Most citrus and avocado water-use studies have been conducted in inland orchards; however, orchards located in coastal areas are subject to cooler temperatures and foggier atmospheric conditions. To develop coastal area crop coefficients (Kc values) for irrigation management, we measured orchard consumptive water use (ETc) from two different commercial orchards located near Ventura. In addition...

INTRODUCTION Saltwater intrusion and salinisation have contributed to drinking water scarcity in many coastal regions globally, leading to dependence on alternative sources for water supply. In southwest coastal Bangladesh, communities have few options but to drink brackish groundwater which has been associated with high blood pressure among the adult population, and pre-eclampsia and gestation...

Much of the protected habitat available to the threatened Marbled Murrelet Brachyramphus marmoratus and other old-growth associated species in the Pacific Northwest is in narrow strips along the coast (e.g., parks and scenic fringes). Using data over two years from three watersheds on southwest Vancouver Island, we show that such shoreline strip forests represent suboptimal habitat for murrelet...

Herein we report on the abundance and composition of floating marine debris (FMD) in coastal waters of the SE-Pacific (off the Chilean coast) during the austral summer 2002. The observed FMD consisted mainly of plastic material (86.9%). Densities of FMD were highest between 20 degrees S and 40 degrees S, corresponding to the main concentrations of human population and activities. Low densities ...

Prehistoric environmental change in Hawai'i is evaluated through the analysis of sedi-ment and pollen samples from dated cores and excavation profiles in the coastal low-lands of O'ahu. It is suggested that a lowland Pritchardia palm forest and associatedspecies underwent rapid decline starting between about A.D. 1000 to 1200. This de-cline seems to have occurred earlier in coas...

The mainly fresh water arboviral vector Aedes aegypti L. (Diptera: Culicidae) can also undergo pre-imaginal development in brackish water of up to 15 ppt (parts per thousand) salt in coastal areas. We investigated differences in salinity tolerance, egg laying preference, egg hatching and larval development times and resistance to common insecticides in Ae. aegypti collected from brackish and fr...

The fore-arc region of northeast Japan is an area of extensive seismic activity and tsunami generation. On July 13, 869 a tsunami triggered by a large-scale earthquake invaded its coastal zones, causing extensive deposition of well-sorted fine sand over the coastal plains of Sendai and S ma. Sediment analysis and hydrodynamic simulation indicate that the tsunami inferred to be triggered by a ma...

The site under study covers an area of 273 km in the Oristano plain on the west coast of Sardinia (Italy). Since 1950 the plain, formed during the Quaternary by alluvial deposits, has been under intensive cultivation and is an important dairy farming centre. In the coastal region, the large number of wells (25,000 tapped and not) some very close to each other, has resulted in over-exploitation ...

Elevated concentrations of arsenic, up to 161 μg/L, have been identified in groundwater samples from the confined basal aquifer underlying the aquitard of the Pearl River Delta (PRD). Both aquatic arsenic in pore water and solid arsenic in the sediments in the basal aquifer and aquitard were identified. Arsenic speciation of groundwater in the basal aquifer was elucidated on a pH-Eh diagram. In...

With the increasing tendency of natural hazards, the typhoon/hurricane/tropical cyclone induced surge, wave, precipitation and river flood as extreme external loads not only menace Nuclear Power Plants (NPP) in coastal areas, but also some inland territorial NPP. For all of planned, designed and constructed NPP the National Nuclear Safety Administration of China and International Atomic Energy ...
