This study is aimed to use the available limited meteorologicaland hydrological data for two catchments located in the westernIraqi desert, to develop and apply a simple single event watershed model to simulate and predict the surface runoff hydrograph. The single event watershed model is based on the water balance equation. The inputs to the model...
Land affccted by desertification processes have been increasing at an alartning rate 00 a watid scale, approaches 30% of the global surface in arid areas (40-45 1Ikm2) \vhere nears 600 million peopIe live while 4% oE the global surface corrcsponds to deserts with nearly 60 million inhabitants. In thi5 articula te, a methodology i5 presented [O! the...

Floristic composition, morphological functional types and habitat distributions for C4 species were studied in Xinjiang, North-western China. 89 species, in 9 families and 41 genera, were identified with C4 photosynthesis. 48 % of these C4 species were found in Monocotyledoneae, e.g. Cyperaceae (5 species), Gramineae (38 species), the other 52 % wa...
Su kaynaklarının etkin bir şekilde planlanması ve yönetimi için yağışın doğru bir şekilde tahmin edilmesi büyük önem taşımaktadır. Hidrometeorolojik zaman serilerinin tahmini, zaman serisini etkileyen parametrelerin belirsizliğinden dolayı en zor işlerden biridir. Yapay sinir ağlarına dayalı kurak bölge yağış tahmin modelleri literatürde çok sınırl...

To improve the simulation of the surface radiation budget and related thermal processes in arid regions, three sophisticated surface albedo schemes designed for such regions were incorporated into the Biosphere-Atmosphere Transfer Scheme (BATS). Two of these schemes are functions of the solar zenith angle (SZA), where the first one has one adjustab...

Species, coverage, density, appearance, important values and above ground biomass of desert plant communities in the Hexi Corridor region in northwestern China were investigated. Data on the meteorological factors at the investigation sites were collected. Their relationships were statistically analyzed. The results show that the composition of pla...

The Agua Fria River in Arizona’s Sonoran Desert was impounded and diverted more than 70 years ago. Immediately below New Waddell dam there are semi-permanent pools, but water has been released into the channel only during rare wet years. To determine whether a propagule bank exists below the dam, and whether it could contribute to the revegetation ...

The GRACE (Gravity Recovery and Climate Experiment) satellite gravity mission has provided a new method to study land water mass redistribution at medi- and long-spatial scales in recent years. We estimate continental water mass redistribution in China using GRACE observations during 2003 to 2007. The results show some large regions with increase o...

Tree-crop interactions were monitored by measuring tree growth characters of Prosopis cineraria L. and Tecomella undulata L. and yields of Vigna radiata (L) in agroforestry systems in degraded lands of Indian Desert. Potential competition for resource between the trees and associated crop was analyzed by measuring soil water contents, soil organic ...
A field experiment was conducted during 1993–1995 to study the effect of industrial effluent on the initial growth of Azadirachta indica A. Juss. (Neem) in arid region. The effluent released from textile industry had high pH, EC, SAR and RSC. Various treatments were: irrigation with effluent only (W1), effluent mixed with canal water at 1:1 ratio (...
