Colloidal Transport in a Coupled Fracture Skin Matrix System with Sinusoidal Fracture Geometry
N. Natarajan, G. Suresh Kumar

Abstract: Colloidal transport in fractured media is a hot topic of research in nuclear engineering as colloids are carriers of radionuclides in the subsurface. A few studies have been conducted on colloidal transport in fractured matrix coupled system in the presence of fracture skin with parallel plate fracture model. An attempt has been made to simulate colloidal transport in sinusoidal fracture skin matrix coupled system numerically. Results suggest that the sinusoidal fracture model behaves differently from the parallel plate model as the fracture aperture is spatially varying. Filtration and remobilization of colloids has negligible effect on the colloidal concentration in the sinusoidal fracture matrix system in the presence of fracture skin.
 

Web-Tourism and Development in Case of Yazd Historical City
Alireza Estelaji, Hadi Sadeghian, Roghaye Ghasemi Darvish Baghal, Seyedeh Leyla Khoda Bakhshi

Abstract: Tourism Web Services is the link between the entrepreneur and the ICT specialist. Apart from web design, graphical solutions and hosting we offer consulting and project management services to ensure the realization of internet related projects within time and budget. We like to build a bridge between those who are the creators of innovative ideas and formulas and those who implement the necessary technology to ensure the translation into actual products and services. Project descriptions, stipulating the expectations and interpretations of the specialists involved are in our view the foundation of any project. A clear project description reduces ambiguity and free interpretations and thus reduces the chances of delay and corrections. The purpose of the research is to study the position of hotel websites in one of the most important counties in Iran, as it pertains to tourism. Yazd City(located in the center of county), known as the driest major city in Iran, and also having recognition as the “sister” of Venice, Italy, has great potential for attracting many tourists in Iran and abroad. Therefore, having a hotel website in a county such as this county can be very important. Hence, this article will compare the situation of hotel websites in Yazd County with standard indexes and use the qualitative-quantitative methodology. The data extracted has come from documents of the Organization of Cultural Heritage and Tourism in Iran, while the qualitative data has been achieved with content analysis from the websites. The result of this research shows that in many cases, the existing situation is not very suitable for the attraction of web users or improving the tourism. The result of this research may help the managers and authorities of tourism to come to a better solution.
 

The Role of Urban Tourism to Achieve Urban Sustainable Development
Alireza Estelaji, Hadi Sadeghian, Zahra Beyhaghi

Abstract: While large cities have always attracted visitors from outside, the concept of cities regarding tourism as an industry of potential importance and encouraging its growth is a recent phenomenon. The demand for travel to cities has greatly increased over the last few decades. While many travel for business or convention purposes, others are traveling on leisure time to learn about other cultures, to develop their specific interests, and to seek entertainment. This paper examines the international phenomenon of urban tourism and its significance as a process affecting urban areas which poses many opportunities and problems for the development, management and functioning of such destinations. Its aim is to raise awareness of the international significance of urban tourism and to develop a more integrated approach towards the study of urban tourism than has hitherto been the case. The effect of the main output, the tourist experience of urban tourism, indirectly forms the focus for other chapters to illustrate how improvements to this outcome can be implemented by modifying some of the principal inputs. This is followed by a discussion of how different forms of tourist motivation lead to discrete and interrelated reasons for visiting urban locations. This article in this very frame has been written with the purpose of urban tourism and its rule in urban sustainable development, by means of descriptive-analytic method and library researches. Finally by dealing with various tourisms, the definition of constant development besides various developments and urban sustainable development, the relation of civic tourism with sustainable development, we’ve gotten to this result that urban tourism has been one of the most substantial actions and plans for urban sustainable developments, and regarding the climatic, historic, cultural, national and relational variation, making plans for this affair is accounted as one the necessities in our country.
 

Fluid Flow Direction Beneath Geothermal Area Based on Self–Potential Data (A Case Study at Mount Patuha, West Java, Indonesia)
Alamta Singarimbun, Mitra Djamal, Fitri Meilawati

Abstract: The purpose of this research is to estimate the fluid flow movement beneath geothermal area by self-potential (SP) data analysis. The value of SP, such as curve shape, contour, and positive-negative value are used to achieve the aims of this research. The study was conducted in the area of Mount Patuha, West Java, Indonesia. This area is estimated as a prospect of geothermal energy. Measurements were conducted by using the amplitude of potential at the position of reference point in the Kawah Putih, with a height of 2213 m above sea level. Electrode moves with the observation point of 10 m distance. The results of this study are shown in the form of estimation of ground water movement to the northeast toward the Kawah Putih area.
 

Public Demand for Shores in Natural Condition: A Contingent Valuation Study in Estonia
M. Reimann, Ü. Ehrlich, H. Tõnisson

Abstract: Approximately 98% of the 3800 km long coastline of Estonia is still in the natural condition. Considering that seashores are attractive as places of residence, natural seashores have a strong pressure from real estate developers. The paper seeks to investigate the willingness of Estonian population to pay for preserving the Estonian seashore in its natural condition. Using the Contingent Valuation Method (CVM) a representative sample of Estonian working-age population was interviewed to find out their willingness to pay. Annual willingness to pay is asked separately for all main natural seashore types in Estonia, which include silty shore, till shore, cliffed shore, gravel shore, sandy shore. A total demand function was worked out to find the total demand for seashore in its natural condition as a valuable environmental good and on the basis of that a total demand curve was constructed. By integrating the demand curve we received results that annual total demand of the working-age population for seashores in their natural condition is 42.5 million euros. Important sociometric indicators for willingness to pay proved to be age and income. The study shows that the Estonian seashores in the natural condition are valuable environmental goods for which there is substantial demand.
