Derivative Discharge and Runoff Volume Simulation from Different Time Steps with a Hydrologic Simulator

Simulation of Runoff Quality in Sub-catchment of Karkheh Watershed Using a Field Rain Simulator

In this study, the effects of three land use categories on runoff quality was investigated using a rainfall simulator, in six sub-catchments in Kakasharaf watershed in Lorestan province. In total, 39 instances of artificial rain with a duration 30 min were created and the amount of phosphorus and potassium in the resulting runoff was measured on three land uses. The results showed that the aver...

Hydrologic Evaluation of Established Rain Gardens in Lincoln, Nebraska Using a Storm Runoff Simulator

Increased urbanization has resulted in water quality and flooding problems for many receiving waters in the United States. Bioretention, or rain gardens, is one of the most widely popular and effective best management practices in low impact development (LID), which strives to return a watershed to a predevelopment hydrologic regime. Many studies have evaluated large bioretention cells in resea...

The efficiency of Artificial Neural Network, Neuro-Fuzzy and Multivariate Regression models for runoff and erosion simulation using rainfall simulator

1- INTRODUCTION According to the complexity of environmental factors related to erosion and runoff, correct simulation of these variables find importance under rain intensity domain of watershed areas.  Although modeling of erosion and runoff by Artificial Neural Network and Neuro-Fuzzy based on rainfall-runoff and discharge-sediment models were widely applied by researchers, scrutinizing Arti...

Concentration-discharge relationships in runoff from a steep, unchanneled catchment

The observation that “old” water dominates storm runoff suggests that release of low-solute water from soils rather than rainwater must cause storm runoff dilution. This inference is supported by sprinkling experiments in an 860-m catchment in the Oregon Coast Range, in which .200 mm of both high and low ionic strength precipitation produced similar concentration-discharge trends. Rainwater che...
