The chernozem has high productivity, most of which is located in Northeast of China. Considering the restrictions of land use and terrain and meteorological conditions, soil erosion and degradation often result in lower agricultural output than expected. Land consolidation is served to consolidate parcels and to enlarge holdings as well as included provisions such as irrigation, drainage infras...

There is considerable controversy over whether pre-Columbian (pre-A.D. 1492) Amazonia was largely "pristine" and sparsely populated by slash-and-burn agriculturists, or instead a densely populated, domesticated landscape, heavily altered by extensive deforestation and anthropogenic burning. The discovery of hundreds of large geometric earthworks beneath intact rainforest across southern Amazoni...

ABSTRACT: Accurate and visual information of working locations is vital for efficient resource planning and location-based scheduling of earthworks, which is missing in existing linear schedules. Thus, construction managers have to depend on subjective decisions for resources allocation and progress monitoring from location aspects. This has caused uncertainties in planning and scheduling, and ...

Recently, there has been an increase in the demand to enhance the intelligence of construction equipment and systems. Especially for semiautonomous and autonomous systems that have great potential for impact on the construction industry, artificial intelligence approaches are required to generate instructions and plans necessary to perform tasks in dynamically changing environments on their own...

Improving safety and productivity of earthwork operations is of paramount importance, especially in congested sites where collisions are more probable. Automated Machine Guidance and Control technology is expected to improve both safety and productivity of earthwork operations by providing excavator operators with higher level of support regarding the path planning of excavators based on site c...

Abstract Inefficiencies in the management of earthmoving equipment greatly contribute to productivity gap infrastructure projects. This paper develops and tests a Deep Neural Network (DNN) model for estimating excavators establishing measure their benchmark. After investigating current practices measuring earthwork during 13 interviews with selected industry experts, DNN was developed tested on...

Land leveling or land grading of surface irrigated fields improve irrigation water distribution and application efficiencies, conserve increases crop productivity. formation for face many constraints (ensuring proper slopes, prevention flood, ensuring canal command over the field, optimizing earthwork, minimizing truck travel distances, equipment utilization). Design engineers traditionally, pe...
