Special Issue Information
Dear Colleagues,
The calculation of irrigation requirements is done by simulating the soil water balance, considering rainfall, runoff, drainage, capillary rise, the soil reservoir, and the evapotranspiration components. All these factors with greater or less simplification are considered in the simulation models. The size of the reservoir depends on the soil characteristics and the root system of the crops. Based on vegetation indices calculated by remote sensing, knowledge of the phenological phases of crops as well as the crop coefficients can be significantly improved. Rainfall and crop evapotranspiration depend on the climatic characteristics of the region under study, and they are the variables that have greater spatial variability. Computer tools that spatialize those variables improve the calculation of irrigation requirements, and they are decisive to improve the water use.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
