The aim of this study is to identify the influencial factors on groundwater drought in HamadanBahar Watershed,Iran, to understand the forcing mechanisms. The Standardised Precipitation Index (SPI) has been used to quantify the evaluation of meteorological to drought effects in the reduction of ground water table. The influence of land use patterns on the groundwater table drought also has been identified using remote sensing teqnique. The results show that in recent decades ground water table trend has been negative, water table has fallen around 17.91 meters in time period of 1992-2011, that its annual average is equal 0.90 meters. Also, result shows that drought intensity is more severe during the dry years. The rainfall deficit has a significant effect on meteorological drought which has a direct re...

The objective of this study was to compare the methods of precipitation spatial interpolation, namely, the method of Thiessen polygons (THI), Inverse Distance Weighting (IDW), and Universal Kriging (UNK) using the physically based and spatially distributed hydrological WetSpa model. The paper also illustrates how these methods allow more accurate estimation of river discharge simulated with the WetSpa model for the Gharesou basin in Iran. Daily data of 22 precipitation gaging stations were used in this study. In order to simulate hydrological processes for the basin, especially river runoff, we used the precipitation data interpolated with THI, IDW, and UNK as well as digital information on topography, the land use and soil type of the basin. For comparing three interpolation methods, they were applied to the simulation of river discharge using the WetSpa model. Simulated daily values of water discharge in the basin were compared with observational data. The quality of data simulated using these three methods was very good or excellent. According to the efficiency criterion of Aggregated Measure (0.879), the application of THI method provided more accurate forecast of river discharge than that of IDW and UNK methods.

First, specific sediment yield was simulated using spatially distributed hydrological WetSpa model, then the influential factors such as morphometric variables, land-use composition and pattern and soil properties of the watershed were calculated at the sub-watershed scale. Due to the inter-reliant of these watershed characteristics, a partial least squares regression (PLSR) was used to illustrate the relationship between the specific sediment yield and data of 15 selected watershed characteristics. The results showed that the land-use composition and soil properties had the maximum effects on the specific sediment yield and clarified 79% of the variation in the specific sediment yield. Regarding the availability of digital spatial database over the watershed, this simple PLSR procedure could be applied in different watersheds.

In addition, because of nonlinear trend of snow spatial distribution and the multiple influencing factors concerning the SWE spatial distribution, statistical models are not usually able to present acceptable results. Therefore, applicable methods that are able to predict nonlinear trends are necessary. In this research, to predict SWE, the Sohrevard Watershed located in northwest of Iran was selected as the case study. Database was collected, and the required maps were derived. Snow depth (SD) at 150 points with two sampling patterns including systematic random sampling and Latin hypercube sampling (LHS), and snow density at 18 points were randomly measured, and then SWE was calculated. SWE was predicted using artificial neural network (ANN), adaptive neuro-fuzzy inference system (ANFIS) and regression methods. The results showed that the performance of ANN and ANFIS models with two sampling patterns were observed better than the regression method. Moreover, based on most of the efficiency criteria, the efficiency of ANN, ANFIS and regression methods under LHS pattern were observed higher than the systematic random sampling pattern. However, there were no significant differences between the two methods of ANN and ANFIS in SWE prediction. Data of both two sampling patterns had the highest sensitivity to the elevation. In addition, the LHS and the systematic random sampling patterns had the least sensitivity to the profile curvature and plan curvature, respectively.

The Ardak watershed was selected as the study area due to encountering several cases of open garbage dumps and uncontrolled landfills which are one of the main sources of river water pollution in the upstream of the Ardak dam. The results revealed that the proposed algorithm successfully assists in inventory-irrespective probabilistic modeling of landfill siting which is mainly indebted to the role of areal constraining in providing training and validation samples for the Mahalanobis distance model. The latter also showed a robust pattern recognition results from which a discernible differentiation of the area was attained while the spatial dependencies between the environmental factors were taken into account. Mahalanobis distance also gave an outstanding performance in terms of goodness of fit (area under the success rate 89.367) and prediction power (area under the success rate 89.252). Based on a five-point scale classification scheme, about 2.7% and 2.6% of the study area, respectively, have high and very high suitability for landfilling, while the remaining area is shared between very low-to-moderate suitability classes. According to the current trail of literature regarding landfill site selection which mostly relies on mere areal filtering, a probabilistic model would give invaluable inferences regarding the pattern of suitability/susceptibility of the area of interest and causative role of the influential factors.
