Detecting Temporal Variations of Temperature Characteristics in Jinghe Watershed

Detecting temporal change in watershed nutrient yields.

Meta-analyses reveal that nutrient yields tend to be higher for watersheds dominated by anthropogenic uses (e.g., urban, agriculture) and lower for watersheds dominated by natural vegetation. One implication of this pattern is that loss of natural vegetation will produce increases in watershed nutrient yields. Yet, the same meta-analyses also reveal that, absent land-cover change, watershed nut...

Temporal Variations of Fire Effects on Dissolved Nutrient Concentrations and Runoff amount in Zrebar Lake Watershed

Fire causes destructive effects on soil, water and components of wetland ecosystems. The aim of this study was to investigate the effects of fire on runoff amount and nutrient concentration of Zrebar Lake watershed between 2014 and 2017 and the return of burned areas to their natural conditions in the short, medium and long term. The results showed that in the fourth year after the fire, the am...

Assessment of spatio-temporal variations of surface water quality and prioritization of pollution Sources (case Study: Talar Watershed, Mazandaran province)

Evaluating the Spatial-Temporal Variations of Rainfall Erosivity and Erosivity Density (A Case Study: Menderjan Watershed, Isfahan Province)

Rainfall erosivity is one of the factors determining the amount of water erosion in the soil. Rainfall erosivity is determined by the  total rainstorm energy and the maximum intensity in 30 minutes (I30). Since rainfall erosivity is closely related to the amount and intensity of rainfall, it is expected that the rainfall erosivity would change monthly and seasonally throughout the year. The mai...

seasonal and temporal variations in physico-chemical and bacteriological characteristics of river ganga in varanasi

various physico chemical characteristics of the river ganga in varanasi were studied in the oct 2005 to nov 2006. ecological parameters like dissolved oxygen(do), ph, nitrate(no3-), po43- and bacterial population were analyzed and compared with standard permissible limits to assess the best designated use of the river water for various purposes. study revealed that the water quality at varanasi...
