Enclosed beaches along urban coastlines are frequent hot spots of fecal indicator bacteria (FIB) pollution. In this paper we present field measurements and modeling studies aimed at evaluating the impact of small storm drains on FIB pollution at enclosed beaches in Newport Bay, the second largest tidal embayment in Southern California. Our results suggest that small drains have a disproportiona...
Life in central Iran depends on the Zayandehrood river, making the preservation of its quality important. Salinization and pollution of the flow as a result of different organic and inorganic pollutants create serious threats to the environment and to the agricultural activities in the region. Although the role of the main drains discharged into the Zayandehrood in changing its quality is well ...
This study evaluated the use of Asaoka and hyperbolic methods to estimate ultimate settlement soft ground treated by vacuum preloading combined with prefabricated vertical drains. For this aim, a large-scale physical laboratory model was constructed. The reinforced-tempered glass box containing soil mass dimensions 2.0 × 1.0 1.2 m (length width depth). Physical models scale for same purpose are...
In this paper, a study was carried out in order to estimate settlements and consolidation rates under embankments constructed on Moroccan soft soils. Settlement measurements in several embankments in High Speed Railway project between two Moroccan cities, Tangier and Assilah, were analyzed. The objective of this study is to estimate settlement values and settlement rates, with sufficient prec...
Usually, vertical drains are widely used to improve land reclamation and construction of urban planning, transport road construction, agriculture. Vertical drainage systems that use pumped wells, open dug or tube wells. There calculation methods based on pumping curves the filtration equation hydraulic drainage. In proposed system, jet apparatus is in systems. Jet pumps designed such a way they...
