Connectivity of urban green patches is an important structural attribute of urban landscape that facilitates the species movement and transfer of their genes among their habitats. So far, several methods including Graph Theory have been applied to assess ecological connectivity. This research was aimed to study the application of graph theory to measure the connectivity of green patches in the...
Downslope soil movement along riverbanks is a significant erosion process. Plant roots, particularly of woody vegetation, apparently stabilize soil on slopes because in most areas where the vegetation is removed, frequent bank failure occurs. Plant roots increase soil-shearing resistance both directly by mechanical reinforcement and indirectly through removal of pore water by transpiration. In ...
The main sources of cadmium in soil-plant continuum in amounts that might present a hazard are liquid and solid wastes of sewage sludge, farm manures and fertilizers. In the southwest of Iran (Khuzestan Province) over 50,000 ha of land is under sugarcane (Saccarum officinarum) cultivation and more than 80,000 ha will be under sugarcane by the end of the year 2000. In these sugarcane fields, abo...
One of the most important subjects in relation of water resources quality in the many of river is the chemical composition of waters and conservation of water quality in the watershed. Geological formations in any region of the earth are the main surface and foundation that water flows on the bed and strata of formation, which in fact they affect their characteristics on water quality as positi...
limited information is available on water and nitrogen (n) management of sugarcane (saccharum officinarum l.) in khuzestan, southwestern iran, where this crop is currently and extensively grown under heavy irrigation and n fertilization. therefore, a field experiment was conducted from september 2000 to march 2002 at the research department of karoon agro-industry in khuzestan to determine the ...

predictions of suspended sediment load for soolegan river, iran using selected empirical equ-ations were made based on 355 data sets. data include flow discharges from 3.11 m3/s to 43.81 m3/s, flow velocities from 0.22 m/s to 1.03 m/s, and flow depths from 0.5 to 1.03 m. equations of einstein (1950), bagnold (1966), toufalleti (1968), brooks (1963), chang-simons-richardson(1965),lane-kalinske (...
in western and southern watersheds of isfahan province, combinations of natural and human factors have caused numerous landslides related damages. one of the main strategies for restricting the damage caused by the landslide is to avoid these regions. for this purpose, it is necessary to prepare precise landslide hazard zonation map for such areas. for this purpose, by aerial photos, satellite ...
Effects of different levels of nitrogen fertilizer and cutting time of forage on grain and forage yield of barley (Hordeum vulgare L.) Karoon cultivar was studied during 1995-1996 at Ramin Agricultural Research and Educational Center, University of Shahid Chamran, Ahwas, by using a split plot design in randomized complete block with 4 replications. Main plots were assigned to five levels of N f...
