Huarmey River
The Huarmey River in Peru is a seasonal river, with flows in the months of December to March; along with the underground water it is a vital source for the agricultural activities, industrial and domestic in the region. The delta is an important agricultural area while the irrigation water in this arid zone is derived from the Huarmey river. Without irrigation by river water agriculture would not be possible. However, the natural underground drainage of the area is limited, and for this reason the lower parts of the delta have become waterlogged and salinized.Ground Water International, 2008. ''Huarmey drainage project, conceptual phase.'' On line/ref> To overcome this problem, the installation of wells to abstract groundwater for supplemental irrigation and lowering of the water table, and drainage by ditches and wells to evacuate the salty percolation water, is being implemented.

Ancash Region
Ancash ( qu, Anqash; es, Áncash ) is a department and region in northern Peru. It is bordered by the departments of La Libertad on the north, Huánuco and Pasco on the east, Lima on the south, and the Pacific Ocean on the west. Its capital is the city of Huaraz, and its largest city and port is Chimbote. The name of the region originates from the Quechua word ('light, of little weight'), from ('blue') or from ('eagle'). Geography Ancash is a land of contrasts: it features two great longitudinal valleys, which combine the mountain characteristics of the Callejón de Huaylas (Alley of Huaylas) with the sylvan ones of the Alto Marañón. Kilometres of sandy beaches and the blue waters of the Pacific. The territory of the coast, high plateaux and Andean '' punas'' of the department are flat, while the rest of the territory, in the Andes, is very rough. In the west, there are slopes with strong declivity form narrow canyons with abrupt and deserted sides. The rough territor ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Arid-zone Agriculture
Dryland farming and dry farming encompass specific agricultural techniques for the non-irrigated cultivation of crops. Dryland farming is associated with drylands, areas characterized by a cool wet season (which charges the soil with virtually all the moisture that the crops will receive prior to harvest) followed by a warm dry season. They are also associated with arid conditions, areas prone to drought and those having scarce water resources. Process Dryland farming has evolved as a set of techniques and management practices used by farmers to continually adapt to the presence or lack of moisture in a given crop cycle. In marginal regions, a farmer should be financially able to survive occasional crop failures, perhaps for several years in succession. Survival as a dryland farmer requires careful husbandry of the moisture available for the crop and aggressive management of expenses to minimize losses in poor years. Dryland farming involves the constant assessing of the am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Water Table
The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. The groundwater may be from precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths, water fills in more of the pore spaces in the soils, until a zone of saturation is reached. Below the water table, in the phreatic zone (zone of saturation), layers of permeable rock that yield groundwater are called aquifers. In less permeable soils, such as ...

Percolation
Percolation (from Latin ''percolare'', "to filter" or "trickle through"), in physics, chemistry and materials science, refers to the movement and filtering of fluids through porous materials. It is described by Darcy's law. Broader applications have since been developed that cover connectivity of many systems modeled as lattices or graphs, analogous to connectivity of lattice components in the filtration problem that modulates capacity for percolation. Background During the last decades, percolation theory, the mathematical study of percolation, has brought new understanding and techniques to a broad range of topics in physics, materials science, complex networks, epidemiology, and other fields. For example, in geology, percolation refers to filtration of water through soil and permeable rocks. The water flows to recharge the groundwater in the water table and aquifers. In places where infiltration basins or septic drain fields are planned to dispose of substantial amounts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huarmey Delta
''For the Province of the Ancash Region in Peru, see Huarmey Province'' Huarmey is a coastal town in the Ancash Region, Peru. It is one of the five districts and also the capital of the Province of Huarmey. It is located crossing the Pan-American highway from south to north after leaving the department of Lima in Paramonga and at 82 km from the Fortaleza River. It was created by law 24034 on December 20, 1984. At certain times of the year, the settlers fish abundant shrimps in the Huarmey River. This river fertilizes the valley and flows from south to north. The port of Huarmey is located at 5 km to the south, through a detour that begins in the Pan-American highway. Huarmey is 83 km from the next major city, Casma. This city is largely undeveloped, though is one of the main cities of the Ancash Region. Huarmey has its own beaches and it has facilities for camping and surf. The water is very cold all year round, despite the high temperatures of the city. Huar ...
