Regression Patterns of Diurnal Temperature in Different Climatic Regions of Iran

B. Mirkamandar; Seied Hosein Sanaei-Nejad; H. Rezaee-Pazhand; M. Farzandi

Volume 34, Issue 5 , November and December 2020, , Pages 1141-1156

https://doi.org/10.22067/jsw.v34i5.76165

Abstract
  Introduction: The behavior of daily changes in temperature is not straightforward. We first drew the curve of this variable on a normal day. It can be seen that the distribution of this variable was not normal. The curve of this variable was a skewed curve to the right. Therefore, the equal coefficients ...  Read More

Modification and Application of Simple Regression Models to Predict Annual Precipitation in Shahrekord and Yazd Weather Stations

N. Khalili Samani; A. Azizian

Volume 30, Issue 1 , March and April 2016, , Pages 312-321

https://doi.org/10.22067/jsw.v30i1.41933

Abstract
  Interduction: Spatial and temporal improper distribution of precipitation is one of the major problems in the water district. Increasing population and reduction per capita fresh water has made freshwater resources as a renewable to a semi-renewable source (1). Rainfall is one of the climatic variables ...  Read More

Estimation and Mapping Soil Organic Carbon content using Terrain Analysis(Case study: Mashhad, Iran)

A. Lakzian; M. Fazeli Sangani; Alireza Astaraei; A. Fotovat

Volume 27, Issue 1 , March and April 2013, , Pages 180-192

https://doi.org/10.22067/jsw.v0i0.22228

Abstract
  This study was conducted to evaluate using terrain attributes derived from digital elevation model (DEM) as ancillary data to predict soil organic carbon (SOC) by implementing different statistical and geostatistical techniques. A linear regression model (LR), Artificial Neural Network model (ANN), ordinary ...  Read More

Study of River Flow Effects on Subsurface Water Diversion Using Porous Media in Seasonal Rivers

R. Mansouri; K. Esmaili; A.N. Ziaei; Hossein Ansari; S. R. Khodashenas

Volume 26, Issue 5 , November and December 2012, , Pages 1200-1214

https://doi.org/10.22067/jsw.v1391i0.17049

Abstract
  In arid and semi-arid regions, collection of surface and subsurface waters in small seasonal rivers is very crucial, particularly in dry seasons. The cost of construction and maintenance of classical water intakes makes them inappropriate for these rivers. In this study a rather new method to divert ...  Read More
