This paper focuses on the physical attributes of land that intrinsically limit use and possibly affect values. In particular, we investigate if slope a does decrease its price role in forming more reliable constant-quality indices aggregate house indices. We find that, while slopes do per unit, they have small effect quality-adjusted selected neighborhoods Auckland, New Zealand, where sloped te...
Global warming has been largely driven by increasing atmospheric GHG (Green House Gasses), particularly carbon dioxide caused by fossil fuels burning. The current trend can not be stopped except by reducing fossil fuel consumption or storing organic carbon in soil or earthchr('39')s biological systems such as forests, rangelands and agricultural systems. This study was conducted to determine th...
in this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. the objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. we develop a warp...
Six-year (2005-2010) evolution of water chemistry (Cl(-), NO(3)(-), SO(4)(2-), HCO(3)(-), Na(+), K(+), Ca(2+) and Mg(2+)) and their interactions with morphological properties (i.e., slope and area), land cover, and hydrological seasonality were examined to identify controlling factors and processes governing patterns of stream water quality in the upper Han River, China. Correlation analysis an...
Artificial recharge can be an effective method to raise the groundwater table and to resolve the groundwater crisis in Sefid dasht plain. The most important step to successful accomplishment of artificial recharge is locating suitable areas for artificial recharge. Hence this research carried out with purpose of determining suitable areas for artificial recharge in Sefid dasht plain. Slope, sur...
over-exploitation of groundwater resources in Chaharmahal va Bakhtiari province led to prohibition of some plains in this province. One of these plains is Sefiddasht aquifer. Artificial recharge can be an effective method to raise the groundwater table and resolve the groundwater crisis in this province. The most important step for successful accomplishment of artificial recharge is locating su...
The present study was conducted in Mollaahmad watershed of Ardabil city in 1390 to evaluate the canonical correlation between tillage erosion [slope gradient and position], and grain yield and barley yield components (Sahand cultivar) in order to determine the covariability between the two sets of variables to (1) detect simultaneously occurring patterns in the interdependencies sets of canonic...
ارتباط موقعیت شیب و نوع کاربری در شیب تپههای دارای فرسایش سیلانگل با ضریب فعالیت خاک و حدود آتربرگ
Mudflow erosion is a pervasive problem with adverse consequences for natural ecosystems in most parts of the world. The main factors creating Mudflow erosion are heavy rains, snow and ice melts and flooding rivers. In this study, the effects of slope position and land use type on Mudflow erosion at hill slopes with three different land uses were investigated. For this purpose, three hill slopes...
Groundwater is among the most important resources of drinking water supply ofthe worldwide population. Use of recharge area is one of the methods for artificiallyrecharging groundwater. Selection of suitable sites for artificial recharge is very importantand must be carried out accurately. There are different types of land use, only rangelandsare appropriate for artificial recharge because of t...
Slope stability involves developing a terrain slope profile and determining the geometry of failure surface to compute factor safety. Terrain capture reconstruction traditionally has been expensive, time consuming manpower intensive. This innovative method utilizing unmanned aerial system technology alongside advancement in graphics processing can be proven as more effective cost efficient. res...
