Category Archives: Water Resource Engineering

Water resources engineering is the profession that is responsible for the planning, development and management of water resources. From estimating the amount of water available to designing the physical and non-physical infrastructure needed to meet the water needs of society and the environment, civil engineers play a central role within a multi-disciplinary team. To ensure access to clean safe drinking water, civil engineers design, build and manage the water intakes, the water treatment plants and the network of pipes that convey water to your tap. Civil engineers use state-of-the-art technologies to treat domestic and industrial wastewaters before discharging treated water back into the environment.

The Bowen Ratio Method and PAN Evaporation Explained

Energy Balance and The Bowen Ratio Method Explained During the Evapotranspiration process, energy is used to convert water from liquid to vapor and transfer the vapor to the atmosphere. The Bowen-ratio method, which were used to estimate ET, are based on characteristics of the energy budget associated with atmospheric fluxes. Instrumentation two solid-state temperature and… Read More »
