In this research work, copula-based methodology is adopted to analyze the hydrological drought frequency. Standardized Runoff Index SRI was calculated using monthly-streamflow data for 50 years of two gauging stations in northern region Iraq. The duration and severity were extracted run theory. Three Archimedean family Gaussian copulas used compared select most appropriate copula model bivariat...

Salinisation is a major environmental problem affecting land and water systems in Australia. This paper outlines a study currently being undertaken to provide a new tool to manage salinity from environmental and socioeconomic perspectives. In this study, biophysical and socio-economic aspects of the Little River Catchment and their relevance to salinity management will be investigated using a B...

Impacts of land cover changes on watershed hydrology have been a long-term academic concern with acute dispute. But little attention has been paid to such effects on mesoscale river basins, where the society has a closer link to river hydrology. The present study focuses on a mesoscale river basin, the Suomo Basin that is located on the upper reaches of the Yangtze River. Land covers in the bas...

Walleyes experience spawning runs each spring in the Tamarac River, a tributary of the Red Lakes. However, data about walleye egg survival in the lake and river is lacking. Mesh cages were placed in both the Tamarac River and Upper Red Lake to compare survival rates. A total of twenty cages were set, ten in the river and ten in the lake. Each cage contained one hundred fertilized eggs which wer...
