Hydrological and hydraulic research for re-equipping an irrigated plot with pressurized pipelines

Abstract

Considering these factors we have decided that the following basic data are necessary for modernizing an irrigation plot: the climate studies for the last three decades regarding monthly precipitations and potential evaporation; the current crop planning; pedological studies on hydro-physical characteristics of the soil; phytotechnology studies; hydrogeological studies on the variation of the groundwater level; the types and functional characteristics of the irrigation systems in use now and/or in the future for each pipeline on the plot. Based on the aforementioned studies, there has been a recalculation of the maximum monthly norms of water application for the provisions of 50% and 80% on the rotating crops – norms which are indispensable in determining the maximum watering (hydro)module and the average weighted watering hydromodule, hydraulic variables used to determine the sizing flows of the plot pipeline network.
