Of this sphere, 10 percent is used extracted for human water consumption , which narrows the sphere to a sphere that is km in diameter, and would project onto Montenegro . The world must face the fact that Croatia can hold four land equivalents of Montenegro, and water availability has reached crisis standards Figure 4.

In surface irrigation systems, the area to be covered with water is sloped away from the supply channel so that the water will flow over the entire area with the water moving both across the surface to be irrigated and filtering down to the root bases of the plants in the field. Among the variations of surface irrigation are the techniques of furrow irrigation, border strips, basins, and wild flooding. Furrow irrigation has the advantage of allowing the crops to be tended shortly after watering periods.
Surface irrigation is where water is applied and distributed over the soil surface by gravity. It is by far the most common form of irrigation throughout the world and has been practiced in many areas virtually unchanged for thousands of years. Surface irrigation is often referred to as flood irrigation, implying that the water distribution is uncontrolled and therefore, inherently inefficient.
Drip irrigation in sugarcane is a relatively new innovative technology that can conserve water, energy and increase profits. Thus, drip irrigation may help solve three of the most important problems of irrigated sugarcane - water scarcity, rising pumping energy costs and depressed farm profits. Surface Drip.
A filter strip is an area of grass or other permanent vegetation used to reduce sediment, organic particulates, nutrients, pesticides, and other contaminants from runoff and to maintain or improve water quality. Filter strips intercept undesirable contaminants from runoff before they enter a water body. They provide a buffer between contaminant source, such as crop fields and water bodies, such as streams and ponds.
The application method must ensure a uniform distribution of water along the cropped field as well as in the root zone of the crop with high application efficiency. The ratio of water stored in the root zone to that delivered to the field should be maximum. There should be minimum or no wastage of water either through surface run-off or deep percolation below the root zone of a crop. Several water application methods are practised to suit different soil types, water supply and its quantity, the topography of the land, crops to be irrigated and costs.
Asbestos-cement pipe was commonly used for buried pipelines. It combines strength with light weight and is immune to rust and corrosion. Ratio of the time for the water to reach the end of the field to the total set time for an irrigation set on a furrow irrigation system The ratio should be less than 0.
