Due to the important role of climatic parameters such as radiation, temperature, precipitation and evaporation rate in water resources management, this study employed time series modeling to forecast climatic parameters. After normality test of the parameters, nonparametric Mann-Kendall test was used in order to do trend analysis of data at P-value<0.05. Relative humidity and evaporation (with ...
Creating innovative ways for the identification of trends is a very vital part atmospheric studies. Different climatic locations present their unique variations, calling dynamism trend analysis. In addition to widely adopted Mann–Kendall (MK) test, new Şen’s analysis (ITA) method has been applied analyze refractivity related (atmosphere pressure—AP, vapour pressure—VP, ambient temperature—T) an...
in order to study the reason for the prominent increase of the average of sugar content in sugar beet produced in iran in 2007 and finding the relation of this increase with climatic parameters, chenaran sugar factory district was chosen. due to precise and reliable statistical data of sugar factory during the campaign and weather data, chenaran sugar factory was chosen for this investigation. ...
Mangroves are among the most well described and widely studied wetland communities in the world. The greatest threats to mangrove persistence are deforestation and other anthropogenic disturbances that can compromise habitat stability and resilience to sea-level rise. To persist, mangrove ecosystems must adjust to rising sea level by building vertically or become submerged. Mangroves may direct...
climate change is one of the most important challenges in recent years. heavy flood, hot weather, early coldness, most of drought replications, risen of sea water level, pests and plant disease ,reducing of ozone layer thickness, global worming ,and melting ices, are cases that introduced climate change issue in recent decades more. climate is one of the most important factors for crop chang...
Rangelands are one of the most vulnerable parts concerning the climatechanges‟ impacts. These impacts are even stronger in the arid and semi-arid areas whererangeland ecosystems are in critical conditions. Therefore, it is crucial to figure out theactual dynamics of climate variations on the rangelands. The aim of this research was todetermine climate changes in Khabr rangeland, Kerman, Iran. S...
Identification of climatic characteristics affecting the annual yield of Rheum Ribes can be useful in management and development of this species in the rangelands. In this research, the annual yield of this species in Khorasan-Razavi province based on 74 climatic parameters during a ten-year period evaluated and affecting climatic parameters extracted using data mining methods. First, the role ...
Variability is an inherent characteristic of neritic fisheries. This is usually associated with both heavy fishing and changes in environmental conditions. Consideration needs to be given to the biological, physical and human components of the management system. This includes controlling the type, size and amount of fish harvested; trying to respond in a timely manner to events in the fishery i...
