Eighteen low flow indicators are considered in the research of sixteen hydrological stations in the Juzna Morava river basin. The indicators are estimated by statistical analysis and grouped as hydrological and environmental indicators. A crosscorrelation between all indicators is assessed. Environmental flows at hydrologic stations are obtained by the GEP method. The environmental low flow indicators are transferred to two small ungauged basins by regression with physiographic characteristics. The adjustment of environmental flows at ungauged basins is performed according to locations of the donor stations in the hydrogeological regions of the studied area.

Tons River Basin

<p>Suitable and practicable best management practices (BMPs) are needed to develop effective and efficient watershed management under future climate change scenarios. Tons river basin is an agricultural-based watershed having a great significance to the States of Madhya Pradesh and Uttar Pradesh. Identification of critical erosion prone areas of the Tons River basin and implementation of BMPs for the future scenarios (2030-2050) using RCP 4.5 and RCP 8.5 scenarios is the main aim of this study. In this study, the Soil and Water Assessment Tool (SWAT) model was calibrated and validated for simulation of runoff and sediment yield using the Sequential Uncertainty Fitting (SUFI-2) technique. The values of coefficient of determination (R2), Nash–Sutcliffe efficiency (NSE), percent bias (PBIAS) and RMSE-observations standard deviation ratio (RSR) were 0.71, 0.70, -8.3 and 0.54 respectively during the calibration period whereas in validation the values were 0.72, 0.71, -3.9 and 0.56 respectively. Thus, the SWAT model can be employed in the Tons river basin of India for critical area prioritization and river basin planning and management under future scenarios.</p>

The Soil and Water Assessment Tool (SWAT) model was examined for its applicability in modeling stream-flow and nutrients (total nitrogen, TN and total phosphorus, TP) in Ashi River Basin, China covering an area of 3545 km2. This model was calibrated by using the observed data of monthly flow during 1996-2005 and nutrients (TN and TP) during 2006-2008, and validated by using the observed data of monthly flow during 2006-2010 and water quality during 2009-2010. For stream-flow, the monthly results of RE, R2 and ENS values reached 6.42%, 0.61 and 0.59 respectively for calibration period, whereas these were-12.83%, 0.69 and 0.67, respectively for validation period; for TN calibration, values of RE, R2 and ENS were-18.33%, 0.64 and 0.55 respectively, and for validation period they were-17.34%, 0.68 and 0.57 respectively; for TP calibration, values of RE, R2 and ENS were-4.32%, 0.61 and 0.56 respectively, and for validation period they were-18.02%, 0.67 and 0.58 respectively. Results show that SWAT has applicability in modeling stream-flow and nutrients (TN and TP) in cold and flat area.
