Standardized Runoff Index (SRI), as one of the well-known hydrological drought indices, may contain uncertainties caused by employment distribution function, time scale, and record length statistical data. In this study, uncertainty in SRI estimation monthly discharge data 30- 49-year lengths from Minab Dam watershed, south Iran, was investigated. Four probability functions (Gamma, Weibull, Log...

Two methods have been developed for identifying locations in watersheds where vegetative buffers would yield greater benefit for reducing agricultural nonpoint source pollution. The methods were compared and contrasted to evaluate the degree to which they identified the same or different locations within a watershed. The two methods included the terrain analysis-based topographic index, TI, (Qi...
