Повний текст джерелаBulk water supply systems are usually designed according to deterministic design guidelines. In South Africa, design guidelines specify that a bulk storage reservoir should have a storage capacity of 48 hours of annual average daily demand (AADD), and the feeder pipe a capacity of 1.5 times AADD (CSIR, 2000). Nel & Haarhoff (1996) proposed a stochastic analysis method that allowed the reliability of a reservoir to be estimated based on a Monte Carlo analysis of consumer demand, fire water demand and pipe failures. Van Zyl et al. (2008) developed this method further and proposed a design criterion of one failure in ten years under seasonal peak conditions. In this study, a method for the optimal design of bulk water supply systems is proposed with the design variables being the configuration of the feeder pipe system, the feeder pipe diameters (i.e. capacity), and the size of the bulk storage reservoir. The stochastic analysis method is applied to determine a trade-off curve between system cost and reliability, from which the designer can select a suitable solution. Optimisation of the bulk system was performed using the multi-objective genetic algorithm, NSGA-II. As Monte Carlo sampling can be computationally expensive, especially when large numbers of simulations are required in an optimisation exercise, a compression heuristic was implemented and refined to reduce the computational effort required of the stochastic simulation. Use of the compression heuristic instead of full Monte Carlo simulation in the reliability analysis achieved computational time savings of around 75% for the optimisation of a typical system. Application of the optimisation model showed that it was able to successfully produce a set of Pareto-optimal solutions ranging from low reliability, low cost solutions to high reliability, high cost solutions. The proposed method was first applied to a typical system, resulting in an optimal reservoir size of approximately 22 h AADD and feeder pipe capacity of 2 times AADD. This solution achieved 9% savings in total system cost compared to the South African design guidelines. In addition, the optimal solution proved to have better reliability that one designed according to South African guidelines. A sensitivity analysis demonstrated the effects of changing various system and stochastic parameters from typical to low and high values. The sensitivity results revealed that the length of the feeder pipe system has the greatest impact on both the cost and reliability of the bulk system. It was also found that a single feeder pipe is optimal in most cases, and that parallel feeder pipes are only optimal for short feeder pipe lengths. The optimisation model is capable of narrowing down the search region to a handful of possible design solutions, and can thus be used by the engineer as a tool to assist with the design of the final system.

Abstract In recent years, changes of the global environment and climate have resulted in sudden increase of water turbidity and hence no water supply whenever there is a storm. During the dry season or a drought, on the other hand, there is shortage in water resources. These have emerge a challenge for water supply at water sources. Therefore, this research considers district water supply systems(including the water supply station) in the future to allocate multiple water sources and quickly supply water to different districts or supply water with less quantity and optimal pressure to maintain the basic domestic water consumption of the public. This research applies the concept of system life cycle in developing a stable, diversified and informative water supply system to achieve least water supply risk, highest stability, and lowest cost. The comprehensive problems of water supply and tries to come up with solutions. Methods adopted include (1) Developing and building district water supply systems to mainly accommodate multiple water sources allocation. Two parallel pipes and connecting piping are established on major water supply pipes of the allocation system and two wells are set up in each district piping network to connect with major water supply pipes of different piping. Other parts and tubing or piping outside each district are completely separated. The improved district piping networks can supply water independently and instantly carry out water supply allocation as well as assure efficacy of reasonable supply water pressure. (2) Doing the hydraulic power simulation analysis and establishing an optimal model, taking into consideration the initial piping setup charge, road repair charge and management and operation charge to achieve minimum cost and maximum water supply. Meanwhile, inspired Genetic Algorithm is applied to find the solution and find a more cost-effective design proposal in compliance with design regulations and principles. (3) Mapping out the support system of the multiple water supply station in the district, which in ordinary times supplies users with multi-alternative drinking water (such as magnetized water, and oxygenated water) or meet the basic demand for drinking water of the public in case of emergencies where the station cannot supply water to ensure maximized reliability in water supply. This research analyzes the optimal setup location of the water supply station by Fuzzy C-Means Algorithm for each supply station can make the best use of. (4) We want to look for monitoring stations ,That number and sites of of stations can be obtained by Policy-making model of simulating site selecting of the district urban water network. Then setting monitor systems in districts to exactly control water input and output and the optimal water pressure, minimize water leaks, check on water leaks or water pollution in the districts, and make sure that water pressure and quantity are stable. If the piping network is abnormal or is broken, the leaking spots can be located very quickly and repairs can be made to restore normal water supply in a rapid manner. Analyses show that this method saves water loss as a result of broken pipes by 67% and cuts down leak volume by more than 23.5% when water pressure is controlled at a reasonable level. Through case study and analysis, this research finds that the shortage risk of major water supply pipes and the district piping network itself in a district piping network system management model drop to 0.018 from 0.202 when a monitor system is added; that is, improvement in the district piping network system can result in 1.23 times of increase in water supply reliability. Therefore, if the water within water supply districts is decreased or cannot be supplied completely due to natural disasters or other situations, the improved small district piping network system established in this research (including the water supply station system) could be used to provide the public with basic domestic water and maximize the water supply efficacy in the district.

This study proposes a framework to evaluate the water supply system reliability through life cycle assessment and system reliability theorems. Water supply systems in Taiwan mainly consist of three major subsystems: (1) raw water from reservoirs, (2) treatment plants, and (3) distribution networks. Reservoirs provide raw water, and water treatment plants convert raw water into drinking water that is later distributed to consumers through distribution networks. Reliability of water supply systems is composed of water quantity and quality. Mechanical failures occurring in the water treatment and distribution sections potentially lead to water supply system failures in terms of water quantity and quality; therefore, this study takes into account the mechanical failures that affect water supply system reliability. Life cycle assessment and system reliability theorems are employed to evaluate the water supply system. Shihmen Reservoir water supply system is hypothetically taken as a case study.

Abstract The study aims at building up a set of research methodology to estimate the reliability of regional water supply system when ENSO occurs. This research methodology is also applied on Tan-Shui river basin so as to highlight practicability of this methodology. The study firstly introduces the definition and occurrence of ENSO. Furthermore, the cause of building research methodology is illustrated: (1) 30 sets of Nino3.4 Index of defining ENSO are generated by Thomas and Fiering seasonal model. (2) Two regression equations, one is between Nino3.4 Index and temperature, the other is between Nino3.4 Index and precipitation, are separately established. (3) Runoff is simulated by inputting temperature and precipitation into the water balance model. (4) Water supply of each demand note is gained by optimization model. (5) Shortage index (MSI) is evaluated by water supply and demand. And (6) the reliability of water supply system is estimated by MSI The study applies the methodology on Hsintien Stream Region and Tahan Stream Region to estimate the reliability of satisfying each target demand in the research area under current (Year 1996) water demand and water resource facilities. Before applying the methodology, both model validation and parameter calibration are done in order to obtain the parameters of each model. The methodology of study is applied to obtain following conclusions: (1) the trend of correlation between Nino3.4 Index and temperature is similar with it between Nino3.4 Index and precipitation. They are both weak correlated in the same month. However, they are stronger correlated in one month lag and the strongest in two months lag. (2) The study discovers that ENSO affects rainfall in northern and middle Taiwan more obvious than in other sections, but litter different in temperature between regions. (3) The water shortage condition is more serious in Tahan Stream Region than Hsintien Stream Region under current (Year 1996) water demand and water resource facilities. (4) In Tahan stream region, The reliability of MSI, which is 0.1, is 50.35%; which is 0.5 is 78.35%; and which is 1 is 95.58% under current (Year 1996) water demand and water resource facilities. (5) Hsintien Stream Region is not shortage in water demand. (6) In whole region, the reliability of MSI, which is 0.1, is 66.35%; which is 0.2 is 82.47%; and which is greater than 0.3 is 93.44% under current (Year 1996) water demand and water resource facilities.

Повний текст джерелаThis thesis considers water supply and divides the water supply environment into three categories; the macro water supply environment, the water supply scheme and the consumers. Each of the categories is briefly explored in terms of the factors that may influence it. Subsequently, some of the unique features of a bulk water distribution system are dealt with, as well as different approaches related to bulk water distribution system design and assessment. One of these approaches, the probabilistic approach, offers unique features to assess the reliability of a bulk water distribution system but requires that the probabilistic characteristics of the stochastic events be quantified. The above prompted the goal of this thesis; “…to assess and quantify the probabilistic characteristics of selected factors that may compromise bulk water distribution reliability”. The objectives set and dealt with in this thesis are: • Conducting a literature review that explores uncertainty, reliability, models and techniques, highlighting selected factors that may compromise bulk water distribution reliability, as well as bulk water distribution system water requirements. • Quantifying the probabilistic characteristics of water distribution pipeline failures. • Quantifying the probabilistic characteristics of pipeline failures caused by sinkholes in dolomitic areas. • Quantifying the probabilistic characteristics of power supply failures. This study provides a comprehensive summary of a range of uncertainties that may compromise bulk water distribution reliability. However, the greatest value added corresponds to the following: • It establishes a benchmark related to the probabilistic characteristics of pipeline failures for five pipeline material categories, related to pipeline failure rates and pipeline repair times. • A new methodology is developed in terms of which the probabilistic characteristics of pipeline failures caused by sinkholes in dolomitic areas can be quantified. • It provides a benchmark of the probabilistic characteristics of power supply failures at bulk water distribution pump stations. Proposals are made related to future research needs, divided into two categories: • Complementary research needs that will complement and enhance the work undertaken within this thesis. • Promotional research needs that will promote the practical application of the outcomes generated as part of this thesis.

Raw water sources in Taiwan mainly come from reservoirs. Water treatment plants are commissioned to purify raw water to become drinking water. Through water distribution network, purified water can be delivered to the water consumers. Recently, the high turbidity of raw water induced by intensive rainfalls overloads the water treatment plants and causes water supply temporarily disrupted in the Shihmen Reservoir water supply area. Previous studies generally focus on the quantity of water rather than its quality. As consequence, it leads to underestimate the risk of water shortage and overestimate the resiliency, and vulnerability. This study presents a water supply system reliability analysis methodology and develops its evaluation model that takes into account both quality and quantity of water. Historical flow records and data generated by the time series model are both used in the water supply system reliability evaluation model. Results show that the indices such as water shortage index, resiliency and vulnerability increase if raw water turbidity is considered. Conversely, the reliability of water supply system reduces. Though the effect of higher turbidity is not found significant on system reliability in long term, short term events such as typhoons that can cause high turbidity still cannot be ignored.

Water is connected with everybody’s daily life. The quality of the drinking water is essential to all the people. Its key factors conclude water quality, water pressure and water quantity. The water- pipe distribution network, though broken at times, is usually not repaired in time, so it stained water quality and caused loss of the water quantity, which leads to the reduction of water pressure or cannot supply drinking water at all. Therefore, consumers tend to misunderstand and feel discontent for water supply system. The research has two purposes. One is to analyze the leakage rate of every district, and the other is to calculate the reliability of every district for water supply system. Subject to the optimal economic principle of the water- pipe distribution network, water supply system can fully satisfy consumer’s demand. I hope that the research can offer managerial reference for every water supply system in shortening expenditure. First, the means and contents of the research are to collect all details of the table for water supply network district, water pressure, water quantity and broken pipe leakage. They are all related to the water pipe number, which can provide the inquired details according to different conditions in Access. At the same time, I make use of SPSS or EXCEL to analyze the above mentioned details. The main conclusions of the research are the following: The leakage ratios and leakage quantity of Hou-tung, Chin-kua-shih… five districts etc I suggest that they must be inspected seriously. The reliability of every district for water supply system and the age of the pipe that the ratio of broken pipe over 1 and the age of the pipe over 30 years have 7 pieces. The above will lower the reliability of the water supply system, so I suggest that they must be replaced with priority.

This study aims to develop a model for assessing the reliability of resulting irrigation-water supply from a water allocation model by means of uncertainty and risk analysis under consideration of variations in the water demand for irrigation, inflow from river, outflow into hydraulic structures, and opening height of canal gates. The aforementioned reliability is regarded as the probability of supply water exceeding a specific magnitude. In detail, the proposed reliability assessment model consists of two equations, i.e. the relationship between irrigation-water supply and uncertainty factors and calculation of probability of exceeding a water demand (i.e. reliablity), the effect of aforementioned uncertainty factors on the irrigation water at a number of branches within irrigation region of interest should be accordingly quantified and evaluated. Zhudong canal located within the Touqian river watershed in northern Taiwan are selected as the study area. Regarding the Zhdong Canal, runoff from Shanping Weir is major inflow, and 15 branches in association with the water gates, two reservoirs (i.e. Baoshan and Baoshan II) as well as a water purification plant (i.e. Yuandon) are taken into account in the establishment of water allocation model, RIBASIM model. Additionally, two types of uncertainty factors, hydrological factors (i.e. Inflow from Shanping Weir, outflow into reservoir and water treatment plants) and irrigation features (maximum diverted flow for gate and irrigation-water demand regarding branches) are adopted in the proposed model. After that, 1000 simulations of uncertainty factors are obtained through the Multi-variates Monte Carol method and they are then imported into the RIBASIM to estimate the decade-based (10-day) water supply for entire branches in the Zhudong canal. By doing so, the exceedance probability (i.e. reliability) of simulated irrigation-water supply for entire branches can be computed by using the advanced first order and second moment (AFOSM) approach integrated with the relationship of irrigation-water supply with the uncertainty factors derived by the multi-variate regression analysis. Eventually, the equation of calculating exceedance probability of irrigation-water supply can be obtained through the logistic regression analysis. In this study, sensitivity analysis for irrigation-water supply is carried out by using the normal regression equation with 1000 simulations of irrigation-water supply at all branches. This reveals that the estimated irrigation-water supply is significantly sensitive to the inflow from Shanping Weir, outflow into Banshan reservoir and Yuandon plant, and the maximum diverted flow. According to the results from the risk analysis, the variations in the above four uncertainty factors markedly impact the reliability of irrigation-water supply for all branches in the Zhudong canal. This can be known that more inflow from Shanping weir can effectively enhance the reliability of irrigation-water supply at entire branches. However, the variation in outflow into the Baoshan reservoir impacts the reliability of irrigation-water supply, especially for the upstream braches from the Baoshan reservoir, i.e. the 8th – 14th branch, of which the reliability of irrigation-water supply declines with more outflow form the Zhudong canal into the Baoshan reservoir. Nonetheless, dissimilar to the Baoshan reservoir, the irrigation-water supply at the 1st-3rd branch is obviously proportional to the outflow into the Yuandon water-treatment plant. This implies that at the 1st-3rd branch, the irrigation water can be supplied with high reliability as a result of outflow into Yuandon water-treatment plant exceeding its demand of interest. Moreover, in accordance with the coefficient of variation (CV) for the irrigation-water supply, 15 irrigation branches within Zhudong canal can be classified into three groups nearby: the 1st -2nd branch (group 1), the 3rd-7th branch (group 2) and the 8th-14th branch (group 3) separated at the the Yuandon water-treatment plant and Baoshan Reservoir, respectively. In summary, the proposed reliability-assessment model for irrigation-water supply at branches in the Zhudong canal can reasonably describe the change in the reliability of irrigation-water supply at entire branches in the Zhudong canal attributed to uncertainties in hydrological factors and irrigation features. Therefore, it is expected that results from the proposed reliability-assessment model can be taken reference to the regulation of strategy for drought mitigation. In addition, the change in uncertainty factors, including the inflow from the Shanping weir, outflow into Yuandon treatment plant and the maximum diverted flow for each branch obviously and positively influence the exceedance probability distribution of irrigation-water supply. Above three uncertainty factors can increase the reliability of irrigation-water supply by increasing their amount, excluding outflow into Baoshan Reservoir which is inversely related to the exceedance probability of irrigation-water supply (i.e. reliability).

This study aims to develop a reliability assessment model for water supply from the reservoir (RA_WS_Res) in order to quantify the risk of water supply due to the uncertainty factors. The uncertainty factors group into three types: hydrological factors, reservoir operation rules, and parameters of rainfall-runoff model (i.e. Sacramento Soil Moisture Accounting, SAC-SMA). Specifically, the hydrological factors includes the rainfall characteristics, baseflow, evaporation, and initial water level of dam; the reservoir operation rules involve the flood level, target level and firm storage level. In detail, the proposed RA_WS_Res model primarily employs the multivariate Monte Carlo simulation (Wu et al., 2006) to generate the uncertainty factors in order to produce dam inflow by incorporating with the SAC-SMA model. After that, the water supply at the demand nodes of interest can be obtained from the water-resource allocation model (River Basin Simulation model, Ribasim). Using the simulated uncertainty factors and corresponding estimated water supply, the resulting exceedance probability (i.e. insufficient risk) can be calculated by using the uncertainty and risk analysis (i.e. advanced first-order and second moment, AFOSM). Eventually, this study carries out the logistic regression analysis to establish the relationship between the exceedance probability and average rainfall intensity for various 10-day periods at the specific nodes. This relationship is named the exceedance probability calculation equation. In summary, the proposed RA_WS_Res model is composed of five components: simulation of uncertainty factors, estimation of dam inflow, estimation of water supply, quantification of insufficient risk, and establishment of the exceedance calculation equation. It is expected that the proposed RA_WS_Res model can quantify the effect of variation in uncertainty factors, especially due to climate change, on the reliability of water supply from the reservoir. Shihmen Reservoir watershed is selected as the study area and six demand locations within the watershed are selects as the study nodes. In addition, the hourly rainfall data from 1987 to 2014 and associated hydrological data (i.e. evaporation and baseflow) as well as the operation rules are used in the model development and application. The results indicate that, amond these uncertainty factors, the reliability of water supply is more sensitive to uncertainties in the initial water level, average rainfall intensity in each 10-day period, baseflow and the range between the target level and firm storage level. In detail, the effect of variation in the initial water level to water supply gradually reduces with time (ten days) from the 1st ten-day to the 15th ten-day period in Shihmen Reservoir. Moreover, the average rainfall intensity and baseflow are positively related to water supply; this implies that the baseflow plays an important role in the estimation of water supply, besides the average rainfall intensity. In particular, the range between the target and firm storage levels has significantly influence on the reliability of water supply. This reveals that regulating the operation rules for the reservoir not only focuses on the flood mitigation and prevention, but also takes into account the water-supply reliability. Consequently, the proposed RA_WS_Res model can effectively and reasonably quantify the insufficient risk (i.e. exceedance probability) of water supply attributed to variation in uncertainty factors due to climate change; this can be useful for the water-resource allocation and analysis.
