Leila Goli Mokhtari; Najme Hshafiei; Abolalfazl Rahmani

Volume 5, Issue 17 , March 2019, Pages 1-21

Abstract
  Introduction Soil erosion is a phenomenon that typically occurs in a large part of the earth and the exacerbation of this process, as a limiting factor, can be an obstacle to the management of the land. It reduces the soil fertility and results in the desertification of the fields and the sediment deposited ...  Read More

Using Hybrid Wavelet-Support Vector Machine and Wavelet-Neural Network Models for Groundwater Level Prediction in Ardabil Plain

Farnaz Daneshvar Vousoughi; Vahid Manafianazar

Volume 5, Issue 17 , March 2019, Pages 45-64

Abstract
  Abstract Groundwater has played an important role in the urban and rural water supply and agriculture. In order to manage water resources, an accurate and reliable groundwater level forecasting is needed. In this research, 15 piezometers in Ardabil plain were used. SVM was applied for a prediction method ...  Read More

Zoning Suitable Areas for Artificial Recharge Aquifers of Sabzab and Gotvand Plains Using Fuzzy Model and Matching of the Alluvial Fan

Nezam Asgharipour Dasht Bozorg; Mohammad Reza Servati; Pervez Kardavani; Siavash Shayan

Volume 5, Issue 17 , March 2019, Pages 65-84

Abstract
  Introduction Alluvial fans have a great importance in terms of their high efficiency to create natural aquifer and groundwater storage. Increasing the rate of water demand and relying on groundwater has caused a remarkable decline in groundwater resource and aquifer level. On the other hand, flood spreading ...  Read More

Flood Hazard Zonation by Combining SCS-CN and WLC Methods (Case study: Khiyave Chay Meshkinshahr Basin)

Aghil Madadi; Elnaz Piroozi; Leila Aghayary

Volume 5, Issue 17 , March 2019, Pages 85-102

Abstract
  Introduction One of the most striking natural hazards in the world is flood which generates a lot of financial and human losses every year. It can be said that in comparison with other natural hazards, it occurs with high abundance and in vast expanses. Some of its causes can be severe or prolonged ...  Read More

The Optimization of SINTACS Framework Using MFL Model to Evaluate the Vulnerability of Bilverdi Aquifer

AtaAllah Nadiri; Esfandiar Abbas Novinpour; Rana Faalaghdam; Zahra Sedghi

Volume 5, Issue 17 , March 2019, Pages 103-123

Abstract
  Introduction Population growth and the development of the agriculture and industry and the excessive use of groundwater resources have caused a drop in the water level. In arid and semi-arid areas, aquifer water management plays an appropriate role within human health of river basins and, therefore, ...  Read More
