Abstract: This study carried out a numerical modelling of storm surges for historical tropical cyclones that crossed the Chennai coat, the northern part of the coastline of Tamil Nadu, India. An extreme value analysis was made based on the peaks-over threshold 9POT) method to calculate extreme storm surge estimates for different return periods. The area's bathymetry was generated from the National Institute of Oceanography (NIO) sea-floor data derived from ETOP05(the earth's surface that integrates land topography and ocean bathymetry).Historical storm tracks in the vicinity of the study area were selected from the database. These storm tracks were used to generate temporally and spatially varying wind and pressure fields using the Holland method. Cyclones considered for the simulations are from a 35-year period, ranging from 1977 to 2012.Cyclones of significant intensity that occurred in the vicinity of Chennai were selected for modelling. The Delft 3D modelling software was used for the analysis .The domain considered for the study was generated on a rectilinear grid of size 540 x 670 km covering the coastline from Nagapattinam in Tamil Nadu to Diviseema in Andhra Pradesh with 1.35 km x 1.65 km as the size of each grid cell. The water level calculated by the Delft3D-FLOW module by solving the shallow water equations (SWEs) was extracted from the model over the entire domain at constant intervals and was monitored. The maximum surge in the water level at the Chennai coast was reported as the storm surge value for each cyclone. Results showed that Chennai is highly vulnerable to cyclones. A one-in-a-100-year cyclone can produce a storm surge of 1.0 m, which can pose severe hazards to the city, since the topography is very low. This study will assist officials in preparing for a disaster of this enormity.

Abstract: As the wireless sensor networks (WSNs) continue to evolve, it becomes more and more significant in our day-to-day lives. By using WSN technology and the basic principles of the Internet, designing an agricultural monitoring system (AMS) becomes important for improving agriculture in India. The AMS is low-power conservation with high precision, which can realize remote, real-time monitoring for unattended farmlands. WSNs are a promising approach used in AMS, but finding an optimal route discovery is more problematic due to dynamicity, heterogeneity, resource scarcity, and so on. The proposed optimized QoS-based multipath routing protocol (OQoS-MRP) for the WSNs in AMS is used to find near-optimal multi-hop communication path from sink to sensors for selecting the next hop neighbour nodes. The best case paths selection procedure is used for transferring data to sink. According to the QoS metrics, the performance of this communication protocol is evaluated and compared with the other existing protocols, namely, EE-LEACH and MRBCH. The simulation result shows that OQoS-MRP for the AMS achieves prominent data communication with reasonable energy conservation. It also reduces transmission delay and communication overhead on the basis of ensuring the outcome of the entire network.

Subject: Water complexities due potential of hydrogen (pH) in Lake waters of Kashmir Valley
Keywords: Kashmir water lakes, Ligands, Metal ions, pH-metric studies, Glycine and cysteine
Abstract: The stability of heavy metal complexes cannot be accounted by a single factor, each is considered separately in terms of ligands or vice-versa, hence revealing that he stability constants show a large variation in values. The stability constants of heavy-metal complexes in the solution phase are generally considered as being stable or unstable, depending on the strength of the bond between heavy metal ion and ligands. The stability of a complex is very often expressed in terms of the stability constant, which is used to describe the equilibrium behavior of metal complexes. This paper studies the interacting behavior of the prototype heavy-metal ions and ligands as fund in the water bodies in the lake waters of the Kashmir Valley.

Subject: 0.75 hp Solar water pumping systems as an irrigation option for small and marginal farmers
Keywords: Solar water pumping systems, Sprinklers, irrigation, Crops, Remote villages
Abstract: Only 36 % of the total cropped ae in India falls under irrigated land and the rest 64% is rainfed. According to the 2010/11 Cenus [1], out of 85% of the total farmer families, more than 67% belong to the marginal farmers and 18% to small farmers. Many times, the land is fragmented into 2-3 different patches. Irrigation is an important aspect in agriculture to improve agricultural productivity and reduced dependence on rains. Irrigation can be powered either by electricity or diesel, wherein the operational cost of diesel-based irrigation is much higher and also not very environmentally friendly. In this context, the introduction of solar-powered water pumping system is a good option in the remote areas where grid supply is either intermittent or not available at all. This article discusses the initiative where solar water pumps for irrigation were tested in small and marginal farms in Golaghat District.

Abstract: The 2030 Agenda for sustainable development, with its ambitious 17 goals and 169 targets, aims to end poverty, protect the planet, and ensure prosperity for all. However, the success of these goals and targets would depend on developing the rural areas where most of the world's poor live.
More resources would need to be allocated for investment in rural areas, not just because that is where most of the poor live but also because these areas have a great potential for economic development (SOFA 2017). The rural population worldwide is vulnerable to livelihood shocks and climate variability.
