at the beginning of twenty-first century, the water crisis in the priority policy andmanagement is inside and outside of the country as principle thoroughly human, social,economic and political rulers of the country is considered abundant. the world bank hasannounced that during 1960 and 2025, water resources in middle east, from 3430 m3 for theeach person in year reach to 667 m3 because of pop...

This is a preliminary attempt towards a wider use of Artificial Neural Networks in the management of mountainous water supplies. It proposes a model to be used effectively in the estimation of the average annual water supply, in each mountainous watershed of Cyprus. This is really a crucial task, especially during the long dry summer months of the island. On the other hand the evaluation of the...

This study aims to provide a description of how elementary school students in grade 2 recognize the types insects through their existence nature around us. The method used this research is semi-experimental research, characteristics experimental include manipulation and observation. Samples were taken from two populations, namely: mountainous areas coastal areas. question whether there are diff...

Background & Aim: Gundelia tournefortii L. (Tumbleweed) has been identified as one of the well-known and widely distributed plants with various applications in some of Asian and North African countries. It belongs to the (Asteraceae) family and grows in the Middle East particularly in the temperate, mountainous and semi desert areas of countries such as Iran, Iraq, Tur...

Mountainous areas in China account for two-thirds of the total land area. Due to rapid urbanization, rural population emigration in China's mountainous areas is very significant. This raises the question to which degree such population emigration influences the vegetation greenness in these areas. In this study, 9,753 sample areas (each sample measured about 64 square kilometers) were randomly ...

Common cyclamen (Cyclamen purpurascens Mill.) is the only representative of its genus in Slovenia where it a widespread species, growing from sea level to high mountainous areas. It thrives all four major phytogeographic regions: Alpine, Dinaric, sub-Pannonian and sub-Mediterranean, both transitional regions, pre-Alpine pre-Dinaric, reacts quickly weather conditions. found mostly deciduous mixe...

Land cover mapping in mountainous areas is a notoriously challenging task due to the rugged terrain and high spatial heterogeneity of land surfaces as well as the frequent cloud contamination of satellite imagery. Taking Southwestern China (a typical mountainous region) as an example, this paper established a new HC-MMK approach (Hierarchical Classification based on Multi-source and Multi-tempo...
