Conditioning DRASTIC model to simulate nitrate pollution case study: Hamadan–Bahar plain

Assessing the groundwater vulnerability to pollution using DRASTIC and SINTACS models, case study: Evan Plain, south west of Iran

modification of drastic model to map groundwater vulnerability to pollution using nitrate measurements in agricultural areas

drastic model has been used to map groundwater vulnerability to pollution in many areas. since this method is used in different places without any changes, it cannot consider the effects of pollution type and characteristics. therefore, the method needs to be calibrated and corrected for a specific aquifer and pollution. in the present research, the rates of drastic parameters have been correct...

Application of SWAT Model to Simulate Nitrate and Phosphate Leaching from Agricultural Lands to Rivers

In the present study, the amount of nitrate and phosphate leaching from agricultural lands into the Zanjanrood River in Iran was simulated using the Soil & Water Assessment Tool (SWAT) model. The measured average monthly discharges at the Sarcham station were used to calibrate and validate the SWAT model, and the SWAT Calibration and Uncertainty Program (SWAT-CUP) model was applied to perform t...

Assessment of Social Vulnerability to the adverse effects of air pollution: A case study: Sistan Plain

Background & Aim: The Sistan region with over 320 dry days is one of the focal points of the rainstorms, and every year the number of days with dust increases, which results in socio-economic consequences for more than 400,000 people in the region. This study investigated the social vulnerability of the population to air pollution with a different perspective. Methods: The present study is a d...

the comparison of fuzzy drastic model and conventional drastic model to determine the most appropriate indicator of ground water vulnerability, case study: sarkhoon plain aquifer

introduction drastic model is an index and overlapping model that has been designed for producing vulnerability scores for different points by combining several thematic layers. overlapping distinguished methods are themost applicable methods for evaluatingvulnerability of aquifers because they are cheap, they can directly reach a defined goal, the used data in the methods are accessible or can...
