Rainfall simulation experiments were conducted on annual grassland and coastal sage scrub hillslopes to determine the quantities of C and N removed by surface runoff in sediment and solution. Undisturbed coastal sage scrub soils have very high infiltration capacities (> 140 mm h(-1)), preventing the generation of surface runoff. Trampling disturbance to the sage scrub plots dramatically reduced...

Three first-, secondand third-order experimental forested watersheds located within the Francis Marion National Forest in the lower coastal plain of South Carolina were monitored for rainfall and stream outflows. The largest watershed (WS 78) with some open lands, roads and wetlands gave higher annual water yields compared to the two other smaller ones (WS 79, WS 80) with mostly forest vegetati...

Salt marshes are globally distributed, vegetated intertidal wetlands and marsh edge erosion is common on many shores. To understand how why occurs, the response of salt substrates to applied shear vertical stress must first be quantified. This likely influenced by substrate biological, geochemical sedimentological composition. However, currently there little systematic research into between-mar...

Salinity intrusion worldwide is a problem of consideration for the global food production and ensuring security. In this investigation, we focused to find out key chemical elements salinity problem. paper, authors reported high accumulation sodium (Na + ) increased EC (6.9 dS/m) values than that previous year (4.67 dS/m). We found highest EC, Na +, ESP 6.9 ds/m, 2.6 meq/100 g soil, 19.1%, respe...

The effects of long-term lime and K applications on quantity-intensity (Q/I) relationships were investigated on the Ap and B21t horizons of a Kalmia soil (a fine-loamy over sandy or sandy-skeletal, siliceous thermic (Typic Hapludults) from the Delaware Coastal Plain. The predominant mineral suite of the <2faa clay fraction was mica, vermiculite, and chloritized vermiculite. Soil pH and exchange...

Mangroves dwell at the land-ocean interface and are thus encroached upon by competing land use at the coastal zone. They are also subject to impacts from catchments developments. As a result, mangroves worldwide are having their extension changed (Spalding et al, 1997). Worldwide it is well accepted that mangrove extension is decreasing mostly due to conversion to other uses, in particular aqua...

counties (Torrent et al., 1980), and in soils formed in late The morphologic development of soils on marine terraces is a function of terrace age and geomorphic evolution. In this study, inter­ relationships between terrace landscape evolution and pedogenic sil­ ica cementation were investigated. Soil morphology, micromorphol­ ogy, selective dissolution, penetration resistance, and hydraulic co...
