sugarcane, which has high water requirements, is grown in khuzestan province (iran). climate and optimizing the use of water is very important to sustainable cultivation of sugarcane. studies of water requirements for sugar cane in khuzestan show that in parts of sugarcane agro-industry, the water applied is more than the actual water requirement of the plant. the present study was conducted to...

The drainage of particulate foams is studied under conditions where the particles are not trapped individually by constrictions of the interstitial pore space. The drainage velocity decreases continuously as the particle volume fraction φ(p) increases. The suspensions jam--and therefore drainage stops--for values φ*(p) which reveal a strong effect of the particle size. In accounting for the par...

due to the important role of subsurface drainage in managing the ground water level, there are many researches focused on finding a new and more economic way to develop subsurface drainage technologies. lack of proper drainage system in northern iran has caused huge implantation of rice and it is impossible to have second implantation in this region. one reason of insufficiency of current drain...

Abstract. Hydrological systems of glaciers have a direct impact on the glacier dynamics. Since 1950s, geophysical studies provided insights into these hydrological systems. Unfortunately, such were predominantly conducted using 2D acquisitions along few profiles, thus failing to provide spatially unaliased 3D images englacial and subglacial water pathways. The latter has likely resulted in flaw...

[1] Electric field bursts were passively observed when a nonwetting fluid displaced a wetting fluid in a porous material (drainage) as well as during imbibition experiments. A sandbox experiment was conducted to study these electrical disturbances using a network of very sensitive nonpolarizing electrodes located at the top surface of the tank. Drainage exhibited many more electrical bursts, wi...
