Prediction of watershed responses and simulation of runoff rate and volume are required for design purposes in most water resources projects. For this purpose, different hydrologic methods and events based on continuous hydrologic mathematical models are applied. In this research, a continuous hydrologic model, Stanford Watershed Model-IV (SWM-IV) is used for simulation of annual and monthly vo...
Most of our country is located in arid and semiarid climate which have high soil erosion and sediment production, therefore, the study of soil erosion and sediment yield and also evaluation of the effective factors on sediment production are very important in proper management of a watershed. The aim of present study is the efficiency evaluation of MUSLE model in sediment estimation in the stor...
AIM Both observational and experimental studies have shown that higher selenium status reduces the risk of upper gastrointestinal cancers in selenium deficient populations. Recent cancer registry data have shown very different rates of esophageal cancer (EC) and gastric cancer (GC) in four Provinces of Iran, namely Ardabil, Mazandaran, Golestan, and Kerman. The aim of this study was to have a p...
Airborne-based Light Detection and Ranging (LiDAR) offers the potential to measure snow depth and vegetation structure at high spatial resolution over large extents and thereby increase our ability to quantify snow water resources. Here we present airborne LiDAR data products at four Critical Zone Observatories (CZO) in the Western United States: Jemez River Basin, NM, Boulder Creek Watershed, ...
A survey was carried out to investigate the prevalence of hard tick species (Acari: Ixodidae) on cattle in Mazandaran province, Iran. A total of 953 ticks were collected from 86 infested cattle during activating seasons of ticks during 2004-2005. Nine species were identified: Boophilus annulatus (51.3%), Rhipicephalus bursa (16.8%), Haemaphysalis punctata (6.3%), Ixodes ricinus (6.8%), Hyalomma...
In many floods controlling, watershed-management and water-resources projects, estimating of river flow-rate is important and needs a comprehensive hydrological modeling of flow-rate evaluation. Need for enlightening the status of water-resources and precipitation in different watersheds and the lack of networks of hydro-meteorological gauging stations, reveal the importance of estimating ...
Gully erosion and sedimentation have high priority in Fars Province due to the losses from destruction of lands, roads and civil structures. In the present study, in order to evaluate the threshold for the development and initiation of gully topography in Fars province, two regions were selected including Allamarvdasht, Lamerd and Fedagh, Larestan. 30 gullies were selected in each mentioned are...
Hydrological response of a watershed is a comprehensive symbol of environmental conditions and characteristics of the basin. Vegetation is one of the main factors in water resources status, erosion, and sediment of a watershed. Rangelands of Golestan province, Iran due to the geographical location, climate, and destruction of these resources as well as drastic land use changes from forests, and...
BACKGROUND The prevalence and etiology of infertility are not similar in different parts of the world. There are only few reports of this topic in Iran. OBJECTIVE This study was conducted to determine the clinical patterns and major causes of infertility in Mazandaran province in north of Iran. MATERIALS AND METHODS The medical records of 3734 consecutive couples attending two infertility c...
