Major issues with respect to water management in Sirsa district are waterlogging and salinization in areas with saline groundwater and over-exploitation of groundwater in areas with fresh groundwater. The present crop yield increase of the major crops in Sirsa district is marginal. Recent studies show that water is the main limiting factor to incre...
Irrigation will be required to meet the demands of the world population for food. Water will also be needed to meet the municipal, industrial, and environmental demands of the growing population. As a result irrigation water supplies will be reduced and irrigators will probably be forced into using degraded water as part of the supply and the possi...
Due to unavoidable, prolonged irrigation with marginal quality water, secondary salinization of irrigated soils in Pakistan has necessitated to a need for better understanding of the water management alternatives. Although H2SO4 and gypsum have far been recognized for their benefits in treating brackish water but during field trials, their relative...
The characteristics of various sulfate-rich wastewaters, such as temperature, pH and salinity, are determined by the (industrial) process from which they originate, and can be far from the physiological optima of the sulfur cycle microorganisms. The main goal of the research described in this thesis was to investigate and develop high rate sulfate ...
Momenteel worden voorbereidingen getroffen voor de bouw van nieuwe spuisluizen in de Afsluitdijk. Deze nieuwe sluizen moeten het mogelijk maken dat het overtollige zoete water uit het IJsselmeer, ook bij de verwachte stijging van de zeespiegel en een toename van de aanvoer van rivierwater vanuit de ijssel, nog tenminste tot het jaar 2050 kan worden...
Most of Jordan is arid and water resources are limited. This situation becomes more acute the more Jordan develops. New techniques in agriculture, industry and the domestic sector place an increasing demand upon clean and safe water. Good-quality water is hardly available. Unconventional water sources, including treated sewagewater, must be conside...
UItleg over een nieuw ecologisch beoordelingssysteem voor brakke binnenwateren, aansluitend bij de al bestaande STOWA-beoordelingssystemen voor andere watertypen. Op grond van het ecologisch functioneren en een geformuleerd ecologisch streefbeeld worden beïnvloedingsfactoren, karakteristieken en maatstaven onderscheiden, waarmee voor verschillende ...
Keywords: anisotropy, aquifer, desalinization, effluent salinity, groundwater, irrigation, salt-water upconing, soil salinity, stream-function, subsurface drainageIrrigated agriculture in arid and semi-arid zones often suffers from waterlogging and salinity problems. Sub-surface drainage systems can be used to control the groundwater table and to f...
