Comparative Study of Frequency Analysis and Hydro-climatic Methods for Estimating Maximum Flood Discharge (Case Study: Bakhtiary Watershed)

Mohammad Bashirgonbad; Alireza Moghaddam Nia; Shahram Khalighi Sigaroodi; Mohammad Mahdavi; Emmanuel Paquet; Michel Lang

Volume 71, Issue 3 , December 2018, , Pages 595-612


  There are many methods for estimating the maximum flood discharge including frequency analysis methods and risk study of hydraulic structures based on flood frequency analysis is often sensitive to the observations and selected statistical distribution that cause errors in design. Since heavy rainfalls ...  Read More

Study of Groundwater Quality of Mashhad Aquifer using GIS and Multivariate Statistical Techniques

mahboobeh sarbazi; Sadat Feiznia; Mohammad Mahdavi

Volume 71, Issue 3 , December 2018, , Pages 645-657


  Water quality is always one of the major challenges for managers and decision makers in water resource management. However, the problems of water quality are more important than quantity. One of the main ways in thorough review and assessment of water quality using multivariate statistical techniques ...  Read More

Assessing the effectiveness of the analytic hierarchy process as a groundwater predicting tool (Case study: Ghorve-Dehgolan plain)

Omid Rahmati; Aliakbar Nazari Samani; Mohammad Mahdavi

Volume 70, Issue 4 , January 2018, , Pages 869-879


  Determination of groundwater potential in respect to increasing trend of water demand in Iran, is found to be an unavoidable and vital subject. The present research was aimed to assess the efficiency analytical hierarchical process (AHP) to identify potential groundwater zones. Initially, five parameters ...  Read More

Evaluation of groundwater changes in an arid shallow aquifer using groundwater level, electrical conductivity and temperature time series analysis

hamid hosseyni marandi; mohammad mahdavi; hasan ahmadi; baharak motamed vaziri; abdolali adelpour

Volume 70, Issue 3 , December 2017, , Pages 633-645


  Abstract Common causes for groundwater quantity and quality changes are infiltration through the seasonal floodwater, effects of the artificial recharge projects and adjacent aquifers, and groundwater extraction for deferent uses. However, recognizing the impact of their contributions to these changes ...  Read More

Simulation of Daily Stream Flows in Semi-Arid Mountainous Watersheds using Hydrological Simulation FORTRAN Program (HSPF)

Ja'afar Dastorani; Mohammad Mahdavi; Ali Salajegheh; Ahmad Fakheri Fard

Volume 70, Issue 1 , June 2017, , Pages 87-100


  Hydrological Simulation FORTRAN Program (HSPF) has long been used in modeling watersheds and many studies have been carried out around the world in this regard. Hablerood watershed is located in Semnan province with an area of 3200 km2 which suppies the required water, especially for farming, in Garmsar ...  Read More

Trend analysis of streamflow in Karkheh Rivers upstream: An evidence for climate change impacts on water resources systems

Khaled Osati; Ali Salajegheh; Mohammad Mahdavi; Paul Koeniger; Kamran Chapi; Arash Malekian

Volume 68, Issue 3 , October 2015, , Pages 659-674


  Within the climate change debate and its probable impacts on water resources systems, design and operation of management plans based on the assumption of stationary hydrology may cause serious challenge to accurately predict future supplies. Therefore this case study is trying to assess trend in hydroclimatic ...  Read More
