We present a forecast-based adaptive management framework for water supply reservoirs and evaluate the contribution of long-term inflow forecasts to reservoir operations. Our framework is developed for snow-dominated river basins that demonstrate large gaps in forecast skill between seasonal and inter-annual time horizons. We quantify and bound the contribution of seasonal and inter-annual fore...

In deepwater-reservoir modeling, the proper representation of the spatial distribution of architectural elements is important to account for pore-volume distribution and the connectivity of reservoir sand bodies. This is especially critical for rock and fluid-volume estimates, reservoir-performance predictions, and development-well planning. A new integrated stochastic reservoir-modeling approa...

Management decisions related with water quality in lakes and reservoirs require a combined land-water processes study approach. This study reports on an integrated watershed-reservoir modeling methodology: the Soil and Water Assessment Tool (SWAT) model to estimate the nutrient input loads from the watershed, used afterwards as boundary conditions to the reservoir model, CE-QUAL-W2. The integra...

the assessment of the quantitative and qualitative changes, the result of the impacts imposed by natural factors, and human interventions during specific sampling periods has a substantial influence on nature, management method and tending operation of every region’s forests. the present research was carried out in golestan province forests (iran) over an 11- year period and the obtained statis...

Phlebotomus papatasi is an important vector of L. major in Iran. P. papatasi was collected from peridomestic animal shelters, inside and around the houses and also the nearby burrows of the gerbil reservoir hosts, Rhombomys opimus, in several provinces in Iran. Mitochondrial Cytochrome b (Cyt b) of sandflies, which is a maternally-inherited gene marker, was used to see if there is any "isolatio...

Umbelliprenin is a prenylated compound, which belongs to the class of sesquiterpene coumarins. It is extracted from dried roots of Ferula szwitsiana collected from the mountains of Golestan forest (Golestan Province, north of Iran). Induction of apoptosis in Jurkat T-CLL cells has been previously shown. In this study, effect of umbelliprenin on proapoptotic caspases (caspase-8 and -9) and antia...

Soil is well known to support the transient or ongoing existence of kerathophilic fungi and potential sources of infection for humans and animals. Fifty soil samples were collected from various areas of forests and farmyards at Golestan Province in the north part of Iran to determine the prevalence of keratinophilic fungi and dominant species. A total of 357 fungal colonies including 13 genera ...

Dams control most of the sediment entering the reservoir by creating static environments. However, sediment leaving the dam depends on various factors such as dam management method, inlet sediment, water height in the reservoir, the shape of the reservoir, and discharge flow. In this research, the amount of suspended sediment of Doroodzan Dam based on a statistical period of 25 years has been i...

Area-volume-elevation (AVE) curves of dams pose one of the most important tools for water resource planning and reservoir management. Area reduction method is one of the methods which was developed to modify these curves after reservoir sedimentation based on the conditions, statistics and information recorded in reservoirs abroad; however the application of the same methods for domestic dams w...
