Global Water Resources with Special Reference to India
Abstract: The world’s water resources face formidable threats. More than a billion people currently live in water-scarce regions, and as many as 3.5 billion could experience water scarcity by 2025. Increasing pollution degrades freshwater and coastal aquatic ecosystems. And climate change is poised to shift precipitation patterns and speed glacial melt, altering water supplies and intensifying floods and drought. 97% of the water on the Earth is salt water and only …

Simulation of Sediment Deposit and Maintenance Requirements for Sani- Abacha Road Culvert, Rivers State, Nigeria
Abstract: Empirical model of sediment yield equation was applied to develop the sediment deposit monitoring equation of the Sani-Abacha road culvert. The culverts were selected based on field observation of continuous overflow, road overtopping and channel contraction in the course of heavy storm due to sediment built up within and inside the culvert barrel. The result of the assessment shows that the way sediment load varies with discharge is consistent and …

Evaluation of Hydraulic Performance: A Case Study of Etana Small Scale Irrigation Scheme: Wolaita Zone, Ethiopia
Abstract: The conventional furrow irrigation system is inherently inefficient in wolaita zone, while the suboptimal management and operation (inflow discharge and cutoff time) are considered as one of the main reasons for satisfactory hydraulic performance. Addressing these issues, the furrow irrigation system which is only practiced in the study area was evaluated on three fields under routine farmer management in wolaita zone. The study consisted of field experiments and simulation modeling. …

Treatment of Dairy Wastewater Using Constructed Wetland
Abstract: Naturally existing wetlands have been used for dumping various types of wastewaters and have been promised to dispose of these wastewaters. As a matter of fact, in some areas, natural wetlands still serve this purpose solely and are nothing more than dumping sites. However, extensive research suggested the use of Wetlands for Treatment purposes. Understanding the dynamics of the processes in natural wetlands leads to the use of those processes …

Detection of Stego from Motion Vector Patterns Using Steganalysis
Abstract: The ultimate goal of this paper is to detect a stego (encrypted message) in the compressed video using various steganalysis techniques. Although there are many steganalysis methods, in this paper we concern more about the detection accuracy so that no stego will be escaped. To capture all the deviations in the video we use the filters of higher orders. The temporal dependency of the motion vector planes is also considered …

Design and Implementation of Trans-Z-Source Inverter
Abstract: ABSTRACT This paper presents the impedance-source (Z-source) inverters concept to the transformer-based Z-source (trans-Z- source) inverters. The original Z-source inverter (ZSI) contains an impedance network of two inductors and two capacitors connected in a unique arrangement to interface the dc source and the inverter. It has buck and boost function that cannot be achieved by traditional voltage-source inverters and current- source inverters. In the proposed trans-Z-source inverter, the impedance network …
