The FAO Land and Water Division created AquaCrop [31], a crop growth model, to address food security and evaluate how the environment and management affect crop productivity. AquaCrop models how herbaceous crops respond in terms of yield to water and is especially well adapted to situations where...
By incorporating input from both scientific experts and water practitioners, the aim was to derive balanced criteria weights that reflect technical groundwater quality considerations as well as applied management needs. Responses were transported matrices, and the relative importance of the parameters for ...
The barriers for their full-scale application and the research needs for overcoming these barriers are also discussed. The potential impacts of nanomaterials on human health and ecosystem as well as any potential interference with treatment processes are beyond the scope of this review and thus will...
Adhesion means that water also sticks very well to other things, which is why it spreads out in a thin film on certain surfaces, like glass. When water comes into contact with these surfaces, the adhesive forces are stronger than the cohesive forces. Instead of sticking together in a ball,...
Operated from a support vessel or the shore, marine drones are usually connected to their base of operations via an umbilical tether that provides power, communications and data transfer. Tetherless ROVs are rare due to the fact that radio waves do not travel well through water. However, soluti...
It is well known that the resistance to water flow through soil increases rapidly as soil dries because of decreased cross section for flow and increased pathway tortuosity as the films of water decrease in thickness and discontinuities develop. Soil hydraulic conductivity may decrease by several orde...
Ten years ago, after digging a new well that was very high in mineral content, we purchased an iron filtration system and a chlorine injection system from Water Filters of America. They helped me figure out what I needed and both systems have worked flawlessly. ...
to be bishop of the city. The church at Kildare, to suit the necessities of the double monastery and to accommodate the laity, was divided by partitions into three distinct parts. One of these was reserved for the monks; one for the nuns; while a third compartment was intended to suit ...
and its importance for survival of mankind and human health, the properties of water and its role in foods as well as in food production, processing, preparation, and consumption. It emphasizes the need for re-balancing water resources and recognizing the needs and uses of water while valuing ...
The El Yunque National Forest covers 28000 acres, and much of it is protected as wilderness areas. Ray and I are always looking for new trails to hike and, of course, elusive waterfalls. We recently went to the south side of the rain forest in search of
