Sea Level Trend

Long-term water level changes have generally been estimated using tidal data. Tide gauges are common tools used to determine the continuous time series of relative water level. This paper presents an effort to interpret the water level from tidal data over Malaysian seas. There are 21 tide gauge stations involved and taken from Permanent Service for Mean Sea Level (PSMSL) with monthly averaged data from 1993 to 2011. The monthly tidal data is then converted to tidal sea level anomaly. For sea level trend analysis, robust fit regression is employed. Next, the sea levels were analysed based on the pattern of seasonal variation and extreme meteorological effects such as El-Nino and La-Nina.  In summary, the relative sea level trend in Malaysian seas is rising and varying from 2 to 6.5 mm/yr. This study offers valuable sea level information to be applied in wide range of climatology, related environmental issue such as flood and global warming in Malaysia.

Water level data sets acquired by ultrasonic sensors in stream-scale channels exhibit relatively large numbers of outliers that are off the measurement range between the ultrasonic sensor and water surface, as well as data dispersion of approximately 2 cm due to random errors such as water waves. Therefore, this study develops a data processing algorithm for outlier removal and smoothing for water level data measured by ultrasonic sensors to consider these characteristics. The outlier removal process includes an initial cutoff process to remove outliers out of the measurement range and an outlier detection process using modified Z-scores based on the median absolute deviation (MAD) of a robust estimator. In addition, an exponentially weighted moving average (EWMA) method is applied to smooth the processed data. Sensitivity analyses are performed for factors that are subjectively set by the user, including the window size for the MAD outlier detection stage, the rejection criterion for the modified Z-score outlier removal stage, and the smoothing constant for the EWMA smoothing stage, based on four different water level data sets acquired by ultrasonic sensors in stream-scale experiments.

ABSTRACT The slow handling of the flooding problem for people who live on riverbanks and densely populated areas in urban areas due to the lack of preliminary information obtained by the local community, causing huge losses both morally, materially and even causing fatalities. Based on these problems, a prototype monitoring system for flooding early detection was made with the aim that it can be used as a means of information whose data can be accessed through notifications in the form of short message services (SMS) in real time. In making this research, data collection was carried out in the form of water level data that had occurred at the location of the flood and then made the system design and implementation of that system by conducting trials in the field. This early flood detection system works by monitoring the water level using a level control system. This water level monitoring uses an ultrasonic sensor that is controlled using an arduino uno microcontroller. Data information about the water level is forwarded to the GSM module in the form of a notification message of SMS to the public. For the working of this prototype device in the design, the author uses an electrical power supply from renewable energy in the form of On Grid PLTS system. The results obtained from this research are for normal status the water level is at 5-50 cm, for alert status is 55-85 cm and for danger status is 90-100 cm.

In this study, the analysis of the extreme sea level was carried out by using 10 years (2007–2016) of hourly tide gauge data of Karachi port station along the Pakistan coast. Observations revealed that the magnitudes of the tides usually exceeded the storm surges at this station. The main observation for this duration and the subsequent analysis showed that in June 2007 a tropical Cyclone “Yemyin” hit the Pakistan coast. The joint probability method (JPM) and the annual maximum method (AMM) were used for statistical analysis to find out the return periods of different extreme sea levels. According to the achieved results, the AMM and JPM methods erre compatible with each other for the Karachi coast and remained well within the range of 95% confidence. For the JPM method, the highest astronomical tide (HAT) of the Karachi coast was considered as the threshold and the sea levels above it were considered extreme sea levels. The 10 annual observed sea level maxima, in the recent past, showed an increasing trend for extreme sea levels. In the study period, the increment rates of 3.6 mm/year and 2.1 mm/year were observed for mean sea level and extreme sea level, respectively, along the Karachi coast. Tidal analysis, for the Karachi tide gauge data, showed less dependency of the extreme sea levels on the non-tidal residuals. By applying the Merrifield criteria of mean annual maximum water level ratio, it was found that the Karachi coast was tidally dominated and the non-tidal residual contribution was just 10%. The examination of the highest water level event (13 June 2014) during the study period, further favored the tidal dominance as compared to the non-tidal component along the Karachi coast.

AbstractRetreat of calving glaciers worldwide has contributed substantially to sea-level rise in recent decades. Mass loss by calving contributes significantly to the uncertainty of sea-level rise projections. At Bowdoin Glacier, Northwest Greenland, most calving occurs by a few large events resulting from kilometre-scale fractures forming parallel to the calving front. High-resolution terrestrial radar interferometry data of such an event reveal that crevasse opening is fastest at low tide and accelerates during the final 36 h before calving. Using the ice flow model Elmer/Ice, we identify the crevasse water level as a key driver of modelled opening rates. Sea water-level variations in the range of local tidal amplitude (1 m) can reproduce observed opening rate fluctuations, provided crevasse water level is at least 4 m above the low-tide sea level. The accelerated opening rates within the final 36 h before calving can be modelled by additional meltwater input into the crevasse, enhanced ice cliff undercutting by submarine melt, ice damage increase due to tidal cyclic fatigue, crevasse deepening or a combination of these processes. Our results highlight the influence of surface meltwater and tides on crevasse opening leading to major calving events at grounded tidewater glaciers such as Bowdoin.

Railway Crossing

Railway is the most prominent and most economical way of transport. Majority of people depend on railways for transportation. Rail modes are most commonly used and very effective mode of commuting and goods carriage over long, short distances. In this paper, we are preparing a system in order to prevent the disasters which happen due to unmanned level crossing in the railways. For this system, Arduino Uno is used as the platform with ATMEGA16U2 as the microcontroller. In order to detect the train as well as the obstacles ultra-sonic sensors are used. When the train approaches the unmanned zone, ultrasonic sensor will detect the arrival of train which is kept 2 KM away from the railway crossing zone. The input of ultrasonic sensor is sent to Arduino Uno to activate the railway gates operated by DC motors. These gates are controlled or driven by motor driver circuit. If any obstacles are detected on the track can also be detected by the ultrasonic sensors which are kept at the gate and it will alert the train, with the help of led signal. Due to this led signal, the train will slow down the speed mechanically or even the train can stop if it's necessary. This system is demonstrated to prevent and stop the disaster at railway crossing zones.

The arrangement of the floodgates for rice irrigation canals is currently still using the manual method. This is very burdensome for farmers because it requires time and energy. Therefore, we need a sluice in the irrigation canal that can be done automatically. The purpose of this research is to design a miniature sluice system that can automate the sluice gate in opening and closing the sluice gate based on the water level limit of the channel. The method used in this study is the use of Arduino Uno as data storage, a servo motor that functions as a floodgate controller, a water level sensor to open the floodgate and an ultrasonic sensor that functions to determine the water level. The results of the tool testing in the research of the miniature automatic sluice gate that has been designed, namely the automatic sluice gate will open when the water sensor at the top is exposed to water. The ultrasonic sensor will measure the distance between the sensor and the water surface to make a decision to close the floodgate. If the sensor distance with the water surface is still 14 m, then the floodgate will open 1800, if the sensor distance with the water surface is 4 cm and 14 cm, then the floodgate will open 900 and if the distance between the sensor and the water surface is 4 cm, then the floodgate will be closed.
