<Para ID="Par1">Water Scarcity encompasses both permanent and occasional water resources shortages. Measures to combat water scarcity are of different nature dependent on whether they intend to withstand permanent or occasional water deficiency. It is the aim of this paper to discuss and propose a systematic...</para>

<Para ID="Par1">The definition of the relationship between the actual flow delivered by a node of a water distribution network and the available nodal pressure head is one of most crucial problems in Pressure Driven Analysis (PDA). The paper proposes a procedure, based on two models (building model and supplied...</para>

<Para ID="Par1">Groundwater economic models have refined optimal extraction rules while lagging behind in the study of optimal spatial policies. This paper develops a theoretical model to estimate welfare gains from optimal groundwater management when the choice variable set is expanded to include well location...</para>

Half-hourly ground-based GPS measurements of precipitable water vapor (PWV) from January 2009 to December 2012 are analyzed to investigate their potential for hydrological applications at basin level. In particular, the usefulness of these high temporal resolution data for monitoring extreme...

<Para ID="Par1">Although water scarcity is a well-understood concept, it is difficult to define it precisely and furthermore, to address the water scarcity which requires a complicated set of water actions. In this work, with the aim to face the complexity of water scarcity, we propose the establishment of...</para>

A biased coinflip Ansatz provides a stochastic regional scale land surface climate model of minimum complexity, which represents physical and stochastic properties of an ideal rainfall–runoff chain. The solution yields the empirically derived Schreiber formula as an Arrhenius-type equation of...

Regional drought modes in Portugal are identified applying the Principal Component Analysis (PCA) and Varimax rotation to the Standardized Precipitation Index (SPI) computed on various time scales using the three precipitation datasets covering the period 1950–2003: (i) The observation dataset...

<Para ID="Par1">As the need for energy is increasing, the challenges in the future are to operate existing large hydraulic schemes in more sustainable ways and to develop future water resources projects that are able to achieve a better balance between environmental and socio-economic demands. In this context,...</para>

<Para ID="Par1">The authors propose a measurement method that divides the depth of the soil sample in discrete regions to investigate soil water propagation dynamics using soil impedance measurements. Experiments were conducted on a cylindrical phantom using a clay loam soil sample (60 % clay, 21 % loam and...</para>
