RESULTS OBTAINED IN DRAINAGE ARRANGEMENTS DESIGN BY USING DRAINSPACE APPLICATION PUBLISHEDRareş Hălbac-Cotoară-Zamfir
Romania’s territory presents numerous areas with humidity excess from different sources and which supposes a proper water management for a durable administration of these lands with the purpose of promoting a sustainable agriculture. An efficient agriculture, taking into consideration Romania’s climatic conditions, can be practiced only with the support of land reclamation and improvement systems which are presenting technical and economical characteristics. Manual methods are becoming less used because they present risks in computing different indicators, supposes high volumes of manual work and they are considering long periods of time in reaching the targets (systems design). The software, which are modelling the hydric relations and interactions from soil active layer, present efficiency because they are taking into consideration numerous elements involved in these processes. WaSim is a computer-based training package for the teaching and demonstration of issues involved in irrigation, drainage and salinity management. WaSim simulates the soil water salinity relationships in response to different management strategies and environmental scenarios. WaSim contains 3 complementary design modules to aid sub-surface pipe drain design. Each of the 3 modules, for drain spacing, pipe sizing for field drains, and for collector drains, can be used separately from WaSim. DrainSpace module includes both Steady State (Hooghoudt) and Unsteady State (Glover-Dumm) equations are included in this module for calculating subsurface pipe drain spacing.
