The paper presents improvement solutions for the ecological reconstruction of salt land according to the characteristicsof their natural conditions. Agroameliorative, agrobiological, agrochemical and hydroameliorative methods may beused. Effectiveness of ecological restoration increases by applying complex ameliorative works. The main role of suchan undreground drainage facility is to collect the salt-loaded, leaching water. Drain distance is calculated for nonpermanentflow conditions, establishing a distance L that allows the lowering grounwater level from its highesthydraulic load to its best value, ht, withing a given time length. The sewer canals should have a depth of min. 1.2 if theland is not equipped with underground drains, and between 1.5 and 1.6 if underground drainage exists.The distancebetween the antenna and the sewer canal should be about 200 m or the length of the watering installation. Verticaldrainage consists in the use of wells with a depth of 25 m, equipped with selected gravel filter (Ø 2-7 mm) and adecanter (1.5 m in length). |
