The goal of this study was to better understand how vegetative characteristics affect water quality in conveyance structures in the context of ditch class and surrounding land use.
These conveyance structures and surrounding buffer zones are being ranked for their ability to reduce excess nutrients, suspended solids, and pesticides associated with runoff.
The Lincoln County, Conservation, Recreation, and Development Act (LCCRDA) establishes corridors in Lincoln County for water conveyance structures and shows the general location of the proposedgroundwaterpipeline.Credit: Adrian Welsh.
Tidal-creek fragmentation represents one of the most widespread human-caused environmental impacts in nearshore waters of the Bahamas (e.g., over 80% of tidal creeks are fragmented on Andros Island; Layman et al. 2004) and is generally caused by roads constructed across tidal creeks without proper flow conveyance structures such as culverts or bridges (Fig. 1).
These road blockages often lack flow-conveyance structures, such as bridges or culverts, resulting in disruption of hydrologic connectivity.
Segovia aqueduct, byname El Puente (Spanish: "The Bridge"), water-conveyance structure built under the Roman emperor Trajan (reigned 98 117 ce) and still in use; it carries water 10 miles (16 km) from the Frío River to the city of Segovia, Spain.
California Aqueduct, in full Governor Edmund G. Brown California Aqueduct, principal water-conveyance structure of the California State Water Project, U.S. From the Sacramento River delta east of San Francisco, it runs south through the San Joaquin Valley and over the summit of the Tehachapi Mountains, a distance of 273 miles (440 km).
L. 104 132 substituted "any structure, conveyance, or other real or personal property" for "any building, structure or vessel, any machinery or building materials and supplies, military or naval stores, munitions of war or any structural aids or appliances for navigation or shipping".
Last January, a federal grand jury in Seattle charged Mr. Dahoumane with crossing a national boundary and conspiring among other things to "destroy or damage structures, conveyances or other real or personal property".
Indoor air pollution can be defined as chemical, physical, or biological contaminants in the breathable air inside a habitable structure or conveyance, including workplaces, schools, offices, homes, and vehicles (the indoor environment).
Aquifer depletion also causes land to subside -- as much as a foot per year in some locations in California -- causing damage to structures, surface water conveyance, utilities, and transportation infrastructure.
