An important and fundamental issue in Iran is to utilize water and to avoid wasting it. Therefore, climate change can be considered as an effective factor on water resources. The most tangible climate change phenomenon is drought which is much important to be identified. In this study, the effect of climate changes on flow rate in Bashar River, Shahmokhtar station of Yasouj city was evaluated u...

Efficient thermal insulation in the harsh desert climate of Saudi Arabia, where cooling requirement buildings is dominant, very important from aspect energy efficiency. Through its eco-friendly properties, one most efficient strategies for reducing use while providing desired comfort. In this study, impact type and thickness on annual consumption was evaluated a sample prototype building locate...

Abstract Green building has aspects which one is referred to the energy efficiency. Energy consumption mainly due mechanical ventilation (MV) therefore it key The utilization of hybrid (HV) by incorporating natural (NV) into system potential save energy. Humid tropics high temperature and humidity causing uncomfortable thermal condition. It poses a challenge utilize systems in this climate effe...

Kenyan farmers’ livelihoods are closely linked to climate conditions. Almost three-quarters of the labor force depend on agriculture for their livelihoods, and almost all farmers depend on timely and adequate rainfall for crop production and husbandry, as only 2 percent of cultivated area is equipped for irrigation. Thus, climate variability and change will have an increasing impact on agricult...

Climate variations and historical land use had a major impact on landscape development in the Brazilian Atlantic Forest (Mata Atlântica). In southeast Brazil, rainforest expanded under warm-humid climate conditions in the late Holocene, but have been dramatically reduced in historical times. Nevertheless, the numerous remaining forest fragments are of outstanding biological richness. In our res...

The greenhouse is vital to protect indoor crops from the harsh hot-humid climate. This study firstly identifies design attributes of greenhouses such as dimension, shapes, orientation, and shading. Secondly, it assesses impacts on daylight performance using VeluxVisualizer. results showed an increase in number skylights caused higher average illuminance greenhouse. All models passed requirement...

Geochemical mass balances were computed for water years 1992-1997 (October 1991 through September 1997) for the five watersheds of the U.S. Geological Survey Water, Energy, and Biogeochemical Budgets (WEBB) Program to determine the primary regional controls on yields of the major dissolved inorganic solutes. The sites, which vary markedly with respect to climate, geology, physiography, and ecol...
