Underground irrigation is provided by the WaterMaster product line that includes sprinkler timers, valves, accessories, tools and sprinkler heads. The DripMaster line is designed for delicate drip-water applications in areas with special needs (e.g., gardens, flower beds, container plants, trees and ground cover).
Even in the computer era, manual watershed delineation is still a useful skill, in order to check whether watersheds generated with software are correct. [1] Instructions for manual watershed delineation can be found in some textbooks in geography or environmental management, in government pamphlets, [4] [5] or in online video tutorials. [6]
A freshwater lake developed in the basin about 400,000 – 500,000 years ago near the Calico Archaeological Site. The lake was present until the late Pleistocene. The last high stand of Lake Manix was at 543 m (1,781 ft) and had a surface area of approximately 236 km 2 (91 sq mi). This lake drained, probably catastrophically, approximately ...
Recently completed infiltration basin for stormwater collection. An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
This basin type differs from a retention basin, also known as a "wet pond," which includes a permanent pool of water. [ 7 ] [ 8 ] [ 9 ] While basic detention ponds are typically designed to empty within 6 to 12 hours after a storm, extended detention (ED) dry basins improve the basic detention design by lengthening the storage time, for example ...
The term height of land is used in Canada and the United States to refer to a drainage divide. [2] It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". [3] In glaciated areas it often refers to a low point on a divide where it is possible to portage a canoe from one river system to ...
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
It formerly was the Mojave River's terminal lake, [5] and received about 1 millimetre per year (0.039 in/year) of sediment. [45] The Coyote Basin was not permanently coupled to the main lake body; its relatively large surface area and consequently high evaporation would have stabilized lake levels when it was connected to Lake Manix proper.
