Population growth and unequal distribution, poor irrigation systems, rapid urbanization/ industrialization, large-scale deforestation, droughts, and inefficient land use practises contribute to groundwater depletion.As a result, the need for water for agriculture, domestic, and industry soars. The study identifies viable zones in Visakhapatnam's emerging metropolitan metropolis by utilising the Analytical Hierarchy Process (AHP) approach with remote sensing data in ArcGIS software. Thematic layers were created by taking remote sensing data into consideration (drainage density, soil, lineament density, land use land cover, geomorphology, rainfall, slope, and geology). The method is employed to determine the weights of distinct thematic layers by obtaining the normalised weight from a pairwise matrix.To emphasize the groundwater potential zones and create a map with different zones specified, the weights and ranks extrapolated from the AHP approach have been made available in the weighted index overlay analysis tool in ArcGIS.Groundwater availability and recharge are significantly high in the good zone of the present study's four classifications of good, moderate, low, and very low. The groundwater status, potential locations for water extraction, and best practises for groundwater recharging may all be determined with the use of the acquired information from the indication map.

Changes during 20 years period are studied at each station. Significant morphological changes along the coastline are observed in the study. The study indicates that gradual erosion is observed at Museum North and South, R K Beach, Rushikonda and Mangamaripeta.

This paper presents results obtained from a physical model study to understand the transmission and reflection characteristics of LCB as a defence structure in front of a vertical seawall. The paper mainly focuses on

The main aim of the tests was to know the effect of crest elevation of the offshore low-crested breakwater as a rehabilitation structure for the existing damaged shore protection structures. In this study five relative breakwater heights are used and associated flow evolution was analyzed. With the sections proposed in this study, it is possible to achieve considerable reduction of wave force on the seawall. Modification factor is proposed to estimate the shoreward force on the seawall defenced by low-crested breakwater.

The relative wave height, (Hi/d) varied from 0.114 to 0.429 and the porosity was kept constant with 12%. The force ratios were found reducing with increase of Hi/d. It is estimated that on an average, the reduction

A two-dimensional finite-element model is employed to study the hydrodynamic performance of the submerged breakwater under the action of regular and random waves. The numerical prediction has been supported with experimental measurements. The wave forces and wave run-up on the vertical wall were measured for different breakwater configurations. The applicability of linear theoretical model in the prediction of wave forces on the wall by a submerged breakwater has been discussed.

A series of physical model tests were carried out in a wave flume to examine the performance of the defence structure in reducing the wave pressures over the seawall/caisson. The influence of the pool length and relative submergence depths on wave pressures was also investigated. Influence of the pool length on reduction of pressure ratios is observed to be small for two ranges studied. Average shoreward pressure ratio is more for relative barrier height, h/d=0.83 for the pool lengths chosen in the experimental investigation.
