    Assessing the Impacts of Vented Dam Land Submergence and Storage Capacity for Water Resources Management
    (Springer Science and Business Media Deutschland GmbH, 2024) Mahima, N.; Pai, A.; Umesh, P.
    Water plays an important role in sustaining life on earth hence it is necessary to store water and increase the ground water table. Due to the increase in population, the demand for water has also risen over a period of time. The area with sufficient rainfall is also facing scarcity of water due to improper water storage management. In order to overcome the scarcity of water, vented dams are constructed to harvest the water. The present study is attempted for two vented dams that are at Nethravathi River and Papanashini River. In order to increase the storage of water in the reservoir the height of the dam gate is increased by 2 m on the existing height. Due to which there is submergence of land and there is increase in area of storage. Bathymetry survey is carried out to determine the depth of water stored and volume is estimated. The water stored can be used for irrigation, surrounding agricultural purposes. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

    Modelling and Mitigation of Urban Floods: A Case Study in Mangalore
    (Springer Science and Business Media Deutschland GmbH, 2024) Pai, A.; Mahima, N.; Umesh, P.; Abhijith, P.A.
    Urban flooding is a growing concern in many cities around the world, particularly in areas that are prone to heavy rains. In this study, we focused on a small drain catchment in an urban area in Mangalore and simulated the actual conditions of the drain to replicate what is found in the field. An extreme rain event was input into the PCSWMM software to find out the flooding conditions, which were then calibrated based on the flooding that had taken place during this particular rain event. We then redesigned the drains at the required portions to make the flooding conditions zero for the extreme rain event. This work is a small part of a larger project that aims to explore various techniques to reduce stormwater flooding in urban areas using structural, non-structural, and lid techniques. The results of this study provide insights into the effectiveness of this approach in mitigating urban flooding, and can serve as a basis for further research in this area. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
