Oxygen 18 fractionation during snowmelt: Implications for spring flood hydrograph separation
[1] Isotopic hydrograph separation (IHS) to define sources of event and preevent water during hydrological episodes has greatly improved the understanding of water, solute, and contaminant transport to streams during recent decades. However, the large variation in snowmelt isotopic composition, caused by fractionation during melting, has impeded an accurate separation of streamflow during sprin...
متن کاملHow isotopic fractionation of snowmelt affects hydrograph separation
We present the isotopic composition of meltwater samples from four seasonal snowpacks: a warm, maritime snowpack in California; a temperate continental snowpack in Vermont; a cold continental snowpack in Colorado; and an Arctic snowpack in Alaska. Despite the very different climate conditions the υ18O of meltwater from all four snowpacks increased as melting progressed. This trend is consistent...
متن کاملFlood Hydrograph Estimation Using Watershed Bounded Network Model
Storage routing models are becoming more widely accepted for flood hydrograph synthesis. The network models represent a considerable advance in this direction even though these models are based on many assumptions and empirical relationships. Watershed Bounded Network Model (WBNM) is one such model. This model maintains a good relationship between the hydrological and geomorphological propertie...
متن کاملFlood Hydrograph Simulation with Uncertainty in Rainfall - Runoff Parameters
Flood hydrograph simulation is affected by uncertainty in Rainfall – Runoff )RR( parameters. Uncertainty of RR parameters in Gharasoo catchment, part of the great Karkheh river basin, is evaluated by Monte–Carlo (MC) approach. A conceptual-distributed model, called ModClark, was used for basin simulation, in which the basin’s hydrograph was determined using the superposition of runoff generated...
