The lowering of the groundwater table causes the area above the water table to become unsaturated and capillary phenomena to appear in this zone. This means that the bearing capacity of shallow footings will be influenced by capillary stress or matric suction. In this research, the effect of groundwater table lowering on the bearing capacity of a shallow square model footing on dense sand has b...

The coastal, unconfined aquifer at Huntington Beach, California contains saline groundwater (33 psu) adjacent to the water line, and a brackish groundwater (BGW) mixing zone (3–9 psu) approximately 50m from the water line. According to salinity and water isotope analyses, the BGW composition varies spatially in the alongshore direction. Measurements obtained from two BGW wells indicate this wat...

Various researchers have reported and described the adverse effects of saltwater ingression in coastal zones of different parts of world like Italy, Japan, Greek islands, Oman, Nigeria, Atlanta Coast USA, Turkey, Netherlands, Catalonia and Sardinia and various coastal areas of India [1-35]. India has long coastal line of 5700 km. The east coast (Coromandel Coast) extended from West Bengal to Ka...

A watershed's riparian corridor presents opportunities to stabilize streambanks, intercept runoff, and influence shallow groundwater with riparian buffers. This paper presents a system to classify these riparian opportunities and apply them toward riparian management planning in hydrologic unit code 12 watersheds. In two headwater watersheds from each of three landform regions found in Iowa and...

The natural removal of NO3 by denitrification within riparian zones of streams and rivers is an area of considerable interest owing to its potential to minimize the impacts of excess anthropogenic loadings. In this study we utilize natural variations in stable N isotopic compositions of NO3 and NH4 within a transect of shallow wells extending 4 m inland from Smith Creek, a southwestern Michigan...

This paper presents an assessment of groundwater quality and quantum in the command areas two secondary canals lower Sindh, southern province Pakistan. These off-take from Rohri main canal Sukkur barrage Indus basin system. The scarcity water is due to climate change, population growth increased demands. farming community uses meet needs improve their livelihood. fresh Sindh only 22 percent, wh...

22 Groundwater contamination was characterised using a methodology which combines 23 shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a 24 statistical framework and hydrogeological techniques. Nitrate-N (NO3-N) 25 contaminant mass flux was calculated across three control planes (rows of 26 piezometers) in six isolated plots. Results showed natural attenuation occu...
