A Geo Spatial Approaches for Integrated Watershed Management (IWM) Case Study of Boni Mukundaraju Cheruvu, Andhra Pradesh, India

Abstract

Sustainable management of available water resources and judicious allocation to user needs within the ecosystem threshold can be achieved through Remote Sensing. To estimate the surface features with the help of change analysis which improves better resource management and decision-making in watershed hydrology assessment, interactions and relationships between human activities and natural phenomena are important. The present study on Geo-spatial approaches for Watershed management of Boni Mukundaraju cheruvu in Visakhapatnam district, Andhra Pradesh, India. From the study, we fixed it that the LULC of study area was classified into 5 major classes and 13 sub classes. During the study period from 2010-11 to 2020-21, it was observed that the wastelands in the catchment area were converted into water bodies seasonal and agricultural lands. It is also observed that the forest area was increased and majorly built up area was decreased from 2010-11 to 2020-21. The present study brings out the potential of geospatial techniques in LULC changes from 2010-11 to 2020-21, drainage patterns, Hydrological soil types (4types) and rainfall-runoffs from 1991-2021 (30 years) were described in detail.
