Timely and reliable flood forecasting is critical for flood warning delivery and emergency response. As core components of an operational forecasting system, hydrological models are typically calibrated using streamflow measurements to minimize parameter uncertainties. The rapid development of earth observation techniques provides opportunities to obtain soil moisture information. As catchment ...

The Soil and Water Assessment Tool (SWAT) model was used to assess the implications of long-term climate trends for the hydroclimatology of the Reynolds Creek Experimental Watershed (RCEW) in the Owyhee Mountains, Idaho of the Intermountain West over a 40year period (1967-2006). Calibration and validation of the macroscale hydrology model in this highly monitored watershed is key to address the...

Low resolution meteorological satellite and high resolution earth resources satellite data have been used to map snowcovered area over the upper Indus River and the Wind River Mountains of Wyoming, respectively. For the Indus River early Spring snowcovered area was extracted and related to April through June streamflow from 1967-1971 using a regression equation (r = 0.91). Prediction of the Apr...

Objective: Currently, the evaluation of baseflow components have been of a worldwide concern due to the influential role of streamflow (base flow and direct flow)in agriculture, water sources management as well as supplying the potable water. Direct and field measurement of baseflow is not practicable especially in large areas with statistics deficiencies. Also, this would not be economically e...

In this study,...

A Hierarchal Bayesian model is presented for one season-ahead forecasts of summer rainfall and streamflow using exogenous climate variables for east central China. The model provides estimates of the posterior forecasted probability distribution for 12 rainfall and 2 streamflow stations considering parameter uncertainty, and cross-site correlation. The model has a multi-level structure with reg...

Received 6 January 2011 Accepted 14 January 2011 One of the most significant consequences of climate warming is the likely change in streamflow as a result of warming air temperatures. Hydrologists have responded to the challenge of understanding these effects. Many recent studies quantify historical trends in streamflow and usually attribute these trends to climate warming, via altered evapotr...

Intermittent streamflow is a common occurrence in permeable catchments, especially where there are pumped abstractions to water supply. Many rainfall-runoff models are not formulated so as to represent ephemeral streamflow behaviour or to allow for the possibility of negative recharge arising from groundwater pumping. A groundwater model component is formulated here for use in extending existin...

ISSN 2277 5056 | © 2012 Bonfring Abstract--Evaluation of stream flow network in any geographical region has utmost importance for planning, design and management of water resources so as to reduce chances of project failure and also to minimize the economic risk. Setting up and maintaining a streamflow network is an evolutionary process, which is need to be reviewed and upgraded periodically to...

A sample-data system discretization of the continuous Kalinin–Milyukov–Nash cascade is performed in a state-space analysis framework allowing for stream–aquifer interactions that include bank storage during flood events and groundwater discharge to the stream under low-flow conditions. These interactions generally result in faster attenuation of propagating flood waves and in elevated streamflo...
