Unfortunately, th.re h.s been no detai.ed study to analyze th. damages of sea water i.trusi.n at a large temporal and spati.l scale. Th.refore, th.s study i. desi.ned to esti.ate th. effects of sea water i.undati.n based on ch.ngi.g sea water surface sali.i.y and sea surface temperature(SST). Sea surface sali.i.y and SST data from two di.ferent surveys i. Daboo creek duri.g 1986 and 2010 are analyzed to esti.ate th. damages and extent of sea water i.trusi.n.

Understandi.g th. effects of cover crops and ti.lage on soi. ph.si.al properti.s i. i.portant for determi.i.g soi. producti.i.y. Th.s study was conducted at Li.coln Uni.ersi.y＇s Freeman Center, USA to evaluate th. effects of ti.lage and cover crop management on soi. h.drauli. properti.s. Th. fi.ld si.e i.cluded th.ee repli.ate blocks i. a randomi.ed complete block desi.n wi.h.each.plot measuri.g 21.3 m i. length.and 12.2 m i. wi.th. Treatment factors were ti.lage at two levels （moldboard plow ti.lage vs. no ti.lage） and cover crop at two levels （cereal rye （Secale cereal） cover crop vs. no cover crop）. Soi. samples were collected i. late spri.g/early summer from each.treatment at 10-cm depth.i.crements from th. soi. surface to a depth.of 40 cm usi.g cores （76.2-mm di.meter and 76.2-mm length.. Soi. bulk densi.y was 13% lower wi.h.ti.lage compared wi.h.no-ti.lage. Volumetri. water content was si.ni.i.antly h.gh.r at 0.0 and -0.4 kPa pressures wi.h.ti.lage compared wi.h.no ti.lage. Ti.lage i.creased th. proporti.n of coarse mesopores by 32gc compared wi.h.no ti.lage, resulti.g i. 87% h.gh.r saturated h.drauli. conducti.i.y （Ksat）. Cover crop i.creased th. proporti.n of macropores by 24~ compared wi.h.no cover crop; th.s can potenti.lly i.crease water i.fi.trati.n and reduce runoff. As a result of h.gh.r macroporosi.y, Ksat was h.gh.r under cover crop compared wi.h.no cover crop. Th.s study demonstrated th.t ti.lage can benefi. soi. h.drauli. properti.s i. th. sh.rt term, but th.se effects may not persi.t over ti.e. Cover crops may sli.h.ly i.prove soi. h.drauli. properti.s, but longer term studi.s are needed to evaluate th. long-term effects.
