ANNOUNCEMENTS
According to the study's findings, an examination of morphometric characteristics with the support of a geographic information system(GIS) would be an appropriate method of describing the basin's hydrological response behavior.
Remote sensing and satellite data is becoming increasingly popular for morphometric studies of basins because it is cost effective, time saving, and accurate, making it a great alternative to conventional techniques of study. The DEM and drainage network were built from SRTM data from the Shuttle Radar Topography Mission (SRTM), which has a resolution of 30 meters. The Shuttle Radar Topography Mission's DEM data was used to construct this drainage network and density map.
To achieve the study's aims, the Penganga basin, a tributary of the Godavari River, was selected for extensive morphometric investigation. The Penganga basin, a river basin that flows across the southern Indian state of Andhra Pradesh, is home to lakhs of fish. Stream order analysis may be used to figure out factors like drainage density, stream order, stream length, bifurcation ratio, stream frequency, form factor, and circulatory ratio, among other factors. The drainage zone of the basin encompasses an area of about 23,898 kilometers square and features a drainage pattern that varies in character from sub dendritic to dendritic. When drainage density is considered, the region under examination is classified as a seventh order basin, with an average value of 0.8. It is possible to tell whether a stream is in its late youth stage of geomorphic growth by looking at the length ratio as it moves from one order to the next. As a result, GIS will be very useful in river basin evaluation, understanding the distribution of soil resources, basin prioritization, sediment load estimate, natural resource assessment, planning, and management at the river basin level.
