Abstract:
... Earlier research results have shown that the range of the ensemble flow simulations from a well-validated operational hydrologic model possesses a well-defined log-linear relationship to catchment area for which the ensembles are generated. The ensemble range is a function of both parametric and rainfall input uncertainty. In this paper the sensitivity of this scaling relationship for simulation u ...

Subject:
temporal variation; stream flow; watersheds; rain; watershed hydrology; runoff; hydrologic models
Abstract:
... Trying to determine annual stream flow only from annual rainfall and possibly annual potential evapotranspiration is a challenge that forces hydrologists to focus on very basic questions such as: Is stream flow of the current year only dependent on this year's rainfall? Does previous years' rainfall play a role? Is the role, if any, of antecedent rainfall confined to the transfer function, to the ...

Abstract:
... This paper presents a form of kernel function for karst aquifers derived from the time-invariant and non-anticipatory Volterra series. The shape of the kernel function depends on the current value of an index of antecedent recharge that is considered as an indicator of groundwater levels and vadose zone saturation. The proposed nonlinear form preserves specific characteristics of instantaneous uni ...

Aerobic conditions prevailed in winter, when temperatures were low, while anaerobic conditions were reached below the pond when temperatures exceeded 14 °C. In contrast to temperature changes, cyclic changes between saturated or unsaturated condition ...
