Abstract:

Most of the individuals in residential areas experience the problem of running out of water and overflow tanks. It becomes more difficult for the consumer to gauge the amount of water in the tank. When the pump is ON, the user will not realize that the water tank is filled, which may result in an overflow. Auto water pump switch is used to troubleshoot problems with the water tank. The consumer can use this technology to fill an empty tank without having to take any effort. When the tank is empty, the system automatically turns ON, and when the tank is filled, it automatically turns OFF. Water is not wasted with this technique

Abstract:

The increasing frequency of extreme storm events has implications for the operation of sewer systems, storm water, flood control monitoring and tide level variations. Accurate and continuous monitor water level monitoring is demanded in different environments. Piezoelectric sensors are widely used for water level monitoring and work submerged in waters subject to the presence of solid particles, biological fouling and saltwater oxidation. This work aimed to develop a simple, low-cost methodology to protect sensors over long-term deployment. The results show that simple actions, costing less than 2 EUR, can protect and extend the lifecycle of equipment worth over 2000 EUR, ensuring continuous monitoring and maintaining quality measurements.

Abstract:

The real-time monitoring of water level is a key element for the security and automation of shiplock. To meet the requirement of real time measurement and information releasing of multipoint water level for a shiplock station, a multi-channel water level monitoring and SMS interaction system based on high-performance MCU W77E58 is designed. Pressure water level sensors are used to acquire multipoint real-time water levels at upstream, downstream, lock chamber points. The water level information is processed by MCU and transmitted to the remote IPC through the RS485 bus. IPC interface is designed basing on VB6.0. It completes the bi-directional interaction of water level information to cell phone users with GSM module by sending short messages. Site operation shows that overall scheme of the system is reasonable, hardware and software works well and running costs is relatively low. The system fully meets the requirements of shiplock and is worth popularizing and application.

Abstract:

The water quality of the Szarvas-Békésszentandrás Dead Körös is generally meso-eutrophic, and meso-saprobic. However, particularlyunder higher temperature conditions, the water body may change toward the eutrophic state, even algal blooms could be observedpreviously.The present measurements were conducted during a two week period, twice a day. Three water samples were taken horizontally, fromthe surface, bottom and the middle of the water body. The samples were examined in situ. The oxygen content, the temperature, the pH andthe conductivity were measured by potentiometric methods.Increasing pH was detected in correlation to the temperature, which indicated a rising photosynthetic activity. Also, the O2concentration showed high variations, especially, when the fresh water supply from the river was stopped, due to a small flood in the riverKörös.These results indicate the increasing eutrophication processes in the deadarm, and the high load and instability of the ecosystem.

Abstract:

In this paper, we present a system for measuring and monitoring of groundwater level. Level of groundwater is needed to create hydrodynamic models of inland excess water, which causes significant environmental and economic problem worldwide, because large parts of the flat terrain can be covered by inland excess water. On areas of interest, continuous measurement of groundwater level on several measurement points over long periods of time (several years) is needed as input data for hydrodynamic models. Measurements of groundwater level are made by acoustic system, which measure time of travel of sound to and from level of water inside wells. Every measurement point is equipped with GPRS transceiver, which sends data over GSM network to server connected to internet. Software on server collects and saves measured data in databases in adequate data format. Prototype of system is made, and hardware and software realization, communicating network and measurement results are presented.

Abstract:

This study presents a developed ultrasonic water level detection (UWLD) system with an energy-efficient design and dual-target monitoring. The water level monitoring system with a non-contact sensor is one of the suitable methods since it is not directly exposed to water. In addition, a web-based monitoring system using a cloud computing platform is a well-known technique to provide real-time water level monitoring. However, the long-term stable operation of remotely communicating units is an issue for real-time water level monitoring. Therefore, this paper proposes a UWLD unit using a low-power consumption design for renewable energy harvesting (e.g., solar) by controlling the unit with dual microcontrollers (MCUs) to improve the energy efficiency of the system. In addition, dual targeting to the pavement and streamside is uniquely designed to monitor both the urban inundation and stream overflow. The real-time water level monitoring data obtained from the proposed UWLD system is analyzed with water level changing rate (WLCR) and water level index. The quantified WLCR and water level index with various sampling rates present a different sensitivity to heavy rain.

Abstract:

The biological monitoring of water saprobity and trophic degree primarily involves the study of qualitative and quantitative composition of organisms present in the water. Although relatively satisfactory as an indicator of the water's organic load, the counting of bacteria is often an unreliable parameter. Due to their polyenzymatic nature, which enables flexible adaptation to new and different physico-chemical conditions of their habitats, microorganisms respond quickly to trophic degree change, but faster by changing the level of their enzyme activity, than by changing the number of cells. On the basis of these findings, the enzyme activity of microbialaquatic biotopepopulations is suggested in recent literature as an additional indicator of the degree of organic load in the water. The results obtained by investigation of the phosphatase activity in samples from natural and artificial water accumulations and flowing waters in Vojvodina Province, having different eutrophic degree, suggest the measurement of the level of water enzyme activity as an additional biochemical indicator of saprobity degree. At the same time, on the basis of long--term measurement of the water phosphatase activity, compared to classical categorizations based on qualitative and quantitative composition of organisms present in the water, classification of surface freshwater s into quality categories according to the level of enzyme (phosphatase) activity of water is proposed.

Abstract:

Hydroponic is one of growing plant method without soil. It uses water as the planting media. As of this writing, hydroponic method is quite popular in Indonesia because it is more hygienic, more results, more environmentally friendly at a lower cost production. Hydroponic life depends on the nutrients in the water. One of the most important of the hydroponic method is pH level of the water. The standard of pH level which used to grow a plant is in the range of 5.5 to 6.5. To balance the standard of pH level, liquid for increasing and decreasing pH level are needed, but it is difficult to measure the pH level on the standard range while adding the water. Based on this problem, this project will develop an automated device for mixing pH up and pH down liquid so the level of pH will be keep in the desire range using pH sensor and Arduino microcontroller.

Abstract:

With the ever increasing growth in population water quality monitoring has become a critical issue in the recent years. Water quality monitoring is very important for aquaculture, waste water management, drinking water treatment, water distribution system, and other environmental applications. Recently numerous researchers have been initiated to build wireless system for water quality monitoring (WSWQM). The two fold objectives of WSWQM are (a) monitoring of water quality from a remote location with minimum supervision, and (b) initiating immediate corrective actions to maintain the required water quality standard. In this paper we present a system model for WSWQM. In this system we integrate a number of sensors, transmitters, receiver, myRIO microcontroller, and IEEE 802.11 Wi-Fi technology. The sensors generate water quality data including pH, conductivity, and temperature. The real-time data are then sent wirelessly to a local control unit for analyzing, recording, and displaying. The system is also able to send alarm messages automatically to a remote management center when water quality fails to meet the required standard. In order to ensure high accuracy and reliability we use industry standard sensors and instruments to implement this system.

Abstract:

Water is most profitable and valuable source since it is the fundamental need of all the individuals. Now a day we are facing many issues regarding water wastage and quality monitoring in tanks. This paper proposes a proficient method to water level and quality observing in the overhead tanks to lessen the present water wastage and give better water quality. The venture is about overhead tank checking framework that is we screen the level of water in the overhead tank and furthermore we decide nature of water. Firstly, we have the issue of filling the tanks which are situated far, and for this we have executed a little hypothesis that we put level sensors in the tank, that level sensors detect the water level in the tank and sends us message about water level in the tank. Also, the second preferred standpoint is that really, we utilize different quality parameter sensors like pH and turbidity sensors to screen the water quality in the tank. In light of level of water, we can choose how much measure of water is required for specific area and give adequate measure of water as opposed to squandering water. The Raspberry Pi B+ is utilized as core controller. The composed framework applies to an IOT module for getting to sensor information from center controller to cloud. The sensor information can be seen on cloud. At last information will be assembled and through Wi-Fi information can be seen on versatile device through android app. Based on data in the app workers will be sent to clean the tank This proposed framework is a minimal effort, wireless, multi-sensor arrange for exact water monitoring in tanks.

Abstract:

Najran city faces the flood situation every year due to intensive rain and climatic disturbances. Flooding also causes loss of money, along with loss of life and property and the destruction of agriculture and livestock. Thus, this project proposes a conceptual framework with three main phases: monitoring the water level inside the dam and level in water stream before and after the dam, controlling the opening and closing of the dam gate and measuring the water pressure at the dam barrier. In the case of high water level dam is monitored through water sensors placed at the top of the dam and then these sensors give a reference to the stepper motor and the flow of the stepper motor is controlled by the dam gate. The experimental results shows that the proposed system has the capability to reliably tackle the flood water. It can accurately measure the water level and control the gate of dam as soon as the level of the water reaches to danger level and water pressure at the barrier is measured by the sensor. The developed real-time monitoring system in Najran dam will help authorities to take preventive actions to deal with flood disaster.

Abstract:

Operating conditions for using oiled sodocalcic glass wool (Saint Gobain R. 725) to concentrate enteroviruses in 100 to 1000 liters samples were determined. These filters recovered from 62 to 75% of several enteroviruses (laboratory strains or field isolates) and rotavirus SA11 that were added to tap water. The technique permitted the recovery of 62% and 57% of poliovirus added respectively to river water and treated waste water. The results of a 44 months survey of the Seine and Mame river waters are reported. Being efficient at ambient pH, the use of glass wool may permit continuous virological monitoring of water samples.

Abstract:

Issues affecting the utility and accuracy of water level measurements for storm surge are addressed. Vertical datum control (including land elevation measurements), water level sensor survivability, and sensor placement are critical to obtaining useful information on storm surge. Hurricane Dennis in 2005 provides an example of how water level measurements are used to evaluate and improve storm surge prediction models. A water level gauge operated by the University of South Florida Coastal Ocean Monitoring and Prediction System (COMPS) was the only site to capture time history of the maximum surge that occurred in Apalachee Bay, Florida, leading to improvements in the storm surge prediction model. A more dense network of water level gauges, as a component of the U.S. Integrated Ocean Observing System, will enable a more efficient response to and mitigation of future storm surge events.

Abstract:

Technology has advanced to the point that it can assist people in their daily lives. Human beings may benefit from this development in a variety of ways. Progress in river water monitoring is also one of them. There are many advantages in improving the river water monitoring system. The objective of this project is to develop an automated system for monitoring river water levels and quality with push notification features. Internet of Things (IoT) was implemented in this research by using NodeMCU as a microcontroller to connect both ultrasonic sensors and pH sensors to the Internet. An ultrasonic sensor is used to read the water level, and a pH sensor is used to read the water pH values. The results show the successful output from all of 10 time attempts to obtain more accurate test results. The results will be averaged to be analysed and concluded from the test. All the tests include testing for the accuracy of the ultrasonic sensor, the accuracy of the pH sensor, and the performance of the internet connection using integrated Wi-Fi module in NodeMCU microcontroller. The system test also shows that it performs perfectly with the requirement needed to send the real-time status of the water level, water quality and an alert to the user using the Telegram Bot API. This research can help to increase the level of awareness of the river water monitoring system. This research was done by looking at people's problems in the vicinity of the river area by producing a system tool that helps to monitor the river water in real-time status.

Abstract:

Flooding is one of the most frequent and costly natural disasters affecting mankind. However, implementing Internet of Things (IoT) technology to monitor river behavior may help mitigate or prevent future disasters. This article outlines the hardware development of an IoT system (RiverCore) and defines an application scenario in a specific hydrological region of the state of Colima (Mexico), highlighting the characteristics of data acquisition and data processing used. Both fixed position and moving drifter node systems are described along with web-based data acquisition platform developments integrated with IoT techniques to retrieve data through 3G cellular networks. The developed architecture uses the Message Queuing Telemetry Transport (MQTT) protocol, along with encryption and security mechanisms, to send real-time data packages from fixed nodes to a server that stores retrieved data in a non-relational database. From this, data can be accessed and displayed through different customizable queries and graphical representations, allowing future use in flood analysis and prediction systems. All of these features are presented along with graphical evidence of the deployment of the different devices and of several cellular communication and on-site data acquisition tests.
