Characterizing the response of a catchment to an extreme rainfall event using hydrometric and isotopic data
[1] In this study we investigate an event-scale transit time distribution (TTD) for a catchment located in the Santa Catalina Mountains northeast of downtown Tucson, Arizona, USA, during a series of extreme rainfall events. Traditionally, TTD studies look at the long time response of a catchment to an input variation in tracer concentration. Few studies have determined the TTD at the scale of a...
متن کاملEstimating Height runoff by using curve number method and Arc- CN Runoff tool in Afjeh Catchment
In Iran, there is a general risk of runoff and flood, and since this country has a dry to semi-arid climate, its predominant rainfall is not evenly distributed in terms of time and place. Routine runoff at the earth's surface can lead to risks such as groundwater abatement, social issues such as population migration, erosion and loss of soil fertility, sedimentation in reservoirs and water q...
متن کاملCharacterisation of Acid Mine Drainage Using a Combination of Hydrometric, Chemical and Isotopic Analyses, Mary Murphy Mine, Colorado
The legacy of mining continues to affect stream water quality throughout the western United States. Traditional remediation, involving treatment of acid mine drainage from portals, is not feasible for the thousands of abandoned mines in the West as it is difficult and expensive. Thus, the development of new methods to address acid mine drainage is critical. The purpose of this study was two fol...
متن کاملSimulation 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...
متن کاملEphemeral and intermittent runoff generation processes in a low relief, highly weathered catchment
Most field-based approaches that address runoff generation questions have been conducted in steep landscapes with shallow soils. Runoff generation processes in low relief landscapes with deep soils remain less understood. We addressed this by characterizing dominant runoff generating flow paths by monitoring the timing and magnitude of precipitation, runoff, shallow soil moisture, and shallow a...
