Well Injectivity Management during Geological Carbon Sequestration Activity
Abstract: It is well known that the saline aquifer formations are considered very reliable candidates for carbon sequestration because of their wide availability and they have good storage capacity. Due to high formation salinity, there a big concern about bore formation dry-out resulting from the salt precipitation in the form of halite (NaCl). The mutual solubility between CO2 and brine is responsible for creating the salt deposits, this processes may take …

Parameter Identification at Large Scale through Solution of the Inverse Problem
Abstract: The fundamental benefit of groundwater modeling is to predict the response of the aquifer to the proposed man-mad excitation (e.g., pumping artificial recharge). Inverse analysis is frequently used for large-scale real-world problems, where the number of unknown parameters that will fully represent the heterogeneity becomes very large and the inverse analysis solution becomes ill-posed, to overcome this problem, in the present paper the study domain is divided into zones connected …

Automatic Irrigation System on Sensing Soil Moisture Content
Abstract: AbstractIn developing countries like Bangladesh, farmers depend on rivers and rainfall to water their crops properly. Even though water pumps are used for irrigation purposes, the farmers have to operate those manually. In this paper, a system is proposed to reduce the human intervention as it will switch the motor on/off automatically after sensing the soil moisture content. Further system will allow the farmers to receive much needed rest and …
