Dissolved Oxygen Prediction Using Support Vector Machine Sorayya Malek, Mogeeb Mosleh, Sharifah M
World Academy of Science, Engineering and Technology International Journal of Bioengineering and Life Sciences Vol:8, No:1, 2014 Dissolved Oxygen Prediction Using Support Vector Machine Sorayya Malek, Mogeeb Mosleh, Sharifah M. Syed [10]-[12]. ANN is a well-suited method with self-adaptability, Abstract—In this study, Support Vector Machine (SVM) self-organization, and error tolerance for nonlinear simulation. technique was applied to predict the dichotomized value of Dissolved However, this method has limitationsdue to its complex oxygen (DO) from two freshwater lakes namely Chini and Bera Lake structure that requires a great amount of training data, (Malaysia). Data sample contained 11 parameters for water quality difficulty in tuning the structure parameter that is mainly features from year 2005 until 2009. All data parameters were used to predicate the dissolved oxygen concentration which was based on experience, not sensitive to the noise produce and its dichotomized into 3 different levels (High, Medium, and Low). The “black box” nature that makes it difficult to understand and input parameters were ranked, and forward selection method was interpret the data [13], [14]. applied to determine the optimum parameters that yield the lowest Considering the drawbacks of ANN, recently support vector errors, and highest accuracy. Initial results showed that pH, Water machine (SVM) are become widely used for predicting the Temperature, and Conductivity are the most important parameters DO concentration [15], [16]. It is a new machine-learning that significantly affect the predication of DO. Then, SVM model was applied using the Anova kernel with those parameters yielded technology based on statistical theory and derived from 74% accuracy rate. -

Listening to Women Fishers on the Sekong River: Fostering Resilience in Village Fishery Co-Management
Listening to Women Fishers on the Sekong River: Fostering Resilience in Village Fishery Co-Management Charlotte Moser Abstract The accelerated economic development of landlocked Laos, combined with extreme climate variables, points to dramatic transformations in subsistence fisheries on its rivers. In the country’s first Fisheries Law, adopted in 2009, co-management of village fisheries is required as a way to promote sustainable development at a local level. The co-management model, however, does not stipulate participation by women fishers, important stakeholders who make up almost one-half of all Lao fishers and whose work contributes directly to family nutrition and well-being. Based on fieldwork conducted in fishing villages on the Sekong River in southern Laos in 2013, this paper takes an ecosystems approach to discuss how the country can build resilience and social cohesion into fisheries by incorporating women and their knowledge into village fishery management. In the process, the health of river ecosystems and food security will improve, while women fishers will acquire new skills to help them avoid ‘poverty traps.’ Introduction The concept of resilience is central to effective adaptive management of ecosystems. Developed by ecologist C.S. “Buzz” Holling in the 1970s as a theory for managing complex ecosystems, resilience theory suggests that an ecosystem is resilient if it has the ability to remain cohesive during periods of extreme perturbations or what are called ‘shocks’ (Holling 1973). Rather than “bouncing back” to a former equilibrium, an ecosystem is resilient if it can absorb changes in internal and external variables and still persist, albeit in a somewhat different yet robust form. -

Nordiana School of Physics, Universiti Sains Malaysia, Penang, Malaysia ABSTRACT Natural process of seawater intrusion occurs in many coastal areas all around the world. Previous experiences have recorded that the phenomena will cause a problem to the freshwater aquifer due to its salinity contamination. Conventional approach on saltwater detection also suffers from efficiency in term of cost, time and data coverage. Hence, this study has introduced an electrical resistivity imaging (ERI) for saltwater intrusion mapping based on time lapse condition. Data acquisition and processing of ERI was performed using ABEM SAS 4000 and RES2DINV software. -

Assessing the Hydrodynamic Pattern in Different Lakes of Malaysia 73
DOI: 10.5772/intechopen.73274 ProvisionalChapter chapter 5 Assessing thethe HydrodynamicHydrodynamic PatternPattern inin DifferentDifferent Lakes Lakes of Malaysia Zati Sharip, Shahirwan Aman Shah, Aminuddin Jamin and Juhaimi JusohJusoh Additional information isis available atat thethe endend ofof thethe chapterchapter http://dx.doi.org/10.5772/intechopen.73274 Abstract Hydrodynamic simulations using three-dimensional numerical model were carried out in three different shallow tropical lakes to understand the characteristics of water movement in the respective water bodies. The models were based on meteorological data from the nearest stations and calibrated with current measurement, temperature, or water-level data. The results show good agreement between measured and simulated velocities and/ or temperature at certain depth. This study found that the major driving forces of the hydrodynamic pattern were different in the three lakes. Hydrodynamic simulations showed that Bukit Merah and Durian Tunggal reservoirs were more sensitive to wind- driven motion. Floodplain lakes, such as Bera Lake, are more sensitive to flood inflow by the main river during the monsoon season. Convective motion driven by water tempera- ture gradient was important for Bukit Merah and Bera Lake. Keywords: circulation, convective motion, hydrodynamic simulation, numerical modeling, wind-driven motion 1. Introduction Hydrodynamic studies in water bodies are important areas of study for researchers and managers to understand patterns of surface water movement and pollutant transport. Varia- tions in hydrodynamics among lakes have been associated with differences in morphological geometries and the surrounding topographies as well as hydrometeorological and geochemi- cal influences [1]. Simulations of hydrodynamic pattern using high-dimensional numerical models have become useful for understanding the complex role of different forcing mecha- nisms. -

Accepted 26 April, 2013 Hydrological evaluation and sediment loading of the Chini Lake catchment was investigated. Sediment loads and water discharge from seven selected feeder rivers were measured over a period of one year (January to December 2006). Suspended sediment concentration was measured by the standard method. The annual rainfall from 1984 to 2006 at the Chini Lake catchment ranged from 1487.70 mm (1997) to 3071.40 mm (1994), with the annual rainfall for 2006 being 2544.50 mm. Stream flow rate during the sampling periods was relatively slow, ranging from 0.001 to 1.31 m3s-1 (or an average of 0.21 m3s-1). The highest and lowest stream flow discharges were recorded from the Gumum River and Cenahan River subcatchment. The amount of sediment load ranged from 0.49 to 166.02 kg/km2/day (or an average of 30.57 kg/km2/day) in the study area.
