Potential Role for the Vetiver System in Gulf Coast
Potential Role for the Vetiver System in Gulf Coast

... Vetiver grass has a massive, finely structured root system that is unique among grasses. With no rhizomes or stolons that spread to the sides, the plant’s roots grow straight down as a mass as dense as the amount of leaves it produces above the ground. These roots penetrate 3 to 4 meters into the so ...

SahysMod



SahysMod is a computer program for the prediction of the salinity of soil moisture, groundwater and drainage water, the depth of the watertable, and the drain discharge in irrigated agricultural lands, using different hydrogeologic and aquifer conditions, varying water management options, including the use of ground water for irrigation, and several crop rotation schedules, whereby the spatial variations are accounted for through a network of polygons.
