BACKGROUND Effective provider-parent communication can improve childhood vaccination uptake and strengthen immunisation services in low- and middle-income countries (LMICs). Building capacity to improve communication strategies has been neglected. Rigorous research exists but is not readily found or applicable to LMICs, making it difficult for policy makers to use it to inform vaccination polic...
Lack of precipitation and it`s result water deficit is one of the most important problems in arid and semi-arid regions. Developing of (RWH) can be used as a method of increasing cultivation, play a significant role. (RWH) methods obviate water requirement and due to its properties can decrease flood risk and control sediments. In this article during a statistical analysis, determine effect of ...
Analysis of vegetation-based management scenarios using MCDM in the Ramian watershed, Golestan, Iran
This research has concentrated on the physical and socio-economic impacts of vegetation-based management scenarios targeting on flooding and soil erosion issues in the Ramian watersheds. The Ramian watershed with an approximate area of 24000 ha is located in Golestan, Iran. For each sub-watershed, four biological actions (activities) and 16 management scenarios have been considered. Physical im...
The morphological changes in the river channel over periods that occur due to flood events, affected sinuosity index of channel. characteristic like also determines intensity a Recent losses have increased as result variability rainfall; simultaneously such problems are coming up with sustainable development. attempted research study has been carried out evaluate and understand bank stability M...
Earth dams have been used widely recently in flood and sedimentation control projects and feeding ground waters in country's watersheds and correct locating for such structures is necessary for increasing their efficiency. In this work, it is attempted to determine the correct locations for constricting earth dams in Yoosef-abad watershed in Tabas using v and incorporating information layers. T...
Abstract Morphometric analysis is a powerful tool to understand the hydrological process quantitatively and main requirement determine characteristics of watershed. drainage Sedayu River Sub-watershed, Semaka District, Tanggamus Regency, Lampung Province was carried out using Digital Elevation Model (DEM) data. The primary data used aerial photography drones, location photos representing waters...
the modeling can provide a quantitative approach and consistency in the estimationsoil erosion and sediment yield by a wide range of conditions. in this study, the integration method of revised universal soil loss equation model, geographic information system and remote sensing techniques were used in order to identify the spatial distribution of soil erosion and sediment yield in the talar wat...
Hydrological models are used to represent the rainfallrunoff and pollutant transport mechanisms within watersheds. Accurate representation of these dynamic and complex natural processes within a watershed is an important step in managing and protecting a watershed Artificial neural network (ANN) models are often used in hydrologic modeling. Typical ANN models are trained to use lumped data. How...
