Improving capacity and design of water supply system for the case of Mazar-e-Sharif City
In the world, improving quality and reliability of water supply systems, improving access to clean drinking water for the populations in conditions of development and intensive growth of urban settlements are considered an important issue. In this research the most important issue is improving the calculation methods of water delivery and distribution systems within urban water supply complexes. In most countries such as the USA, Germany, Russia, Israel, South Korea, China and other economically developed countries, special attention has been paid to provide clean drinking water for their population, improve the quality of design for water supply systems and ensure reliability and design of water distribution system for urban settlements.
A water supply network for distributing the water for drinking and other purposes is a component of a city and municipal planning. Therefore, it needs to be planned and designed by city planners and civil engineers with the utmost care. It is also necessary to consider of factors that will have an impact, such as the location of the town or city, its current water demand, the growth in the demand in future, leakage in the systems, the required pressure in the pipes, losses in the pipes, etc. Targeted research aimed to develop scientifically grounded calculation methods for studying and developing theoretical bases for calculation water delivery and distribution system within urban water supply complexes. The study also considered new working conditions and requirements for their modernization, which are especially important worldwide. In this study the most important tasks are to improve calculation methods of water delivery and distribution systems under the condition of multi-mode water flow in pipes and uncertainties of network parameters.
Further, Mazar-e-Sharif city has been considered as a case to apply the developed mathematical calculation, describing water delivery and distribution processes, rational development and reconstruction of water delivery and distribution systems.
Currently, a wide range of comprehensive studies is being carried out in many countries on the use of modern computer technologies on the implementation of comprehensive measures to improve access to clean drinking water in city, through the construction of new water tanks, an extension of the existing water tanks, sewerage facilities and water supply network.
The development strategy of the Islamic Republic of Afghanistan in line with SDG’s is first improving the supply and delivery of clean drinking water in each province of the country. Since many years the local Government of Balkh province and people of Mazar-e-sharif city are wishing to have the new modern water supply system to satisfy all needs but unfortunately, they did not success to get this opportunity. Mazar-e-Sharif is the second largest city in Afghanistan and the population is growing day by day as due to economic reasons people from other provinces immigrate to Mazar. The current water supply system is the individual/local distribution system made by the local community and some NGOs which are not standard, and the quality of the water is not satisfactory.:Table of Content

Effect of Knowledge and Motivation Toward Seaweed Farmers’ Cultivation Behavior
Abstract: This study was carried out to solve the problem of the ice-ice disease faced by seaweed farmers. The
purpose of this research was to describe the effect of ice-ice disease knowledge and seaweed farming
knowledge to cutivation behavior; the effect of ice-ice disease knowledge, and the seaweed cultivation
knowledge to the cultivation motivation; and the effect of cultivating motivation to the cutivation behavior
of the seaweed farmers. This research is a correlational study to look at the relationships between
exogenous with endogenous variables. The study involved 60 seaweed farmers in Tablolong village. The
data of this study consists of cultivation behavior and motivation collected by questionnaire, the data about
knowledge of ice-ice disease, and seaweed cultivation gathered through the knowledge test sheet. Data
were analyzed by path analysis through SPSS for Window.The results showed that there is a direct effect of
the ice-ice disease knowledge toward the cultivation motivation but not for cultivation knowledge; and
there is a direct effect of the cultivation motivation to the cultivation behavior. It can be concluded that the
ice-ice knowledge directly effect toward cultivation motivation and the cultivation motivation effect toward
behavior of the seaweed farmers in Kupang district
