Groundwater Level Measurement to Generate Water Table Map for Aquifer Characterization and Management
The Water Section creates a wide variety of spatial products from GIS datasets, and decision-support tools, data visualizations, and traditional static maps. Groundwater is generally portable at source, available in-situ and has low temporal variability which makes it the most important source of water for rural communities. However, groundwater occurrence in any region of the world is largely dependent on the nature and type of aquifer. This is because the nature and type of aquifer determines the quantity of groundwater that can be abstracted in a particular area to support her population. This is why it is extremely important to determine the groundwater potential of an area for sustainable development and management.

Pumping Test Evaluation for Well Efficiency and Aquifer Characterisation
Step Drawdown Test (STD) is commonly used to differentiate the laminar and turbulent components of total drawdown and to determine aquifer-loss and well-loss parameters. In an SDT, different series of constant discharges with incremental rates are conducted to obtain incremental drawdowns in the pumping well. Pumping well efficiency (if the well is properly developed and designed) and discharge–drawdown relationship can then be derived from the SDT.
The aim of a constant discharge test (CDT) is to estimate hydraulic properties of an aquifer system such as transmissivity, hydraulic conductivity and storativity (storage coefficient).
Water Resources section at CEW has expert researchers for both SDT and CDT evaluation
Aquifer Storage and Recovery in Arid Areas
Aquifer Storage is a popular option to provide a reliable water supply. Injecting water into wells can prevent salt water intrusion into freshwater aquifers and control land subsidence. In contrast, ASR wells are used to store water in the ground and recover the stored water for drinking water supplies, irrigation, industrial needs, or ecosystem restoration projects.
Water Resources Section at CEW has expert researchers for Aquifer Storage and Recovery Projects
Groundwater Modeling for Water Resources Management
The most important thing to know about groundwater is that it provides us with the majority of the water we use for agricultural, domestic, municipal, and industrial uses. It is extremely important to characterize and understand the groundwater resources available to us in KSA. Groundwater Modeling is a first step tool designed to represent a simplified version of the field system (i.e. aquifer).
Water Resources section at CEW can build computer models that use numerical methods to characterize groundwater flow. MODFLOW models provide insight to determining sustainable aquifer yield and how to manage groundwater.
Artificial Intelligence (Ai) Research in Water Resources
Soft computing methods (also known as Artificial Intelligence) are playing a key role in the modelling of complex and nonlinear problems. The uncertainty associated with the data, the immense size of the data to deal with, the diversity of the data type and the associated scales are important factors to rely on unconventional mathematical tools such as soft computing.
Water Resources section at CEW can build soft computing models for flood prediction, water level mapping, runoff prediction etc.

Water Optimization Systems
One of the more difficult water challenges the oil and gas industry encounters is that produced and recovery of water must often be treated prior to disposal, reinjection or reuse. Because of the operating costs associated with most treatment systems can be high, the need for economical management of produced and recovery of water is especially critical.
