Simulation Of Surface runoff For Upper Tapi Subcatchment Area (Burhanpur Watershed) Using SWAT

Abstract

ABSTRACT:Water related activity that takes place in one part of a river basin may have consequence in the other part. Any plan related to inter basin transfer of water from a water surplus basin to a deficit basin has to take into account the water availability and demands under the present and future scenarios of water use. Watershed is a hydrologic unit where all stream exit from the common outlet. In the present study, Tapi subcatchment area (Burhanpur watershed) located in inter-state basin of Madhya Pradesh and Maharashtra, India, is selected for the estimation of surface runoff using SWAT model. The SWAT works in conjunction with Arc GIS 9.3. Various parameters Digital Elevation Model (DEM), slope derived from DEM, Landuse/Landcover (LULC) and NBSSLUP soil data and temporal data for temperature and precipitation was used as input for the model to predict runoff at the catchment outlet. The model was run from the year 1992 to 1997. The performance of the model in terms of simulated runoff was evaluated using statistical method and compared simulated monthly flow with the observed monthly flow values from 1992 to 1996 to a significant extent. The coefficient of determination (R 2 ) for the monthly runoff values for 1992 to 1996 was observed to be 0.82, 0.68, 0.92, 0.69.

Estimation of Surface Runoff to Bahr AL-Najaf

“…Another study evaluated performance for modeling the precipitations and rainfall in the Watershed of Laou; they showed the feasibility of implementing the SWAT model was enabled to simplify the representation of the flows on the watershed (Aqnouy, et al, 2019). Other Studies involved the variation in surface parameters (e.g., Topography, soil, and land cover) that affected the linkage between rainfall and surface water in watersheds (Shivhare, et al, 2014). Conducted a study to estimate the groundwater vulnerability in the Bahr Al-Najaf area, the middle of Iraq.…”

Evaluation of multisite performance of SWAT model in the Gomti River Basin, India

“…Saha et al (2013) carried out "Streamflow modeling in a fluctuant climate using SWAT in Yass River catchment," to predict the flow and compared with the observed data in southeastern Australia. Shivhare et al (2014) examined the performance of "Simulation of Surface Runoff for Upper Tapi Sub-basin Area (Burhanpur Watershed) Using SWAT"; from 1992 to 1997. Sisay et al (2017) examined the "Hydrological modelling of ungauged urban watershed using SWAT model" in Vadodara city of Gujarat.…”

Hydrological model for Hemren dam reservoir catchment area at the middle River Diyala reach in Iraq using ArcSWAT model

“…Out of these models, the Soil and Water Assessment Tool (SWAT) is a continuous daily step, long period, physically based parameter, and distributed hydrologic model has been used widely to simulate agricultural watersheds management practices as in Moriasi et al (2011), help to evaluate the climate change impacts as in Singh and Gosain (2011), identify water quality in watersheds as in Boithias et al (2011) and Oeurng et al (2010), and assess the surface, subsurface flow, and sediment yield transfer in various watersheds with varying soils as in Arnold et al (2012) and Gassman et al (2014). Researchers have applied Arc-SWAT model in several wet and semi-arid areas around the world, such as southern Australia as in Shrestha et al (2016), South Asia as in Shivhare et al (2014), North and southeast Africa as in Baker and Miller (2013), Bouraoui et al (2005) and Sellami et al (2016), and in the Mediterranean coastal basin in Spain as in Molina-Navarro et al (2014). Several researchers have studied the water balance of the dam's reservoir watershed using SWAT model as in Neitsch et al (2002Neitsch et al ( , 2011, China as in Wang and Xia (2010) and Pakistan as in Ghoraba (2015).…”
