Impact of landuse/land cover change on Run-off in the catchment of a hydro power project
Applied Water Science, 2017Co-Authors: Deepak Khare, Diptendu Patra, Arun Mondal, Sananda KunduAbstract:The landuse/land cover change and rainfall have a significant influence on the hydrological response of the river basins. The Run-off characteristics are changing naturally due to reduction of initial abstraction that increases the Run-off volume. Therefore, it is necessary to quantify the changes in the Run-off characteristics of a catchment under the influence of changed landuse/land cover. Soil conservation service model has been used in the present study to analyse the impact of various landuse/land cover (past, present and future time period) change in the Run-off characteristics of a part of Narmada basin at the gauge discharge site of Mandaleswar in Madhya Pradesh, India. Calculated Run-off has been compared with the observed Run-off data for the study. The landuse/land cover maps of 1990, 2000 and 2009 have been prepared by digital classification method with proper accuracy using satellite imageries. The impact of the Run-off change on hydro power potential has been assessed in the study along with the estimation of the future changes in hydro power potential. Five types of conditions (+10, +5 %, average, −5, −10 % of average rainfall) have been applied with 90 and 75 % dependability status. The generated energy will be less in 90 % dependable flow in respect to the 75 % dependable flow. This work will be helpful for future planning related to establishment of hydropower setup.

Impact of landuse/land cover change on Run-off in a catchment of Narmada river in India
Applied Geomatics, 2015Co-Authors: Deepak Khare, Diptendu Patra, Arun Mondal, Sananda KunduAbstract:The landuse/land cover change has a significant influence on the hydrological response of a river basin. The Run-off characteristics are naturally changing due to reduction of initial abstraction that increases Run-off volume. Thus, it is necessary to quantify the changes in the Run-off characteristics of a catchment that occur due to changes in landuse/land cover. These changes can be sudden or continuous. Physically based conceptual models have developed to find out surface Run-off, and one of the models used in the present study is the Soil Conservation Service curve number (SCS-CN) model which has a broad range of applications. The present study is on the application of the SCS-CN model to analyse the impact of various landuse/land cover change in the Run-off characteristics of a catchment of Narmada basin in Madhya Pradesh, India. The study includes the preparation of a landuse/land cover map of different years from the satellite imageries, drainage network, and development of a database by using a geographic information system (GIS) and a Run-off generation with the model to estimate the impact of landuse change on Run-off.

quantitative assessment of climate change and human impacts on long term hydrologic response a case study in a sub basin of the yellow river china
International Journal of Climatology, 2010Co-Authors: Jiahu Wang, Yang Hong, Jonathan J Gourley, Pradeep Adhikari, Li Li, Fengge SuAbstract:In this study we developed an impact factor formula (IFF) to quantitatively attribute separately the impacts of climate change and local human activities on hydrological response (i.e. Run-off) in a sub-basin of Yellow River for the period 1950–2000. Using the daily climatic data, we first calibrated and verified the variable infiltration capacity (VIC) hydrological model to the baseline period 1955–1970. Then we developed the basin's natural Run-off for the following three decades (1971–2000) using the VIC model without considering local human impacts, as the VIC model is benchmarked by the 1960's hydrological regime. On the basis of observed precipitation, Run-off and reconstructed natural Run-off data from 1971 to 2000, we quantified their long-term trend, decadal and annual variations. Using daily climatic observations, we showed that the precipitation and Run-off have decreased from the baseline decade, the 1960s, indicating a drier hydrological regime for recent decades. We further applied the IFF to quantitatively attribute separately the impacts of reduced precipitation and increased temperatures from climate change and then of local human activities on hydrological Run-off response. It was found that climate change has a greater impact than human activities on the basin's Run-off for the three consecutive decades. The pCC (percentage change of Run-off due to climate change impact) is found to be 89% followed by 66% and 56% in 1970s, 1980s and 1990s, respectively. Over the decades, pHA (percentage change of Run-off due to human activities) has continuously increased from 11% to 44%. If the trend continues, in future, the pHA is going to outweigh pCC in this basin. This study provides a quantitative assessment methodology for water resources managers to understand the changing process of the hydrological cycle and attribute its causative factors in a sub-basin of the Yellow River.
