HERVIS GRANDA, Guillermo et al. Planning of water resources needed in the first irrigation of rice. riha [online]. 2018, vol.39, n.1, pp. 3-16. ISSN 1680-0338.

Detailed planning of water resources needed for the first irrigation of rice is a pending subject in the updating process of irrigation systems for this crop. To answer this need, the present work introduces a methodology based on the integration of a procedure for irrigation design in rice terraces along with a geographic information system (GIS). Parameters for water resources planning are obtained from algebraic operations between maps and the detailed quantification and resources needed for each field. Its application to a group of rice fields allowed to obtain necessary water volumes and discharges for the first irrigation of rice and, from these, to evaluate functionality of the existing irrigation system.

Palabras clave : zone scale application; hydraulic design; geographic information system.
