and institutions in charge of water resources management and research in Greece. Data consists of physico-chemical parameters, geomorphological...

A prototype Spatial Decision Support System for the evaluation of water demand and supply management schemes is presented. The water basin is topologically mapped to a network of spatial objects representing the physical entities and their connections. Several GIS functions, which include data input...

The Peninsula of Sithonia is one of many typical regions in Greece in which overexploitation of local aquifers has led to several serious problems related to quantity and quality degradation of groundwater reserves. In this paper, a management plan is presented that aims at the utilization of the so...

The present attempt has a two prong-emphasis. On the one hand it demarcates the physical, structural, social and economic parameters and the eliciting environmental problems in Thriassion Plain, the main industrial area of metropolitan Athens, Greece. On the other hand it attempts to delineate a...

An initial GIS data base has been assembled in 2001 covering the various parameters related to the Nestos river basin and its delta. This data set is being used for water resources modelling purposes within the frame of the multinational PROMENES initiative. The initial data gathering has produced a...

The current study presents the development of a Forecasting Information System for geographic data (cross-sectional time-series for different geographic regions). GFIS, Geographic Forecasting Information System, was developed with MS Visual Basic (User Interface), ArcView (GIS) and MS Access (DBMS)...

A risk-based decision analysis methodology is presented, that can be used as a water policy tool in the design of economic incentive instruments, under conditions of uncertainty. A contaminated groundwater resource system with unknown hydrogeological parameters is used as a case study. The polluter...
