Optimizing land leveling by applying warped surface
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...
متن کاملLand Use Regulation and Productivity – Land Matters Land Use Regulation and Productivity – Land Matters: Evidence from a Uk Supermarket Chain
We use unique store-specific data for a major UK supermarket chain to estimate the impact of planning, which restricts both the size and location of stores, on store output. Using the quasi-natural experiment of the variation in planning policies between England and other UK countries and a difference-in-difference approach, we isolate the impact of Town Centre First (TCF) policies. We find tha...
متن کاملLand use impacts on surface water quality by statistical approaches
Surface waters are the most important economic resource for humans which provide water for agricultural, industrial and anthropogenic activities. Surface water quality plays vital role in protecting aquatic ecosystems. Unplanned urbanization, intense agricultural activities and deforestation are positively associated with carbon, nitrogen and phosphorous related water quality parameters. Multip...
متن کاملAssessment of Terrain and Land Use/Land Cover Changes of Mine Sites using Geospatial Techniques in Plateau State, Nigeria
In this paper, we report a geospatial assessment of the selected mine sites in the Plateau State, Nigeria. The aim of this work is to determine the impact of mining on the terrain as well as the Land Use/Land Cover (LULC) of the host communities. The Shuttle Radar Topographic Mission (SRTM) is used for the terrain mapping. The derived impact of mining on LULC between 1975 and 2014 is determined...
متن کاملPerformance comparison of land change modeling techniques for land use projection of arid watersheds
The change of land use/land cover has been known as an imperative force in environmental alteration, especially in arid and semi-arid areas. This research was mainly aimed to assess the validity of two major types of land change modeling techniques via a three dimensional approach in Birjand urban watershed located in an arid climatic region of Iran. Thus, a Markovian approach based on two suit...
