Awareness and performance of the bakers regarding the prevention of covid-19 in Iranshahr city, 2020
Background & Aim: It is possible for food-related staff to be involved in transmitting covid-19 by their contact such as coughing or sneezing. Therefore, the knowledge of food-related staff about the transmission modes and prevention of covid-19 is very important. This study was conducted with the aim of investigating the awareness and performance of bakers working in Iranshahr city regarding t...
An approach for regional low flow frequency analysis is to use multiple regression techniques for obtaining relationships between low flows with specific return periods and catchments characteristics. In this paper, this method has been used. After single-site frequency analysis for 20 stream gauging stations, homogeneity test was performed. Regional relationships between low flows with return ...
Hydrological, hydrodynamic and water quality models are often used to simulate surface water in a correct way to be a good basis for decisions regarding the development and management of water resources. Molenbeek is one of the main tributaries of the River Dender basin (Belgium). The hydraulic model is implemented by using the MIKE 11 software of the Danish Hydraulic Institute (DHI). It is a v...
In this study, the pollution of the Revenj River sediments with heavy elements has been studied. Revenj River catchment with an area of 131 Km2 is located 20 kilometers from the city of Torbat-e-Jam (northeast of Iran). To investigate the contamination of sediments with heavy elements, 15 samples of sediments were taken from the area and analyzed by ICP-MS. In order to monitor the contamina...
We offer a model for integrated water quality management. The proposed model integrates water protection, land and water use, preservation of ecosystem sustainability, preservation of functional unity of catchment and river flow and socio-economic activity in the catchment. The model has been developed on the basis of combining existing models, including balancing, deterministic (2D) and statis...
Parameterization of physically based and distributed hydrological models for mesoscale catchments remains challenging because the commonly available data base is insufficient for calibration. In this paper, we parameterize a mesoscale catchment for the distributed model HydroGeoSphere by transferring evapotranspiration parameters calibrated at a highly-equipped headwater catchment in addition t...
Catchment urbanisation leads to increased hydraulic and pollutant loadings into receiving waterbodies. Issues concerning pollution that endangers the sustainable utilisation of water resources have focused government authorities towards integrated catchment management, where both causes and effects of pollution are addressed. Recent research has provided a platform for improving urban stormwate...
In this study biogeochemical export in a set of catchments that vary from 6ha to almost 1500ha is investigated. Studying catchments across this large range of scales enables us to investigate the scale dependence and fundamental processes controlling catchment biogeochemical export that would not have been possible with a more limited data set. The Devil Canyon catchment, in the San Bernardino ...
because of the presence of special properties in semi arid catchment, these areas are suitable for drought events. the responses of these areas to drought events are in the form of the disappearance of plant cover on surfaces slopes, intensive erosion or landslide occurrence on side of riversâ course. azarshahr catchment (situated in 37ë 36â² to 37ë 49â² n and 44ë 20â² to 45ë 49â² e) ...
