An integrated water balance model for assessing water scarcity in a data-sparse interfluve in Eastern India
An integrated water balance model for assessing water scarcity in a data-sparse interfluve in Eastern India
The objective of this study is to measure the balance of water demand versus water resource availability in an interfluve of West Bengal, India to support water resource planning, particularly of inter-basin transfers. Surface water availability was modelled using the Soil Conservation Service Curve Number (SCS-CN) model, whilst groundwater availability was modelled based on water level fluctuations and the rainfall infiltration method. Water use was modelled separately for the agricultural, industrial, and domestic sectors using a predominantly normative approach and water use to availability ratios calculated for different administrative areas within the interfluve. Overall, the approach suggested that the interfluve receives 327×106m3year?1 of excess water after satisfying these sectoral demands, but that the eastern part of the study area is in deficit. However, a sensitivity analysis carried on the approach to several assumptions in the model suggested changed circumstances would produce surplus/deficit ranging from -215×106m3year?1 to 435 ×106m3year?1 . The approach could have potential for localised water balance modelling in other Indian catchments

Abstract
The objective of this study is to measure the balance of water demand versus water resource availability in an interfluve of West Bengal, India to support water resource planning, particularly of inter-basin transfers. Surface water availability was modelled using the Soil Conservation Service Curve Number (SCS-CN) model, whilst groundwater availability was modelled based on water level fluctuations and the rainfall infiltration method. Water use was modelled separately for the agricultural, industrial, and domestic sectors using a predominantly normative approach and water use to availability ratios calculated for different administrative areas within the interfluve. Overall, the approach suggested that the interfluve receives 327×106m3year?1 of excess water after satisfying these sectoral demands, but that the eastern part of the study area is in deficit. However, a sensitivity analysis carried on the approach to several assumptions in the model suggested changed circumstances would produce surplus/deficit ranging from -215×106m3year?1 to 435 ×106m3year?1 . The approach could have potential for localised water balance modelling in other Indian catchments
