1. Water quality and crop production improvement using a wetland-reservoir and drainage/subsurface irrigation system.

In a wetland-reservoir system, tile drainage water and surface runoff water from agricultural fields are routed into a wetland reservoir, rather than into open-ended streams and drainage ditches. The collected water is then recycled back through a controlled tile drainage-subsurface irrigation...

5. Maintaining environmental and productivity sustainability of a non-homogeneous furrow set in different agro-landscapes.

The aim of this paper is to evaluate the impact of distribution uniformity on environment and productivity under furrow irrigation in different agro-landscapes in France and Bulgaria and propose geographically oriented irrigation options. Unlike studies based on a single furrow observation, these...

6. Where indigenous water management practices overcome failures of structures: the Wadi Laba spate irrigation system in Eritrea.

The only source of irrigation water in the Wadi Laba (ephemeral stream) spate irrigation system is the flood, which is highly unpredictable in occurrence and amount. It frequently damages the brushwood and indigenous earthen structures, locally known as agims and musghas, making (re)construction...

7. Hydraulic performance evaluation of the Wadi Laba spate irrigation system in Eritrea.

Spate irrigation is a method of harvesting and managing floodwater, which is unpredictable in timing and volume. In the spate-irrigated area of 16 000 ha in Eritrea, the farmers have for decades used brushwood and earthen diversion and distribution structures, locally known as Agims and Musghas, to ...
